One type of vascular dementia involving many strokes is called multi-infarct dementia. With both silent and apparent strokes, the risk of vascular dementia increases with the number of strokes that occur over time. These silent strokes still increase dementia risk. But some strokes don't cause any noticeable symptoms. Strokes that block a brain artery usually cause a range of symptoms that may include vascular dementia. Stroke (infarction) blocking a brain artery. Vascular dementia results from conditions that damage your brain's blood vessels, reducing their ability to supply your brain with the amounts of nutrition and oxygen it needs to perform thought processes effectively.Ĭommon conditions that may lead to vascular dementia include: Studies show that many people with dementia and evidence of brain vascular disease also have Alzheimer's disease. What's more, vascular disease and Alzheimer's disease often occur together. Changes in your thought processes occur in noticeable steps downward from your previous level of function, unlike the gradual, steady decline that typically occurs in Alzheimer's disease dementia.īut vascular dementia can also develop very gradually, just like Alzheimer's disease dementia. Sometimes a characteristic pattern of vascular dementia symptoms follows a series of strokes or ministrokes. When changes in your thinking and reasoning seem clearly linked to a stroke, this condition is sometimes called post-stroke dementia. Vascular dementia symptoms may be most clear-cut when they occur suddenly following a stroke. Sudden or frequent urge to urinate or inability to control passing urine.Decline in ability to analyze a situation, develop an effective plan and communicate that plan to others.Reduced ability to organize thoughts or actions.Trouble paying attention and concentrating.Vascular dementia signs and symptoms include: But unlike Alzheimer's disease, the most significant symptoms of vascular dementia tend to involve speed of thinking and problem-solving rather than memory loss. Symptoms often overlap with those of other types of dementia, especially Alzheimer's disease dementia. Vascular dementia symptoms vary, depending on the part of your brain where blood flow is impaired.
