PNES episodes can be difficult to distinguish from epileptic seizures without the use of long-term video EEG monitoring.Some characteristics which may distinguish PNES from epileptic seizures include gradual onset, out-of-phase limb movement (in which left and right extremities jerk asynchronously or in opposite directions, as opposed to rhythmically and simultaneously as in epileptic seizures ...
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."
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]
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.
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.
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).
This rare epilepsy has a wide age range of presentation (from the first year of life through the early teens). This epilepsy is characterized by absence seizures concurrent with myoclonic jerks, typically occurring several times daily. The genetics of this disorder have not been delineated. Seizures from this disorder often cease within 5 years.
