A seizure is a sudden change in behavior, movement or consciousness due to abnormal electrical activity in the brain. [3] [6] Seizures can look different in different people.. It can be uncontrolled shaking of the whole body (tonic-clonic seizures) or a person spacing out for a few seconds (absence seizure
Although no effective device that can predict seizures is available, the science behind seizure prediction and ability to deliver such a tool has made progress. Kindling , where repeated exposures to events that could cause seizures eventually causes seizures more easily, has been used to create animal models of epilepsy. [ 233 ]
Epileptic auras are subjective sensory or psychic phenomena due to a focal seizure, i.e. a seizure that originates from that area of the brain responsible for the function which then expresses itself with the symptoms of the aura. It is important because it makes it clear where the alteration causing the seizure is located.
Generalized epilepsy is a form of epilepsy characterised by generalised seizures with no apparent cause. [1] Generalized seizures, as opposed to focal seizures, are a type of seizure that impairs consciousness and distorts the electrical activity of the whole or a larger portion of the brain (which can be seen, for example, on electroencephalography, EEG).
The 2018 Pixar film Incredibles 2 contains scenes with flashing lights starting about an hour into the film, in which a villain called the Screenslaver hypnotizes other characters.

[2] [3] The effects are similar to seizures caused by epilepsy (in particular photosensitive epilepsy), but are not restricted to people with histories of epilepsy. This phenomenon has been observed during helicopter flight; a Dr. Bucha identified the phenomenon in the 1950s when called upon to investigate a series of similar and unexplained ...
