J Psychiatr Res 2022; 151:546-553. [PMID: 35636030 PMCID: PMC9126310 DOI: 10.1016/j.jpsychires.2022.05.042] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 03/04/2022] [Accepted: 05/20/2022] [Indexed: 12/14/2022]
Abstract
Loneliness was deemed a behavioral epidemic even prior to the COVID-19 pandemic. The COVID-19 pandemic and the subsequent social distancing policy measures have raised concerns about increased social isolation and loneliness, especially in vulnerable populations such as military veterans. However, little is known about the impact of the pandemic on longitudinal changes in loneliness in veterans, and potential protective psychosocial factors that may mitigate loneliness in this population. We analyzed data from the 2019-2020 National Health and Resilience in Veterans Study, which surveyed a nationally representative, prospective cohort of 3,078 US veterans before and 1-year into the pandemic. Prevalence, and risk and protective factors associated with changes in loneliness were examined. Results revealed that the prevalence of loneliness decreased over the study period-17.3% pre-pandemic to 15.9% peri-pandemic (p = 0.032). A total of 5.4% (n = 164) of veterans reported increased loneliness, 6.4% (n = 196) decreased loneliness, and 10.6% (n = 325) persistent loneliness during the pandemic. Multivariable logistic regression models indicated that not being married/partnered, and scoring lower on pre-pandemic measures of purpose in life and cognitive functioning were most strongly associated with increased loneliness. Pre-pandemic psychiatric disorder, unpartnered marital status, and pandemic-related social restriction and financial stressors were most strongly associated with persistent loneliness. Collectively, these results suggest that, contrary to concerns, the prevalence of loneliness subtly decreased one year into the pandemic. Veterans who are not partnered, have pre-existing psychiatric conditions, and endorse more COVID-related stressors may be at higher risk for experiencing loneliness during the pandemic. Interventions that promote social connectedness, as well as that target the aforementioned risk and protective factors, may help mitigate loneliness in veterans.

Abstract
Aging and its associated problems related to movement impacts the care of people with psychiatric disorders. This study sought to clarify the usefulness of 2D video analysis for evaluating shoulder range of motion (ROM) during upper limb exercises in patients with psychiatric disorders. Subjects (N=54) were patients with psychiatric disorders categorized as the following:having either a high or low activities of daily living (ADL) score using the Barthel Index;experiencing shoulder ROM limitation, and whether or not compensatory movements were exhibited. Compensatory movement was also considered in patients with Parkinsonism, cerebrovascular disease, and cognitive dysfunction. Shoulder joint ROM was measured using a goniometer and active ROM was captured using ImageJ. No significant difference between passive ROM measured by a goniometer and active ROM measured by ImageJ considering disease groups, ADL level, and shoulder ROM limitation was found. Factoring in compensatory movements, however, significant differences were found between passive and active ROM:existence compensatory movement group, left side (z=-2.30, p=0.02);nonexistence compensatory movement group, right side (z=-2.63, p<0.001). Image-evaluating devices help assess ROM in patients with psychiatric disorders, enhancing the development of physical rehabilitation programs to regain critical ADL, sustaining self-care capabilities.

Implications for global public health campaigns: a cross-sectional study. BMC Public Health 2021; 21:693. [PMID: 33836715 PMCID: PMC8034077 DOI: 10.1186/s12889-021-10689-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Accepted: 03/23/2021] [Indexed: 01/17/2023] Open
Abstract
Background Cultural differences in affective and cognitive intrinsic motivation could pose challenges for global public health campaigns, which use cognitive or affective goals to evoke desired attitudes and proactive health-promoting actions. This study aimed to identify cross-cultural differences in affective and cognitive intrinsic motivation and discuss the potential value of this information for public health promotion. Methods A cross-sectional survey using cross-culturally validated need for affect (NFA) and need for cognition (NFC) scales was carried out among 1166 Chinese participants, and the results were compared with published data from 980 American participants. Additionally, we assessed a highly prevalent symbolic geriatric health condition, hearing loss, in 500 Chinese community-dwelling seniors. The Chinese NFA scale was developed following the translation-back translation procedure, and the psychometric evaluation was performed by applying confirmatory factor analysis (CFA), exploratory structural equation modeling (ESEM), correlation analysis and multigroup invariance test. MANOVA and Hedge’s g statistic were employed to compare the NFA and NFC levels between individuals from different countries and between Chinese seniors with and without hearing loss. The relation of early hearing intervention intention to NFA and NFC was also explored in the Chinese sample. Results A basic two-factor model of NFA adequately fit the sample data from Chinese and American cultures. The questionnaire demonstrated reasonable invariance of the factor structure and factor loadings across the groups. Those in the primary Chinese sample had lower NFA and NFC than their American peers. This difference held in the senior sample. Moreover, Chinese seniors with hearing loss had even lower NFA and NFC than those without hearing loss. Their early hearing intervention intention was low but was associated with intrinsic motivation. Conclusions The Need for Affect (NFA) construct may be generalized beyond its Western origins. There was a general lack of affective and cognitive intrinsic motivation in Chinese individuals, particularly in seniors with hearing loss, compared with their American peers. These differences point to a potential challenge in framing effective messages for some cultures in the geriatric public health domain. Ideally, recognizing and understanding this challenge will inspire the consideration of novel persuasive strategies for these audiences.

Abstract
BACKGROUND In the last three decades, the relationship between depression and cognition in geriatric patients has been a popular topic among researchers and clinicians. Clinical and epidemiological research has focused on the identification of risk factors that could be modified in pre-dementia syndromes, at a preclinical and early clinical stage of dementia disorders, with specific attention to the role of depression. The objective of this work was to determine the relationship between depressive disorder and cognitive deterioration in institutionalized older adults. METHODS In this descriptive, correlational study, data were gathered from two nursing homes in the province of Jaen (Spain), from a random sample of 140 older adults (70 nondependent and 70 dependent). The variables were measured using comprehensive geriatric assessment, the Cambridge Cognitive Test (CAMCOG), and the Geriatric Depression Scale (GDS). RESULTS Depression was correlated with cognitive level in the nondependent older adult sample (r = -0.471, p = 0.004). Age was inversely associated with the score obtained in the CAMCOG of the nondependent older adult sample (r = -0.352, p = 0.038). The functional capacity in several activities of daily living was correlated with the score obtained in the CAMCOG in each of the two groups. Depression was more prevalent in the dependent than in the nondependent older adults (82.85 vs. 57.14%). No association was observed between institutionalization time and the score obtained on the cognitive and affective scales (GDS and CAMCOG) in both groups (GDS-nondependent, r = -0.209, p = 0.234; CAMCOG-nondependent, r = 0.007, p = 0.967; GDS-dependent, r = 0.251, p = 0.152; CAMCOG-dependent, r = -0.021, p = 0.907). CONCLUSION Depressive symptomatology is associated with cognitive deterioration. Depression is prevalent in institutions that care for older, more dependent adults.

The Effect of Cochlear Implants on Cognitive Function in Older Adults: Initial Baseline and 18-Month Follow Up Results for a Prospective International Longitudinal Study. Front Neurosci 2019; 13:789. [PMID: 31427915 PMCID: PMC6687844 DOI: 10.3389/fnins.2019.00789] [Citation(s) in RCA: 60] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2018] [Accepted: 07/15/2019] [Indexed: 01/09/2023] Open
Abstract
In older adults, hearing loss is independently associated with an increased rate of cognitive decline, and has been identified to be a modifiable risk factor for dementia. The mechanism underlying the cognitive decline associated with hearing loss is not understood, but it is known that the greater the hearing loss, the faster the rate of decline. It is unknown whether remediation of hearing loss with hearing devices can delay cognitive decline. This 5-year international longitudinal study is investigating the impact of cochlear implants on cognitive function in older people with severe-profound hearing loss, and whether remediation of hearing loss could delay the onset of cognitive impairment. This is the first study to examine the major primary risk factors associated with dementia in the same cohort. Participants were assessed before cochlear implantation and 18 months later using an identical battery including a visually presented cognitive assessment tool (Cogstate battery) that is highly sensitive to small changes in cognition and suitable for use with people with hearing loss. Hearing and speech perception ability were assessed in sound-treated conditions by an audiologist, and a range of questionnaire tools was administered to assess self-perceived ease of listening, quality of life, physical activity, diet, social and emotional loneliness, isolation, anxiety, and depression. A detailed medical health history was taken. Pre-operatively, despite the small initial sample size (n = 59), increased hearing loss and age predicted significantly poorer executive function and visual attention, while tertiary education predicted better executive function. Better self-reported quality of life was correlated with better visual learning performance, and engaging in frequent vigorous physical activity was correlated with poorer visual learning performance. At 18 months, for the first 20 participants, significant benefits of cochlear implants were seen in terms of speech perception, communication ability, and quality of life. Multiple linear regression modeling showed executive function improved significantly for non-tertiary educated males, while cognitive function remained stable for other participants. Further follow-up at 18 month intervals with a larger sample will reveal the effects of cochlear implant intervention on all outcomes, and whether this can delay cognitive decline.

Abstract
Transcranial magnetic stimulation may represent an effective means for improving motor function in the elderly. The aim of this study was therefore to investigate the effects of paired associative stimulation (PAS; a plasticity-inducing transcranial magnetic stimulation paradigm) on acquisition of a novel visuomotor task in young and older adults. Fourteen young (20.4 ± 0.6 years) and 13 older (69.0 ± 1.6 years) adults participated in 3 experimental sessions during which training was preceded (primed) by PAS. Within each session, the interstimulus interval used for PAS was set at either the N20 latency plus 5 ms (PASLTP), the N20 latency minus 10 ms (PASLTD), or a constant 100 ms (PASControl). After training, the level of motor skill was not different between PAS conditions in young subjects (all p-values > 0.2), but was reduced by both PASLTP (p = 0.02) and PASLTD (p = 0.0001) in older subjects. Consequently, priming PAS was detrimental to skill acquisition in older adults, possibly suggesting a need for interventions that are optimized for use in elderly populations.

Abstract
OBJECTIVES To investigate the predictive value of symptoms of dementia that the person or an informant noticed spontaneously in determining the clinical severity of dementia. DESIGN Cross-sectional. SETTING Community-based open-referral dementia assessment service in Hong Kong between 2005 and 2013. PARTICIPANTS Help-seekers for dementia assessment service and their informants (N = 965 dyads). MEASUREMENTS Participants underwent a clinical dementia interview based on the Clinical Dementia Rating. Spontaneous complaints that the person and the informant made that had prompted their help-seeking of groups with interview results suggestive of no impairment, mild cognitive impairment, and dementia were compared. Logistic regression was used to evaluate the predictive value of spontaneous complaints for clinical severity. Independent raters blinded to clinical results coded spontaneously reported symptoms into theoretical themes: memory, executive function, language, time and place orientation, neuropsychiatric, mood, and avolition. RESULTS Memory problems were the most frequently reported complaints for participants (87.7%) and their informants (95.5%), followed by self-reported language (33.0%) and informant-reported orientation (33.0%) difficulties. Informant-reported but not self-reported symptoms predicted clinical severity. Compared with the persons themselves, informants reported more pervasive symptoms corresponding to clinical severity. Persons with dementia self-reported fewer types of symptoms than their healthy or mildly impaired counterparts. Spontaneously reported language and orientation symptoms by the informant distinguished persons with mild or worse dementia (P < .001, Nagelkerke coefficient of determination = 29.7%, percentage correct 85.6%). CONCLUSION The type and pervasiveness of symptoms spontaneously that informants reported predicted clinical severity. This may provide a quick reference for triage.

Abstract
OBJECTIVE To examine the relationships over time between dual trajectories of depressive symptoms and several cognitive domains. METHODS In a 5-year longitudinal study, 1,978 randomly selected individuals aged 65+ years at recruitment were assessed annually. Repeated measures were of depressive symptoms on the modified Center for Epidemiologic Studies Depression Scale and composite scores in the cognitive domains of attention, executive function, memory, language, and visuospatial function. Latent class trajectories were identified for depression and for each cognitive domain and their associations investigated using dual trajectory modeling. Cognitive trajectories with z scores below -1 were designated as persistently low. RESULTS Five depressive symptom trajectories were observed: rarely depressed (60.5%); low-grade, decreasing symptoms (18.5%); low-grade, increasing symptoms (9.6%); moderate-grade symptoms (7.4%); and consistent higher-grade symptoms (4.0%). For each cognitive domain six trajectories were observed. The rarely depressed and low-grade decreasing symptom groups were the least likely to have persistently low cognition. The symptom trajectory most strongly associated with persistently low functioning in each domain was not the higher-grade group but rather the low-grade increasing group in the case of attention and the moderate-grade trajectory in the other four domains. CONCLUSION Consistently higher-grade depressive symptoms are less strongly associated with poor cognitive functioning than with either moderate- or low-grade increasing depressive symptom trajectories, over time and across different domains. Examining both depression and cognition longitudinally allows heterogeneity of both to be addressed, revealing latent groups with potential diagnostic and prognostic implications.

Abstract
BACKGROUND The Euro-D depression scale consists of symptom clusters that may be differentially related to demographic and cognitive characteristics in older adults. This hypothesis needs further investigation and the role of measurement bias on substantive conclusions remains to be established. METHOD The study sample comprised 10,405 community-dwelling older adults from six Latin American countries. We applied a Multiple Indicators Multiple Causes (MIMIC) model for a concurrent investigation of measurement bias and of the association between Euro-D symptom clusters and background variables. RESULTS The factorial validity of Euro-D, with a two-dimensional structure--affective suffering and motivation disturbance, was consistently supported in all countries. Although complete measurement invariance could not be assumed across countries, measurement bias was minor. Both Euro-D factors were unrelated to age, but related to gender, as well as to impairment in memory and verbal fluency. Gender differences were larger for affective suffering than for motivation disturbance, whereas differences in verbal fluency impairment were more strongly related to motivation disturbance. LIMITATIONS Our analytic strategies could only examine invariance at the level of indicator thresholds. The generalisability of current findings needs to be examined in clinical populations. A wider set of cognitive tests is needed. We did not examine the compositional factors that could have accounted for the variation in Euro-D scores across countries, as this was beyond the aims of the paper. CONCLUSION The current study adds evidence for the construct validity of Euro-D and for the possible differential association of depression symptom-clusters with gender and verbal fluency in older adults. An understanding of the heterogeneity of late-life depression may carry clinical implications for the diagnosis and treatment of depression in old age.

Abstract
PURPOSE Numerous studies have examined the association of physical, behavioral and social factors with cognitive decline in older adults. Less attention has been placed on factors associated with long-term maintenance of intact cognition even into very old age. A greater understanding of those factors can inform the development of activities for maintaining cognitive strength. METHODS Using a sample from the Hispanic Established Populations for Epidemiologic Study of the Elderly, a population-based study of non-institutionalized Mexican Americans aged 65 and older from five Southwestern states (N = 2767), latent class mixture models were developed to identify subgroups of cognitive change over time. RESULTS Three distinct trajectories of cognitive change were identified and characterized as stable, slow decline and rapid decline. Compared to the rapid decline group, a higher proportion of the stable cognition group were women, had high school education, were married and attended church one or more times per week. Regular church attendance had a significant positive impact in the stable group (β = 0.64, p <0.01), the slow decline group (β = 0.84, p <0.001) and the rapid decline group (β = 2.50, p <0.001). Activity limitations had a consistently negative association with cognition in the stable, slow decline and rapid decline groups (β = -0.37, p <0.001; β = -0.85, p <0.001; and β = -1.58, p <0.001 respectively). CONCLUSION Substantial heterogeneity exists in rates of cognitive decline among older Mexican Americans. Interventions targeting cognitive maintenance may benefit from increased focus on factors associated with continued social engagement.

Abstract
Background This study examined associations between depressive symptoms and functional capacity, overall dependency in personal activities of daily living (ADLs), and dependency in individual ADL tasks, respectively, in people with a high mean age, large range of functional capacity, and wide spectrum of dependency in ADLs. Methods Cross-sectional data from three studies were used. A total of 392 individuals living in community and residential care facilities were included. Mean age was 86.2 years, 72% were women, 75% were dependent in ADLs, 42% had depression, and 39% had dementia. Depressive symptoms were assessed with the 15-item Geriatric Depression Scale (GDS-15), functional capacity with the Berg Balance Scale (BBS), and ADLs with the Barthel ADL Index. Multiple linear regression analyses with comprehensive adjustments were performed between GDS-15 and BBS, GDS-15 and Barthel ADL Index, and GDS-15 and each individual ADL task, separately. Results GDS-15 score was associated with BBS score (unstandardized b =−0.03, P=0.008), but not with Barthel ADL Index score (unstandardized b =−0.07, P=0.068). No significant interaction effects of sex, dementia, or living conditions were found in these associations. Among individual ADL tasks, dependency in transfer (unstandardized b =−1.03, P=0.007) and dressing (unstandardized b =−0.70, P=0.035) were associated with depressive symptoms. Conclusion Functional capacity seems to be independently associated with depressive symptoms in older people living in community and residential care facilities, whereas overall ADL performance may not be associated. Dependency in the individual ADL tasks of transfer and dressing appear to be independently associated with depressive symptoms and may be an important focus of future interdisciplinary multifactorial intervention studies.

Abstract
Depression is a common but worrying psychological disorder that adversely affects one's quality of life. It is more ominous to note that its incidence is increasing. On the other hand, screening and grading of depression is still a manual and time consuming process that might be biased. In addition, grades of depression are often determined in continuous ranges, e.g., 'mild to moderate' and 'moderate to severe' instead of making them more discrete as 'mild', 'moderate', and 'severe'. Grading as a continuous range is confusing to the doctors and thus affecting the management plan at large. Given this practical issue, the present paper attempts to differentiate depression grades more accurately using two neural net learning approaches-'supervised', i.e., classification with Back propagation neural network (BPNN) and Adaptive Network-based Fuzzy Inference System (ANFIS) classifiers, and 'unsupervised', i.e., 'clustering' technique with Self-organizing map (SOM), built in MATLAB 7. The reason for using the supervised and unsupervised learning approaches is that, supervised learning depends exclusively on domain knowledge. Supervision may induce biasness and subjectivities related to the decision-making. Finally, the performance of BPNN and ANFIS are compared and discussed. It was observed that ANFIS, being a hybrid system, performed much better compared to the BPNN classifier. On the other hand, SOM-based clustering technique is also found useful in constructing three distinct clusters. It also assists visualizing the multidimensional data clusters into 2-D.

Abstract
BACKGROUND Depression is a common experience affecting 121 million people around the world. In high income countries, depression is one of the most common psychiatric conditions among the elderly. Studies show that immigrants are particularly at risk for mental ill health. AIM This study investigates the self-reported mental health among two Iranian groups; one born and residing in Iran and one consisting of Iranian immigrants in Sweden, as well as native Swedes living in Sweden. The study also aims to explore and compare self-reported depressive symptoms among three groups. METHODS This study is based on a cross-sectional design measuring self-reported health with a study specific questionnaire. The programme SPSS V.17.0 was used for all statistical analyses. FINDINGS 1088 participants were approached (668 Iranians in Iran; 105 immigrated Iranians in Sweden; and 305 Swedes in Sweden). Factors effecting self-reported mental health was self-reported health, smoking, satisfaction with social life and also a sense of connection to ones cultural roots and traditions. Also demographic variables such as group belonging (Swedes vs. Iranians), sex and satisfaction with Income were shown to be important when performing the regression analysis. In the chi-square analysis the Iranian samples reported depressive symptoms to a larger extent than the Swedish group in all aspects of self-reported depressive symptoms. Self-reported depressive symptoms were reported to a greater extend in women compared to men. Our findings indicate that the Iranian populations living in both Tehran and Stockholm report depressive symptoms to an extent that merits concern. The findings indicate that Iranians living in Tehran and Iranians who have immigrated to Sweden require more attention regarding mental health care. Health care providers in both countries should be aware of the current state of mental health among Iranians in both Sweden and Iran.

The functional Val158Met polymorphism in catechol-O-methyltransferase (COMT) is associated with depression and motivation in men from a Swedish population-based study. J Affect Disord 2011; 129:158-66. [PMID: 20828831 DOI: 10.1016/j.jad.2010.08.009] [Citation(s) in RCA: 59] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/22/2010] [Revised: 08/05/2010] [Accepted: 08/09/2010] [Indexed: 11/29/2022]
Abstract
BACKGROUND Environmental risk factors together with genetic vulnerability create a complex background to develop depression. METHODS We investigated the associations between COMT Val(158)Met and depression in a Swedish population-based sample of 405 depressed individuals (major depression diagnosis, dysthymia or mixed anxiety depression defined according to DSM-IV) and 2,151 healthy controls. We also analyzed interaction between this genetic variation and some environmental risk factors for depression and the link between this polymorphism and the low motivational level and negative mood state found in depressed individuals. RESULTS Depressed individuals displayed a higher frequency of the Met/Met and Met/Val genotypes compared to controls (OR=1.49, CI(95%)=1.11-2.00, P=0.009). The association was found among men only (OR=2.26, CI(95%)=1.26-4.05, p=0.008). Regression analysis including some potential risk factors for depression, did further indicate that Met/Met and Met/Val were associated with depression in men (P=0.005). There was also an interaction between genotype and family childhood problems (RERI=0.876, CI(95%)=0.090-1.662 and AP=0.426, CI(95%)=0.030-0.821). Further, depressed men homozygous for the Val-allele, had a higher motivational level than depressed men with a Met-variant (P=0.02). LIMITATIONS The sample size of depressed individuals per group when stratifying cases according to gender and genotypes is considered a limitation. CONCLUSIONS The Met-variants of COMT Val(158)Met are risk variants for depression and low motivational level in depressed Swedish men, but not women. Individuals with this risk variant in combination with a problematic childhood, have an even higher risk to develop depression.

Abstract
BACKGROUND The association between depression and functional disability in late life remains unclear. This study aimed to explore the relationship between depressive symptoms and daily functioning through the mediation of cognitive abilities, measured by memory, reasoning, and speed of processing. METHODS The authors recruited 2,832 older adults (mean age = 73.6 years, standard deviation = 5.9) participating in the Advanced Cognitive Training for Independent and Vital Elderly Study. Structural equation modeling was applied to illustrate the relationship between depressive symptoms and everyday problem-solving ability through the mediation of cognitive abilities. RESULTS Depressive symptoms were associated with impaired everyday problem-solving ability directly and indirectly mediated through learning and memory, and reasoning. Although depressive symptoms were associated with speed of processing, speed of processing was not significantly related to everyday problem-solving ability. CONCLUSIONS This study conceptualizes the possible relationships between depressive symptoms and daily functioning with mediation of cognitive abilities and provides a feasible model for the prevention of functional impairment related to geriatric depressive symptoms.

Abstract
Less than half of older adults with depression achieve remission with antidepressant medications, and rates of remission are even poorer for those with comorbid conditions. Psychosocial interventions have been effective in treating geriatric depression, either alone or better yet, in combination with antidepressant medications. Traditional strategies for nonpharmacological treatment of late-life depression do not specifically address the co-occurring cognitive impairment and disability that is prevalent in this population. Newer therapies are recognizing the need to simultaneously direct treatment efforts in late-life depression towards the triad of depressive symptoms, cognitive dysfunction, and functional disability that is so often found in geriatric depression, and this comprehensive approach holds promise for improved treatment outcomes.

Abstract
OBJECTIVE To examine the association of personality with recurrence of depression in later life. METHOD A subsample of 91 subjects from the Longitudinal Aging Study Amsterdam (LASA; baseline sample size n=3107; aged > or = 55 years) depressed at baseline, who had recovered in the course of three years (first follow-up cycle) was identified. 41 (45%) respondents experienced a recurrence during the subsequent six years. The influences of personality and late life stress (demographic factors, health and social factors) on recurrence were investigated prospectively. RESULTS Recurrence of depression was associated with a high level of neuroticism and low level of mastery, residual depressive symptoms at time of recovery, female gender, pain complaints and feelings of loneliness. In multivariable analysis entering all predictors significant in single variable analysis, residual depressive symptoms and lack of mastery remained significantly associated with recurrence. CONCLUSION In predicting the recurrence of depression in later life, the direct effects of personality remain important and comparable in strength with other late life stressors related to recurrence.

Abstract
INTRODUCTION Major depressive disorder (MDD) is thought to negatively impact cognitive function; however, the relationship has not been well explored. OBJECTIVE This study examined the association between depression severity and global cognitive function and memory in subjects with severe, treatment-resistant MDD. METHODS We enrolled 66 subjects with Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosed unipolar MDD in a multicenter trial to assess the efficacy and neurocognitive effects of electroconvulsive therapy (ECT). We measured depression severity with the 24 item Hamilton Rating Scale for Depression (HRSD(24)). Neuropsychologic measures included the Mini Mental State Examination (MMSE), Rey Auditory Verbal Learning Test (RAVLT), and the Complex Figure Test (CFT). Correlational and regression analyses were conducted to explore associations between depression severity and cognitive function. RESULTS The mean age of the subjects was 53.6 years (SD=15.8), 65% were female, and mean HRSD(24) was 33.9 (SD=6.7). Mean demographic-corrected T-scores for each neurocognitive measure were in the average to borderline range, and HRSD(24) values were unrelated to performance on the MMSE, RAVLT immediate and delayed recall, and CFT immediate and delayed recall. CONCLUSION In this sample of severely depressed subjects referred for ECT, depression severity was unrelated to global cognitive function or memory. Future research should examine the interactions between other depressive characteristics and neurocognitive function.

Abstract
PURPOSE This study was conducted to analyze the factors that influence the life satisfaction of the elderly according to their cognitive impairment level. METHODS This study was conducted by dividing 3,012 elderly residents of a regional community into three groups based on the scores of the Korean version of the Mini-Mental State Examination: a normal group without any cognitive impairment, a suspicious group with a mild level of cognitive impairment, and a high risk group with a high level of cognitive impairment. Researchers made phone calls, house calls, and personal visits to health centers and shelters for the elderly to gather the information required for this study. RESULTS The results of this study revealed that social relationships, depression, and activities of daily living had a significant impact on life satisfaction for the normal group, while social relationships and depression had a high impact on life satisfaction for the suspicious group, and social relationships had high impact on the life satisfaction of the high risk group. CONCLUSION Based on the results of this study, we suggest that programs that promote development of the social relationship networks of the elderly should be established to promote their life satisfaction.

Abstract
OBJECTIVE The primary purpose of this study was to investigate the differences in the serum brain-derived neurotrophic factor (BDNF) level between elderly Korean people over 65 years with and without dementia. METHODS 171 individuals over 65 years were enrolled in this study. Screening for cognitive impairments was carried out using the Mini-Mental Status Examination-Korean version (MMSE-KC). One hundred thirty-two subjects scored below 1.5 standard deviations (SD) of the mean MMSE-KC score, and these were evaluated using the Consortium to Establish a Registry for Alzheimer's Disease, Korean version (CERAD-K) and the Geriatric Depression Scale (GDS). The Clinical Dementia Rating Scale (CDRS) and the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) diagnostic criteria were used for further evaluation. Subjects with a CDRS score of 1 or higher were classified as having Alzheimer's disease (AD), and subjects with a CDRS score of 0.5 were classified as having a mild cognitive impairment (MCI). Subjects with a CDRS score of 0 were classified as having aging-associated cognitive decline (AACD). Serum BDNF levels were analyzed using the enzyme-linked immunosorbent assay (ELISA) method. RESULTS The serum BDNF levels were significantly lower in the subjects with MCI and AD compared with the healthy controls (p<0.01). A significant correlation was found between the total MMSE-KC score and serum BDNF level (r=0.295; p<0.01). However, no significant correlation was observed between the severity of MMSE-KC and the total GDS score. A significant difference was found in the total score of GDS between the AACD group and subjects with AD (p<0.05). CONCLUSION This study suggested that BDNF might be involved in the pathophysiology of cognitive decline in elderly people.

Abstract
OBJECTIVES The aim of this study was to investigate factors associated with depression among men and women aged 85 and over. METHOD A population-based study was undertaken in northern Sweden. Out of 527 eligible participants, aged 85, 90 or > or = 95, 363 were evaluated for depression. Data were collected from structured interviews, assessments and medical charts and from relatives and caregivers. Depression was screened for using the Geriatric Depression Scale-15 and further assessed using the Montgomerysberg Depression Rating Scale (MADRS). RESULTS A higher proportion of women were diagnosed with depression (33% vs. 18.6%, p = 0.006). In both men and women experienced loneliness (OR 3.4 vs. 7.0) and not going outside independently (OR 2.6 vs. 26.0) were associated with depression in the final regression model. Depression among men was also independently associated with loss of a child/children during the preceeding ten years (OR 30.0). CONCLUSION Depression was more common among women than among men. Experienced loneliness and not going outside independently seem to be closely related to depression in both men and women. Loss of a child seems to be the most important factor among men.

Abstract
The purpose of this randomized, controlled trial was to test the efficacy of a community-based intervention, the Life Story Workshop, on depressive symptoms, operationalized as depression subscale scores on the Brief Symptom Inventory 18, in adults age 60 and older. Thirty-three men and women were randomly assigned to one of two groups: an intervention group that attended 2-hour workshops once a week for 10 weeks or a wait-list control group. The intervention provided an opportunity for older participants to reflect on, write, and share stories about their lived and current lives. The depression subscale of the Brief Symptom Inventory 18 was administered before and after the workshops. Mean depression scores were compared using Welch's t test. A significant improvement was measured for the intervention group compared with the control group (p = .03). This research supports the Life Story Workshop as an effective intervention for improving depressive symptoms in older adults.

Abstract
OBJECTIVES The objectives were to investigate the predictive value of hierarchy levels and sum score of disability and change in disability on depressive symptoms. METHOD Longitudinal data of 723 men age 70 and older from the Finland, Italy, and the Netherlands Elderly Study were collected in 1990 and 1995. Self-reported disability was based on three disability domains (instrumental activities, mobility, and basic activities) and depressive symptoms on the Zung questionnaire. RESULTS Severity levels of disability were positively associated with depressive symptoms. Men with no disability scored 5 to 17 points lower (p < .01) on depressive symptoms than did those with disability in all domains. Among men with mild disability, those who had worsening of disability status in the preceding 5 years scored 5 points higher (p = .004) on depressive symptoms than did men who improved. DISCUSSION Hierarchic severity levels, sum score of disability, and preceding changes in disability status are risk factors for depressive symptoms.

Abstract
OBJECTIVES To investigate the development of mobility status during the second year after stroke in patients who had had inpatient rehabilitation, and to evaluate risk factors for mobility decline. DESIGN Evaluation of change in Rivermead Mobility Index (RMI) score over the second year after stroke in an inception cohort of first-ever stroke patients eligible for inpatient rehabilitation. Logistic regression techniques were used to predict decline. Independent variables were measured with standardized instruments 1 year after stroke. SETTING Home or institution, after discharge from rehabilitation center. PARTICIPANTS Patients (N=148) with single first-ever stroke (supratentorial), age more than 18 years. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURES Decline of 2 or more points on the RMI and the percentages and odds ratios (ORs) for decline. RESULTS The mean RMI score did not significantly change over time. Mobility declined in 12% of the patients. Mobility decline was found more often in patients with depression (25%) than without (7%), with right-sided weakness (17% vs 8%), with ischemic stroke (13% vs 8%), with aphasia (22% vs 11%), with cognitive dysfunction (17% vs 11%), with comorbidity interfering with locomotion (25% vs 12%), with poor social functioning (15% vs 10%), and with mobility disability (16% vs 8%). Statistical significance was found only for depression (OR=4.2; 95% confidence interval, 1.3-13.2). CONCLUSIONS Most patients maintained the level of mobility they achieved during inpatient rehabilitation over the second year after stroke. Only 12% had a decline in mobility, and depression was the only statistically significant predictor for decline.

Abstract
Although Alzheimer's disease has long been considered mainly a cognitive disorder, behavioral and psychological symptoms are present from its onset and at all the stages of the disease in most patients. They must be identified from the beginning because they orient the diagnosis. They include affective and emotional disorders, delusions and hallucinations, disorders of instinctual behavior and behavioral problems. The best tool for assessing them is the Neuropsychiatric Inventory (NPI). They are generally related to neurobiological aspects of the disease but may, especially when acute, have multiple etiologies: somatic, iatrogenic, psychological and environmental. They condition the course of the disease. As a source of suffering and reduced quality of the life and as the primary cause of distress for the caregivers and hence of hospitalization and institutionalization, they increase the costs of care. The challenge today is to learn more about them and thus improve their treatment and especially their prevention.

Abstract
Depression is the most common mental disorder among older adults in the United States and one of the most disabling conditions worldwide. Chronic conditions and related functional limitations are associated with late-life depression, but assessment of depression is complicated by the absence of measures that capture the range of depressive emotions older adults may express. This descriptive, correlational study of 314 older adults with chronic conditions examined three measures to assess depressive symptoms: the Center for Epidemiological Studies Depression Scale (CES-D), the short form of the Center for Epidemiological Studies Depression Scale (CES-D-10), and an Emotional Symptom Checklist (ESC). The measures were correlated with each other and with a number of chronic conditions and functional impairments. Men and women scored similarly on all measures, though correlations between depressive symptoms and negative emotions were stronger for men. About 12% of the older adults exceeded the CES-D criteria for severe depressive symptoms, with the greatest percentage among those aged 75 to 84. The most frequently reported negative emotions were sadness (by women and elders through age 84) and loneliness (by men and elders age 85 and over). The findings suggest the need for multiple assessment strategies to identify older adults at risk for late-life depression.

Abstract
Somatic symptoms are known to be a prominent characteristic in patients with depression. The aim of the present study was to investigate the major somatic and psychiatric symptoms associated with depression in each sex. Patients with a DSM-IV diagnosis of depressive disorders (n=335) and comparison patients without depression (n=423) among new outpatients in an urban hospital medical setting were eligible for study. The relationship between the the most distressing subjective symptoms at first visit, confirmed by the patient's description on a health questionnaire and the admitting physician's interview, and depression was investigated in each sex. Most (73.5%) of the complaints in patients with depression were somatic. In a simple logistic regression analysis, diarrhea, excessive sweating and psychomotor retardation in men and headache, depressed mood and grief in women were associated with depression. In multiple logistic regression analysis, diarrhea, excessive sweating and weight loss in men, and headache, dysesthesia and grief in women, as well as sleep disturbance, loss of appetite, general fatigue loss on interest and agitation in both sexes, were significantly associated with depression. Fever in men was also associated with depression by Fisher's exact test.

Abstract
This study examined the associations among self-efficacy, health locus of control, and psychological distress in 159 elderly Chinese women who had chronic physical illnesses. The present findings did not support the dual health control hypothesis that specifies the balance between internal and external health control beliefs is related to a low level of psychological distress. Correlation results showed that internal health locus of control was linked to general self-efficacy. Results from hierarchical regression analysis indicated that health control beliefs did not interact with general self-efficacy; instead, these two variables each exerted their main effects on participants' negative mental health status. It was found that psychological distress was best predicted by a low level of general self-efficacy as well as a high level of external health locus of control. Internal health control beliefs did not contribute to the prediction of distress. Implications and limitations of this study were also discussed.

Abstract
This research shows the utility of systematic data-gathering from older people and of a statistical analysis procedure for interpreting the data. Four cases of institutionalized older people are presented, and their scores of depressive symptomatology over a period of one to two years is analyzed. Time-series analysis showed a significant positive trend of depression symptomatology in two of the cases, perhaps too subtle for detection in routine clinical check-up, but statistically verifiable. In one of these cases, none of the factors of the scale stands out, despite the fact that the general index shows a statistically significant change over the 36 observations made, so that the results obtained are related to the syndrome of depletion or exhaustion. In the second of the cases, we detect a significant change in the depressive mood factor, which may indicate a subclinical depressive form in its initial stages. Continuous registers can reveal valuable information about situations and progress in the evolution of an older person's mood, with regard to natural development, the prelude to a mood disorder, or follow-up in clinical cases.

Abstract
The current longitudinal study analyzes the natural course of depressive symptoms in patients with Alzheimer disease (AD). The goals were to identify the clinical and sociodemographic variables related to depressive symptoms, to assess the effect of depressive symptoms on the course of cognitive and functional impairment and on associated neuropsychiatric disorders, and to identify which factors are associated with remission, persistence, and emergence of depressive symptoms at 12 months. A sample of 150 patients with mild or moderate severity was assessed at baseline and at 12 months using the neuropsychologic battery Cambridge Cognitive Examination. The Neuropsychiatric Inventory and Rapid Disability Rating Scale were administered to the caregiver. Prevalence, persistence, and emergence of depressive symptoms at baseline were 51%, 55%, and 20%, respectively. Remission of depressive symptoms at 12 months leads to a decreased frequency of other noncognitive disorders and to a slight improvement in the assessment of global function. The presence of depressive symptoms does not affect the course of cognitive impairment at 12 months, and a psychiatric history of the patient and the number of depressive symptoms at baseline are risk factors for the emergence and persistence of depressive symptoms at 12 months.

Abstract
INTRODUCTION Depression is common in Alzheimer's disease (AD). The symptomatology of depression in dementia may differ from depression alone. Consequently, the reports on lifetime depressive symptoms were compared in AD patients and age-matched non-demented participants. METHODS Seventy-six AD patients, 109 elderly from the general population and their 189 siblings were examined using the Composite International Diagnostic Interview (CIDI). The presence of individual lifetime depressive symptoms was compared between 76 AD patients, 29 AD patients with comorbid depression, and different control groups using chi(2) statistics and logistic regression analysis. RESULTS Lifetime depressive symptoms were significantly more frequent in 76 AD patients than in 109 age-matched elderly from the general population. These 76 AD patients complained more about thinking and concentration disturbances, and less about depressed mood or appetite disturbance than the 298 non-demented participants matched for the lifetime presence of major depression (MD). In agreement, the 29 patients comorbid for lifetime diagnoses of AD and MD reported less about depressed mood than the 114 age-matched elderly with MD only. Feelings of worthlessness and suicidal ideas were related to the severity of cognitive decline. CONCLUSION AD influences the reports on lifetime depressive symptoms. This may be caused by additional neurodegeneration, by an overlap of symptoms of depression and dementia or by an altered perception of mood disturbances in AD. Further studies should investigate these alternatives.

Abstract
Late life depression principally affects individuals with other medical and psychosocial problems, including cognitive dysfunction, disability, medical illnesses, and social isolation. The clinical associations of late life depression have guided the development of hypotheses on mechanisms predisposing, initiating, and perpetuating specific mood syndromes. Comorbidity studies have demonstrated a relationship between frontostriatal impairment and late life depression. Further research has the potential to identify dysfunctions of specific frontostriatal systems critical for antidepressant response and to lead to novel pharmacological treatments and targeted psychosocial interventions. The reciprocal interactions of depression with disability, medical illnesses, treatment adherence, and other psychosocial factors complicate the care of depressed older adults. Growing knowledge of the clinical complexity introduced by the comorbidity of late life depression can guide the development of comprehensive treatment models. Targeting the interacting clinical characteristics associated with poor outcomes has the potential to interrupt the spiral of deterioration of depressed elderly patients. Treatment models can be most effective if they focus on amelioration of depressive symptoms, but also on treatment adherence, prevention of relapse and recurrence, reduction of medical burden and disability, and improvement of the quality of life of patients and their families.

Abstract
OBJECTIVE The authors report results from a 7-year prospective study of depression and mortality in 2,558 Medicare recipients age 65 and older. METHODS This report is based on a secondary data analysis of a randomized controlled trial that evaluated the cost-effectiveness of preventive services for older enrollees in an HMO. RESULTS Subjects with mild-to-moderate depression at baseline did not have an increased risk of mortality compared with those without significant depression. The 3% of older adults with the most severe depressive syndromes, however, had significant increases in mortality, even after adjusting for demographics, health risk behaviors, and chronic medical disorders. CONCLUSION The increase in mortality in this group of older adults was comparable to that in participants with chronic medical disorders such as emphysema or heart disease.

Abstract
OBJECTIVES Women suffer more frequently from major depression and depressive symptoms than men. The somatic and the atypical subtype of depression seem to be more prevalent in women. However, few studies investigated gender differences of depressive symptoms in the elderly. These gender differences in the elderly will be investigated in the present study. METHODS In the course of a family study 236 subjects with a lifetime diagnosis of major depression aged > 50 years and 357 control subjects from the general population matched for age and gender were questioned using the Composite International Diagnostic Interview (CIDI). Chi-square tests were used to compare the individual depressive symptoms between men and women and logistic regression analyses were performed to account for the subjects' age, cognitive performance, family and employment status. RESULTS Women in the general population suffered from more depressive symptoms than men and had more appetite disturbance and joylessness. These gender differences could be entirely explained by gender differences in the family and the employment status. Men and women with a major depressive disorder presented with a distinct profile of symptoms that could not be explained by psychosocial factors: elderly depressed women presented with more appetite disturbances and elderly depressed men with more agitation. CONCLUSION Major depression in the elderly presents with partially different symptoms in men and women. The results suggest that the gender differences in the symptoms of major depression in the elderly reflect gender differences in the perception and the expression of depressive syndromes.

Abstract
Apathy, or loss of motivation, is arguably the most common change in behavior in Alzheimer's disease (AD) but is underrecognized. Apathy represents a form of executive cognitive dysfunction. Patients with apathy suffer from decreased daily function and specific cognitive deficits and rely on families to provide more care, which results in increased stress for families. Apathy is one of the primary syndromes associated with frontal and subcortical pathology, and apathy in AD appears to have multiple neuroanatomical correlates that implicate components of frontal subcortical networks. Despite the profound effects of this common syndrome, only a few instruments have been designed to specifically assess apathy, and these instruments have not been directly compared. Assessment of apathy in AD requires clinicians to distinguish loss of motivation from loss of ability due to cognitive decline. Although apathy may be misdiagnosed as depression because of an overlap in symptoms, current research has shown apathy to be a discrete syndrome. Distinguishing apathy from depression has important treatment implications, because these disorders respond to different interventions. Further research is required to clarify the specific neuroanatomical and neuropsychological correlates of apathy and to determine how correct diagnosis and treatment of apathy may improve patient functioning and ease caregiver burden.

Abstract
Normal aging of the brain affects the basal ganglia-thalamocortical circuits. These circuits are implicated in several neuropsychiatric disorders. Normal aging may therefore influence the symptomatology of psychiatric disorders in the elderly. We investigated motivational behavior that is associated with the function of these circuits, such as apathy, anhedonia, and psychomotor retardation in healthy elderly subjects and psychiatric inpatients (age > or = 60 yr). Apathy, anhedonia, and psychomotor retardation were assessed with the Apathy Evaluation Scale, the Snaith-Hamilton Pleasure Scale, and the Widlöcher Retardation Rating Scale. Other measurements included the Comprehensive Psychopathological Rating Scale, the Mini-Mental State Examination, and the assessment of vascular risk factors. We found some evidence for age-related changes in motivational behavior. In the healthy elderly group (n = 64), increasing age was associated with anhedonia, and in the patient group (n = 62), increasing age was associated with psychomotor retardation. Motivational disturbances could be the effect of an interaction between brain aging and the neuropathology of psychiatric disorders in the elderly.

Abstract
OBJECTIVES This prospectively designed longitudinal study assesses prevalence, incidence and prognosis of depressive symptoms among cognitively normal elderly volunteers compared with patients with mild cognitive impairment (MCI), dementia of Alzheimer type (DAT), and vascular dementia (VAD). Possible relationships between depressive symptoms, cognitive performance, disease types, and effects of antidepressant treatment were analyzed. METHODS Two hundred and ninety four subjects exhibiting different levels of cognitive performance were admitted to this study. Demographics, cardiovascular and neurodegenerative risk factors, together with measures of neuropsychological test performance, were obtained at sequential visits. Depressive symptoms were selectively treated with antidepressant medications. RESULTS One hundred and forty six subjects with normal cognition, 19 subjects with MCI, 42 patients with DAT, and 32 patients with VAD were followed for a mean of 3.5 years. With the passage of time, there were trends showing prevalence of depressive symptoms to decrease among DAT and to increase among VAD patients. VAD patients exhibited the highest incidences of new-onset depressive symptoms, followed in incidence by DAT and MCI groups. Depressive symptoms among VAD and MCI patients were more persistent and refractory to antidepressant medications than for DAT patients. Trends suggested that antidepressant treatment might benefit MCI and VAD subjects more than DAT patients. Motivationally related depressive symptoms accounted for major components of elevated Hamilton depression rating scale scores. CONCLUSIONS Depressive symptoms among DAT patients have higher rates of spontaneous resolution, without requiring intensive drug treatment, than among VAD patients in whom depressive symptoms are more persistent and refractory to drug treatment. Early depressive symptoms among subjects with MCI may represent a preclinical sign and should be considered as a risk factor for impending DAT or VAD among the elderly.

Abstract
OBJECTIVES The present cross-sectional study analyzed the prevalence and severity of depressive symptoms among patients with Alzheimer's disease (DAT), vascular dementia (VAD), and among the cognitively normal elderly. Putative risk factors contributing to depression were likewise evaluated. METHODS Seventy-six DAT patients, 51 VAD patients, and 121 cognitively normal subjects were admitted to the study. Questionnaires concerning demography and their vascular and familial risk factors together with results of neuropsychological testing by combined Mini-Mental Status Examinations (MMSE), Cognitive Capacity Screening Examinations (CCSE), and Hamilton Depression Rating Scales (HDRS) were obtained so that resulting data would be statistically analyzed. RESULTS Prevalence of depressive symptoms among VAD, DAT, and cognitively normal elderly were 31.4%, 19.9%, and 13.2%, respectively. 25.5% of VAD and 13.2% of DAT patients had depression of mild to moderate degrees. Regression analysis revealed that diagnosis of VAD and DAT, heart disease, and past history of depression was significantly associated with high HDRS scores. There was no correlation between degree of depression and severity of cognitive impairments. CONCLUSION Mild to moderate depression is a common comorbidity with organic dementia, especially VAD, but associated depression is independent of severity of cognitive impairments.

Abstract
The effects of functional decline upon social networks, life satisfaction, and depression were observed and statistically tested in a longitudinal prospective design. Subjects were 692 Japanese elderly, aged sixty-five years or older, with high functional capacity at baseline. During a two-year period of follow-up, 12.3 percent of the subjects experienced functional decline. Repeated-measure analyses of covariance with statistical tests for simple main effects revealed that changes in the criterion variables significantly differed along with changes in functional health status when the effects of age, gender, and socioeconomic status were controlled. The subjects who experienced functional decline showed a larger decrease in the number of relatives, friends, and neighbors having frequent contacts, a larger decline in life satisfaction, and a larger increase in depression than those without functional decline. The results seem to confirm further the importance of functional health status as a prerequisite for higher quality of life in old age.

Abstract
OBJECTIVE The main aim of this study is to add new evidence on the descriptive epidemiology of depressed mood, and to investigate suspected determinants for depressed mood in adulthood. METHODS The data are from a continuing survey of a nationally representative sample of adult household residents in the United States, conducted in 1995 and 1996, totaling 26,883 respondents. Multiple logistic regression procedures yielded estimated associations. RESULTS We found that an estimated 1.9% of adult females and 1.0% of adult males experience a spell of sustained depressed mood during a span of approximately 2 weeks duration (i.e. point prevalence). For most of these cases, this is not the first spell. Among women, the smoothed curve for the prevalence estimates shows a peak in the youngest age stratum and decreases across age strata before 60 years, and has a slight secondary peak thereafter. In contrast, for males, the prevalence estimates of depression show no peak in the older age strata. Evidence from logistic regression analyses supports the inference of this later life peak in frequency of depressed mood among women. These new findings add to a growing body of epidemiological evidence on age and depression, and provoke new questions about the possibly etiological relationships involving social structural characteristics of local neighborhoods in combination with individual-level risk factors that have received primary attention in recent psychiatric epidemiology. CONCLUSIONS These findings point to the need for further etiological research, including studies of relationships between social structural characteristics of local neighborhoods and the occurrence of spells of depressed mood, as well as clinical implications for depression mood in late life.

The influence of cardiovascular signs (CVS) on cognitive performance was examined in 227 older adults not suffering from dementia between 75 and 96 years of age who were sampled from the community. Participants received a comprehensive physical examination that included specific evaluation of current CVS, including dyspnea, cardiac murmur, and edema in lower limbs. They were administered tests of digit span, episodic recall and recognition, verbal fluency, and visuospatial skill. CVS were found to predict performance on tests of episodic memory and visuospatial skill, after the effects of age, education, gender, relevant drug use, and mood symptoms were controlled for. Although CVS accounted for relatively little general performance variation, the findings are relevant to the understanding of normal variation in late-life cognitive performance. Finally, CVS increased with age and accounted for a sizable proportion of the age-related cognitive variation.

Abstract
OBJECTIVE To examine treatment for depression among older adults in a large staff model health maintenance organization (HMO). DESIGN A 4-year prospective cohort study (1989-1993). SETTING Four primary care clinics of a large staff model HMO in Seattle, Washington. PATIENTS A total of 2558 Medicare enrollees aged 65 and older. MAIN OUTCOME MEASURES Treatment of depression was defined as primary care visits resulting in depression diagnoses, use of antidepressant medications, or specialty mental health services. MAIN RESULTS The older adults in our sample had low rates of treatment for depression, ranging from 4 to 7% in the entire sample and from 12 to 25% among those with probable depressive disorders. Predictors of treatment included female gender, severity, and persistence of depressive symptoms, and severity of comorbid medical illness. Even when patients were treated for depression, the intensity of treatment was very low. Overall likelihood of treatment for depression increased somewhat from 1989 to 1993, but among those treated, the rate of adequate antidepressant use remained below 30%. CONCLUSIONS There is still considerable need to improve care for older adults with depression in primary care.

Abstract
This review focuses on recent literature concerning dysthymia in the elderly population. Epidemiological data and clinical picture, diagnostic and therapeutic issues are evaluated and discussed. Although depressive syndromes are common in older patients, prevalence rates of dysthymia in the elderly are lower than in younger adults. This finding may be the consequence of the diagnostic criteria provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM) which are not specific for older adults. Other factors that complicate making diagnoses of dysthymia in older individuals are comorbid general conditions, cognitive deterioration and disorders, and frequent adverse life events (e.g. bereavement). The effects of these factors should be better defined to clarify whether elderly dysthymia is underestimated and if modified diagnostic criteria should be provided. A few researchers have identified a series of clinical features that are clearly different in the elderly and in young adult patients with dysthymia. These features are particularly related to the late onset and to the peculiar comorbidity of this disorder and suggest that dysthymia is a different disorder in the elderly. Drug treatment of depressive conditions in the elderly is currently based on new antidepressants [selective serotonin (5-hydroxytryptamine; 5-HT) reuptake inhibitors, norepinephrine (noradrenaline) reuptake inhibitors, benzamides]. These agents have an improved adverse effect profile compared with some of the older agents. Moreover, very few systematic studies have been performed using these drugs in samples of older patients with dysthymia and available data do not allow conclusions on drug choice and dosage. Besides, no specific data are available concerning the psychotherapy of dysthymia in this age group. All these topics need to be further investigated in studies comparing the elderly with control groups of younger patients with dysthymia.
