Acute Psychosis as the Initial Presentation of MS: A Case Report

Area of Science:

• Neuroimmunology
• Psychiatry
• Neurology

Background:

• Multiple sclerosis (MS) is frequently linked with psychiatric disorders, either as a disease manifestation or treatment side effect.
• Some MS patients present initially with psychiatric symptoms, including infrequently reported atypical psychosis.
• Acute psychosis with stress-like features is a rare initial presentation in MS.

Observation:

• This case report details an individual presenting with acute psychosis symptoms typically associated with stress.
• The patient's presentation mimicked functional psychosis, prompting a need for careful differential diagnosis.
• The underlying cause was identified as an acute onset of demyelinating disease.

Findings:

• Acute demyelinating disease can present with the clinical phenotype of acute psychosis associated with stress.
• This presentation is rare but underscores the importance of considering neurological conditions in psychiatric emergencies.
• Early recognition is crucial for appropriate management and treatment.

Implications:

• Clinicians should consider demyelinating diseases like MS in the differential diagnosis of acute psychosis, especially when stress-related features are present.
• This case emphasizes the diverse neurological manifestations of MS and the importance of a comprehensive diagnostic approach.
• Prompt diagnosis and treatment of MS can prevent long-term neurological damage and improve patient outcomes.
