Question

Which of the following best explains why mood disorders are more characteristic of vascular dementia (VAD) than of Alzheimer's disease?

A) Alzheimer's disease primarily affects cognitive functions, leaving mood unaffected.
B) Vascular dementia often involves damage to brain areas controlling mood regulation.
C) The genetic predisposition for mood disorders is higher in individuals with VAD.
D) Alzheimer's disease is associated with a higher degree of cognitive resilience than VAD.

Answer 1

Vascular dementia (VAD) often involves damage to brain areas controlling mood regulation, leading to mood disorders. Alzheimer's disease primarily affects cognitive functions and leaves mood relatively unaffected.

Step-by-step explanation:

Vascular dementia (VAD) is more characteristic of mood disorders than Alzheimer's disease because VAD often involves damage to brain areas controlling mood regulation. This damage can lead to changes in a person's emotional state, resulting in mood disorders.

On the other hand, Alzheimer's disease primarily affects cognitive functions and leaves mood relatively unaffected. Therefore, option B is the best explanation for why mood disorders are more characteristic of VAD than Alzheimer's disease.
