Overview
Multiple sclerosis is an inflammatory demyelinating disorder of the central nervous system that can produce neurological deficits affecting different functional systems.
Clinical manifestations may involve vision, sensation, strength, coordination, balance, and other neurological functions.
A key concept in multiple sclerosis is the occurrence of neurological dysfunction affecting different anatomical sites and/or occurring at different times.
Clinical Features
Patients may present with episodes of optic neuritis, sensory disturbance, limb weakness, diplopia, ataxia, or other focal neurological deficits.
Symptoms may partially or completely improve before another neurological episode develops.
Investigation
MRI of the brain and spinal cord is central to diagnosis and may demonstrate lesions characteristic of inflammatory demyelination.
Additional testing, including cerebrospinal fluid analysis, may provide supportive evidence in appropriate patients.
The diagnosis requires integration of the clinical history, examination, imaging findings, and appropriate exclusion of alternative diagnoses.
Management
Management includes treatment of acute relapses, disease-modifying therapy when appropriate, symptom management, and rehabilitation.
Treatment selection depends on disease activity, clinical phenotype, comorbidities, and patient-specific factors.
Clinical Pearls
Think about multiple sclerosis when neurological episodes suggest involvement of the central nervous system in different locations or at different times.
