Anamnesis

A 58-year-old retired bus driver reports a headache that exploded to full severity in what he described as a single instant, with no gradual build-up whatsoever. He was gardening at the time and had to sit down immediately. Using a timer, he confirms the pain had completely resolved within eight minutes. He says he has never experienced anything like this before, and there was no vomiting, no visual change, and no weakness of the limbs during or after the event. He does not smoke or drink to excess.

Report this case — e.g. suspected re-identification risk.
