A gelastic seizure, also known as "gelastic epilepsy", is a rare type of seizure that involves a sudden burst of energy, usually in the form of laughing. [1] This syndrome usually occurs for no obvious reason and is uncontrollable. It is slightly more common in males than females.
The charity has received international media coverage on a number of occasions due to its work in highlighting bad practice in online videos in relation to photosensitive epilepsy. In 2007, it claimed that 30 people had seizures as a result of a segment of animated footage commissioned by the organising committee of the London 2012 Summer ...
Epilepsy is a group of non-communicable neurological disorders characterized by recurrent epileptic seizures. [10] An epileptic seizure is the clinical manifestation of an abnormal, excessive, and synchronized electrical discharge in the neurons. [1]
Epilepsy is a neuronal disorder with multifactorial manifestations. [8] It is a noncontagious illness and is usually associated with sudden attacks [ 9 ] of seizures, which are an immediate and initial anomaly in the electrical activity of the brain that disrupts part or all of the body. [ 8 ]
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.
Strokes, brain bleeds, and traumatic brain injury can all also lead to epilepsy if seizures re-occur. If the first seizure occurs more than 7 days following a stroke, there is a higher chance of the person developing epilepsy. [27] Post-stroke epilepsy accounts for 30%-50% of new epilepsy cases. [27]
A simple partial seizure may go unnoticed by others or shrugged off by the patient as merely a "funny turn." Focal aware seizures usually start suddenly and are very brief, typically lasting 60 to 120 seconds. [10] [failed verification] Some common symptoms of a simple partial seizure are: [7] [failed verification] preserved consciousness
In adults, the figures are similar, with one study reporting a 26% rate of misdiagnosis. [ 7 ] Differentiation of a non-epileptic attack from an epileptic seizure includes the patient keeping their eyes closed and rarely causing themselves harm (both more common in non-epileptic attacks)
