Autosomal dominant epilepsy with auditory features

Autosomal dominant epilepsy with auditory features (ADEAF) is an uncommon form of epilepsy that runs in families. People with this condition typically hear sounds (auditory features), such as buzzing, humming, or ringing, during seizures. Some people hear more complex sounds, like specific voices or music, or changes in the volume of sounds. Some people with ADEAF suddenly become unable to understand language before losing consciousness during a seizure. This inability to understand speech is known as receptive aphasia. Less commonly, seizures may cause visual hallucinations, a disturbance in the sense of smell, a feeling of dizziness or spinning (vertigo), or other symptoms that affect the senses.

Description

Autosomal dominant epilepsy with auditory features (ADEAF) is an uncommon form of epilepsy that runs in families. People with this condition typically hear sounds (auditory features), such as buzzing, humming, or ringing, during seizures. Some people hear more complex sounds, like specific voices or music, or changes in the volume of sounds. Some people with ADEAF suddenly become unable to understand language before losing consciousness during a seizure. This inability to understand speech is known as receptive aphasia. Less commonly, seizures may cause visual hallucinations, a disturbance in the sense of smell, a feeling of dizziness or spinning (vertigo), or other symptoms that affect the senses.

ADEAF is called a focal epilepsy because the seizures start in one part of the brain, rather than involving the entire brain from the beginning. Most people with ADEAF have focal aware seizures, which do not cause a loss of consciousness. These seizures are thought to begin in a part of the brain called the lateral temporal lobe. In some people, seizure activity may spread from the lateral temporal lobe to affect other regions of the brain. If seizure activity spreads to the entire brain, it causes a loss of consciousness, muscle stiffening, and rhythmic jerking. Episodes that begin as focal seizures and spread throughout the brain are known as secondarily generalized seizures.

Seizures associated with ADEAF usually begin in adolescence or young adulthood. They may be triggered by specific sounds, such as a ringing telephone or speech, but in most cases the seizures do not have any recognized triggers. In most affected people, seizures are infrequent and effectively controlled with medication.
