We reanalyzed and compared current prevalence estimates of Alzheimer's disease in Europe. Studies characterized as follows qualified for comparison: dementia defined by the Diagnostic and Statistical Manual for Mental Disorders, 3rd edition, or equivalent criteria; Alzheimer's disease diagnosed by the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association or equivalent criteria; case-finding through direct individual examination; appropriate sample size; and inclusion of institutionalized persons. Of the 23 European surveys of dementia considered, six fulfilled the inclusion criteria. When age and sex were considered, there were no major geographic differences in the prevalence of Alzheimer's disease across Europe. Overall European prevalence (per 100 population) for the age groups 30 to 59, 60 to 69, 70 to 79, and 80 to 89 years was, respectively, 0.02, 0.3, 3.2, and 10.8. Prevalence increased exponentially with advancing age and, in some populations, was consistently higher in women. Prevalence remained stable over 15 years in one study.

An unselected community sample of 128 patients were studied over the 12 months after their first stroke, and compared with a control sample of subjects from the general population. Psychiatric status was assessed using the PSE and BDI. Symptoms of mood disorder were commoner in the stroke patients than the controls, but the differences were not substantial and had largely disappeared by 12 months. Psychiatric problems encountered included agoraphobia, social withdrawal, apathy and self-neglect, irritability and pathological emotionalism. While there was a high cumulative incidence of psychiatric disorder, little of it persisted: only two cases of major depression were present for the whole 12 months. We believe undue emphasis has been placed in the recent literature on major depression as a specific syndrome following stroke.

A stratified random sample of 83 black and 81 white community residents aged 65 years and older in a five-county area in the Piedmont region of North Carolina was evaluated for dementia, using the Diagnostic and Statistical Manual of Mental Disorders, Third Edition, and the National Institute of Neurological Disorders and Stroke--Alzheimer's Disease and Related Disorders Association criteria. Of 164 subjects, 26 were found to be demented, resulting in an estimated prevalence rate of dementia in the five-county area of 16% (95% confidence interval, 7.92 to 24.08) for blacks and 3.05% (95% confidence interval, 0 to 6.91) for whites. The estimated prevalence of dementia for white women (2.9%) was similar to that for white men (3.3%), but the rate for black women was distinctly higher than for black men (19.9% and 8.9%, respectively). Blacks were more likely than whites to have a history of stroke, hypertension, and other chronic disorders that might have contributed to the development of dementia. Apart from differences in rates of institutionalization, no other relevant factors were identified that might explain the difference in the prevalence of dementia in these black and white community residents.

The prevalence, diagnosis, clinical presentation, evolution, and treatment of depression and mania following stroke are discussed. Among the many studies presented in the review is one that indicates major depression following right hemisphere lesions is associated with a positive family history of psychiatric disorder and lesions involving the parietal cortex. The co-occurrence of major depression and generalized anxiety disorder is associated with cortical lesions, while depression alone is associated with subcortical lesions. A recent study has also shown a strong association between mania and direct or indirect dysfunction of the basotemporal cortex in the right hemisphere. Possible mechanisms for both mania and depression following stroke are presented, and ideas for future directions in research are suggested.

Follow-up studies of psychiatric patients with panic disorder have shown an abnormally high mortality rate in men due to cardiovascular and cerebrovascular events. The authors report that in the New Haven portion of the Epidemiologic Catchment Area program the risk for stroke in persons with lifetime diagnoses of panic disorder was over twice that in persons with other psychiatric disorders or no psychiatric disorder. After adjustments for demographic differences between groups, the risk was even higher. While the results should be interpreted cautiously because of the small sample and absence of medical examinations, these findings are consistent with clinical studies showing an association between panic disorder and cardiovascular/cerebrovascular events.

A clinical study was made on depressive state following stroke using stroke patients in the chronic stage. There were 118 stroke patients in the present study and 25 patients (21.2%) satisfied the diagnostic criteria for major depressive syndrome of the Diagnostic and Statistical Manual of Mental Disorders, Third Edition Revised (DSM-III-R). As for dispositional, social, and somatic factors, a tendency was observed for depressive state to develop at a high frequency among patients with a past history of mental disorder prior to development of stroke, patients residing in suburban area, patients engaged in domestic and agricultural work, and patients with a frequent history of physical disorders. A tendency was observed for depressive state to develop at a high frequency among patients showing B type in YG test and patients presenting laterality in electroencephalography. Among the 49 right stroke patients, depressive state was observed in 10 cases (20.4%), while among the 43 left stroke patients, depressive state was seen in 10 cases (23.2%) with the incidence of depressive state showing no difference by hemisphere stroke. Study of the clinical characteristics of depressive state by hemisphere stroke with the use of symptom items of Zung scale and Hamilton scale showed that patients in depressive state with right hemisphere stroke had high values in symptom items considered close to the essence of endogenous depression such as depressed mood, suicide, diurnal variation, loss of weight, and paranoid symptoms, while patients in depressive state with left hemisphere stroke had high values in symptom items having a nuance of so-called neurotic depression such as psychic anxiety, hypochondriasis, and fatigue. Comparison with endogenous depression patients indicated that right stroke patients rather than left stroke patients showed a clinical picture suggestive of endogenous depression. Antidepressant was effective in 71.4% of the cases, but no difference in effectiveness could be observed by hemisphere stroke. In stroke patients in the chronic stage the incidence of clinical depressive state was higher than 20%, and involved in its onset were not only brain organ lesions but also dispositional, social, and somatic factors and integration dysfunction in the emotional activity of the left and right hemisphere functions. As for the clinical picture, a picture considered close to endogenous depression was observed in right stroke patients, while that considered close to so-called neurotic depression was seen in left stroke patients. The therapeutic effect of antidepressant was almost equivalent to that for endogenous depression.

We report the prevalence rates for dementia and Alzheimer's disease (AD) obtained from a probability sample survey of 5,055 noninstitutionalized older persons in Shanghai, China. A two-stage procedure was used for case finding and case identification. A Chinese version of the Mini-Mental State Examination was used to determine cases of possible dementia. Three different cutoff points on this mental status test were used depending on the respondent's level of education. Clinical evaluations, based on functional assessments and psychiatric interview, medical and neurological examinations, three standardized mental status tests, and a selected group of psychometric tests, were made in the second stage of the study to ascertain the clinical diagnosis of dementia and AD utilizing the Diagnostic and Statistical Manual for Mental Disorders, edition 3 and National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association criteria, respectively. The prevalence rate of dementia in persons 65 years and older was 4.6%. Clinically diagnosed AD accounted for 65% of the subjects with dementia. These findings indicate that the prevalence of dementia in Shanghai is very much higher than figures published earlier for China and Japan, and at the lower part of the range of values reported for community residents in the United States and other Western countries, but less than half of that reported in the recently published survey of the elderly in East Boston. Increasing age, gender (female), and low education are each highly significant and independent risk factors for dementia. One hypothesis to explain the increased prevalence in elderly women who had received no formal education invokes the possibility of an effect of early deprivation, perhaps lowering brain "reserve," allowing the symptoms of dementia to appear at an earlier date during disease progression.

In a community-based study of stroke survivors, we identified 73 consecutive patients with a stroke, the first ever in a lifetime, who had a CT scan which showed a neurologically appropriate single stroke lesion, and who did not have a psychiatric disorder in the year preceding the stroke. A detailed follow-up study of these patients using standardized psychiatric assessments failed to confirm a number of recent claims about poststroke depressive disorders. We found no evidence that left-sided lesions were associated with more severe or persistent depressive symptoms, or that right-sided lesions were associated with hypomania. The DSM III syndrome of major depression was much less common than has previously been reported, and was not specifically associated with lesions placed anteriorly in the left hemisphere. There was a weak correlation between mood symptom scores and the proximity of the stroke lesion to the frontal pole of the hemisphere, but no evidence of a difference between right and left hemisphere strokes in the nature of the relationship between lesion distribution and mood symptoms. We suggest that previous studies have different findings because of differences in the conventions applied to the definition and measurement of psychiatric disorders after stroke, and because other studies have concentrated on selected inpatient populations.

Depression appears to be common after stroke, and therefore may have a bearing upon rehabilitation. To examine whether the depression is due to a specific brain lesion, or is reactive to the consequent disability, this study looked at the frequency and associations of depressed mood in a stroke rehabilitation unit in-patient population, unselected for site of lesion. Depression affected 50% of the patients; history of previous psychiatric disorder and cerebrovascular accident appeared to be important risk factors. There were hemispheric differences in the relationships between measures, with both the site-of-lesion and reactive viewpoints being upheld.

Ninety-three patients with acute stroke lesions restricted to the right hemisphere were examined for the presence of mood changes. While 46 patients showed no mood changes, 19 were unduly cheerful, 17 had developed major depression, and 11 had developed minor depression. Although there were no significant between-groups differences in other demographic variables, neurological deficits, activities of daily living, cognitive impairment, or quality of social support, patients with major depression had a significantly higher frequency of familial history of psychiatric disorder and lesions of the parietal cortex than patients with either no mood change or major depression following left-hemisphere lesions. On the other hand, undue cheerfulness was significantly associated with lesions of the right frontal operculum. These findings suggest that major depression following right-hemisphere lesions may have a different aetiology and mechanism than major depression following left frontal or basal ganglia lesions.
