Auditory symptoms in cerebrovascular disease

Based on clinical scientific notes in Neurology Lee et al., 2008 70: 2413-2415.

Hyperacusis usually occurs in peripheral labyrinthine dysfunction, but is reported in depression, migraine, and certain infectious diseases. Paracusia (altered sensation of timbre, pitch, or loudness) and palinacousis (perseveration of auditory image) after MGB hemorrhage. Auditory hallucination is reported with pontine hemorrhage. Bilateral hyperacusis is due to caudal tectal hemorrhage. This paper has unilateral hyperacusis due to contralateral pontine hemorrhage. Authors suggest hypersensitization and relationship to ipsilateral sensory discomfort, and an association with complex regional pain syndrome patients, who may have same symptom. See references.
