Abstract
Depression is a common and devastating neuropsychiatric symptom in the elderly and in patients with dementia. In particular, nearly 80% of patients with Alzheimer's Disease dementia experience depression during disease development and progression. However, it is unknown whether the depression in patients with dementia shares the same molecular mechanisms as depression presenting as primary psychiatric disease or occurs and persists through alternative mechanisms. In this review, we discuss how the clinical presentation and treatment differ between depression in dementia and as a primary psychiatric disease, with a focus on major depressive disorder. Then, we hypothesize several molecular mechanisms that may be unique to depression in dementia such as neuropathological changes, inflammation, and vascular events. Finally, we discuss existing issues and future directions for investigation and treatment of depression in dementia.

Abstract
Importance Late-life depressive symptoms are associated with subsequent dementia diagnosis and may be an early symptom or response to preclinical disease. Evaluating associations with early- and middle-life depression will help clarify whether depression influences dementia risk. Objective To examine associations of early-, middle-, and late-life depression with incident dementia. Design, Setting, and Participants This was a nationwide, population-based, cohort study conducted from April 2020 to March 2023. Participants included Danish citizens from the general population with depression diagnoses who were matched by sex and birth year to individuals with no depression diagnosis. Participants were followed up from 1977 to 2018. Excluded from analyses were individuals followed for less than 1 year, those younger than 18 years, or those with baseline dementia. Exposure Depression was defined using diagnostic codes from the International Classification of Diseases (ICD) within the Danish National Patient Registry (DNPR) and Danish Psychiatric Central Research Register (DPCRR). Main Outcomes and Measure Incident dementia was defined using ICD diagnostic codes within the DPCRR and DNPR. Cox proportional hazards regression was used to examine associations between depression and dementia adjusting for education, income, cardiovascular disease, chronic obstructive pulmonary disease, diabetes, anxiety disorders, stress disorders, substance use disorders, and bipolar disorder. Analyses were stratified by age at depression diagnosis, years since index date, and sex. Results There were 246 499 individuals (median [IQR] age, 50.8 [34.7-70.7] years; 159 421 women [64.7%]) with diagnosed depression and 1 190 302 individuals (median [IQR] age, 50.4 [34.6-70.0] years; 768 876 women [64.6%]) without depression. Approximately two-thirds of those diagnosed with depression were diagnosed before the age of 60 years (684 974 [67.7%]). The hazard of dementia among those diagnosed with depression was 2.41 times that of the comparison cohort (95% CI, 2.35-2.47). This association persisted when the time elapsed from the index date was longer than 20 to 39 years (hazard ratio [HR], 1.79; 95% CI, 1.58-2.04) and among those diagnosed with depression in early, middle, or late life (18-44 years: HR, 3.08; 95% CI, 2.64-3.58; 45-59 years: HR, 2.95; 95% CI, 2.75-3.17; ≥60 years: HR, 2.31; 95% CI, 2.25-2.38). The overall HR was greater for men (HR, 2.98; 95% CI, 2.84-3.12) than for women (HR, 2.21; 95% CI, 2.15-2.27). Conclusions and Relevance Results suggest that the risk of dementia was more than doubled for both men and women with diagnosed depression. The persistent association between dementia and depression diagnosed in early and middle life suggests that depression may increase dementia risk.

Abstract
Depression and anxiety are highly prevalent in most neurological disorders and can have a major impact on the patient's disability and quality of life. However, mostly due to the heterogeneity of symptoms and the complexity of the underlying comorbidities, depression can be difficult to diagnose, resulting in limited recognition and in undertreatment. The early detection and treatment of depression simultaneously with the neurological disorder is key to avoiding deterioration and further disability. Although the neurologist should be able to identify and treat depression initially, a neuropsychiatry team should be available for severe cases and those who are unresponsive to treatment. Neurologists should be also aware that in neurodegenerative diseases, such as Alzheimer's or Parkinson's, different depression symptoms could develop at different stages of the disease. The treatment options for depression in neurological diseases include drugs, cognitive-behavioral therapy, and somatic interventions, among others, but often, the evidence-based efficacy is limited and the results are highly variable. Here, we review recent research on the diagnosis and treatment of depression in the context of Alzheimer's disease, Parkinson's disease, and strokes, with the aim of identifying common approaches and solutions for its initial management by the neurologist.

Forgetful, sad and old: Do vascular cognitive impairment and depression share a common pre-disease network and how is it impacted by ageing? J Psychiatr Res 2022; 156:611-627. [PMID: 36372004 DOI: 10.1016/j.jpsychires.2022.10.071] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/06/2022] [Revised: 10/25/2022] [Accepted: 10/31/2022] [Indexed: 11/07/2022]
Abstract
Vascular cognitive impairment (VCI) and depression frequently coexist in geriatric populations and reciprocally increase disease risks. We assert that a shared pre-disease state of the psycho-immune-neuroendocrine (PINE) network model mechanistically explains bidirectional associations between VCI and depression. Five pathophysiological sub-networks are identified that are shared by VCI and depression: neuroinflammation, kynurenine pathway imbalance, hypothalamic-pituitary-adrenal (HPA) axis overactivity, impaired neurotrophic support and cerebrovascular dysfunction. These do not act independently, and their complex interactions necessitate a systems biology approach to better define disease pathogenesis. The PINE network is already established in the context of non-communicable diseases (NCDs) such as depression, hypertension, atherosclerosis, coronary heart disease and type 2 diabetes mellitus. We build on previous literature to specifically explore mechanistic links between MDD and VCI in the context of PINE pathways and discuss key mechanistic commonalities linking these comorbid conditions and identify a common pre-disease state which precedes transition to VCI and MDD. We expand the model to incorporate bidirectional interactions with biological ageing. Diathesis factors for both VCI and depression feed into this network and the culmination of shared mechanisms (on an ageing substrate) lead to a critical network transition to one or both disease states. A common pre-disease state underlying VCI and depression can provide clinicians a unique opportunity for early risk assessment and intervention in disease development. Establishing the mechanistic elements and systems biology of this network can reveal early warning or predictive biomarkers together with novel therapeutic targets. Integrative studies are recommended to elucidate the dynamic networked biology of VCI and depression over time.

Abstract
Caregivers of persons with dementia and depression experience adverse effects associated with their role. The aim of this scoping review was to identify the challenges faced by caregivers of people with dementia and depression, along with interventions to support them. The MEDLINE®, Embase and PsycINFO databases were searched using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. Grey literature was assessed using the Canadian Agency for Drugs and Technologies in Health's Gray Matter tool.The population consisted of caregivers of people with dementia and depression; the concept was to identify the negative impacts that caregivers experience and whether there are interventions to reduce them; the context was any study design targeting family or friends who were caregivers. A total of 12,835 citations were identified; 139 studies were included. Dementia and depression have variable impacts on outcomes experienced by caregivers, including burden/strain (n = 52), depression (n = 27), distress (n = 53), quality of life (n = 5) and health/well-being (n = 9). Pharmacological and non-pharmacological interventions have mixed effects. This study is important considering that depression in people with dementia is associated with caregiver distress. The use of a variety of non-pharmacological interventions could be beneficial to the latter.

Abstract
Depression is common in older individuals and is associated with high disability and increased mortality, yet the factors predicting late-life depression (LLD) are poorly understood. The relationship between of depressive disorder, age- and disease-related processes have generated pathogenic hypotheses and provided new treatment options. LLD syndrome is often related to a variety of vascular mechanisms, in particular hypertension, cerebral small vessel disease, white matter lesions, subcortical vascular impairment, and other processes (e.g., inflammation, neuroimmune regulatory dysmechanisms, neurodegenerative changes, amyloid accumulation) that may represent etiological factors by affecting frontolimbic and other neuronal networks predisposing to depression. The "vascular depression" hypothesis suggests that cerebrovascular disease (CVD) and vascular risk factors may predispose, induce or perpetuate geriatric depressive disorders. It is based on the presence of various cerebrovascular risk factors in many patients with LLD, its co-morbidity with cerebrovascular lesions, and the frequent development of depression after stroke. Other findings related to vascular depression are atrophy of the medial temporal cortex or generalized cortical atrophy that are usually associated with cognitive impairment. Other pathogenetic hypotheses of LLD, such as metabolic or inflammatory ones, are briefly discussed. Treatment planning should consider there may be a modest response to antidepressants, but several evidence-based and novel treatment options for LLD exist, such as electroconvulsive therapy, transcranial magnetic stimulation, neurobiology-based psychotherapy, as well as antihypertension and antiinflammatory drugs. However, their effectiveness needs further investigation, and new methodologies for prevention and treatment of depression in older individuals should be developed.

Abstract
Psychotherapy is one of the evidence-based clinical interventions for the treatment of depression in older adults with dementia. Randomised controlled trials are often the first methodological choice to gain evidence, yet they are not applicable to a wide range of humanistic psychotherapies. Amongst all, the efficacy of the Gestalt therapy (GT) is under-investigated. The purpose of this paper is to present a research protocol, aiming to assess the effects of a GT-based intervention on people with dementia (PWD) and indirect influence on their family carers. The study implements the single-case experimental design with time series analysis that will be carried out in Italy and Mexico. Six people in each country, who received a diagnosis of dementia and present depressive symptoms, will be recruited. Eight or more GT sessions will be provided, whose fidelity will be assessed by the GT fidelity scale. Quantitative outcome measures are foreseen for monitoring participants' depression, anxiety, quality of life, loneliness, carers' burden, and the caregiving dyad mutuality at baseline and follow-up. The advantages and limitations of the research design are considered. If GT will effectively result in the treatment of depression in PWD, it could enrich the range of evidence-based interventions provided by healthcare services.

Abstract
Repetitive transcranial magnetic stimulation (rTMS) with extensive 2-6-week protocols are applied to improve cognition and/or slow the cognitive decline seen in Alzheimer's Disease (AD). To date, there are no means to predict the response of a patient to rTMS treatment at baseline. Electrovestibulography (EVestG) biomarkers can be used to predict, at baseline, the efficacy of rTMS when applied to AD individuals. In a population of 27 AD patients (8 with significant cerebrovascular symptomatology, labelled ADcvd) EVestG signals were measured before and after rTMS treatment, and then compared with 16 age-matched healthy controls. MoCA was measured at baseline, whilst ADAS-Cog was the primary outcome measure. AD severity and comorbid cerebrovascular disease were treated as covariates. Using ADAS-Cog total score change, 13/27 AD/ADcvd patients improved with rTMS and 14/27 showed no-improvement. Leave-one-out-cross-validated linear-discriminant-analysis using two EVestG features yielded a blind accuracy of 75% for separating the improved and non-improved populations. Three-way separation of improved/non-improved/control accuracy was 91.9% using MoCA (67% alone) and one EVestG feature (66% alone). AD severity affects the rTMS treatment efficacy. The effect of existing significant cerebrovascular symptomatology on the efficacy of rTMS treatment remains unresolved. Baseline EVestG features can be predictive of the efficacy of rTMS treatment.

Abstract
The aetiopathogenesis of behaviours and psychological symptoms of dementia (BPSD) is often subjective, complex and multifaceted, produced by an array of contributing factors, including biomedical, psychological, environmental and/or social factors. Alongside other contributing factors, organic aetiology of BPSD should be considered when devising therapeutic management plans. Although considered last resort, time‐limited antipsychotic treatment (≤3 months) may have a vital adjunct role in managing intractable, refractory, distressing and/or life‐threatening BPSD, such as delusions and hallucinations; but only after person‐centred psychosocial interventions are exhausted and fail to deliver any therapeutic response. If prescribed, careful monitoring of therapeutic responses and adverse effects of antipsychotics with de‐prescribing plans should be a top priority, as these agents have limited efficacies and serious adverse outcomes (e.g., mortality).

Abstract
Dementia of vascular origin is a distinct variety with a heterogeneous neuropsychological profile. Very few studies have compared the behavioral dysfunction in the large vessel and small vessel vascular dementia (VaD) and studied the association between executive dysfunction and behavioral dysfunction documented in these patients, between the white matter load in small vessel disease (SVD) and the behavioral dysfunction. 76 patients having a modified Hachinski Ischemic Scale score of ≥ 4 were recruited and categorized into a small vessel and large vessel VaD. The Neuropsychiatric Inventory (NPI) score ≥ 4 per domain for defining clinically relevant symptoms and the Clinical Dementia Rating Scale (CDR) for evaluating the severity of dementia were used. Behavioral and Psychological Symptoms of Dementia (BPSD) were present in 66.67% of patients with SVD and 53.57% of those having large vessel disease. Apathy, euphoria, and disinhibition were more common in SVD, while appetite alterations were more common in large vessel disease. Behavioral dysfunction was also associated with executive dysfunction in both the VaD subtypes and with white matter loads in SVD. We conclude that different VaD subtypes have different behavioral profiles. This might help in understanding the underlying pathophysiology, diagnosis and thus better management of this disorder.

Abstract
The Memory Complaints Inventory (MCI) is a symptom validity measure designed to assess exaggerated memory complaints. The aim of current study was to develop memory complaint profiles on the MCI to distinguish between various neurocognitive disorders, depression, and non-credible performance. This study utilized MCI scores (N = 244) from a neuropsychology clinic to determine the presence of, and difference between, subjective memory complaints between a depression group, non-credible group, and subgroups of cognitive impairment (Alzheimer's Dementia, Vascular Dementia, and Mild Cognitive Impairment). Significant differences were found on MCI endorsement between cognitive impairment, depression, and non-credible groups. This pattern indicated fewer memory complaints for cognitive impairment groups when compared to depression and non-credible groups; the non-credible group had the highest MCI scores overall. ROC analyses revealed recommended clinical cutoff values with high specificity for distinguishing between the non-credible group and other groups. The findings provided further evidence for the MCI as a symptom validity measure, given its ability to differentiate between a non-credible group and clinical groups. Replication of the study's findings would result in reliable genuine subjective memory complaint profiles to provide additional diagnostic and prognostic specificity in neuropsychological practice.

Abstract
Late-life depression is associated with significant cognitive impairment. Meta-analyses showed that depression is associated with an increased risk for Alzheimer’s disease (AD) and it might be an etiological factor for AD. Since late-life depression is often connected with cognitive impairment and dementia is usually associated with depressive symptoms, a simple diagnostic approach to distinguish between the disorders is challenging. Several overlapping pathophysiological substrates might explain the comorbidity of both syndromes. Firstly, a stress syndrome, i.e., elevated cortisol levels, has been observed in up to 70% of depressed patients and also in AD pathology. Stress conditions can cause hippocampal neuronal damage as well as cognitive impairment. Secondly, the development of a depression and dementia after the onset of vascular diseases, the profile of cerebrovascular risk factors in both disorders and the impairments depending on the location of cerebrovascular lesions, speak in favor of a vascular hypothesis as a common factor for both disorders. Thirdly, neuroinflammatory processes play a key role in the etiology of depression as well as in dementia. Increased activation of microglia, changes in Transforming-Growth-Factor beta1 (TGF-beta1) signaling, production of pro-inflammatory cytokines as well as reduction of anti-inflammatory molecules are examples of common pathways impaired in dementia and depression. Fourthly, the neurotrophin BDNF is highly expressed in the central nervous system, especially in the hippocampus, where it plays a key role in the proliferation, differentiation and the maintenance of neuronal integrity throughout lifespan. It has been associated not only with antidepressant properties but also a reduction of cognitive impairment and therefore could be involved also in AD. Another etiologic factor is amyloid accumulation, as plasma amyloid beta-42 independently predicts both late-onset depression and AD. Higher plasma amyloid beta-42 predicts the development of late onset depression and conversion to possible AD. However, clinical trials with antibodies against beta amyloid recently failed, i.e., Solanezumab, Aducanumab, and Crenezumab. An overproduction of amyloid-beta might simply reflect a form of synaptic plasticity to compensate for neuronal dysfunction in different kind of neurological and psychiatric diseases of multiple etiologies. The tau hypothesis, sex/gender specific differences, epigenetics and the gut microbiota-brain axis imply other potential common pathways connecting late-life depression and dementia. In conclusion, different potential pathophysiological links between dementia and depression highlight several specific synergistic and multifaceted treatment possibilities, depending on the individual risk profile of the patient.

Association between Pulse Pressure and Onset of Dementia in an Elderly Korean Population: A Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17051657. [PMID: 32143342 PMCID: PMC7084760 DOI: 10.3390/ijerph17051657] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 02/24/2020] [Accepted: 02/29/2020] [Indexed: 01/27/2023]
Abstract
Objective: There is paucity of studies on the association between pulse pressure and the development of dementia, although this association has already been established. This study aimed at investigating the association between pulse pressure and the onset of dementia. Methods: We used the South Korean National Health Insurance Service claims cohort data to select 149,663 patients without dementia aged ≥60 years. We calculated adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for dementia using Cox proportional hazard models according to a pulse pressure classification (<50, 50-59, 60-69, 70-79, 80-89, or 90+). Results: Compared to women with pulse pressure <50, those with pulse pressures of 50-59, 60-69, and 90+ had higher HRs for dementia (1.14, 1.22, and 1.03, respectively). These associations were particularly strong in those on Medicaid insurance and from rural regions. However, there were no statistically significant results among men. Conclusions: A higher pulse pressure was associated with an elevated risk of dementia in women aged >60 years, particularly those on Medicaid and from rural regions, possibly due to their inability to access hypertension and other medical treatment. The establishment of dementia indicators will help to guide future health policies for the prevention of dementia.

Abstract
PURPOSE The aim of this study was to investigate the independent and combined association of incident depression and dementia with mortality and to explore whether the magnitude of the association varies according to different types of dementia, including Alzheimer's disease and vascular dementia. METHODS AND DESIGN The study was based on a population-based longitudinal cohort consisting of 9940 participants at baseline and followed for over 14 years. The sample used for the analyses included 6114 participants with available information on diagnosis of incident dementia and depression. For survival analyses, Cox regression models with incident dementia (n = 293; 5%) and incident depression (n = 746; 12%) as time-dependent variables were used. RESULTS Cox models adjusted for relevant confounders indicated that comorbidity of incident vascular dementia and incident depression was associated with a much higher mortality risk (HR 6.99; 95% CI 3.84-12.75) than vascular dementia in the absence of depression (HR 2.80; 95% CI 1.92-4.08). In contrast, estimates for comorbidity of Alzheimer's disease and depression were slightly lower than those for Alzheimer in absence of depression (HR 3.56; 95% CI 1.83-6.92 and HR 4.19; 95% CI 2.97-5.90, respectively). Incident depression in the absence of incident dementia was only weakly associated with mortality. CONCLUSIONS These findings indicate that depression and vascular dementia might have synergistic effects on mortality. The results have relevant public health implications for prevention, routine screening for and early treatment of depression among older people, especially those at risk of vascular dementia.

Abstract
Alzheimer's disease (AD) is characterized by progressive decline of cognition and associated neuropsychiatric signs including weight loss, anxiety, depression, agitation, and aggression, which is particularly pronounced in the female gender. Previously, we have shown that a novel ionic co-crystal of lithium salicylate proline (LISPRO) is an improved lithium formulation compared to the carbonate or salicylate form of lithium in terms of safety and efficacy in reducing AD pathology in Alzheimer's mice. The current study is designed to compare the prophylactic effects of LISPRO, lithium carbonate (LC), and lithium salicylate (LS) on cognitive and noncognitive impairments in female transgenic APPswe/PS1dE9 AD mice. Female APPswe/PS1dE9 mice at 4 months of age were orally treated with low-dose LISPRO, LS, or LC for 9 months at 2.25 mmol lithium/kg/day followed by determination of body weight, growth of internal organs, and cognitive and noncognitive behavior. No significant differences in body or internal organ weight, anxiety or locomotor activity were found between lithium treated and untreated APPswe/PS1dE9 cohorts. LISPRO, LC, and LS prevented spatial cognitive decline, as determined by Morris water maze and depression as determined by tail suspension test. In addition, LISPRO treatment was superior in preventing associative memory decline determined by contextual fear conditioning and reducing irritability determined by touch escape test in comparison with LC and LS. In conclusion, low-dose LISPRO, LC, and LS treatment prevent spatial cognitive decline and depression-like behavior, while LISPRO prevented hippocampal-dependent associative memory decline and irritability in APPswe/PS1dE9 mice.

Abstract
Depression is a common disorder among the elderly; however, it is not a standard element of the ageing process. Depression can affect oral health as a result of neglecting oral hygiene procedures, cariogenic nutrition, avoidance of necessary dental care which leads to an increased risk of dental caries and periodontal disease.Assessment of the relationship of oral health parameters with depression.500 subjects aged ≥65 (mean 74.4 ± 7.4) were involved in the study. Dental condition (decay-missing-filled index [DMFT], number of missing teeth [MT], removable denture wearing, teeth mobility), periodontal condition (bleeding on probing [BoP], pocket depth [PD], loss of attachment), oral dryness (the Challacombe Scale) and depression according to the Patient Health Questionnaire-9 (PHQ-9) scale were assessed.Depression on a minimal level was detected in 60.2% of the subjects, mild-in 22.2%, moderate-in 6.0% and moderately-in 2.6%. The mean of the PHQ-9 scale was 3.56 ± 4.07. Regression analysis showed a positive relationship of the PHQ-9 value with DMFT, the number of MT, oral dryness and with age. No correlation was observed between other examined oral health indicators, such as periodontal condition (BoP, PD, clinical attachment level), periodontitis, removable denture wearing a PHQ-9.The results of our study have shown that among people aged 65 and over, the severity of depression increases with a higher number of MT, the number of decayed teeth, as well as prevalence of oral dryness.

Abstract
BACKGROUND The dramatic shift in the global population demographic has led to increasing numbers of older people undergoing hospitalisation and surgical procedures. While necessary, these exposures may lead to an increase in depressive symptoms. OBJECTIVES To determine whether hospitalisation or hospitalisation with surgery under general anaesthesia is associated with an increase in depressive symptoms in adults over the age of 50. METHODS Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale in 8036 individuals at waves 1 and 2 of The Irish Longitudinal Study on Ageing (TILDA), 2 years apart. Mixed-effects models were used to investigate the hypothesis after adjustment for risk factors for depression and potential confounders. RESULTS During the 12 months preceding wave 1, a total of 459 participants were hospitalised (mean age, 67.0; 55.3% female), and a further 548 participants (mean age, 64.6; 51.8% female) were hospitalised and underwent surgery with general anaesthesia; 6891 (mean age, 63.5; 54.3% female) were not hospitalised. Analysis of waves 1 and 2 data using mixed-effects models demonstrated that there was a 7% increased adjusted incidence rate of depressive symptoms (IRR [95% CI] = 1.07 [1.02-1.11]) in the Center for Epidemiologic Studies Depression Scale in the hospitalisation group and a 4% increased adjusted incidence rate of depressive symptoms (IRR [95% CI] = 1.04 [1.00-1.08]) in the surgery group compared with those with no hospitalisation. CONCLUSION Hospitalisation and hospitalisation with surgery and general anaesthesia are associated with increased depressive symptoms. This is the first time a longitudinal population-representative study has demonstrated this relationship for both exposures simultaneously.

Abstract
OBJECTIVE To examine the association between the risks of depression and vascular dementia (VaD) based on Taiwan's National Health Insurance Research Database. METHODS This retrospective longitudinal matched-cohort study used National Health Insurance Research Database data from 49,955 participants (9,991 with new onset depression, 39,964 controls). A Cox regression analysis was performed on the whole sample and the subgroup of patients with depression. We further excluded patients who developed VaD within 3 or 5 years after enrollment to evaluate depression as an independent risk factor for or a prodrome of VaD. RESULTS During the 10-year follow-up period, the incidence rate ratio of VaD between patients with depression and controls was 4.24 [95% confidence interval (CI) 2.90-6.21, P < 0.001]. After adjustment for covariates, the hazard ratio (HR) of VaD in patients with depression was 3.10 (95% CI 2.13-4.52, P < 0.001). In the whole sample, risk factors for VaD besides depression were aged ≥60 years (HR = 20.08), hypertension (HR = 1.70), diabetes (HR = 1.61), coronary artery disease (HR = 2.26), head injury (HR = 2.20), and cerebrovascular disease (HR = 3.02). In patients with depression, aged ≥60 years (HR = 32.16), coronary artery disease (HR = 2.82), head injury (HR = 2.06), and cerebrovascular disease (HR = 2.37) remained risk factors for VaD. After excluding those who developed VaD within 3 or 5 years, HRs remained high (3.28, 95% CI 2.03-5.31, P < 0.001; 2.12, 95% CI 1.05-4.25, P = 0.035, respectively). CONCLUSIONS Our findings suggest that depression is an independent risk factor for subsequent VaD. Older age, cerebrovascular disease, head injury, and coronary artery disease might increase the risk of VaD among patients with depression.

Abstract
BACKGROUND Vascular depression is regarded as a subtype of late-life depression characterized by a distinct clinical presentation and an association with cerebrovascular damage. Although the term is commonly used in research settings, widely accepted diagnostic criteria are lacking and vascular depression is absent from formal psychiatric manuals such as the Diagnostic and Statistical Manual of Mental Disorders, 5th edition - a fact that limits its use in clinical settings. Magnetic resonance imaging (MRI) techniques, showing a variety of cerebrovascular lesions, including extensive white matter hyperintensities, subcortical microvascular lesions, lacunes, and microinfarcts, in patients with late life depression, led to the introduction of the term "MRI-defined vascular depression". DISCUSSION This diagnosis, based on clinical and MRI findings, suggests that vascular lesions lead to depression by disruption of frontal-subcortical-limbic networks involved in mood regulation. However, despite multiple MRI approaches to shed light on the spatiotemporal structural changes associated with late life depression, the causal relationship between brain changes, related lesions, and late life depression remains controversial. While postmortem studies of elderly persons who died from suicide revealed lacunes, small vessel, and Alzheimer-related pathologies, recent autopsy data challenged the role of these lesions in the pathogenesis of vascular depression. Current data propose that the vascular depression connotation should be reserved for depressed older patients with vascular pathology and evident cerebral involvement. Based on current knowledge, the correlations between intra vitam neuroimaging findings and their postmortem validity as well as the role of peripheral markers of vascular disease in late life depression are discussed. CONCLUSION The multifold pathogenesis of vascular depression as a possible subtype of late life depression needs further elucidation. There is a need for correlative clinical, intra vitam structural and functional MRI as well as postmortem MRI and neuropathological studies in order to confirm the relationship between clinical symptomatology and changes in specific brain regions related to depression. To elucidate the causal relationship between regional vascular brain changes and vascular depression, animal models could be helpful. Current treatment options include a combination of vasoactive drugs and antidepressants, but the outcomes are still unsatisfying.

Abstract
Depression in older women is a significant and growing problem. Women who experience life stressors across the life span are at higher risk for developing depression than their male counterparts. Research has focused primarily on identifying and reducing the symptoms of depression for the general aging population, disregarding gender-specific differences in the foundational causes of depression. This article examines how women's unique experiences influence the development of depression and highlights how the current mental health system could better meet older women's needs by moving from a gender-neutral model to one that emphasizes women's experiences.

Abstract
OBJECTIVES To compare locus of control and coping strategies in older persons with and without depression. METHOD This cross-sectional study included 144 depressed in-patients from seven psychogeriatric hospital units, and 106 community-dwelling older persons without depression. All participants were 60 years and older. Locus of control was assessed by a 17-items self-report questionnaire with six response categories. Coping strategies were assessed by a 26-items self-report questionnaire with five response categories. For analytical purposes, age (<75 years vs. ≥75 years), level of education (<10 years vs. ≥10 years) and general medical health (poor vs. not poor) were categorized. RESULTS In linear regression analysis, controlling for demographics, health, and social variables, the depressed in-patients showed a higher external locus of control orientation and a less frequent use of problem-focused coping strategies compared with the non-depressed group. No differences in use of emotion-focused strategies were found between the two groups. CONCLUSION Compared with the non-depressed old persons, the depressed hospitalized older persons were characterized by perceptions of less personal control, and less use of problem-focused strategies, what also might have brought positive alterations into their situation.

Abstract
BACKGROUND/AIMS To investigate the prevalence and trajectories of depressive symptomatology at 1-year follow-up, and the severity of depressive symptoms, by dementia diagnostic group, as well as to determine the predictors of depressive symptomatology at 1-year follow-up. METHODS In rural and remote patients of an interdisciplinary memory clinic between 2004 and 2014, 144 patients diagnosed with no cognitive impairment (NCI), mild cognitive impairment, dementia due to Alzheimer's disease (AD), or non-AD dementia completed the Center for Epidemiologic Studies of Depression Scale to assess depressive symptomatology at both time points. RESULTS Among patients with data at both time points, persistence of depressive symptomatology at follow-up occurred in 22.2%, remission in 17.4%, incidence in 13.2%, and absence in 47.2%. The prevalence of depressive symptomatology at baseline and persistence at follow-up were significantly greater in the NCI group than in the other diagnostic groups, but there were no differences in severity. Depressive symptomatology at follow-up was independently associated with depressive symptomatology, lower independence in activities of daily living, and lower self-rating of memory at baseline, as well as with decreased independence in activities of daily living between time points. CONCLUSION Future studies should further examine short-term postdiagnostic trajectories in depressive symptomatology in multiple dementia diagnostic groups to inform prognoses and treatment decisions.

Abstract
Articles describing older persons’ experiences of coping with severe depression are, to our knowledge, lacking. This article is methodologically grounded in phenomenological hermeneutics, inspired by Paul Ricoeur, and applies a descriptive design with in-depth interviews for producing the data. We included 18 older persons, 13 women and 5 men, with a mean age of 77.9 years, depressed to a severe or moderate degree, 1–2 weeks after admission to a hospital for treatment of depression. We found the metaphor “being in a vice” to capture the essence of meaning from the participants’ stories, and can be understood as being stuck in an immensely painful existence entirely dominated by depression in late life. This is the first article where coping in older men and women experiencing the most severe phase of depression is explored.

Abstract
Depression is very common throughout the course of veterans' lives, and dementia is common in late life. Previous studies suggest an association between depression and dementia in military veterans. The most likely biologic mechanisms that may link depression and dementia among military veterans include vascular disease, changes in glucocorticoid steroids and hippocampal atrophy, deposition of β-amyloid plaques, inflammatory changes, and alterations of nerve growth factors. In addition, military veterans often have depression comorbid with posttraumatic stress disorder or traumatic brain injury. Therefore, in military veterans, these hypothesized biologic pathways going from depression to dementia are more than likely influenced by trauma-related processes. Treatment strategies for depression, posttraumatic stress disorder, or traumatic brain injury could alter these pathways and as a result decrease the risk for dementia. Given the projected increase of dementia, as well as the projected increase in the older segment of the veteran population, in the future, it is critically important that we understand whether treatment for depression alone or combined with other regimens improves cognition. In this review, we summarize the principal mechanisms of this relationship and discuss treatment implications in military veterans.

Abstract
Background/Aims To estimate the prevalence, severity, and covariates of depressive symptoms in rural memory clinic patients diagnosed with either mild cognitive impairment (MCI) or dementia. Methods In a cross-sectional study of 216 rural individuals who attended an interdisciplinary memory clinic between March 2004 and July 2012, 51 patients were diagnosed with MCI and 165 with either dementia due to Alzheimer's disease (AD) or non-AD dementia. The Center for Epidemiologic Studies of Depression Scale (CES-D) was used to estimate the severity and prevalence of clinically elevated depressive symptomatology. Results The prevalence of elevated depressive symptoms was 51.0% in the MCI patients and 30.9% in the dementia patients. Depressive symptoms were more severe in the MCI patients than in the dementia patients. Elevated depressive symptoms were statistically associated with younger age for the MCI group, with lower self-rated memory for the dementia group, and with increased alcohol use and lower quality of life ratings for all patients. In the logistic regression models, elevated depressive symptoms remained negatively associated with self-rated memory and quality of life for the patients with dementia, but significant bivariate associations did not persist in the MCI group. Conclusions The high prevalence and severity of depressive symptoms among rural memory clinic patients diagnosed with either MCI or dementia warrant continued investigation.

Abstract
OBJECTIVES Depression in dementia is common, but the prevalence rates differ according to the populations studied and which diagnostic tools are being used. The aim of this study is to explore the prevalence of depression among patients referred to a memory clinic or an outpatient clinic as measured by the Cornell Scale of Depression in dementia (CSDD) and to investigate which factors are associated with depression. METHOD The CSDD was completed for 1470 patients on their first visit to a memory clinic or an outpatient clinic. The prevalence of depression using three different cut-off points was calculated. Logistic regression and correlation analyses were performed. RESULTS Half of the patients had dementia. The mean CSDD was 6.7 (SD: 5.3) for the whole group, and 50.2% had a score above 5, whereas 37.5% had depression defined as a CSDD score above 7, and 14.1% had a score above 12. The mean scores were higher among those with dementia other than Alzheimer's disease, those with previous depression, and those with greater impairment in the activities of daily living (ADL). In the logistic regression analyses, younger age, ADL dysfunction, and previous depression were significantly associated with higher CSDD scores. CONCLUSION We found that depressive symptoms are common among patients referred for a dementia assessment in specialist health care. The strongest factors associated with depressive symptoms were younger age, ADL impairment, and previous depression.

Abstract
PURPOSE The purpose of this study was to investigate the prevalence of depression and suicidal ideation in elders with dementia and to identify factors influencing their suicidal ideation. METHODS A descriptive and cross-sectional study was conducted from February to March, 2011. The participants were 298 older adults whose MMSE-KC score was 15 to 23. Collected Data were analyzed using t-test, ANOVA, Pearson correlation coefficients, and stepwise multiple regression. RESULTS According to the Geriatric Depression Scale (GDS) classification criteria, 86.2% of the elders in this study exhibited depression (GDS=5), and 31.5% manifested severe depression. The mean score of suicidal ideation was 5.70 (range 0-20). The risk factors for suicidal ideation were depression, suicidal attempt experience, present location for care, and activities of daily living. CONCLUSION The results of this study can be utilized in the development of suicide prevention programs for older adults with dementia. In particular, depression should be screened and managed to reduce suicidal ideation of older adults with dementia.

Abstract
OBJECTIVE To examine factors that impede or facilitate physicians' detection of depression in later life, including cognitive impairment and patients' endorsement of dysphoria. METHODS A population-based sample of 344 adults from the Swedish Adoption/Twin Study of Aging (SATSA) was utilized. Physician detection of depression was determined by (1) outpatient medical records, (2) antidepressant prescription, and/or (3) inpatient hospitalization. Depressive symptoms were measured by highest score on the Center for Epidemiologic Studies - Depression Scale (CES-D), administered on six occasions between 1986 and 1994. Endorsement of dysphoria was examined using two items on the CES-D. The Mini-Mental State Examination (MMSE) was used to indicate cognitive impairment. RESULTS One-hundred thirty-six individuals were above the cut-off on the CES-D on at least one occasion; however, only 14 of these individuals (10%) were detected as depressed by a physician. Higher CES-D total score was significantly related to physician detection. Furthermore, physicians were most likely to detect depression if the individual endorsed the single CES-D item regarding feeling depressed. A significant interaction was found, such that overall CES-D score was only associated with physician detection among those with higher endorsement of the depressed item. The association between total CES-D and physician detection was not affected by presence of cognitive impairment. CONCLUSIONS Depression in later life often goes undetected by physicians. Factors associated with detection include the frequency/severity of symptoms and patients' endorsement specifically of feeling depressed. Results suggest that physicians should routinely assess for other symptoms associated with late-life depression besides dysphoria (e.g., appetite loss, crying spells).

Abstract
BACKGROUND Previous epidemiological and clinical research on mental disorders has treated Blacks as a homogenous group and yet Blacks of Caribbean descent and African Americans differ with respect to ethnicity, national heritage, living circumstances, and immigration status. The purpose of this article is to examine the prevalence of major depressive disorder (MDD) among African Americans, Caribbean Blacks, and non-Hispanic whites aged 50 and older with data on psychiatric and physical comorbidity, mental illness severity, and service use. METHODS Secondary analysis of data from the National Survey of American Life, a national household probability sample of African Americans, Caribbean Blacks, and non-Hispanic Whites in the United States, were used (n = 1,950). The response rate was 72.3%. RESULTS Controlling for age, the lifetime prevalence rate of MDD was 12.1% and the 12-month rate was 5.2%. Older Whites and Caribbean Blacks had significantly higher lifetime prevalence than African Americans but 12-month rates were similar across the three groups. Rates of co-occurring psychiatric disorders and physical conditions were high and were similar for African Americans, Caribbean Blacks, and Whites. Most older adults had either moderate or severe 12-month MDD and most talked to at least one professional, most frequently a family doctor, psychiatrist, or other mental health professional. CONCLUSION MDD among older adults is highly prevalent, often associated with other psychiatric disorders or chronic physical conditions, and is associated with high overall mental illness severity. Differences among older Blacks highlight the need for further research on this population to ensure appropriate treatment is being provided to these groups.

Abstract
Major depressive disorder (MDD) is marked by disturbances in brain functional connectivity. This connectivity is modulated by rhythmic oscillations of brain electrical activity, which enable coordinated functions across brain regions. Oscillatory activity plays a central role in regulating thinking and memory, mood, cerebral blood flow, and neurotransmitter levels, and restoration of normal oscillatory patterns is associated with effective treatment of MDD. Repetitive transcranial magnetic stimulation (rTMS) is a robust treatment for MDD, but the mechanism of action (MOA) of its benefits for mood disorders remains incompletely understood. Benefits of rTMS have been tied to enhanced neuroplasticity in specific brain pathways. We summarize here the evidence that rTMS entrains and resets thalamocortical oscillators, normalizes regulation and facilitates reemergence of intrinsic cerebral rhythms, and through this mechanism restores normal brain function. This entrainment and resetting may be a critical step in engendering neuroplastic changes and the antidepressant effects of rTMS. It may be possible to modify the method of rTMS administration to enhance this MOA and achieve better antidepressant effectiveness. We propose that rTMS can be administered: (1) synchronized to a patient's individual alpha frequency (IAF), or synchronized rTMS (sTMS); (2) as a low magnetic field strength sinusoidal waveform; and, (3) broadly to multiple brain areas simultaneously. We present here the theory and evidence indicating that these modifications could enhance the therapeutic effectiveness of rTMS for the treatment of MDD.

Abstract
CONTEXT Depression and dementia are common in older adults and often co-occur, but it is unclear whether depression is an etiologic risk factor for dementia. OBJECTIVE To clarify the timing and nature of the association between depression and dementia. DESIGN We examined depressive symptoms assessed in midlife (1964-1973) and late life (1994-2000) and the risks of dementia, Alzheimer disease (AD), and vascular dementia (VaD) (2003-2009) in a retrospective cohort study. Depressive symptoms were categorized as none, midlife only, late life only, or both. Cox proportional hazards models (age as timescale) adjusted for demographics and medical comorbidities were used to examine depressive symptom category and risk of dementia, AD, or VaD. SETTING Kaiser Permanente Medical Care Program of Northern California. PARTICIPANTS Thirteen thousand five hundred thirty-five long-term Kaiser Permanente members. MAIN OUTCOME MEASURE Any medical record diagnosis of dementia or neurology clinic diagnosis of AD or VaD. RESULTS Subjects had a mean (SD) age of 81.1 (4.5) years in 2003, 57.9% were women, and 24.2% were nonwhite. Depressive symptoms were present in 14.1% of subjects in midlife only, 9.2% in late life only, and 4.2% in both. During 6 years of follow-up, 22.5% were diagnosed with dementia (5.5% with AD and 2.3% with VaD). The adjusted hazard of dementia was increased by approximately 20% for midlife depressive symptoms only (hazard ratio, 1.19 [95% CI, 1.07-1.32]), 70% for late-life symptoms only (1.72 [1.54-1.92]), and 80% for both (1.77 [1.52-2.06]). When we examined AD and VaD separately, subjects with late-life depressive symptoms only had a 2-fold increase in AD risk (hazard ratio, 2.06 [95% CI, 1.67-2.55]), whereas subjects with midlife and late-life symptoms had more than a 3-fold increase in VaD risk (3.51 [2.44-5.05]). CONCLUSIONS Depressive symptoms in midlife or in late life are associated with an increased risk of developing dementia. Depression that begins in late life may be part of the AD prodrome, while recurrent depression may be etiologically associated with increased risk of VaD.

Abstract
We have already entered a new, more exciting, and hopeful era in the treatment of late-life depression. The increasing numbers of older adults who are surviving to more advanced ages and the greater recognition of late-life depression’s prevalence and impact on quality of life emphasize how important it is to detect and treat this disorder. Our increasing repertoire of evidence-based psychotherapeutic, pharmacologic, and neurotherapeutic treatment interventions offers many treatment alternatives, allowing substantial individualization of treatment approach. Demonstration of the effectiveness of depression treatment in primary care suggests the feasibility of increasing our patients’ access to care. Growing appreciation of the pathophysiology of depression and its interrelationships with cognitive impairment may increase our ability to limit or delay certain aspects of cognitive impairment through more aggressive treatment of depression. Improved recognition and treatment of late-life depression holds great potential for improving physical and mental health in later life, reducing disability in later years, and improving quality of life.

Abstract
Background This study explores factors associated with depression in Alzheimer's disease (AD) compared with mild cognitive impairment (MCI) and other dementia disorders. Method In a prospective study we included 195 patients: 31 with MCI, 112 with AD and 52 with other dementias. Results According to the ICD-10 and the DSM-IV criteria, 88 (44.1%) and 59 (30.3%), respectively, had a depressive disorder. An adjusted multiple regression analysis showed that previous depression (p < 0.05) was significantly associated with depression in AD patients. Severity of dementia (p < 0.05) was significantly associated with a depressive disorder in a group of patients with frontotemporal dementia, vascular dementia, or dementia due to Lewy Body disease or Parkinson's disease. Conclusion We found different factors associated with a depressive disorder in AD compared to those found for other dementia disorders.

Biomarkers for major depression and its delineation from neurodegenerative disorders. Prog Neurobiol 2011; 95:703-17. [PMID: 21854829 DOI: 10.1016/j.pneurobio.2011.08.001] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2011] [Revised: 06/24/2011] [Accepted: 08/04/2011] [Indexed: 12/14/2022]
Abstract
Major depressive disorders (MDD) are among the most debilitating diseases worldwide and occur with a high prevalence in elderly individuals. Neurodegenerative diseases (in particular Alzheimer's disease, AD) do also show a strong age-dependent increase in incidence and prevalence among the elderly population. A high number of geriatric patients with MDD show cognitive deficits and a very high proportion of AD patients present co-morbid MDD, which poses difficult diagnostic and prognostic questions. Especially in prodromal and in very early stages of AD, it is almost impossible to differentiate between pure MDD and MDD with underlying AD. Here, we give a comprehensive review of the literature on the current state of candidate biomarkers for MDD ("positive MDD markers") and briefly refer to established and validated diagnostic AD biomarkers in order to rule out underlying AD pathophysiology in elderly MDD subjects with cognitive impairments ("negative MDD biomarkers"). In summary, to date there is no evidence for positive diagnostic MDD biomarkers and the only way to delineate MDD from AD is to use "negative MDD" biomarkers. Because of this highly unsatisfactory current state of MDD biomarker research, we propose a research strategy targeting to detect and validate positive MDD biomarkers, which is based on a complex (genetic, molecular and neurophysiological) biological model that incorporates current state of the art knowledge on the pathobiology of MDD. This model delineates common pathways and the intersection between AD and MDD. Applying these concepts to MDD gives hope that positive MDD biomarkers can be successfully identified in the near future.

Dai B, Li J, Cuijpers P. Psychological treatment of depressive symptoms in Chinese elderly inpatients with significant medical comorbidity: a meta-analysis. BMC Psychiatry 2011; 11:92.

Abstract
BACKGROUND As it is uncertain whether psychological treatments for depressive symptoms are effective in elderly inpatients with significant medical comorbidity, we aimed to assess the treatment effectiveness not only on depressive symptoms but also on somatic symptoms in these inpatients. METHODS We performed a meta-analysis of randomized controlled studies assessing the effects of psychological treatments in Chinese older inpatients with significant medical comorbidity based upon extensive searches of the most comprehensive computerized Chinese academic database. RESULTS The overall effect size for depressive symptoms of twelve studies which compared psychological treatments with a care-as-usual control group was d = 0.80 (95% Confidence Intervals (CI) = 0.60-0.99; p < 0.001). The relative risk of psychological intervention of being effective or not, compared to control condition, was 1.52 (95% CI = 1.25-1.85; p < 0.001). CONCLUSIONS We conclude that psychological treatments of depressive symptoms are effective for Chinese elderly inpatients with significant medical comorbidity which should receive more attention in medical settings.

Abstract
Depression is highly common throughout the life course and dementia is common in late life. Depression has been linked with dementia, and growing evidence implies that the timing of depression may be important in defining the nature of this association. In particular, earlier-life depression (or depressive symptoms) has consistently been associated with a more than twofold increase in dementia risk. By contrast, studies of late-life depression and dementia risk have been conflicting; most support an association, yet the nature of this association (for example, if depression is a prodrome or consequence of, or risk factor for dementia) remains unclear. The likely biological mechanisms linking depression to dementia include vascular disease, alterations in glucocorticoid steroid levels and hippocampal atrophy, increased deposition of amyloid-β plaques, inflammatory changes, and deficits of nerve growth factors. Treatment strategies for depression could interfere with these pathways and alter the risk of dementia. Given the projected increase in dementia incidence in the coming decades, understanding whether treatment for depression alone, or combined with other regimens, improves cognition is of critical importance. In this Review, we summarize and analyze current evidence linking late-life and earlier-life depression and dementia, and discuss the primary underlying mechanisms and implications for treatment.

Abstract
BACKGROUND Previous studies have attempted to provide estimates of depression prevalence in older adults. The Aging, Demographics and Memory Study (ADAMS) is a population-representative study that included a depression assessment, providing an opportunity to estimate the prevalence of depression in late life in the U.S.A. METHODS The ADAMS sample was drawn from the larger Health and Retirement Study. A total of 851 of 856 ADAMS participants aged 71 and older had available depression data. Depression was measured using the Composite International Diagnostic Interview - Short Form (CIDI-SF) and the informant depression section of the Neuropsychiatric Inventory (NPI). We estimated the national prevalence of depression, stratified by age, race, sex, and cognitive status. Logistic regression analyses were performed to examine the association of depression and previously reported risk factors for the condition. RESULTS When combining symptoms of major or minor depression with reported treatment for depression, we found an overall depression prevalence of 11.19%. Prevalence was similar for men (10.19%) and women (11.44%). Whites and Hispanics had nearly three times the prevalence of depression found in African-Americans. Dementia diagnosis and pain severity were associated with increased depression prevalence, while black race was associated with lower rates of depression. CONCLUSIONS The finding of similar prevalence estimates for depression in men and women was not consistent with prior research that has shown a female predominance. Given the population-representativeness of our sample, similar depression rates between the sexes in ADAMS may result from racial, ethnic and socioeconomic diversity.

Comorbid depression in dementia on psychogeriatric nursing home wards: which symptoms are prominent? Am J Geriatr Psychiatry 2009; 17:565-73. [PMID: 19554671 DOI: 10.1097/jgp.0b013e31819a806f] [Citation(s) in RCA: 45] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 11/25/2022]
Abstract
OBJECTIVE To provide insight into the prevalence and clinically relevant symptoms of comorbid depression among dementia patients in psychogeriatric nursing home wards, to enhance depression recognition. DESIGN Cross-sectional analyses of multicenter diagnostic data. SETTING Psychogeriatric wards of Dutch nursing homes. PARTICIPANTS Five hundred and eighteen residents with dementia. MEASUREMENTS 1) Diagnosis of depression in dementia (Provisional Diagnostic Criteria for Depression of Alzheimer disease [PDC-dAD]), 2) dementia (Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-PC), and 3) stage of dementia (Geriatric Depression Scale). RESULTS The point prevalence of comorbid depression in dementia (Stages 2-6) on psychogeriatric nursing home wards was 19%. "Depressed mood," "irritability," and "fatigue" were the most prevalent depressive symptoms. Residents taking antidepressants at the time of the PDC-dAD depression diagnosis showed more depressive symptoms than residents who were not. The mean number of depressive symptoms was 5.6 (SD 1.84), which did not differ between the dementia stages. Also, no differences were found in the point prevalence of the shown symptoms between dementia stages. CONCLUSION Irritability was put forward by the developers of the PDC-dAD, as one of the specific symptoms of depression in Alzheimer disease. This study shows that irritability is one of the most prevalent depressive symptoms in psychogeriatric nursing home residents diagnosed with comorbid depression. Irritability should therefore alert caregivers to the presence of depression and could help early recognition. The high-prevalence rate of comorbid depression in dementia in this setting justifies attention to early recognition and intervention.

Abstract
Depression is less prevalent among older adults than among younger adults, but it can have serious consequences. More than half of cases represent a first onset in later life. Although suicide rates in the elderly are declining, they are still higher than in younger adults and are more closely associated with depression. Depressed older adults are less likely to endorse affective symptoms and more likely to display cognitive changes, somatic symptoms, and loss of interest than are depressed younger adults. Risk factors leading to the development of late-life depression likely comprise complex interactions among genetic vulnerabilities, cognitive diathesis, age-associated neurobiological changes, and stressful events. Insomnia is an often overlooked risk factor for late-life depression. We suggest that a common pathway to depression in older adults, regardless of which predisposing risks are most prominent, may be curtailment of daily activities. Accompanying self-critical thinking may exacerbate and maintain a depressed state. Offsetting the increasing prevalence of certain risk factors in late life are age-related increases in psychological resilience. Other protective factors include higher education and socioeconomic status, engagement in valued activities, and religious or spiritual involvement. Treatments including behavioral therapy, cognitive-behavioral therapy, cognitive bibliotherapy, problem-solving therapy, brief psychodynamic therapy, and life review/reminiscence therapy are effective but are too infrequently used with older adults. Preventive interventions including education for individuals with chronic illness, behavioral activation, cognitive restructuring, problem-solving skills training, group support, and life review have also received support.

Abstract
There is a strong association between late-life depression, cognitive impairment, cerebrovascular disease, and poor cognitive outcomes, including progressive dementia, especially Alzheimer's disease. While neuroimaging evidence suggests that cerebrovascular disease plays a prominent role, it seems that depression alone may also confer substantial risk for developing Alzheimer's disease. The relationships between the prominent cerebrovascular changes, other structural abnormalities, specific forms of cognitive dysfunction, and increased risk for developing Alzheimer's disease among those with late-life depression have been difficult to reconcile. The varied findings suggest that there are likely multiple pathways to poor cognitive outcomes. We present a framework outlining multiple, non-mutually exclusive etiologic links between depression, cognitive impairment, and progressive decline, including dementia. Importantly, the model is both testable and falsifiable. Going forward, using models such as this to inform research should accelerate knowledge acquisition on the depression/dementia relationship that may be useful for dementia prevention, monitoring the impact of depression treatment on clinical status and course of illness.

Abstract
BACKGROUND Depressive symptoms in the elderly are associated with an increased Alzheimer's disease (AD) risk. We sought to determine whether the association between depressive symptoms and AD is explained by a history of vascular risk factors and stroke. METHODS Five hundred and twenty-six elderly persons from New York City without dementia at baseline were followed for a mean of 5 years. Depressive symptoms were assessed using the 17-item Hamilton Depression Rating Scale (HAM). Incident AD was ascertained using standard criteria. Diabetes, hypertension, heart disease, current smoking and stroke were ascertained by self-report. Proportional hazards regression was used to relate HAM scores to incident AD. RESULTS HAM scores were higher in persons with hypertension, heart disease, and stroke, which in turn were related to higher AD risk. AD risk increased with increasing HAM scores as a continuous logarithmically transformed variable (HR for one point increase=1.4; 95% CI=1.1,1.8) and as a categorical variable (HR for HAM >or= 10=3.4; 95% CI=1.5,8.1; p for trend=0.004 with HAM=0 as the reference). These results were virtually unchanged after adjustment for vascular risk factors and stroke, individually (HR for HAM >or= 10=3.4; 95% CI=1.5,8.1; p for trend = 0.004), and in a composite measure (HR for HAM >or= 10=3.0; 95% CI=1.2,7.8; p for trend=0.02). CONCLUSION The prospective relation between depressive symptoms and AD is not explained by a history of vascular risk factors and stroke, suggesting that other mechanisms may account for this association.

Abstract
Disentangling depression from dementia remains one of the most difficult clinical challenges for psychiatrists caring for older adults. The relationship between geriatric depression and dementia is complex for several reasons. First, cognitive impairment is often a prominent feature of depression in the elderly. Cognition may improve with successful treatment of depression but it may not normalize. Indeed, marked memory impairment in older depressed individuals may indicate a prodromal state of dementia. This review will examine issues related to depression and cognitive disorder in the elderly. The author will provide an evidence-based approach to separate mood disorder from cognitive disorder among older adults.

Abstract
Cognitive impairment is common in geriatric depression, and depressed individuals with co-morbid cognitive impairment are at increased risk for a number of adverse medical, psychiatric and cognitive outcomes. This review focuses on clinical issues surrounding the co-occurrence of these two conditions within the context of current research. We (1) review the clinical criteria and prevalence of depression, as well as co-morbid cognitive impairment, (2) discuss factors associated with persistent cognitive impairment in depression, including dementia, and (3) review research relevant to the assessment and treatment of cognitive impairment and dementia in the context of depression. We conclude that current research on depression and cognition can inform clinical decisions that reduce the occurrence of adverse outcomes. Clinicians are encouraged to develop proactive approaches for treatment, which may include combinations of pharmacological and psychotherapeutic interventions.
