Nervous system diseases include degenerative diseases, such as multiple sclerosis, Parkinson’s disease and Alzheimer’s disease; brain tumors; and infections, such as encephalitis or meningitis, according to WebMD. Nervous system functioning may also be impaired due to shock and trauma to other organs, such as heart or liver failure.
Symptoms of a nervous system disease, or a condition that affects the nervous system, may be degenerative or acute, explains WebMD. Degenerative symptoms appear gradually and lead to slow loss of function over time, while acute symptoms appear suddenly and may cause significant loss of function immediately. The symptoms that appear in any given case depend on the part of the nervous system affected and the cause.
Individuals experiencing acute symptoms of a nervous system condition may experience problems with balance, coordination and mental functioning, states WebMD. Typical symptoms include strong nausea, dizziness, a strong headache, impaired speech, loss of vision, numbness and partial or total paralysis. Some of the most common acute nervous system problems include transient ischemic attack and stroke.
Methods for preventing nervous system diseases include staying mentally active, regularly exercising, staying hydrated and eating a diet rich in fruits and vegetables, notes WebMD. Ways to maintain mental sharpness include continually learning new skills and concentrating only on one subject at a time. Limiting caffeine intake helps with hydration, in addition to drinking plenty of water. A diet rich in fruits and vegetables should include plenty of vitamins B6 and B12.
