This is the second most common type of dementia in younger people. Around 20% of young people with dementia have vascular dementia. It can occur when blood flow to the brain is restricted, often through a series of small strokes. Memory, speech, language and learning are affected and the condition progresses over time. People often see a step change in their abilities. The condition can stabilise for some time before declining further.
People can have both vascular dementia and Alzheimer’s disease.
