A person’s life expectancy after a mini stroke reduces by around 4% in the first year following the attack in comparison to people who have not had one. In the following 9 years, life expectancy reduces by 20%.
These statistics come from a
A mini stroke, or transient ischemic attack (TIA), can happen if the blood supply to part of the brain reduces temporarily. It can cause stroke-like symptoms, such as weakness, numbness, and confusion, but it does not cause permanent damage.
However, a TIA increases the risk of stroke to
This article looks at life expectancy after a mini stroke and discusses stroke prevention.
Scientists analyze the impact of TIAs on life expectancy by looking at relative survival rates. This measures how many people survive over a certain period of time after the TIA in comparison to people who have not had one.
Experiencing a TIA increases the risk of stroke, particularly within the first couple of months following the event. Although some people fully recover following a stroke, life expectancy can decrease as a result of having one.
There is no recent research that has investigated the impact of TIAs on the survival rates of different age groups.
However, older research from 2011 indicates that TIAs have a minimal effect on life expectancy in people aged
Yes, many people who experience a mini stroke make a full recovery. Most symptoms last from only a
However, TIAs can be warning signs that a person is at risk of more serious conditions. Early diagnosis and treatment
No, mini strokes do not always lead to major strokes, but they can increase the risk. The early risk of stroke is around
If the person does not receive treatment, their risk of stroke within the following 5 years is around 20–30%. These people also have an increased risk of heart attack and other serious cardiac events.
Because TIAs can precede a stroke or raise the risk of having one, people should not hesitate in contacting their doctor if they believe they have had one. Medical professionals can help a person take steps to reduce their risk of stroke.
This may involve:
Smoking and secondhand smoke are
- damages blood vessels
- reduces oxygen in the bloodstream
- makes blood more sticky and likely to clot
- increases plaque buildup in blood vessels
Quitting smoking can significantly reduce a person’s risk of stroke. Even if a person has smoked for years, quitting reduces the risk of stroke
Within 8 hours of quitting, blood oxygen levels improve, and carbon monoxide and nicotine levels reduce by more than 50%. After 5 years of smoking cessation, stroke risk is the same as it is for a person who does not smoke.
Diet and exercise
Eating a balanced diet and exercising regularly can help maintain healthy cholesterol levels, which helps protect against stroke. People should aim to eat:
- plenty of fruits and vegetables
- lean proteins
- low-fat dairy
It is also important for a person to avoid processed foods and sugary drinks.
In addition, exercising for
Controlling blood pressure and health conditions
Lifestyle changes such as maintaining a moderate weight, eating a balanced diet, reducing stress, and exercising can help reduce blood pressure. Sometimes, people may need medication to lower their blood pressure.
Support and resources are available for people who have had a mini stroke or are at risk of having one. They include:
American Stroke Association, which connects people to support groups, runs a support hotline, and provides resources in Spanish
WISEWOMAN program, which provides free counseling on reducing the risk of cardiovascular disease to females across the United States
- the Stroke Support Association, which provides tips on accessing stroke support in a person’s community and a list of online resources
According to research, people who have a TIA, or mini stroke, have a slightly reduced survival rate during the following year in comparison to people who have not had an attack. This difference in survival increases over time.
TIAs elevate the risk of stroke. People can reduce their risk of stroke by quitting smoking, eating a balanced diet, exercising regularly, controlling blood pressure, and managing any existing medical conditions. A person may also need medications or other treatments to lower the risk.
People who would like support and guidance in recovering from a mini stroke, and reducing their risk of another stroke in the future, can contact a doctor for advice.
