What photosensitive epilepsy

  2. 2. What Photosensitive Epilepsy?Sun Epilepsy disease of the brain, which causesrecurrent attacks (more than two). Seizure dueto abnormal electrical activity in the brain.
  3. 3. Epilepsy may be the result of:• Irregularity in the wiring of the brain• Umbalance of neurotransmitters (chemical messengers in the brain)• Combination of these factors• In photosensitive epilepsy, genetics also plays a role.
  4. 4. What Photosensitive Epilepsy?About one in 100 people in the U.S. haveepilepsy. About 3% to 5% of those people havephotosensitive epilepsy.
  5. 5. What Photosensitive Epilepsy?• Children and adolescents aged 7 to 19 are more likely to have photosensitive epilepsy.• Girls are affected by the condition more often than boys.• But boys tend to have more seizures.• Thats probably because they spend more time playing video games, a common seizure trigger.
  6. 6. Photosensitive Epilepsy Symptoms• Television – Television programs – London Olympics promotional film incident• Fluorescent lighting• Video games• Web design
  7. 7. Conclusion• The article I found goes into the general phenomenon of seizure self- induction, but does spend quite a bit of time on photosensitive epilepsy (PSE). Its a review, so there are plenty of references.• It first points out the prevalence of PSE, which occurs in between 2-5% of the population, and approximately 25% of those affected by the disorder are thought to self-stimulate.• The article supports the assertion on Wikipedia that developmentally challenged and "learning disabled" children are most prone to these self-inductive behaviors, but states that children of normal intelligence and higher may have developed strategies to avoid getting caught doing so during recorded sessions. It does not go into much depth regarding adults self-inducing, but tacitly assumes that adults of normal intelligence would be more likely to understand the harm that a seizure could bring them.• There is support for the notion that children with television induced seizures do try to seek out televisions for this self-stimulation behavior, but the article cautions that this compulsive behavior may be associated with the seizure activity itself, and not something the patients are consciously doing, many describe it as "irresistable."
  8. 8. The article lists a handful of reasons that are commonly thought to promote self-induction:• Compulsion - whether for pleasure seeking or as a result of seizure activity• Willful avoidance of stress or boredom• Hedonistic motivation - to experience an "aura"/trance or other pleasurable feelings• Sense of control - so they can have a "say" over when their seizures occur, and also so that they can reap the benefits of the refractory period• Attention seeking - being the "sick patient" for sympathetic family members• Self-treatment - the patient can give themselves a dose of "convulsive therapy" at will, if this gives them therapeutic relief of concomitant disorders
