Landau–Kleffner syndrome (LKS), also called infantile acquired aphasia, acquired epileptic aphasia, [1] or aphasia with convulsive disorder, is a rare neurological syndrome that develops during childhood. [2] It is named after William Landau and Frank Kleffner, who characterized it in 1957 with a diagnosis of six children. [3] [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.
When seizures affect areas other than the motor cortex, other transient neurological deficits can take place. These include sensory changes if the sensory cortex is involved by the seizure, visual field defects if the occipital lobe is involved, and aphasia if speech, comprehension or conducting fibers are involved.

Status epilepticus (SE), or status seizure, is a medical condition with abnormally prolonged seizures.It can have long-term consequences, [3] manifesting as a single seizure lasting more than a defined time (time point 1), or 2 or more seizures over the same period without the person returning to normal between them.
Additional seizure types appear, most often these are myoclonic, atypical absence, and focal seizures. [9] Seizures persist despite treatment with medication, however several medications including valproic acid, stiripentol, clobazam, fenfluramine and pharmaceutical grade cannabidiol are often helpful to decrease seizure burden. Development is ...
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).
After classifying seizure types, the second part is the classification of the epilepsy type. Classification of the epilepsy types assumes that the patient has epilepsy as defined by one of the three condition as detailed above in the diagnosis section. Epilepsy types just as seizure types include focal, generalized, unknown, and another ...
