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 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.
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.
As you begin to recover, you might feel that your behaviour changes or improves. You may start feeling better physically and emotionally. But some changes will be long term. You are still the same person, but a stroke may change the way you respond to things.
Cognitive problems are usually worst during the first few months after a stroke, but they can and do get better. They're likely to improve most quickly over the first three months, as this is when your brain is at its most active, trying to repair itself.
People who have had a stroke have a greater risk of dementia than people who have not had a stroke. About 1 in 10 people who have a stroke develop signs of dementia within 1 year. Vascular dementia is most common in older people, who are more likely than younger people to have vascular diseases.
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.
Can memory loss after stroke be treated? Memory can improve over time, either spontaneously or through rehabilitation, but symptoms can last for years. Your memory loss may benefit from medications for related problems, such as anxiety, depression or sleeping problems.
Stroke impacts the brain, and the brain controls our behavior and emotions. You or your loved one may experience feelings of irritability, forgetfulness, carelessness or confusion. Feelings of anger, anxiety or depression are also common.
It can be helpful to think of dementia progressing in three stages – early, middle and late. These are sometimes called mild, moderate and severe, because this describes how much the symptoms affect a person.
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.
Few patients recover fully and most are left with some disability, but the majority exhibit some degree of spontaneous recovery. Doctors and scientists don't fully understand how this happens, because the brain does not grow new cells to replace the ones damaged by the stroke.
Gains can happen quickly or over time.
The most rapid recovery usually occurs during the first three to four months after a stroke, but some survivors continue to recover well into the first and second year after their stroke.
After six months, improvements are possible but will be much slower. Most stroke patients reach a relatively steady state at this point. For some, this means a full recovery. Others will have ongoing impairments, also called chronic stroke disease.
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.
