Abstract:
The authors examined the records of 149 children with language regression (LR) who had overnight EEG monitoring. Children with isolated LR had a higher frequency of epileptiform abnormalities (60%) than those with LR in the context of autistic regression (31%, p = 0.002) and also a higher rate of clinical seizures (33% vs 8%, p < 0.001). EEG abnormalities in the LR only group were also more prominent. This suggests two subtypes of language regression.

Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...
Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
