Diagnosis of Dementia-Circadian Dependency?
Journal Title: Journal of Geriatric Medicine and Gerontology - Year 2017, Vol 3, Issue 1
Abstract
Little is known whether tests used for the diagnosis of dementia syndromes are sensitive to time of day effects. In a sample of 145 participants, no such effect (test administration either in the morning from 9.30 to 11.30 a.m. or in the afternoon from 2.30 to 4.30 p.m.) could be found for most subtests of a neurocognitive test battery (CERAD-Plus) used for the detection of dementia syndromes. However, for subjects suffering from mild cognitive impairment, completion time for the Trail-Making Test B, a brief cognitive test for the assessment of cognitive flexibility, was longer in the afternoon compared to the morning.
