Audiology and sleep disorders

Audiology is a division of science that studies hearing, balance, and related disorders. Audiology aims to determine whether someone can hear within the normal range, and if not, which portions of hearing (high, middle, or low frequencies) are affected, to what degree, and where the lesion causing the hearing loss is found (outer ear, middle ear, inner ear, auditory nerve and/or central nervous system). Auditory processing disorder (APD) is a group of disorders affecting the way the brain processes auditory information. Insomnia is a common complaint among patients with intractable dizziness ,restless leg syndrome (RLS) is another important sleep disorder. Reportedly, sleep apnoea is closely related to vestibular dysfunction and Meniere disease.
