Multiple Sclerosis (MS) – severe disease of the central nervous system, most often occurring among young active people (the first manifestations are usually noted at the age of 20 to 40 years), accompanied by a variety of neurological symptoms, leading to disability over several years.
To date, the only factor that is directly responsible for the development of the disease has not been determined. The most common hypothesis about the multifactorial nature of MS, i.e. the impact of external and genetic factors leading to the development of chronic inflammatory, demyelinating and neurodegenerative processes, which result in the destruction of myelin & ndash; A special layer that covers and protects the nerve fibers of the brain and spinal cord.
Signs and symptoms of MS can vary greatly depending on the location of damaged nerve fibers.
Among the symptoms of multiple sclerosis, the most common:
- Numbness or weakness of one or more limbs, usually on one side or the entire lower part of the body.
- Partial or complete loss of vision, usually in one eye, often accompanied by pain during eye movement (retrobulbar neuritis)
- Double or blur contours
- Tingling or pain in different parts of the body
- Electric shock sensations with certain head movements
- Coordination problems or unsteady gait
- Increased fatigue
Many patients with multiple sclerosis, especially in the initial stages of the disease, experience relapses of symptoms that are accompanied by periods of complete or partial remission (relapsing-remitting type of MS course).
A few years after the onset of the disease, the type of MS in many cases turns into a secondary progressive (VP), which is characterized by a gradual deterioration of neurological functions and, as a consequence, an increase in disability.
