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.
Almost a quarter of people who have had a stroke will go on to develop dementia after about three to six months.
Recent research also revealed stroke is the major factor for vascular dementia (VaD) and Alzheimer's disease (AD).
If a person has several smaller strokes over time, multiple infarcts will build up in their brain. They may eventually develop dementia if the combined damage of all these infarcts is enough to cause problems with memory, thinking or reasoning.
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.
Cerebral infarction and brain hemorrhage are the most common causes of memory loss.
Dementia often gets worse over time. 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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Up to 60% of all stroke survivors develop memory and thinking problems within a year, and one-third go on to develop dementia within five years, according to a new American Stroke Association scientific statement.
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.
The short answer is yes; the brain can heal after acute trauma from a stroke or brain injury, although the degree of recovery will vary. The reason the brain can recover at all is through neuroplasticity, sometimes referred to as brain plasticity.
