Multiple Sclerosis and psychosis: A case report.

Psychiatric symptoms resulting from Multiple Sclerosis (MS) itself or its treatment are well known. However, the relationship between psychotic episodes and Multiple Sclerosis remains debated. In this paper, we present the case of a woman who developed a chronic psychotic disorder a few months after the onset of MS. We describe the process which led us to make the diagnosis of Psychotic Disorder due to Medical Condition (Multiple Sclerosis). Because her criminal charges brought significant attention to her case, we also address the difficulty in treating a neurological condition with psychiatric features within the forensic context. Moreover, one of the main concerns of the patient was that Lyme Disease was the correct diagnosis as opposed to MS. We also report the difficulty of treating and initiating successful follow-up for a patient whose paranoia is enabled by the opinions of certain health advocacy groups.
