38/100

✓ Peer-reviewed alzhub usefulness score 38 out of 100. Cognitive tests and assessment

Topic: Risk, prevention and care in population studies

DLB patients had a higher prevalence of VH than AD patients (p < 0.01). The presence of VH predicted lower Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores in both DLB and AD patients (p < 0.01). In DLB patients, VH were associated with lower attention function scores after adjustment (p = 0.027). In AD patients, VH were related to worsened orientation ability after adjustment (p = 0.033). Attention function partially mediated the association between VH and cognition in DLB patients (p < 0.01), whereas orientation function partially mediated this association in AD patients (p < 0.01). VH may independently correlate with deterioration in global cognitive performance. In DLB patients with VH, attentional function appears to be more impaired, whereas in AD patients, orientation function is the most affected. Different cognitive domains may help distinguish between DLB and AD patients with VH.

Key findings

DLB patients had a higher prevalence of VH than AD patients (p < 0.01).
The presence of VH predicted lower Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) scores in both DLB and AD patients (p < 0.01).
In DLB patients, VH were associated with lower attention function scores after adjustment (p = 0.027).
In AD patients, VH were related to worsened orientation ability after adjustment (p = 0.033).
Attention function partially mediated the association between VH and cognition in DLB patients (p < 0.01), whereas orientation function partially mediated this association in AD patients (p < 0.01).

Why it matters

Visual hallucinations were more common in Lewy body dementia than Alzheimer's disease and were linked to lower cognitive scores in both, with attention most affected in Lewy body dementia and orientation most affected in Alzheimer's. Different cognitive domains may help distinguish these two dementias in patients with visual hallucinations, but this does not treat the condition.
