Abstract
OBJECTIVES We compared the prevalence of subtypes of depression in patients with Alzheimer's disease (AD), vascular dementia (VaD), and unspecified dementia (UD). METHODS Using the Integrated Healthcare Information Services database, we conducted an analysis of subtypes of depression (major depressive disorder, depressive disorder not otherwise specified, dysthymic disorder; depressive psychosis, and adjustment disorder depressive) among patients with AD, VaD, and UD. Six thousand four hundred and forty patients aged 60 years or older with dementia (2947 with AD, 725 with VaD, and 2768 with UD) were identified from January 1 to December 31, 2001. Both subtypes of depression and dementia subgroups were diagnosed using criteria from the International Classification of Diseases, 9th version. RESULTS The overall prevalence of depressive disorders was 27.41%. The prevalence of depressive disorders was significantly higher in VaD (44.14%) and UD (32.48%) patients compared with AD (18.53%, P < .0001) patients. The AD patients had the lowest prevalence of all subtypes of depression. The VaD patients, compared with both AD and UD (P < .005), had a significantly higher prevalence of: 1) depressive disorder not otherwise specified, 2) major depressive disorder, and 3) dysthymic disorder. Adjustment disorder with depressive symptoms was more common in the UD subgroup, whereas the rate of depressive psychosis was similar in all dementia subgroups CONCLUSIONS This study supports the view that depressive disorders are more prevalent in VaD compared with UD and AD, and provides indicators to the clinician for further evaluation of depression in dementia subgroups.

Abstract
OBJECTIVE This paper examines possible mechanisms that may explain the bi-directional relationship between vascular disease and depression. DESIGN A literature review was carried out using Medline from 1996 to 2007, using relevant key words including vascular depression, and supplemented by key references to earlier work. RESULTS Several mechanisms were considered including: autonomic dysfunction, platelet activation, hypothalamic pituitary axis activation, endothelial dysfunction, cytokines, omega 3 fatty acids, genetics, homocysteine and effects of treatment. CONCLUSIONS The relationship between vascular disease and depression cannot solely be explained by current established risk factors or the effects of treatment for depression. Other mechanisms must apply, and there is some evidence for common genetic factors. Promising future lines of investigation include homocysteine, cytokines and endothelial dysfunction. More longitudinal studies combined with measurements of these biomarkers are needed.

Abstract
Until recently, little attention has been paid to anxiety symptoms in dementia. However, anxiety is common in this population, and associated with poor outcome and quality of life. The current review examines the existing literature around three major themes: the definition of anxiety in dementia, the properties of available instruments for assessment, and the clinical characteristics of anxiety in this population. Defining anxiety in individuals with dementia is complicated by the overlap between symptoms of anxiety, depression and dementia, and by the influence of the source of information. Several instruments are available to assess anxiety in this population, including general neuropsychiatric instruments and two scales designed specifically for this purpose. The reliability of these instruments is acceptable, but their validity has not been sufficiently examined, and they may discriminate poorly between anxiety and depression. Anxiety may be higher in vascular dementia than in Alzheimer's Disease, and it decreases in the severe stages of dementia. It is associated with poor quality of life and behavioral disturbances, even after controlling for depression. Little is known, however, about its social and environmental correlates. Limitations of the existing literature and key directions for future research are discussed.

Abstract
BACKGROUND Despite the relative neglect of anxiety in older adults, the growing literature on its prevalence suggests that anxiety is highly prevalent and associated with considerable distress and morbidity in this age group. This review provides a comprehensive overview of this literature and discusses some unresolved controversies in the field. METHODS A systematic search of articles published from 1980-2007 was performed. Articles were included for review if they reported the prevalence of anxiety symptoms, anxiety disorder or specified anxiety disorders in adults aged >60 in either community or clinical settings. RESULTS The prevalence of anxiety in community samples ranges from 1.2% to 15%, and in clinical settings from 1% to 28%. The prevalence of anxiety symptoms is much higher, ranging from 15% to 52.3% in community samples, and 15% to 56% in clinical samples. These discrepancies are partly attributable to the conceptual and methodological inconsistencies that characterise this literature. Generalised Anxiety Disorder is the commonest anxiety disorder in older adults. LIMITATIONS The methodologies used in the studies are so variable as to make comparisons difficult. CONCLUSIONS Although anxiety disorder, particularly Generalised Anxiety Disorder is common, issues in relation to comorbidity and the nature of anxiety in old age remain unresolved. This hampers the design of intervention programmes, and highlights the need for further research with a primary focus on anxiety.

Abstract
OBJECTIVE i) to describe the neuropsychiatric profile of elderly subjects with dementia by comparing vascular (VaD) and degenerative dementias, i.e. dementia with Lewy bodies (DLB) and Alzheimer's disease (AD); ii) to assess whether the severity and type of dementia are associated with clinically relevant neuropsychiatric symptoms (CR-NPS). METHOD One hundred and thirty-one out-patients with VaD, 100 with DLB and 690 with AD were studied. NPS were evaluated by the neuropsychiatric inventory (NPI). RESULTS Vascular dementia had lower total and domain-specific NPI scores and a lower frequency of CR-NPS than AD and DLB, for which frequency of CR-NPS increased significantly with disease severity, particularly in AD. Logistic regression analysis showed that a higher CDR score and a diagnosis of degenerative dementia were independently associated with CR-NPS. CONCLUSION Vascular dementia is associated less with CR-NPS than AD and DLB. Frequency of CR-NPS increases with disease severity in AD and, to a lesser extent, in DLB.

Abstract
OBJECTIVE To examine, in an exploratory analysis, the association between vascular conditions and the occurrence of neuropsychiatric symptoms (NPS) in a population-based sample of incident Alzheimer's disease (AD). METHODS The sample consisted of 254 participants, identified through two waves of assessment. NPS were assessed using the Neuropsychiatric Inventory. Prior to the onset of AD, data regarding a history of stroke, hypertension, hyperlipidemia, heart attack or coronary artery bypass graft (CABG), and diabetes were recorded. Logistic regression procedures were used to examine the relationship of each vascular condition to individual neuropsychiatric symptoms. Covariates considered were age, gender, education, APOE genotype, dementia severity, and overall health status. RESULTS One or more NPS were observed in 51% of participants. Depression was most common (25.8%), followed by apathy (18.6%), and irritability (17.7%). Least common were elation (0.8%), hallucinations (5.6%), and disinhibition (6.0%). Stroke prior to the onset of AD was associated with increased risk of delusions (OR = 4.76, p = 0.02), depression (OR = 3.87, p = 0.03), and apathy (OR = 4.48, p = 0.02). Hypertension was associated with increased risk of delusions (OR = 2.34, p = 0.02), anxiety (OR = 4.10, p = 0.002), and agitation/aggression (OR = 2.82, p = 0.01). No associations were observed between NPS and diabetes, hyperlipidemia, heart attack or CABG, or overall health. CONCLUSIONS Results suggest that a history of stroke and hypertension increase the risk of specific NPS in patients with AD. These conditions may disrupt neural circuitry in brain areas involved in NPS. Findings may provide an avenue for reduction in occurrence of NPS through the treatment or prevention of vascular risk conditions.

Abstract
BACKGROUND Determination of the prevalence of neuropsychiatric symptoms in elderly patients with dementia in Mungialde. METHODS 108 subjects with dementia, who participated in a door-to-door epidemiological study, were included. The 12-item Spanish version of the Neuropsychiatric Inventory was used to evaluate these symptoms. RESULTS The prevalence of at least 1 neuropsychiatric symptom was found to be 76.90% for all dementia types, 73.50% in patients with Alzheimer's disease (AD), 80% for the Parkinson-Lewy body dementia complex (PLBD), 78.60% for vascular dementia (VD) and 100% for frontotemporal dementia (FTD). Apathy was found to be the most prevalent symptom for all dementia types and in patients with AD (53.70 and 54.30%, respectively). The next most prevalent symptoms were anxiety, depression and sleep disturbances (35.20, 32.40 and 30.60%) for all dementia types, and anxiety and depression (32.10 and 30.90%) in patients with AD. The most prevalent symptoms in patients with PLBD were apathy, appetite changes, sleep disturbances and agitation (50% each); in patients with VD they were apathy, depression and anxiety (42.90% each), and in patients with FTD they were apathy, anxiety and aberrant motor activity (100% each). CONCLUSIONS Neuropsychiatric symptoms were found to be prevalent in patients with dementia, irrespective of dementia type.

Abstract
BACKGROUND/AIMS Anxiety and depression are common inpatients with cognitive decline and Alzheimer's disease (AD), and recognition and treatment of these symptoms can improve their quality of life. The present study investigates anxiety and depression in different phases of cognitive decline. METHODS The sample consisted of five groups of elderly people in different phases of cognitive decline; four from a community-based sample (Longitudinal Aging Study Amsterdam), and one group of elderly people diagnosed with AD. ANOVAs were performed to investigate group differences in the severity and prevalence of anxiety and depression, and comorbid anxiety and depressive symptoms. RESULTS The prevalence rates of anxiety, comorbid anxiety and depressive symptoms and depressive symptoms follow a pattern of an increasing prevalence as cognitive performance declines and a decrease in the prevalence when cognitive functioning is severely impaired. AD patients report fewest anxiety symptoms. CONCLUSION We found that the prevalence of anxiety symptoms, depressive symptoms and comorbid anxiety and depressive symptoms seems to increase in the early phase of cognitive decline, and decreases as cognitive functioning further declines. Elderly diagnosed with AD report less anxiety as expected, probably due to lack of insight caused by AD.

Abstract
BACKGROUND Distinguishing between patients with frontotemporal lobar dementia (FTLD) and other dementing illnesses remains a difficult task for many clinicians. In this study, we aimed to provide further evidence for the construct validity of the frontal behavioural inventory (FBI) and assess its utility in differentiating FTLD patients from other groups using data from the Canadian Collaborative Cohort of Related Dementias (ACCORD) study. METHOD Baseline scores on the FBI and neuropsychiatric inventory (NPI) were compared among several clinical groups (n = 177). RESULTS The FBI discriminated a higher percentage of FTLD patients (>75% correct classification) from Alzheimer's disease and other groups compared to the NPI (54.2%). CONCLUSION This study provides good evidence for convergent validity between the FBI and NPI (r = 0.72), indicating that both measures capture similar psychopathology in this nationwide cohort.

Abstract
BACKGROUND The objective of this review is to provide information for clinicians regarding current research and opinions on the association of depression to conditions of cognitive impairment and dementia. We also intend to integrate this current research and thinking into strategies for the assessment and treatment of depression in the context of cognitive impairment. REVIEW SUMMARY Depression is highly prevalent in mild cognitive impairment and most dementias. It may be a risk factor for the subsequent development of dementia and in some conditions may be a prodromal symptom. It is important to detect and effectively treat depression because the comorbidity of depression and cognitive impairment is associated with greater cognitive and functional decline and higher rates of institutionalization. Depression often can be differentiated from Alzheimer disease and other dementias based on characteristics of clinical history and presentation. Screening of depression and cognitive impairment will help characterize the presence and severity of these conditions, but limitations in screening approaches may necessitate comprehensive assessment in complex cases where differential diagnosis is important to treatment planning. CONCLUSION Although depression and cognitive impairment are important issues in the treatment of older adults, there are particular risks when they occur together. Appropriate assessment and screening can help guide the clinician to appropriate and timely interventions. Pharmacologic and nonpharmacologic treatment approaches are both efficacious in reducing depression in cognitive impairment and dementia.

Abstract
BACKGROUND/AIMS To compare the prevalence and characteristics of depression in vascular dementia (VaD) and Alzheimer's disease (AD) after adjusting for dementia severity and gender. METHODS One hundred and eight pairs of VaD and AD patients matched for dementia severity and gender were assessed. RESULTS Major depressive disorder (MDD) was more prevalent in the VaD group than in the AD group (20.4% in VaD, 10.2% in AD, p = 0.04, Cochran-Mantel-Haenszel, CMH, test) regardless of the dementia severity and gender. The odds ratio for developing MDD in the VaD group versus the AD group was estimated to be 2.20 (95% confidence interval = 1.02-4.74). Neurovegetative symptoms such as 'felt tired and weak all the time' (30.6% in VaD, 13.9% in AD, p = 0.003, CMH test) and 'changed weight without trying' (16.7% in VaD, 6.5% in AD, p = 0.02, CMH test) were more prevalent in the VaD group than in the AD group. CONCLUSION Depression in VaD was quantitatively and qualitatively different from that in AD regardless of the severity of dementia and gender; depression was more prevalent, severer and more retarded and vegetative in VaD than in AD.

Abstract
Psychiatric disorders such as depression are common conditions in older adults. Depression presents similarly to younger adults, but with more psychotic symptoms and apathy. Research has suggested that genetics play a less important role in the etiology of depression in the elderly, but that other biological factors may be more significant. Vascular pathology in particular is thought to be especially important. White-matter hyperintensities are found in the frontal lobes and basal ganglia in greater numbers in older adults with depression, with damage to the frontal–subcortical circuits thought to be particularly important. It is associated with treatment resistance. Prognosis is poor if depression is not detected and treated adequately and this may lead to a higher risk of dementia and death. However, treatment with selective serotonin reuptake inhibitors and other antidepressants, plus psychological therapies, are effective in the older depressed patient and reduce morbidity and mortality.

Abstract
Cerebrovascular disease is increasingly recognized as a common cause of cognitive impairment and dementia in later life either alone or in conjunction with other pathologies, most often Alzheimer disease (AD). Progress in the field has been limited by difficulties in terminology; for example, use of the term dementia necessitates the presence of memory impairment, which is the norm in AD, but not in cognitive disorders associated with cerebrovascular disease. The term vascular cognitive impairment (VCI) has been proposed as an umbrella term to recognize the broad spectrum of cognitive, and indeed behavioral, changes associated with vascular pathology. It is characterized by a specific cognitive profile with predominantly attentional and executive impairments together with particular noncognitive features (especially depression) and a relatively stable course, at least in clinical trial populations. Subtypes of VCI have been proposed based on clinical and pathologic differences, including cortical, subcortical, strategic infarct, hypoperfusion, hemorrhagic, and mixed (with AD) type. Diagnostic criteria are emerging but require refinement and validation, especially for mixed dementias. There remain fundamental gaps in our understanding of pathophysiology, predicting prognosis and outcome, and in therapeutics. Clinical trials to date, mainly in populations selected using currently accepted criteria for vascular dementia, have generally been disappointing. A relatively modest cognitive benefit of agents such as nimodipine, memantine, and cholinesterase inhibitors has been reported, although the clinical significance of these improvements remains to be established. Further studies, focusing on particular subtypes of VCI and involving subjects at earlier stages of the disease, are required. The aim of this article is to review the concept of VCI in terms of the evidence base surrounding diagnosis, clinical features, pathophysiology, and management and to make some recommendations regarding further research in the area. It begins with a discussion on the historical background, which is important to understand the different and somewhat confusing terminology that currently exists in the field.

Abstract
The higher prevalence of depression in specific diseases and older persons is discussed. This prevalence varies greatly according to the method used to collect data. A risk group can only be defined if information on diseases and other influencing factors are collected uniformly. The target diagnoses Parkinson's disease, stroke, myocardial infarction, cancer, diabetes mellitus, chronic pain, multiple infarct syndrome, Alzheimer's and other dementia were recorded from 1208 geriatric patients of the ZAGF municipal hospital in Munich, Germany. Logistic regression was used to identify chronic pain as the main cofactor for an association with depression (clinical diagnoses by ICD-10) and depressive symptoms (via GDS [Geriatric Depression Scale]). This association was also found for multimorbid patients with chronic pain. Impairment of the activities of daily living and the clinical setting were important additional cofactors. Pain patients are therefore at higher risk for depression.

Abstract
Anxiety and agitation are common in people with dementia. Their consequences can be severe, including increased mortality rates and institutionalization. Despite the importance of these symptoms there is little literature in this area. Some studies have assumed that agitation is the outward manifestation of anxiety, while others have attempted to differentiate between them. The aim of this study was to investigate the relationship between anxiety and agitation in people with mild-to-moderate dementia. A secondary aim was to compare two measures of anxiety which have been used in people with dementia. A cross-sectional correlation design was used. Participants were 40 older adults with dementia. Agitation, anxiety, depression, and level of cognitive impairment were measured. The main finding from the study was that anxiety and agitation are associated in dementia. The degree of correlation did not support the use of agitation as a measure of anxiety. Anxiety symptoms of autonomic sensitivity were not correlated with agitation and could be used to differentiate between the two if this was required. The use of the Rating for Anxiety in Dementia (RAID) was supported as a measure of anxiety in people with dementia.

Abstract
AIMS To study cardio-cerebrovascular disease and clinical features, such as falls, dizziness/unsteadiness, urinary incontinence, hallucinations/delusions and delirium in neuropathologically defined subgroups of vascular Dementia (VaD): pure Small Vessel Dementia (SVD), combined SVD and Alzheimer's disease (SVD-AD), pure Large Vessel Dementia (LVD) and pure Hypoxic Hypoperfusive Dementia (HHD), and to analyse the clinical differences between these groups. MATERIALS AND METHODS From 175 consecutive cases with neuropathologically verified VaD cases with pure SVD (n = 36) and SVD-AD (n = 38) with varying severity of AD pathology were selected and studied with respect to cardio-cerebrovascular and other clinical features. Furthermore, a comparison between pure SVD, pure LVD (n = 7) and pure HHD (n = 6) was made. RESULTS Neither cardiovascular symptoms, hypertension, Transitoric Ischemic Attacks (TIA) nor complete cerebrovascular lesions (CVL) differed significantly between the pure SVD and SVD-AD groups. However, a wide variation of clinical features were reported. The prevalence of cardiovascular features varied markedly in the pure groups, with the highest prevalence consistently found in the LVD group. Hypertension was common in the pure LVD and SVD-groups, while it was a rare finding in the HHD-group. TIA and/or CVL were, as expected, most common in the LVD-group. CONCLUSION In conclusion, this longitudinal and retrospective study of VaD shows important clinical similarities as well as differences between pathologically defined subgroups. Hopefully these findings will contribute to a better understanding of etiopathogenetic and diagnostic issues and form a solid basis for possible treatment strategies in VaD.

Previous studies investigating the serotonin transporter (SERT) in depression have been inconsistent and included a large proportion of subjects who had committed suicide. In Alzheimer's disease studies have generally reported a reduction in SERT density but have not compared Alzheimer's disease subjects with and without comorbid major depression. We conducted a post mortem study of SERT density in the prefrontal cortex in normal elderly, a group of elderly depressed subjects and in Alzheimer's disease subjects with and without major depression. A post mortem study comparing SERT density in the prefrontal cortex in elderly controls (n = 10), subjects with major depression (n = 8) and subjects with Alzheimer's disease with (n = 9) and without (n = 5) comorbid major depression. We used autoradiography to measure the density of [3H]CN-IMI binding (non-specific binding determined with citalopram) to the SERT in the prefrontal cortex. We found a marked reduction in specific SERT binding in the prefrontal cortex in Alzheimer's disease subjects compared with both control (P = 0.002) and depressed subjects (P = 0.004) but no difference in SERT binding between depressed and control subjects or between Alzheimer's disease subjects with and without depression. Our study confirms previous reports of a reduction in SERT binding in Alzheimer's disease but indicates this reduction is not greater in Alzheimer's disease subjects who also have had major depression. In a group of subjects more typical of late-life depression we did not identify any alterations in SERT density.

Abstract
Noncognitive behavioral and psychiatric disturbances are common in dementia and help in the clinical differentiation of the various subtypes. We studied the frequency of neuropsychiatric disturbances, their relationship to dementia severity and compared these disturbances in Alzheimer's disease (AD), vascular dementia (VaD) and frontotemporal dementia (FTD) using the 12-item Neuropsychiatric Inventory (NPI). A total of 98 patients (AD-44, VaD-31, FTD-23) were evaluated. All subjects were community dwelling at the time of evaluation. The three groups were comparable on global dementia severity and functional ability. All patients had clinically significant scores on the NPI with apathy, irritability and agitation being very common (>90% of patients). AD and VaD patients in Clinical Dementia Rating (CDR) stage 2 had significantly higher scores on the total NPI, agitation and disinhibition subscales compared to those in CDR stage 1. Mean scores in the domains of aberrant motor behavior, disinhibition and appetite/eating behavior differentiated FTD from AD and VaD. Neuropsychiatric disturbances in dementia appear to be universal with agitation, disinhibition and irritability being more frequent in the later stages. In this cohort disinhibition, aberrant motor behavior and appetite/eating disturbances could reliably differentiate AD and VaD from FTD. There were no significant differences between the neuropsychiatric profiles of AD and VaD.

Abstract
Depression is one of the leading causes of suffering in the elderly, but it is often under-diagnosed and under-treated, partly due to the false belief that depression is a common aspect of aging. Depression in the elderly is frequently comorbid with medical illnesses, may often be expressed by somatic complaints, and may be a risk factor for other diseases such as dementia and coronary artery disease. Depression decreases the quality of life and increases disability and the risk of mortality, also due to suicide. Although several effective antidepressant drugs are available, with a favorable therapeutic index, non-pharmacological treatments, such as psychotherapy and exercise, should receive greater attention, since combination therapy is probably more effective.

Abstract
This article reviews the prevalence and incidence of mental disorders in older adults. The authors outline the epidemiologic challenges in determining the frequency of mental disorders in late-life and discuss issues that are critical for understanding the prevalence of the disorders and for reviewing the evidence from epidemiologic studies of mental disorders in this population. The authors summarize the epidemiologic data for depression, anxiety, dementia, schizophrenia, and alcoholism. Also included is a discussion of risk factors and outcomes of these disorders and a discussion of the implications of these epidemiologic findings for geriatric medicine.

Abstract
OBJECTIVE The aim of the study was to empirically investigate the hypothesis that anxiety in the elderly, secondary to loss of memory, predicts future cognitive decline. METHOD The participants were 137 elderly subjects with no depression or cognitive impairment from a community geriatric assessment unit, 45% with anxiety. In addition to demographic characteristics, cognitive status was assessed using the Mini Mental State Examination; depression was assessed by Tucker's short Interviewer-Assisted Depression Rating Scale; anxiety by Sinoff's Short Anxiety Screening Test and Activities of Daily Living function by Shah's modified Barthel's Index. RESULTS At follow-up 37 persons had dropped out, leaving 100 participants for final analysis. Mean re-examination time was 3.2 years with no group differences. The mean MMSE and modified Barthel scores decreased significantly more in those with anxiety. A relative risk of 3.96 for developing future cognitive impairment was found. Regression analysis showed that only anxiety was a significant predictor of cognitive decline. By path analysis, a more parsimonious model showed anxiety to have both a direct and an indirect effect on predicting future cognitive decline, and that the effect of loss of memory on cognitive decline was via anxiety. CONCLUSIONS Anxiety is inter-related and inseparable with loss of memory and its presence is a strong predictor for future cognitive decline, directly or indirectly via depression. It appears that loss of memory is the initial problem with consequent development of anxiety. Therefore, anxiety, like depression, is probably an early predictor of future cognitive decline and even possible future cognitive impairment.

Abstract
An estimated four million individuals in the United States have Alzheimer's disease (AD). This number is expected to more than triple by mid-century. Primary care physicians have a key role in evaluating older patients for early signs of dementia and in initiating treatment that can significantly retard its progression over the maximum period of time. That role and its challenges will inevitably grow along with the expected increase in the population aged 65 and older. The tendency for physicians to dismiss memory complaints as normal aging must be replaced by awareness of the need to assess and possibly intervene. Early intervention is the optimal strategy, not only because the patient's level of function will be preserved for a longer period, but also because community-dwelling patients with AD incur less societal cost than those who require long-term institutional placement. Institutionalization contributes heavily to the annual cost of care for AD in the United States, which is estimated to be 100 billion dollars annually.

Abstract
Two important prerequisites for assessing therapeutic benefits in patients with vascular dementia (VaD), or Alzheimer's disease (AD) with cerebrovascular disease (CVD), are the inclusion of appropriate patients and the use of relevant outcome measures. There is substantial overlap in the clinical symptomatology, risk factors, imaging changes, pathophysiology and neurochemical mechanisms between VaD, AD and AD with CVD. While validated and acceptable clinical criteria suitable for clinical trials have been developed for VaD, there is still debate as to how mixed cases (i.e. AD with CVD) are best conceptualized. As with AD, there is consensus that outcome measures in studies of patients with VaD, or AD with CVD, should include assessments of cognitive and global function, of ability to perform activities of daily living (ADL) and of behavioral symptoms. Other measures, e.g., caregiver burden, would be desirable. Care must be taken in extrapolating AD-specific evaluations to VaD, however, because different specific domains are affected and the disease course is different. In clinical trials, cognitive performance and global function decline steadily in patients with untreated AD compared with smaller changes in patients with untreated VaD, while behavior and ADL deteriorate over 6 months in patients with either untreated AD or untreated VaD. Such differences in untreated outcome need to be considered when interpreting trial results using outcome measures that were largely designed for studies of patients with AD.

Abstract
Psychotic symptoms--delusions, delusional misidentifications and hallucinations--are observed in a variety of organic or nonorganic conditions, and are, therefore, diagnostically nonspecific. Common patholophysiologic denominators of different organic diseases may offer insights into the origin of psychotic symptoms. This article reviews some of the clinical and neuroimaging findings in organic psychoses present in various organic disorders. It attempts to extract a number of hypotheses about underlying biologic factors contributing to the development of psychotic symptoms of organic origin.
