[Clinical forms and pathophysiology of multiple sclerosis].

Area of Science:

• Neuroimmunology
• Neuroscience
• Pathophysiology

Background:

• Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease of the central nervous system (CNS).
• The exact triggers for MS remain unknown, but genetic and environmental factors are implicated.
• Four distinct clinical forms of MS are recognized.

Purpose of the Study:

• To elucidate the clinical forms and underlying pathophysiology of multiple sclerosis.
• To highlight the role of inflammatory and autoimmune processes in MS pathogenesis.

Main Methods:

• Review of existing literature on MS clinical presentations.
• Analysis of cellular and molecular mechanisms involved in MS pathophysiology.
• Correlation of pathophysiological processes with clinical disease progression.

Main Results:

• Inflammatory processes in the CNS lead to myelin degradation, axonal damage, and neuronal loss in MS patients.
• Autoimmune cellular mechanisms are central to the disease's progression.
• Disease progression correlates with the activity of these autoimmune pathways.

Conclusions:

• Multiple sclerosis involves complex inflammatory and autoimmune processes targeting the CNS.
• Understanding these mechanisms is crucial for managing disease progression and exploring therapeutic strategies.
