Patient at risk: sensitivity to flickering lights or geometric patterns
Factors associated with increased risk for seizure while playing a video game:
(1) playing when tired or sleep deprived
(2) playing at certain times of the day or on certain days
(3) hyperventilation
(4) game features (bright lights, flicker rate, change in patterns, etc)
