Which neurological symptoms may indicate a transient ischaemic attack in cardiovascular disease?

• A. Visual disturbances alone indicate an immediate stop to the test.
• B. Headache is the primary concern.
• C. Visual disturbances or speech difficulties may indicate a transient ischaemic attack.
• D. Numbness in the feet.

Answer: (C)

These questions test recognizing focal neurological symptoms that point to a transient ischemic event in the brain. Visual disturbances and speech difficulties reflect transient ischemia in brain regions responsible for vision and language. When blood flow is briefly reduced, these specific functions can be affected and then recover, which is exactly what a transient ischemic attack looks like. In cardiovascular disease, TIAs are warning signs of possible stroke, so any sudden visual changes or trouble with speaking require urgent evaluation and management to reduce future risk. Headache alone isn’t a defining sign of a TIA—it can be caused by many other conditions, so it doesn’t specifically indicate a transient cerebral ischemia. Numbness in the feet is not typical for TIAs, which usually produce focal deficits in the face, arm, or leg on one side, or specific functions like vision or speech, rather than isolated numbness in the feet.
