Disease characteristics

Autosomal dominant epilepsy with auditory features (ADEAF) is a focal epilepsy syndrome with auditory symptoms and/or receptive aphasia as prominent ictal manifestations. The most common auditory symptoms are simple unformed sounds including humming, buzzing, or ringing; less common forms are distortions (e.g., volume changes) or complex sounds (e.g., specific songs or voices). Ictal receptive aphasia consists of a sudden onset of inability to understand language in the absence of general confusion. Less commonly, other ictal symptoms may occur, including sensory symptoms (visual, olfactory, vertiginous, or cephalic) or motor, psychic, and autonomic symptoms. Age at onset is usually in adolescence or early adulthood (age 10-30 years). The clinical course of ADEAF is benign. Seizures are usually well controlled after initiation of medical therapy. [from GeneReviews]

Additional descriptions

From OMIM
Autosomal dominant lateral temporal lobe epilepsy is a specific form of temporal lobe epilepsy characterized by partial seizures originating from the temporal lobe. Seizures are usually accompanied by sensory symptoms, most often auditory in nature (summary by Winawer et al., 2000). Genetic Heterogeneity of Temporal Lobe Epilepsy See also ETL2 (608096), which maps to chromosome 12q; ETL3 (611630), which maps to chromosome 4q; ETL4 (611631), which maps to chromosome 9q; ETL5 (614417), caused by mutation in the CPA6 gene (609562) on chromosome 8q13; ETL6 (615697), which maps to chromosome 3q25-q26; ETL7 (616436), caused by mutation in the RELN gene (600514) on chromosome 7q22; and ETL8 (616461), caused by mutation in the GAL gene (137035) on chromosome 11q13.  http://www.omim.org/entry/600512
From MedlinePlus Genetics
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.  https://medlineplus.gov/genetics/condition/autosomal-dominant-epilepsy-with-auditory-features
