What is sclerois?

Sclerosis refers to the hardening or thickening of tissue, often due to inflammation, scarring, or disease. It can affect various parts of the body, but is commonly associated with conditions like multiple sclerosis, where the immune system attacks the protective covering of nerve fibers. This can lead to neurological symptoms, including muscle weakness, coordination issues, and sensory disturbances. The term can also be used in other contexts, such as systemic sclerosis, which affects the skin and internal organs.
