Answer:
Vascular Dementia
Explanation:
Cognitive impairment is when someone has difficulties in memorizing things, learning new ideas or remembering past events or making decisions.
A severe and worsened cognitive impairment can lead to vascular occlusion which is primarily the blockage of blood vessels in the brain which lead to reduced flow of blood in the brain. Which leads to stroke.
Vascular Dementia is caused by reduction in blood flow or blockage of blood arteries in the brain which gives rise to multiple strokes. And in severe cases would lead to death.
