Pathol a hardening or thickening of organs, tissues, or vessels from chronic inflammation, abnormal growth of fibrous tissue, or degeneration of the myelin sheath of nerve fibres, or (esp on the inner walls of arteries) deposition of fatty plaques 2. the hardening of a plant cell wall or tissue by the deposition of lignin Sclerosis the hardening of an organ or tissue in humans and animals caused by connective-tissue overgrowth. Functionally valuable elements of the parenchyma of a sclerosed organ are destroyed and replaced by mature and sometimes coarse-fibered connective tissue, which often contains deposits of amyloid, hyalin, and lime. New connective tissue is usually formed by the reproduction of fibroblasts (connective-tissue cells) and by the intensified formation of collagen molecules by the fibroblasts. In cases of sclerosis, parenchymal elements may be destroyed by inflammatory processes that are usually chronic in nature, including tuberculosis, rheumatic fever, and syphilis, and by circulatory disturbances, including passive congestion. Parenchymal elements may also be destroyed by involutional changes, for example, the postpartum sclerosis of the corpus lutea, and by changes associated with age and by metabolic disturbances. Sclerosis may be focal or diffuse. The proliferated connective tissue may become corrugated, resulting in the deformation of the organ, or cirrhosis. During cirrhosis, the hardening and reduction of an organ are accompanied by surface changes, including alternating outpouchings and invaginations, such as in a granular kidney or nodular liver. sclerosis[sklə′rō·səs] (pathology) Hardening of a tissue, especially by proliferation of fibrous connective tissue. sclerosis
sclerosis [sklĕ-ro´sis] an induration or hardening, especially of a part from inflammation, or in disease of the interstitial substance.

- (in plants), a hardening of the cell wall or tissue, often due to the deposition of LIGNIN.

I 've become very irritable towards my family. Seems like I've become a mean person, and that has not my charactor.A. MS can indeed cause depression or other mood changes such as euphoria, so it may be part of the disease. In addition, some treatments may also cause mood changes. If it bothers you, than consulting your doctor may be wise.
Take care…
Q. What is MS? I am 14 years old and my best friend has been diagnosed with MS. What is it? What causes it? Can I catch it?A. Multiple sclerosis (MS) is an autoimmune disease in which the body's immune system attacks the central nervous system (CNS), causing demyelination (loss of myelin). The myelin sheath helps the neurons (nerves) carry electrical signals. When having MS there is a thinning or complete loss of myelin and, sometimes, the cutting of the neuron's extensions or axons. When the myelin is lost, the neurons can no longer effectively conduct their electrical signals. It may cause numerous physical and mental symptoms. MS is not contagious and does not shorten the life expectancy of those who are diagnosed with the disease. Although the disease may not be cured or prevented at this time, treatments are available to reduce severity and delay progression.
