Hystero-epilepsy is a historical term that refers to a condition described by 19th-century French neurologist Jean-Martin Charcot [29] where people with neuroses "acquired" symptoms resembling seizures as a result of being treated on the same ward as people who genuinely had epilepsy.
Confusional arousals as well as arousal parasomnias in general must be distinguished from epileptic seizure on the basis of clinical and electroencephalographic features (see electroencephalography). [ 3 ]
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.
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 seizures).
A provoked (or an un-provoked, or an idiopathic) seizure must generally occur twice before a person is diagnosed with epilepsy. When used on its own, the term seizure usually refers to an epileptic seizure. The lay use of this word can also include sudden attacks of illness, loss of control, spasm or stroke. [4]
Transient amnesia can be the principal manifestation of epilepsy. This diagnosis, however, is "seldom suspected by clinicians and remains controversial". [4] TEA is "almost always misdiagnosed" according to a leading authority. [9] In the largest study to date (2007) "Epilepsy was the initial specialist diagnosis in only 12 of 50 cases."
Thereafter, the seizure may or may not evolve into loss of consciousness and a generalized tonic–clonic seizure. [2] [1] In contrast to the auras in ecstatic seizures, most auras of seizures generally are unpleasant, including feelings of anxiety and fear (60%) as well as depression, while positive feelings are only rarely reported. [1]
The definition of epilepsy requires the occurrence of at least one epileptic seizure." [12] [107] It is, therefore, possible to outgrow epilepsy or to undergo treatment that causes epilepsy to be resolved, but with no guarantee that it will not return. In the definition, epilepsy is now called a disease, rather than a disorder.
