Neurological Diseases
Neurological diseases are disorders that attack the nervous system, causing various symptoms. Depending on the type of disease and its cause, every neurological condition exerts some form of influence on the nervous system. This manifests as functional impairment, such as loss of strength, speech disturbances, impaired coordination, and more.
Autoimmune Neurological Diseases
The human body is built to prevent the penetration of pathogens or to destroy them if they have already entered, using two systems: the innate immune system, which has a non-specific response, and the acquired immune system, which provides specific protection against pathogens.
The immune system operates based on the distinction between 'self' and 'non-self', and is not supposed to act against that which is 'self'. Occasionally, the immune system fails to make this distinction and creates auto-antibodies and cytotoxic T-cells, which attack and destroy the body's own tissues and organs. This attack by the immune system against the 'self' is known as an autoimmune response.
While the immune system is meant to protect the body from the invasion of viruses, bacteria, and external pathogens, in an autoimmune disease, the body actually attacks cells and tissues belonging to the body itself. This self-attack is accompanied by an immune overreaction, such as the creation of auto-antibodies and the development of inflammation in various parts of the body. As a result, an autoimmune disease can cause damage to various systems and organs, such as cirrhosis of the liver, for example.
