Usher syndrome (or Hallgren syndrome) is an autosomal recessive genetic disorder characterized by sensorineural deafness, retinitis pigmentosa,and variable vestibular deficit; Usher syndrome type II is the most common form. Various neuropsychiatric disorders have been reported to occur in those with Usher syndrome, including schizophrenia-like disorder, atypical psychosis, recurrent depressive illness, neurotic disorder, and mental retardation; however, bipolar disorder is not common in those with Usher syndrome. Herein we describe a 30-year-old male with Usher syndrome type II that developed features indicative of a probable manic episode. The patient had complete remission of symptoms in response to treatment with olanzapine 20 mg d–1. In persons with dual sensory impairment there are inherent problems with assessment and diagnosis is difficult due to their limited communication abilities. The diagnosis of Usher syndrome depends heavily on behavioral observation and disturbances in vegetative functions
