What are the different types of nervous system disorders?
The nervous system consists of the central and peripheral nervous system. The central nervous system is responsible for brain and spinal cord activities and the peripheral nervous system regulates neurons. Due to its complexity, the nervous system is susceptible to diseases that include the brain, spinal cord and other tissues found in the body. Nervous system disorders may include Alzheimer's disease, strokes, multiple sclerosis and epilepsy. Alzheimer's disease, progressive and irreversible disease, mostly affects adults over 60 years. The disease is characterized by memory loss; As the disorder progresses, a person suffering from Alzheimer's disease often experiences confusion, disorientation and changes in behavior when more neurons die in the brains. Alzheimer's diseases may become so becoming that a person affected by this disease may be in bed, unable to communicate and rely on others for basic care.
Vascular disorders that include strokes, temporary ischemickThe attack (TIA) and bleeding are another type of disorder of the nervous system that affects the brain. The person suffers from a stroke when blood flow and oxygen are disrupted into the brain. The cause of stroke may be clots in the brain or bleeding in the brain. During a stroke, one can lose thousands of blood cells, which can lead to permanent brain damage or even death. After experiencing a stroke, the individual may have trouble walking and communication.
Some nervous system disorders may also be the result of the body's immune system that attacks itself. One such autoimmune disorder is multiple sclerosis - MS is also degenerative - which is more common in women than in men. The multiple sclerosis causes nerve impulses that carry messages from the brain and spinal cord that have hay, resulting in a reduction or even loss of body control. Symptoms usually include problems with balance and walking, weakness in the limbs, do not useLost and difficulty. Although there is no known drug for multiple sclerosis, treatment can maintain symptoms under control. However, attacks can lead to a point at which a person suffering from a failure requires the trolley to do.
When electrical pulses in the brain become unstable, a seizure may occur. Seizures are one of the general symptoms of nervous system disorders; Others include headaches, blurred or double vision, lack of coordination and muscle rigidity. Permanent convulsions can lead to a disease of the nervous system known as epilepsy, sometimes referred to as seizure disorder. A person with epilepsy may lose consciousness and experience seizures that may take seconds or minutes. While a person with epilepsii live a normal life with medication, may be endangered if the seizure causes injury due to a fall or occurs when driving.
