Palinacousis
Palinacousis
Palinacousis (pronounced: pālənəˈkousis) is a rare neurological disorder characterized by the persistence or recurrence of auditory hallucinations after the cessation of an auditory stimulus. The term is derived from the Greek words "palin" meaning again and "acousis" meaning hearing.
Etymology
The term "Palinacousis" is derived from the Greek words "palin" which means again, and "acousis" which means hearing. It was first described in medical literature by Albert et al. in 1970.
Symptoms
The primary symptom of Palinacousis is the persistence or recurrence of sounds after the original sound has ceased. These sounds can be words, music, or non-speech sounds. The sounds are usually a repetition of the last sounds heard before the onset of silence or a change in the auditory environment.
Causes
The exact cause of Palinacousis is unknown. However, it is often associated with lesions in the temporal lobe of the brain, particularly the auditory cortex. It has also been linked to various conditions such as epilepsy, brain tumor, and stroke.
Diagnosis
Diagnosis of Palinacousis is primarily based on the patient's symptoms and medical history. Neurological examination and imaging studies such as MRI or CT scan may be used to identify any underlying conditions or brain lesions.
Treatment
Treatment for Palinacousis is primarily aimed at managing the underlying condition. This may involve medication, surgery, or other therapies depending on the specific condition. In some cases, no treatment is required as the symptoms may resolve on their own.
