Interictal epileptiform
Epilepsy waves recorded between seizures.
Description.
Interictal psychosis
Thought disorder, often with delusions, hallucinations or emotional changes that are temporarily related to the occurrence of seizures in people with epilepsy. Usually lasts 3-6 months.
Interstitial Radiosurgery
A type of radiosurgery which involves the temporary placement of radioactive seeds into the HH tissue. These radioactive seeds emit gamma radiation with minimal delivery of harmful radiation to normal surrounding structures.
Intractable
Difficult to alleviate, remedy, or cure; for example, intractable seizures are difficult to control with the usual antiepileptic drug therapy.
Intrahypothalamic (sessile)
A hypothalamic lesion which has a broad attachment, connects with the posterior hypothalamus, appear near the mamillary bodies and can distort the third ventricle.
Juvenile myoclonic epilepsy (JME)
A primary generalized epilepsy syndrome, usually beginning between ages 5 to 17 years, characterized by myoclonic (muscle-jerk) seizures and possibly also absence and tonic-clonic seizures; responds well to valproate.
Ketogenic diet
A high-fat, low-carbohydrate diet used to control seizures in some children with seizures, that are difficult to control with medications.
Left temporal seizure foci
Partial seizure dirsorder arising from the left temporal lobe.
Lennox-Gastaut syndrome
A disorder beginning in childhood, characterized by development delay or mental retardation, multiple seizure types that do not respond well to therapy, and slow spike-and-wave discharges on the EEG.
Limbic System
A group of structures in the brain that includes the hypothalamus, amygdala, and hippocampus. The limbic system plays an important part in regulation of human moods and emotions. Many psychiatric disorders are related to malfunctioning of the limbic system.
