Strokes that block a brain artery usually cause a range of symptoms that may include vascular dementia. But some strokes don't cause any noticeable symptoms. These silent strokes still increase dementia risk.
Vascular dementia, which is commonly associated with left-hemisphere stroke, impacts reasoning, planning, judgment, memory and other thought processes. It's caused by brain damage from impaired blood flow and other conditions that damage blood vessels and reduce circulation.
Almost a quarter of people who have had a stroke will go on to develop dementia after about three to six months.
How Does a Stroke Impact Life Expectancy? Despite the likelihood of making a full recovery, life expectancy after stroke incidents can decrease. Unfortunately, researchers have observed a wide range of life expectancy changes in stroke patients, but the average reduction in lifespan is nine and a half years.
About 1 in 4 people who have had a stroke will go on to develop signs of dementia. Vascular dementia is most common in older people, who are more likely than younger people to have vascular diseases. It is more common in men than in women.
The stroke recovery process is long and can come with many challenges, including the feeling that symptoms are getting worse instead of better. However, know that regression after stroke is common and often temporary. This can be impacted by factors such as new medications, schedule changes, or excess fatigue.
Vascular dementia happens when the blood supply to parts of your brain becomes reduced. This can be due to blood vessels being clogged, a stroke or a series of small strokes. Over time, areas of brain cells stop working, leading to symptoms of dementia.
A 2021 systematic review and meta-analysis reports that, at any given time after a stroke, 16.5% of people experience dementia.
The brain damage that occurs with a stroke or a ministroke (transient ischemic attack) may increase your risk of developing dementia.
A stroke can lead to changes in your behaviour. This can be due to the damage to your brain, or it might be linked to emotional problems.
If a person has a brain scan and their doctor detects one or multiple silent strokes, they may prescribe medications. For instance, blood thinning medications can help to lower blood pressure, and cholesterol medications can help to lower low-density lipoprotein (LDL) cholesterol.
A silent stroke refers to a stroke that doesn't cause any noticeable symptoms. Most strokes are caused by a clot that blocks a blood vessel in the brain. The blockage prevents blood and oxygen from reaching that area, causing nearby brain cells to die.
The Mini-Cog test.
A third test, known as the Mini-Cog, takes 2 to 4 minutes to administer and involves asking patients to recall three words after drawing a picture of a clock. If a patient shows no difficulties recalling the words, it is inferred that he or she does not have dementia.
Administration: The examiner reads a list of 5 words at a rate of one per second, giving the following instructions: “This is a memory test. I am going to read a list of words that you will have to remember now and later on. Listen carefully. When I am through, tell me as many words as you can remember.
Alzheimer's disease, the most common dementia diagnosis among older adults. It is caused by changes in the brain, including abnormal buildups of proteins known as amyloid plaques and tau tangles.
Just like in life, personality after stroke will continue to change over time. Immediate changes in personality are not always permanent and there are things that can help. Cognitive behavioural therapy. Helps you identify and change unhelpful thought patterns, creating a more positive and problem-solving approach.
Even after surviving a stroke, you're not out of the woods, since having one makes it a lot more likely that you'll have another. In fact, of the 795,000 Americans who will have a first stroke this year, 23 percent will suffer a second stroke.
On average, between 10 and 15 years after stroke, 25% of survivors were moderately-severely disabled, 21% were inactive, 22% had cognitive impairments, 32% were anxious and 38% depressed. Functional, cognitive and psychological outcomes between 10 and 15 years after stroke.
For example, 79% of people survive 2 years, 61% survive 3 years, …, 5% survive 16 years, and only 1% survive 20 years.
Vascular dementia – around five years. This is lower than the average for Alzheimer's mostly because someone with vascular dementia is more likely to die from a stroke or heart attack than from the dementia itself. Dementia with Lewy bodies– about six years.
