老年期痴呆的发病率与预后 总被引:5,自引:1,他引:4
阎芳 《临床精神医学杂志》2001,11(1):40-43
老年期痴呆是指发生于老年期或由成年延续下来的痴呆,主要类型为阿尔茨海默病痴呆与脑血管性痴呆,ICD-10将阿尔茨海默病痴呆依发病年龄于65岁前或后分为早发性或晚发性[1]。在21世纪,人口老龄化将达到历史上前所未有的规模和程度。我国以60岁为老年期的年龄界限,预计2000年我国60岁以上的老年人将达到1.3亿,本世纪中叶可能达到4亿左右[2]。现就有关老年期痴呆的发病率及其预后的研究作一简单的回顾。 相似文献

Neuroanatomical correlates of clinical misidentification and misperception in senile dementia of the Alzheimer type 总被引:1,自引:0,他引:1
BACKGROUND: Impaired frontal lobe and/or nondominant hemisphere lesions have been described in patients with typical misidentification syndromes (e.g., Capgras' syndrome or reduplicative paramnesia) who had various underlying psychiatric or neurologic disorders. In a prospective long-term study, the authors examined computed tomography measurements of patients with senile dementia of the Alzheimer type (DAT) to determine whether the forms of misidentification they suffered might correlate with organic factors. METHOD: One hundred twenty-eight consecutive DAT patients were examined by means of standardized clinical instruments (Mini-Mental State score, CAMCOG, the Benton facial recognition test, the Kendrick object learning test, CAMDEX, and the Geriatric Mental State Schedule) and computed tomography. RESULTS: Of the 128 patients, 40 showed symptoms of misidentification; 25 of them misidentified other people in their homes, 7 misidentified their own mirror images, and 7 misidentified television images as being real. Computer-assisted planimetric computed tomography measurements showed that patients with misidentification syndromes had significantly larger right anterior horn areas of the lateral ventricle and significantly larger left anterior brain areas than did patients without such symptoms. CONCLUSIONS: The authors conclude that an accentuated degeneration of the right frontal lobe (and a relative preservation of the left frontal lobe) may be associated with delusional misidentification symptoms in DAT. 相似文献

We report here on the coexistence of dementia and depression in a community population aged 75 years and older. Complete information about mood and cognition was available for 286 cognitively intact subjects selected for assessment because of their low scores on the Mini-Mental State, and for 158 mildly and moderately demented subjects. Severely demented subjects, who were incapable of providing information, were excluded. Five percent (8/158) of demented subjects also fulfilled criteria for major depressive disorder Diagnostic and Statistical Manual of Mental Disorders, third edition (DSM-III) compared with 9% (27/286) of cognitively intact subjects. No substantial differences existed in the symptoms reported by demented depressives and nondemented depressives, but subjects who suffered from both disorders were so markedly apathetic that their depression might easily have been overlooked had specific enquiries not been made. Depression was particularly associated with dementia secondary to multi-infarct and Parkinson's disease. When reviewed one year later, 2 of the 18 surviving depressed, nondemented subjects showed evidence of dementia. Both presented unusual diagnostic difficulties, however, and no evidence emerged that large numbers of elderly people will be misclassified in community surveys that include a mental state examination, cognitive testing, and an informant interview. 相似文献

The aim was to investigate the incidence rate of dementia for community residents aged 85 years and over. It was a two wave community study of 224 subjects (community residents including those residing in a nursing home) older than 85 years, restudied 4.1 years after a community prevalence study. A two stage method was used, comprising the mini mental state examination followed in a stratified sample by the geriatric mental state schedule (A3)/AGECAT. Incidence rates were based on person-years at risk. The overall incidence of dementia was 6.9 (95% confidence interval (95% CI) 4.8-9.1) per 100 person-years at risk. The incidence was significantly higher for women than for men; respectively 8.9 (95% CI 5.9-11.9) v 2.7 (95% CI 0.5-4.9) per 100 person-years at risk. In the fastest growing age group seven out of 100 persons develop dementia each year. Women, who constitute two thirds of the oldest old, seem to have a higher risk. Further research is needed into the risk factors for dementia in this age group. 相似文献

The effect of supplements of vitamins B-1, B-2, niacin, B-6 and C has been assessed in a randomized double-blind trial in 15 hospitalized elderly patients suffering from senile dementia. Supplementation did not prevent an increase in either cognitive impairment or behavioural disturbance. However, it did result in weight gain over a six-week period. Hospitalized demented patients generally suffer significant weight loss, which increases with the duration of hospitalization. Vitamin supplementation may therefore protect against physical deterioration and the development of cachexia. 相似文献

The circadian organization of adrenal secretion was studied in 23 healthy elderly subjects, 23 elderly demented patients and 10 healthy young subjects, in order to investigate the relationships between the hypothalamic-pituitary-adrenal axis and some cerebral morphometric parameters. The cerebral morphometric analysis was performed in some subjects of the three groups by MRI. A significant increase in cortisol levels during evening and nighttime was found in both groups of the aged subjects. In elderly subjects, particularly if demented, the mean serum dehydroepiandrosterone sulfate (DHEAs) levels throughout the 24-hour cycle were significantly lower than in young controls. A significant reduction of the hippocampal and temporal volume and an enlargement of the lateral ventricles were found in aged subjects, these changes being significantly related to subjects' age. Moreover, the hippocampal volume was positively correlated with the circadian mesor of DHEAs (i.e., the circadian rhythm adjusted mean) and with the cortisol nocturnal increase. Our data may suggest the existence of a link between the selective impairment of cortisol secretion and DHEAs levels, and the progression of hippocampal degeneration. 相似文献

Early detection of senile dementia. Apropos of the congress on "Current problems in senile dementia"
C Gilles 《Acta psychiatrica Belgica》1987,87(5):620-623
While research in neurochemistry, genetics and molecular biology progresses in understanding Alzheimer's disease, no therapeutic strategy has hitherto been demonstrated useful. Early detection and diagnosis of dementias are thus equally important. The major part of this symposium was devoted to advances of research in this field. New techniques of clinical assessment, metabolic imaging and brain mapping are promising tools for early diagnosis. 相似文献
