Photosensitive Seizures (Seizures from Light Sensitivity) In a very small percentage of people, certain visual images (like fl ashing lights or patterns that may appear in video games) can lead to photosensitive seizures. These can also occur in people without any medical history of signs of epilepsy, etc., but who may have an undiagnosed medical condition that can cause these “photosensitive epileptic seizures” while watching video games. These types of seizures may present with a variety of symptoms, including dizziness, altered vision, twitching of the eye or face, jerking or shaking of the arms and legs, disorientation, confusion or temporary loss of consciousness. Seizures involving loss of consciousness or convulsions can also lead to injury from falling down or striking nearby objects. If you experience any of these symptoms, stop playing the game immediately and consult a physician. Parents should observe their children and ask them about the above symptoms. Children and teenagers are more likely than adults to experience these types of seizures. The risk of photosensitive epileptic seizures may be reduced by taking the following precautions: Sit farther from the screen; use a smaller screen; play in a well-lit room and avoid playing when you are drowsy or fatigued. Consult a physician before playing if you or any of your family members have a history of seizures or epilepsy.
