A Rare Case of Psychosis in Ushers’s Syndrome in Absence of Hallucinations

Usher syndrome is a clinically and genetically heterogeneous syndrome leading to hearing and vision loss. Three types of Ushers syndrome have been described based on severity of hearing loss and presence or absence of vestibular symptoms. Although several mental disorders have been seen to be associated with Ushers syndrome, the awareness of the same is lacking in the medical community. There have been only few case reports of Ushers syndrome and psychosis, with visual and auditory hallucinations being the predominant feature in these cases. Hereby the author discusses a unique case of ushers syndrome and psychosis in absence of any hallucinations.
