Abstract	Aphasic epilepsy is the term which means the acute onset of aphasia without the consciousness disturbance. Aphasic epilepsy of adult-onset is called aphasic status epilepticus, and that of child-onset is Landau-Kleffner syndrome. Typically, electroencephalography (EEG) revealed the consistent epileptic discharges at dominant hemisphere, mainly at frontotemporal regions. But, there are some cases without any abnormal findings in conventional EEG. Such cases are often misdiagnosed with psychosomatic diseases or hearing difficulties because the patients cannot respond their name calling correctly and spontaneously. In such cases, EEG recording during sleep and/or continuous video-EEG monitoring for at least 24 hours is recommended. Anticonvulsant medications can readily control clinical seizures. It is important to closely interview the state and to correctly examine the neuropsychological findings during the attacks.
