A transient ischemic attack (TIA) is a condition related to strokes that signifies a raised risk of a stroke in the future.
It happens when blood supply to the brain is temporarily interrupted.
However, it still requires immediate medical attention.
According to the American Association of Neurological Surgeons (AANS), common symptoms of a TIA often resolve themselves in up to 20 minutes.

Two such signs that affect the leg include loss of strength or numbness.
It explains: “This (a TIA) is a warning sign of a possible future stroke and is treated as a neurological emergency.
"Common temporary symptoms include difficulty speaking or understanding others, loss or blurring of vision in one eye and loss of strength or numbness in an arm or leg.
“Usually these symptoms resolve in less than 10 to 20 minutes and almost always within one hour."
The AANS urges people to seek medical help “immediately” if they notice these signs.
In terms of a full stroke, there are two main types: ischaemic and haemorrhagic.
Ischaemic strokes are far more common, accounting for around 85 percent of cases.
They occur when the blood supply is stopped because of a blood clot.

Haemorrhagic strokes, on the other hand, happen when a weakened blood vessel supplying the brain bursts.
There are certain medical conditions that can increase your risk of a stroke of TIA.
These include having:
- High blood pressure (hypertension)
- High cholesterol
- Irregular heart beats (atrial fibrillation)
- Diabetes.
If you believe someone is having a stroke the NHS says you should call 999 straight away.
