Tonic–clonic seizures are the seizure type most commonly associated with epilepsy and seizures in general and the most common ...
A seizure is a paroxysmal episode of symptoms or altered behavior arising from abnormal excessive or synchronous brain neuronal activity. [5] A focal onset seizure arises from a biological neural network within one cerebral hemisphere, while a generalized onset seizure arises from within the cerebral hemispheres rapidly involving both hemispheres.

[1] Because epileptic seizures typically include convulsions, the term convulsion is often used as a synonym for seizure. [1] However, not all epileptic seizures result in convulsions, and not all ...
Frequency. ~10% of people (overall worldwide lifetime risk) [ 5 ][ 9 ] A seizure is a period of symptoms due to abnormally excessive or synchronous neuronal activity in the brain. [ 6 ] Outward effects vary from uncontrolled shaking movements involving much of the body with loss of consciousness ( tonic-clonic seizure ), to shaking movements ...
Conversion disorder (CD), or functional neurologic symptom disorder, is a diagnostic category used in some psychiatric classification systems.It is sometimes applied to patients who present with neurological symptoms, such as numbness, blindness, paralysis, or fits, which are not consistent with a well-established organic cause, which cause significant distress, and can be traced back to a ...

Childhood absence seizures account for 10% to 17% of all absence seizures. Onset is between 4 and 10 years and peaks at 5 to 7 years. It is more common in girls than in boys. [ 7]
