Division of Psychiatry, United Medical and Dental Schools (Guy's), Bexley Hospital, Kent, UK.

The mydriatic response to eyedrops of the anticholinergic drug tropicamide at very low concentration (0.01%) was studied in subjects with Alzheimer's disease (AD, n = 10) and multi-infarct dementia (MID, n = 10). There was no significant difference in pupillary response between the two groups. The test is unlikely to be useful in differentiating different types of dementia.

D000544	Alzheimer Disease	A degenerative disease of the BRAIN characterized by the insidious onset of DEMENTIA. Impairment of MEMORY, judgment, attention span, and problem solving skills are followed by severe APRAXIAS and a global loss of cognitive abilities. The condition primarily occurs after age 60, and is marked pathologically by severe cortical atrophy and the triad of SENILE PLAQUES; NEUROFIBRILLARY TANGLES; and NEUROPIL THREADS.
