3. Difficulty understanding others
Another subtle but important sign of a TIA is difficulty understanding spoken language, also known as receptive aphasia. You may hear others talking but suddenly find their words confusing or meaningless, even though your hearing is intact.
This happens when the part of the brain that processes language input is temporarily impaired due to reduced blood flow. Unlike slurred speech, this symptom affects comprehension rather than expression.
If you or someone else experiences this sudden confusion with language, it’s a red flag that warrants immediate medical attention.
4. Vision changes
Transient vision changes are a common but often overlooked symptom of a TIA. These may include:
- Temporary blindness in one eye (amaurosis fugax)
- Blurred or foggy vision
- Double vision or difficulty focusing
These symptoms occur because the small vessels supplying the visual centers in the brain or the optic nerve can become briefly blocked. Vision changes may last only a few minutes but signal cerebral ischemia, which requires urgent evaluation.
5. Dizziness or vertigo
A sudden onset of dizziness or vertigo—where you feel the room spinning or a loss of spatial orientation—can indicate that blood flow to the brainstem or cerebellum is compromised. This area controls balance and coordination.
While dizziness has many causes, when it appears suddenly and with other neurological signs, it may be a warning of a TIA affecting the posterior circulation of the brain. Because of the risk of progression to stroke, timely medical assessment is essential.
