摘要
We investigated the relationship between extrapyramidal signs (EPSs) in patients diagnosed with Alzheimer disease (AD) and the average rate of decline in different areas of cognition. The presence of tremors, cogwheel rigidity, or bradykinesia were scored as EPS using the California State Department of Health Services AD Diagnostic and Treatment Center Form. Measures of decline were computed by determining patients' average rates of decline on the Mini-Mental State Examination (MMSE). Of the 81 patients, 24 were determined to have EPS not related to medications. Overall, patients with EPS deteriorated 67% faster on MMSE (4.5 points per year) than did patients with no evidence of EPS (2.7 points per year). Our findings indicate that the clinical presence of EPS is a poor overall prognostic sign in patients with a clinical diagnosis of AD.
