Some brain cells die quickly but many linger in a compromised or weakened state for several hours. Stroke causes permanent brain damage over minutes to hours. With stroke, “time is brain,” meaning that the sooner treatment begins, the better.
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.
Right-sided weakness or paralysis and sensory impairment. Problems with speech and understanding language (aphasia) Visual problems, including the inability to see the right visual field of each eye. Impaired ability to do math or to organize, reason, and analyze items.
With each minute that passes, you lose about 2 million brain cells. The longer you go without oxygen, the greater your chance for brain damage that can't be undone. After about 10 minutes, the damage can be severe.
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 most common types of disability after stroke are impaired speech, restricted physical abilities, weakness or paralysis of limbs on one side of the body, difficulty gripping or holding things, and a slowed ability to communicate.
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.
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.
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.
It is possible to live a normal life after a stroke, but you will need to actively participate in your rehab. Brain injuries can affect mobility, swallowing, speech and, therefore, your ability to do the vital tasks of daily living. So, you will need help, support, counselling, encouragement, and loving care.
Although just 10% of people fully recover from a stroke, 25% have only minor impairments and 40% have moderate impairments that are manageable with some special care.
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.
The first question a stroke survivor should ask:
Did I have a white stroke or a red stroke? Of people who survive a first white stroke, within 1 year 8% will have another one (1), and within 2 years 11% will have a second one (2). In one study, 39% of second strokes were fatal (2).
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Family members share genes, behaviors, lifestyles, and environments that can influence their health and their risk for disease. Stroke risk can be higher in some families than in others, and your chances of having a stroke can go up or down depending on your age, sex, and race or ethnicity.
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.
Irrational, Impulsive, or Inappropriate Behavior
Impulsiveness in particular is often associated with both frontal lobe strokes and a stroke in the temporal lobe, which plays a role in judgement and decision-making, particularly when the right side is affected.
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.
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.
Problems that Occur After a Stroke
Most are common and will improve with time and rehabilitation. Common physical conditions after a stroke include: Weakness, paralysis, and problems with balance or coordination.
Strokes can lead to short-term and long-term cognitive and physical impairments. Even with extensive treatment, a stroke can leave a person with a permanent disability.
