New Headache in an Elderly Patient

A 79-year-old man presented to his GP with a new onset left-sided headache lasting for 6 weeks. The patient denied any history of trauma or falls, visual changes, or changes in gait or coordination. Following his GP review, he developed episodic sensory symptoms in his left-sided extremities; pins and needles and numbness starting in the left foot which then moved up his body, associated with some left arm and hand spasm (clenched left fist). These episodes lasted for up to 15 min and occurred approximately once a week. The patient was eventually admitted and reviewed by a neurologist.
