Abstract

This article reviews recent research in the area of psychotic disorders in deaf psychiatric patients. Comparisons of the rates of psychotic disorders in the deaf and hearing populations suggest that psychotic disorders occur equally as often or even somewhat less often in the deaf population as in the hearing population. Consideration is given to the limitations of this small body of research, and recommendations for future research are provided. The contradictory literature on hallucinations in the deaf is also reviewed, and current theory about the manner in which hallucinations are manifested and experienced based on audiological history is presented. The challenges encountered by clinicians in accurately assessing symptoms of thought disorganization in deaf people are reviewed. Specifically, the etiology of deafness, language dysfluency, and the skill and training of American Sign Language interpreters are considered as factors impacting accurate diagnosis. Recommendations from the current literature are also provided.
