Clinical Reasoning: An 11-year-old boy with language disorder and epilepsy

An 11-year-old boy with recurrent seizure attacks and expressive language disorder was referred to our clinic. His initial attack was at the age of 2, when he had a sudden facial twitching, followed by a generalized tonic convulsion together with loss of consciousness, lasting a few minutes. The episode recurred every few months thereafter. In addition, he could never utter any verbal language, although he could understand what others said, as well as follow their commands.
