The brain damage that occurs with a stroke or a ministroke (transient ischemic attack) may increase your risk of developing dementia.
Almost a quarter of people who have had a stroke will go on to develop dementia after about three to six months.
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.
People who have had a stroke have a far greater risk of developing dementia than people who have not had a stroke. 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.
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.
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.
You or your loved one may experience feelings of irritability, forgetfulness, carelessness or confusion. Feelings of anger, anxiety or depression are also common. The good news is many disabilities resulting from stroke tend to improve over time. Likewise, behavioral and emotional changes also tend to improve.
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.
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.
Changes in your emotions and to your personality are common after stroke. It's very normal to experience strong emotions after stroke, however these emotional reactions usually get better with time. Longer-term emotional and personality changes can be very challenging.
Some of the more common triggers for dementia like a change in environment, having personal space invaded, or being emotionally overwhelmed may be easier to handle if you mentally practice your response before you react.
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.
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.
Symptoms can sometimes develop suddenly and quickly get worse, but they can also develop gradually over many months or years.
Over time, the disease causing the dementia spreads to other parts of the brain. This leads to more symptoms because more of the brain is unable to work properly. At the same time, already-damaged areas of the brain become even more affected, causing symptoms the person already has to get worse.
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.
For this reason, the 60 minutes after the onset of stroke symptoms are known as “the golden hour.” If treatment can be initiated within this brief window, the patient's outcome is likely to be better.
