Seizures originate in the occipital lobe and account for 5 to 10 percent of all epileptic seizure types. Generally, this type of epilepsy can have an onset anywhere from 1–17 years old in children, but the patient prognosis is good. Since the event is located in the occipital lobe, symptoms may occur spontaneously and include visual stimuli.
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.
In adults, after 6 months of being seizure-free after a first seizure, the risk of a subsequent seizure in the next year is less than 20% regardless of treatment. [67] Those who have a seizure that is provoked have a low risk of re-occurrence, but have a higher risk of death compared to those with epilepsy. [68]
Abdominal epilepsy is marked by GI symptoms such as abdominal pain followed by uncontrollable vomiting, usually preceded by lethargy. Lethargy and confusion is the most common neurological symptoms associated with abdominal epilepsy. Other symptoms include generalized tonic-clonic seizures followed by sleep, and unresponsiveness.
Temporal lobe epilepsy is the most common type of focal onset epilepsy among adults. [1] Seizure symptoms and behavior distinguish seizures arising from the mesial temporal lobe from seizures arising from the lateral (neocortical) temporal lobe. [2] Memory and psychiatric comorbidities may occur.
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]
