A 62-year-old male patient exhibits weakness on one side and slurred speech that subsides within a short time. What is likely the cause?

The symptoms described in the scenario—weakness on one side of the body and slurred speech that resolves quickly—are characteristic of a transient ischemic attack (TIA). A TIA occurs when there is a temporary disruption of blood flow to the brain, leading to brief neurological symptoms. These symptoms can mimic those of a stroke but typically resolve within a few minutes to hours, with no lasting damage.

In this case, the transient nature of the weakness and speech difficulties strongly aligns with the definition of a TIA, making it the most appropriate diagnosis. TIAs serve as critical warnings for potential future strokes, emphasizing the importance of medical evaluation and management following such episodes.

Other options, while they present serious conditions, do not fit the timeframe or recovery pattern illustrated. For instance, a subdural hematoma usually leads to progressive neurological decline rather than quick resolution. Status epilepticus involves prolonged seizure activity, which would not typically present with transient weakness and slurred speech. Acute coronary syndrome primarily impacts heart function, and while it may cause symptoms like chest pain or shortness of breath, it does not account for unilateral weakness or speech issues specifically.
