Which disorder is characterized by acquired aphasia and multifocal epileptiform abnormalities?

• A. West syndrome
• B. Landau Kleffner syndrome
• C. Lennox Gastaut syndrome
• D. Juvenile myoclonic epilepsy

Answer: (B)

Landau Kleffner syndrome is defined by the combination of acquired aphasia, where children lose previously acquired language skills, and multifocal epileptiform abnormalities during electroencephalographic (EEG) monitoring. This condition typically presents in children between the ages of 3 and 7 and is associated with abnormal electrical activity in the brain, manifesting as epileptic seizures and cognitive impairments, particularly affecting language comprehension and expression. The impairment in language abilities is typically notable, and this syndrome can be mistaken for autism or other developmental disorders due to the language regression. However, the presence of epileptiform activity on EEG, characterized by spikes and sharp waves in multiple regions of the brain, is a key diagnostic feature that distinguishes it from other disorders like West syndrome, Lennox Gastaut syndrome, and Juvenile myoclonic epilepsy, which have different presentations and effects.
