To perform such a study, we developed a quantitative assessment that includes the major components of a standard bedside neurologic evaluation, with special emphasis on cognitive function. First, we demonstrated that the quantitated examination could correctly classify healthy controls and patients with stroke or dementia based on discriminant analysis. This examination was then applied to healthy community-dwelling elderly ranging from 60 to 108 years of age. Significant age-related neurobehavioral changes were apparent across even these most \u201csuccessfully\u201d aged groups. Analysis of the full pattern of cognitive and neurologic findings provided the most accurate assessment. Pathologic reflexes, reportedly associated with normal aging, occurred infrequently in this healthy geriatric population, suggesting that age-related changes in the neurologic examination may be more accurately interpreted when assessed in conjunction with cognitive status. This quantitative examination may be useful in future population-based studies of neurologic function in the aged.<\/jats:p>","DOI":"10.1177\/089198879400700101","type":"journal-article","created":{"date-parts":[[2007,3,11]],"date-time":"2007-03-11T04:39:55Z","timestamp":1173587995000},"page":"1-7","source":"Crossref","is-referenced-by-count":11,"title":["Age-Related
