Question

A patient with arteriosclerosis has been newly diagnosed with vascular dementia after wandering away from home and getting lost. What is the most likely cause of the patient's dementia?

1) Alzheimer's disease
2) Parkinson's disease
3) Huntington's disease
4) Vascular dementia

Answer 1

The patient's dementia is most likely caused by vascular dementia, which is associated with reduced blood flow to the brain due to arteriosclerosis.

Step-by-step explanation:

The most likely cause of the patient's dementia, given their diagnosis of arteriosclerosis and subsequent vascular dementia, is vascular dementia. This condition is distinct from Alzheimer's disease, Parkinson's disease, and Huntington's disease, which also cause dementia but have different underlying pathologies. Vascular dementia is caused by reduced blood flow to the brain, which can be a consequence of conditions like arteriosclerosis, leading to brain damage and the dementia symptoms the patient is experiencing.
