Hyperacusis (or algiacusia) is a syndrome that makes everyday sounds become painful to the ear, the patient developing oversensitivity to sounds of certain tones or frequencies. Hyperacusis occurs because there is a loss of dynamic range of hearing. The most negative of having hyperacusis is that is so annoying that the patient is leaving your leisure activities. Thus, normal life and find it impossible to abandon habits like walking, talking on the phone, hanging out with friends and stop using appliances such as hair dryers or vacuum cleaners, not tolerate the sound. Hyperacusis may begin slowly or suddenly. Appears in patients with normal hearing or hearing slightly decreased (slight hearing loss), or in people with moderate hearing loss. Usually accompanied by tinnitus (ringing or noise in the ear). Causes of hearing loss may be the inner ear (damage to the cochlea, by irritability of the ciliated cells), auditory nerve, after a paralysis of the facial nerve, brainstem (rare case), the brain (central hyperacusis ) associated with migraine, fibromyalgia, related to the "CRPS pain" by irritability of the central auditory pathways or psychological in origin, among other causes. Treatment is usually with medication to relieve symptoms.
