Disease Of Nervous System

Disease Of Nervous System
The nervous system and the brain form an intricate system of electrical signals responsible for muscle, speech, thought, emotion, and senses coordination. A neurological disease, or a disease of the nervous system, is one that affects the nervous system of the body. Several neurological diseases that have a direct effect on the nervous system have a characteristic genetic component - some may be as a result of mutation in a singular cell, while others can have a more intricate mode of inheritance.

Being such an important part of the human body, each disease of the nervous system isn't a rare condition, even though some are definitely direr compared to others. Important to keep in mind is that these diseases will either affect the peripheral nervous system or the central nervous system. The central nervous system is the most important part of the nervous system which includes the spinal cord and the brain. The peripheral nervous system on the other hand extends from the central nervous system to the limbs and torso.

Examples of the first category of diseases of the nervous system caused by faulty genes are muscular dystrophy and Huntington's disease, which of course will be passed down from one generation to another. A disease of the nervous system can also be as a result of an irregular development of the nervous system such as the Spina bifida condition caused by the abnormal formation of the spinal cord. Note that these kinds of diseases have no cure.

An injury to the brain or the spinal cord can also cause a disease of the nervous system. Paraplegic patients will normally have suffered a severe injury of either of the two parts. Basically, where the injury occurs, the patient will be paralyzed from that point down. An immediate treatment of such injuries can reduce long-term effects of the diseases. Alzheimer's and Parkinson's diseases are examples of diseases of the nervous system under the category of degenerative neurological diseases. In other words, the nerve cells progressively get damaged and die eventually.

Falling in the degenerative neurological diseases are seizure disorders such as epilepsy, which is caused by a group of nerve cells sending out the wrong signals. Infections or cancer can also cause neurological diseases. While the cause of brain cancer is yet to be determined, it can be treated using chemotherapy and surgery. Meningitis, caused by viruses getting in the body through open cavities and traveling to the brain may also cause a disease of the nervous system.
