Psychosis in Huntington´s Disease. a rare and Under-Investigated Psychiatric Manifestation

Introduction : Psychotic symptoms are among the least prevalent and under-investigated psychiatric manifestations (PM) of Huntington's disease (HD). Case report : We herein report a case of a 31-year-old male patient who presented PM with a predominance of negative symptoms, without any significant abnormal movement. HD was diagnosed based on positive DNA analysis and family history. HD imposes longitudinal follow-up through a multidisciplinary approach in order to improve the quality of life and prognosis. Conclusion : This case report highlights the importance of comprehending the PM in the initial presentation of HD so that the diagnosis is not delayed until the onset of motor symptoms.
