Self assessment exercises in general practice.

3. A 23 year old soldier attends your surgery with a colleague. That morning he had been watching television when he had suffered an episode of collapse with loss of consciousness and he is unable to recall anything else until he remembers coming around lying on the floor. His colleague, who witnessed the episode, describes what sounds like a generalised tonic-clonic convulsion. There was no preceding aura, and no associated injuries, although he had been incontinent of urine. Afterwards, he was confused and dazed for about an hour, but by the time you see him he says he feels back to normal.
