Which cognitive function is least likely to be affected by vascular dementia?

Memory is the cognitive function least likely to be affected by vascular dementia because this type of dementia primarily impacts the brain areas responsible for executive functions due to compromised blood flow. Vascular dementia often leads to difficulties in judgment, planning, and visual-spatial abilities because these functions rely heavily on the processing and integration of various cognitive skills, which can be impaired due to vascular changes in the brain.

While memory can also be affected by vascular dementia, it tends to remain relatively intact in the early stages compared to other cognitive functions. Patients may have episodic memory issues, but the profound impacts on executive function typically overshadow these effects. This distinction is crucial when evaluating a patient suspected of having vascular dementia, as it can guide treatment and management strategies.
