A stroke occurs when a ruptured blood vessel or a blockage from a blood clot hinders or cuts off the blood supply to part of the brain. The duration of a stroke depends on the individual and the type of stroke.
Each year, around
How long a stroke lasts depends on the type of stroke and the individual. However, doctors may not be able to determine the exact duration of blood flow interruption in every person who has experienced one. The duration varies and can range from a
Individuals may experience shorter or longer strokes depending on their overall health and how quickly they receive treatment. In one study, the average time before stroke treatment effectively restored blood flow was 6.8 hours. The longer the blockage of blood flow, the more severe the damage and symptoms someone experiences.
During a hemorrhagic stroke, a ruptured blood vessel leaks within the brain. Bleeding within the brain can damage brain tissue. A ruptured blood vessel does not properly deliver blood to a region of the brain, similar to an ischemic stroke. Additionally, leaking blood can raise pressure within the skull, which may also lead to brain tissue damage.
The symptoms of a hemorrhagic stroke typically develop within minutes or hours. Generally, the pool of leaked blood on the brain enlarges within
Mini-strokes occur when a temporary blockage disrupts the blood supply to an area of the brain. They often signal more strokes to come. Individuals who experience a mini-stroke should speak with their doctor to learn about preventing future strokes.
It is crucial to recognize the symptoms of a stroke as quickly as possible. Early detection and treatment
Stroke symptoms can vary widely between individuals. However, many people will experience a few common signs of stroke, including:
- drooping of the mouth, eye, or one side of the face
- altered facial expressions
- garbled or slurred speech
- numbness or weakness in one arm
- vision changes
- extremely painful headache
A stroke is a medical emergency, a person should call 911 or go to the nearest emergency room if someone is experiencing stroke symptoms.
The length of time it takes to recover from a stroke depends on many factors. Receiving treatment soon after experiencing stroke symptoms
Experts suggest that people who have experienced a stroke may see the most improvement in the first 3 months of recovery after the stroke. After 6 months, their recovery and any improvements are likely to be slower.
However, some researchers have found that recovery can continue after 1.5 years following a stroke, although healthcare professionals have defined the crucial recovery window as within the first 3–6 months following a stroke.
The length of recovery time varies depending on the level of brain damage an individual has experienced during a stroke. People recovering from a stroke should speak with a doctor about individual recovery expectations.
Below are some common questions about stroke.
How long do mini-strokes last?
Mini-strokes can last for a few minutes but can continue for
What are the “FAST” signs of stroke?
The FAST acronym is a
- Face: A person’s face shows signs of drooping or numbness, and their smile may appear lopsided.
- Arms: One arm is weaker than the other — it may feel numb and drift downward when someone tries to raise both arms.
- Speech: A person’s speech becomes slurred or difficult to understand.
- Time: If a person is experiencing the symptoms above, it is time for someone to call 911.
How long does heat stroke last?
A stroke occurs when the blood supply to a part of the brain becomes disrupted or damaged. Depending on the type of stroke, it can last between a few minutes to several days.
After a stroke occurs, people recover within different timeframes that may take months or years, depending on the severity of the stroke. A healthcare professional can provide more information about individual recovery expectations.
Many preventive strategies may reduce a person’s risk of a stroke. Following a nutritious diet, exercising regularly, and avoiding smoking and alcohol can help. A person can speak with a doctor to learn more about ways to prevent stroke.
