Severe persistent neuropsychological disorders sometimes develop in the course of a focal epilepsy of unknown origin in previously normal children. Very frequent bilateral focal or generalized discharges are often noted on the sleep EEG records of these patients with no evidence of clinical seizures. The relation between these paroxysms and the observed deterioration remains unclear. We report a child with a partial complex epilepsy and severe disturbances of language, cognition, and behavior acquired in the early years of development who was followed for 15 years. A correlation between the evolution of the striking EEG abnormalities during sleep and the neuropsychological disorders could be established retrospectively. The observed sequence of onset and recovery of the aphasia, the dementia, and the "psychotic" behavior makes a direct causal relation between the deficits quite unlikely. Rather it suggests an association of independent symptoms with a specific language disorder becoming manifest in the course of the evolution. This child shows many of the main characteristics of the syndromes of "acquired aphasia with convulsive disorder" (Landau-Kleffner syndrome) and "epilepsy with continuous spike waves during sleep." Both syndromes describe probably different facets of a similar underlying, still unexplained cerebral dysfunction.

Stuttering is characterized by involuntary syllabic repetitions and interruption in the smooth flow of speech. The exact cause of primary stuttering remains a matter of debate but a frontal dysfunction has been evoked. On the other hand, acquired stuttering is uncommon. We report a case of reflex epilepsy in which seizures were triggered by reading aloud or stressful conversation. Each paroxysmal event in left frontal region was associated clinically with a language disorder mimicking stuttering. Our observation suggests that reflex frontal focal epilepsy could be a putative etiology for acquired stuttering.

Self-limited focal epilepsy with centro-temporal spikes, also known as Rolandic epilepsy (RE), is a well-established focal epilepsy of childhood, characterized with language impairment. To investigate the relationship between language deficits and clinical parameters of self-limited focal epilepsies of childhood (SFEC), 21 patients with RE, 10 patients with childhood occipital epilepsy of Gastaut type (COE-G) (another SFEC that is not typically associated with language impairment), and 31 healthy controls were recruited. A broad panel of language tests also including narration sample was administered, and clinical features were documented. The language was significantly impaired in both RE and COE-G. Patients with COE-G showed worse scores than patients with RE in subtests measuring semantic functions. Clinical parameters were not associated with impaired language domains. Language impairment is experienced in different types of SFEC, emphasizing the broad representation of the language network. In SFEC, recent activity of epilepsy does not affect the severity of language dysfunction.
