What are the symptoms of a stroke?
Posted by Ian Everett on Monday Dec 16, 2019 Under UncategorizedWhat are the symptoms of a stroke?
The occurrence of stroke can usually be identified by the onset of the following symptoms:
- F – face. Part of the person’s face starts to droop, making it difficult for them to smile.
- A – arms. The person is unable to fully lift their arms.
- S – speech. The person has difficulties with speech, which becomes slurred.
- T – time. It is time to call 999. A person displaying these symptoms must immediately be taken to an emergency department for treatment.
A person experiencing a stroke might also have a sudden headache, confusion, dizziness, problems with communicating or problems with their vision.
How does a stroke lead to brain injury?
The brain relies on a rich supply of oxygen to keep brain cells working; this is supplied by an intricate network of blood vessels that pump oxygen-rich blood around the brain. When this blood flow is disrupted by either a blood clot or a burst blood vessel, the brain cells are starved of oxygen and they begin to die. This results in brain injury.
What is a transient ischaemic attach (TIA)?
These are mini strokes that can occur in the brain. A TIA occurs when there is a temporary disruption to the blood supply to the brain due to a blocked blood vessel. The symptoms of a TIA are the same as a stroke, but they only last for a few minutes or hours. However, medical attention should always be sought as soon as these symptoms are recognised, as they can be an indication of a stroke occurring. Even if the symptoms of a TIA improve or disappear by the time an ambulance arrives, it may still be necessary to carry out a medical assessment, as TIAs indicate a risk of experiencing a stroke in the future.
What are the causes of stroke?
Sometimes the disruption to the blood supply to the brain can be due to natural causes, such as weakening of blood vessels over time or a genetic condition that increases the risk of experiencing a stroke.
However, there are some factors that can increase the risk of experiencing a stroke; these include:
- Smoking
- Drinking too much alcohol
- Being overweight
- Not exercising enough
- Eating too much food
There are some blood-related medical conditions that also increase the risk of having a stroke. These include:
- Diabetes
- High blood pressure
- Atrial fibrillation
- High cholestrol
Receiving appropriate treatment for any medical condition can reduce the chance of experiencing a stroke.
