Roller-Coaster Headache

To the Editor: We report a case of subdural hematoma caused by riding on a roller coaster. A 64-year-old man presented to our neurology clinic with a 10-week history of headache. He was healthy, apart from hypertension controlled by triamterene (Dyazide) and hydrochlorothiazide. He had not previously had headaches. The headaches developed gradually after he began riding a roller coaster at an amusement park. The roller coaster, he reported, “swings people upside down as many as six times.” During the ride his head was enclosed within bars that kept him stable in a chair, and there was never direct trauma . . .
