Riding roller coasters may increase the risk of developing potentially harmful blood clots on the brain's surface.
The Neurological center reported a case of 25 year old healthy male who developed blood clots on the brains surface, known as subdural haematomas, after riding several roller coasters.The symptoms of blood clot includes difficulty in walking, vomiting, changes in mental abilities seizure and sometimes causes death. It usually occurs in older men who are alcoholics, diabetic or hypertensive. They can also be caused by head trauma, falling to a sitting position or strain from heavy lifting.
Although it is rare for people to develop subdural haematomas after riding roller coasters, it can happen, says Dr. Ishano Kyuorite of Japan. He further added that Giant roller coasters which are higher and faster may be more dangerous.
The subdural haematomas are caused by the up-and-down, back-and-forth motions of the roller coaster or the acceleration force which ruptures the veins on the surface of the brain. Surgery is the treatment of choice.
