We examined 2,029 volunteers 50 to 93 years of age in a cross-sectional
study of nine bedside neurologic tests to determine the frequency of
"abnormal" responses in uncomplicated aging (senescence). Rates of abnormal
responses remained constant until age 70 years, after which they increased
significantly. The number of abnormal signs per subject also increased,
especially over 70 years of age. These results provide normative data
against which these signs may be compared when applied as a clinical
screening battery for diffuse cerebral dysfunction.
