What causes a TIA to happen?

Plaques can decrease the blood flow through an artery or lead to the development of a clot.

What causes the stroke like symptoms of a TIA to disappear?

A transient ischemic attack (TIA) happens when blood flow to part of the brain is blocked or reduced, often by a blood clot. After a short time, blood flows again and the symptoms go away. With a stroke, the blood flow stays blocked, and the brain has permanent damage.

• Emotional symptoms (such as irritability or anxiety).
• Brain fog, trouble concentrating, and word-finding struggles.
• Visual difficulties.
• Mildly slurred speech.

Are TIA hereditary?

The risk factors for transient ischemic attack and stroke are identical. Some are purely hereditary. This includes family history, race, and gender. A combination of genetic differences and access to health care makes minorities more likely to suffer a TIA or stroke than whites.

Are TIAs serious?

TIAs look like strokes in terms of signs and symptoms, but they are temporary. In other words, they leave no lasting brain damage or residual symptoms. However, they serve as a warning sign that a person is at higher risk of a major stroke and should seek immediate medical attention.

Like a stroke, a TIA is caused by a blockage cutting off the blood supply to part of your brain. The only difference when you have a TIA is that the blockage is temporary – it either dissolves on its own or moves, so that the blood supply returns to normal and your symptoms disappear.

When to see a doctor for a TIA?

If you think you have had a TIA some time in the past and have not yet sought medical attention, see your GP urgently. Some of these symptoms can be caused by other things such as low blood sugar, a migraine, an inner ear problem or a seizure. However, you cannot be sure of the cause until your symptoms are investigated by a doctor.
