Abstract

Cognitive Impairment and Endorsement of Depression
Typically, as cognitive deficit increases, endorsement of depression decreases, which is suggestive of a paradox since more difficulty with daily functioning is associated with increased depression. However, a key element is the construct of insight. The purpose of the present evaluation was to examine how cognitive impairment influenced endorsement of depression, particularly in patients diagnosed with Alzheimer’s disease, as lack of insight is a core feature. Analysis of archival data involved 82 patients and neurocognitive data including the Brief Visuospatial Memory Test-Revised (BVMT-R), Hopkins Verbal Learning Test, Revised Edition (HVLT-R), and the Geriatric Depression Scale (GDS). Overall sample endorsement of depression was minimal (GDS =6.76, SD=0.61) while overall visual and verbal delayed recall were impaired (BVMT-R T=27.42, SD=0.93; HVLT-R T=28.65, SD=1.05). The sample demonstrated clinically significant positive correlation between delayed visual recall and endorsed depression (r=0.25, p=.02) but not between delayed verbal recall and endorsed depression (r=0.22, p=.05). Those diagnosed with major or mild neurocognitive disorder due to Alzheimer’s disease were significantly less likely to endorse significant depression than those diagnosed with other neurodegenerative diagnoses in the older adult population, x² (1, N=82)=7.50, p=.01. Overall, results suggest impaired self-report of depression in these populations.
