Rare onset symptoms in multiple sclerosis

Area of Science:

• Neurology
• Neuroimmunology
• Clinical Neuroscience

Background:

• Multiple sclerosis (MS) diagnosis can be challenging due to atypical presentations.
• Unusual onset symptoms may include pain, movement disorders, rare cranial nerve issues, and cognitive/psychiatric symptoms.

Purpose of the Study:

• To identify rare initial symptoms in multiple sclerosis patients.
• To offer diagnostic clues for earlier multiple sclerosis detection.

Main Methods:

• Retrospective analysis of 680 multiple sclerosis patients.
• Recorded onset symptoms included visual defects, cranial nerve involvement, paroxysmal symptoms, movement disorders, pain, and cognitive/psychiatric issues.

Main Results:

• Nineteen multiple sclerosis patients (13 female) exhibited unusual initial symptoms.
• Symptoms included rare cranial nerve involvement (5), pain syndromes (5), movement disorders (4), paroxysmal symptoms (2), and cognitive deficits (2).
• None were diagnosed with MS initially; diagnosis occurred months to years later.

Conclusions:

• Diverse central nervous system involvement causes a wide spectrum of rare initial multiple sclerosis manifestations.
• Early diagnosis of multiple sclerosis is vital for initiating disease-modifying treatment.
• Physicians must consider multiple sclerosis in patients presenting with these rare symptoms.
