The central nervous system consists of the brain and spinal cord. Diseases of the central nervous system are a large spectrum of symptomatology and are characterized by damage to the nerve fibers of the brain or spinal cord.
Parkinson's disease is the most common disease of the central nervous system. According to statistics, every hundredth person, aged more than 60 years, is exposed to him .The most famous victims of Parkinson's syndrome are boxer Mohammed Ali, Pope John Paul II and politician Yasser Arafat. Parkinson's disease is caused by a violation of dopamine production.
Dopamine is a substance that promotes impulse transmission in the brain. Violation of its development leads to a progressive change in the cells of the brain, which are responsible for human movements. Recently, a genetic predisposition to this disease has been proven. The causes of the disease can also serve as encephalitis, excessive intake of drugs, synthetic forms of heroin, as well as atherosclerosis of cerebral vessels.
Mandatory symptoms of Parkinson's syndrome are associated with the musculoskeletal system: stiffness of movements;trembling, which occurs in a state of rest, imbalance, trouble with walking. Diagnosis of the disease at an early stage contributes to a significant weakening of symptoms. Complete recovery is not possible .
Stroke is called brain damage, accompanied by acute development of .This type of disease ranks second in the world among causes of premature death. The consequences of stroke are catastrophic - about 85% of patients die or remain disabled for life. But even in surviving patients more than 50% in the next few years of life there is a second stroke.
The onset of a stroke is associated with constriction, blockage or rupture of blood vessels that deliver blood to the brain. With ischemic stroke, the artery that carries blood to the brain is compressed or clogged. That is, the brain does not receive oxygen, and the cells begin to die. With hemorrhagic stroke there is a sharp rupture of the wall, the so-called defective artery, and blood is poured throughout the brain tissue. Patients die from high blood pressure on the cerebral cortex.
To diseases of the central nervous system, is also attributed to a migraine, which can be caused by disorders of the cerebral vessels .
