Seizure trigger

There are many causes of seizures. The factors that lead to a seizure are often complex and it may not be possible to determine what causes a particular seizure, what causes it to happen at a particular time, or how often seizures occur.

Ancient Greeks thought pressing down onto possible causes of epilepsy, naturally found understanding of seizures within a divine origin and cause.

Malnutrition and overnutrition may increase the risk of seizures. Examples include the following:

Folic acid in large amounts was considered to potentially counteract the antiseizure effects of antiepileptic drugs and increase the seizure frequency in some children, although that concern is no longer held by epileptologists.

Those with various medical conditions may suffer seizures as one of their symptoms. These include:

Other conditions have been associated with lower seizure thresholds and/or increased likelihood of seizure comorbidity (but not necessarily with seizure induction). Examples include depression, psychosis, obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), and autism, among many others.

Seizures may occur as an adverse effect of certain drugs. These include:

Use of certain recreational drugs may lead to seizures in some, especially when used in high doses or for extended periods. These include amphetamines (such as amphetamine, methamphetamine, MDMA ("ecstasy"), and mephedrone), cocaine, methylphenidate, psilocybin, psilocin, and GHB.
