The nervous system is composed of the central nervous system and the peripheral nervous system. Together both systems are responsible for controlling the five senses, voluntary as well as involuntary functions, the thought process and the ability to reason out. The symptoms when there is a problem with the central nervous system are dependent on the area where the problem occurs. The problem could be gradual or it can come all of a sudden. And, the symptoms can be severe, or they can be mild.
Some of the problems of the central nervous system that cause serious symptoms include injury to the brain or spinal cord, infections of the brain or the membrane enveloping the brain and spinal cord, degenerative conditions, taking illicit drugs, prescription medications or alcohol, getting exposed to toxic chemicals, and imbalance of neurotransmitters.
Strokes are one of the most common problems associated with the central nervous system. This condition comes on suddenly and can be life-threatening if not treated promptly. Symptoms include numbness of one side or both sides of the body, vision impairment, loss of speech, sudden onset of severe headache, feeling dizzy, unable to walk or stand steadily, confusion, nausea and vomiting.
Seizures are another type of problem associated with the central nervous system. They can cause twitching of the muscles and abnormal movement of the body. The severity of a seizure is dependent on the cause as well as the region of the brain that is involved.
Headaches are caused due to a problem in the central nervous system. However, invariably this problem is not severe. The headache can be a throbbing pain or it can be a severe stabbing pain. Headaches invariably occur due to a problem associated with the scalp, muscles that surround the head and sinuses.
Many people complain of dizziness and vertigo. Usually, this can occur due to a problem in the brain, but it can also occur due to a problem associated with the inner ear or taking certain type of medication. Some people can suffer from dizziness due to blood pressure or even dehydration.
When there is an imbalance of neurotransmitters, the person may show changes in behavioral patterns, mood swings, problems sleeping, sexual dysfunction or mental ailment. However, the symptoms are dependent on which neurotransmitter is deficient or lacking.
Hence, there are many problems associated with the central nervous system and each one has its own set of symptoms. If a person is experiencing any of the symptoms that are common associated with central nervous system problem, it needs immediate medical attention, or it can cause life long damage to the person's body, health and the system itself.
