## Definition

Stands for transient ischemic attack. A temporary blockage of blood to the brain that causes stroke-like symptoms for a short time. It is often called a 'mini-stroke' and serves as a serious warning sign.

For teachers: Abbreviation for transient ischemic attack. A brief episode of neurological dysfunction caused by focal brain, spinal cord, or retinal ischemia, without acute infarction. Often referred to as a 'mini-stroke', it typically resolves within 24 hours.

## Examples

- He went to the hospital after experiencing a TIA.
- Doctors monitored the patient closely after a TIA to prevent a more severe stroke from occurring later.
- While the symptoms of a TIA are transient and leave no permanent damage, they necessitate immediate clinical evaluation to mitigate the high risk of a subsequent major cerebrovascular accident.

## Usage notes

- Usually used with the indefinite article 'a' (pronounced as individual letters: T-I-A).
