Multiple sclerosis: current knowledge and future outlook.

Area of Science:

• Neurology
• Immunology

Background:

• Multiple sclerosis (MS) is a chronic central nervous system inflammatory disease.
• Unknown etiology involving environmental and genetic factors.
• Advances in understanding pathophysiology drive new therapies.

Purpose of the Study:

• Provide an overview of current MS knowledge.
• Highlight latest diagnostic criteria.
• Discuss current and upcoming treatment options.

Main Methods:

• Review of current literature on MS diagnosis and treatment.
• Emphasis on McDonald criteria for diagnosis.
• Categorization of therapies into relapse, disease-modifying, and symptomatic.

Main Results:

• Diagnosis relies on updated McDonald criteria.
• Relapse treatment often involves intravenous methylprednisolone.
• First-line therapies include interferon-β, glatiramer acetate, or teriflunomide.

Conclusions:

• MS treatment landscape is rapidly evolving.
• Escalation therapies offer higher potency but carry risks.
• Personalized treatment selection is a future challenge.
