General practitioner's office

In your general practitioner's office, you are seeing a 65-year-old man with a history of atrial fibrillation and arterial hypertension, who is fully independent.
A year ago, he experienced a transient ischemic attack (TIA), with a temporary (approximately 30-minute) speech disturbance, followed by a full recovery of neurological findings.
During the consultation, you notice a sudden onset of neurological deficits (aphasia, leftward deviation of the eyes, and right-sided hemiparesis). You perform a basic neurological exam, secure vital functions, and measure blood pressure.
