So this is an interesting post about Stimulus Sensitive seizures also known as Reflex Seizures.
The major stimuli precipitating these seizures are Sensory in nature but as there is no known "Reflex" to cause such seizures they are better termed as Stimulus Sensitive Seizures!
So in order to study these seizures Japanese children were exposed to Pokémon cartoon that induced seizures, surprisingly out of all the children who had an episode of seizure only 24% had a history of spontaneous seizures. These children had the Photosensitive type of Stimulus Sensitive seizures.
Photosensitive or pattern-induced seizures as experimented in the Japanese kids are, well-recognized and stimulated by bright or flashing lights (TV, video games, discotheques, concert light shows) or by patterns (lines on the road while traveling). These may occur 1 in 4,000 people in age group of 5-25yr but are outgrown in their 30s.
For patients with isolated photosensitive or pattern-induced seizures, avoidance or modification of stimuli is the initial approach in the form of wearing blue or polarized sunglasses, avoiding highcontrast flashing-light video games,
avoiding discotheques, watching TV in a well-lit room at a distance of >8 feet, and covering 1 eye when in a provocative situation.
Well generally it is observed that many patients with epilepsy can identify precipitating or provoking events that predispose them to having a seizure.
Common events include :
lack of sleep
In another group, patients have seizures in response to a very specific, identifiable sensory stimulus or activity.
These stimuli may be :
External :(light, patterns, music, brushing teeth)
Internal :(math, reading, thinking, self-induced).
The manifestation of these seizures can be either:
One common pattern is photomyoclonic seizures characterized by forehead muscle twitching or repetitive eye opening or closing.
So till the next time you play Pokèmon Go or you see Pikachu in action do remember about Stimulus Sensitive Seizures! ;)
Hope this was informative!
