Abstract
Background
Multiple sclerosis (MS) is a neurological disorder with demyelination of neuronal matter, especially of white matter, with multiple episodes occurring temporally. It has been associated with multiple neurological and psychiatric sequelae. Depression and other affective symptoms are commonly associated with MS. Previous research has also suggested that psychotic symptoms may co-occur with MS as well.
Material and Methods
A case report was prepared on the patient admitted to the inpatient unit. Subsequently, a systematic literature review of literature was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) model on three databases. Search terms included (MS OR multiple sclerosis) AND (Psychosis OR schizophrenia OR schizoaffective disorder OR psychotic OR hallucination OR delusion).
Results
The literature review led to an initial discovery of 2711 hits on PubMed, 1276 hits on PsycINFO, and 5429 hits on Embase. Some patients were diagnosed with MS at an earlier age with a later onset of psychosis, while some were initially diagnosed with psychosis (or schizophrenia) first and subsequently with MS. Psychotic symptoms observed included persecutory delusions, lack of insight, delusions of reference, auditory hallucinations, grandiose delusions, and passivity. The commonly prescribed antipsychotics included risperidone, olanzapine, quetiapine, and aripiprazole. The presence of co-occurring psychosis in MS patients underscores the need for a comprehensive evaluation of symptoms.
Conclusion
This case highlights the importance of conducting a magnetic resonance imaging (MRI) brain not only for initial onset psychosis but also for any sudden changes in patients who have had a relatively stable course. Moreover, psychosis can affect treatment adherence in MS, making it all the more critical to identify and manage it promptly.
