Diseases That Affect The Nervous System

Nervous system creates an intricate network of electric signals that are responsible for co-ordinating muscles and their movements. Nervous system is made up of numbers of specialised cells which are called as neurons that convey the signals in between various body parts that in turn controls the actions and reaction of a human body. Any defect in brain or nervous system can hamper the functioning of a body. Most of the disorders that affect nervous system have a genetic component to it and most of them are caused by specific genes. There are numerous diseases that affect the functionality of nervous system and some of the most common diseases are:

Alzheimer’s disease: The disease affects the nervous system and some of the most common symptoms of this disorder are troubles with memory, weak thinking and judgmental capacity. With the advancement of disease patients can experience memory loss and dementia. There is no permanent cure available for this disease though symptoms can be treated with medication.

Epilepsy: It is a disorder that is characterised by recurrent seizures. There are many types of epilepsy and seizures experienced by the patients and the epilepsy drugs try to control the symptoms of seizures as well.

Multiple Sclerosis: It affects brain and nervous system cell and the early symptoms of the disease include tightening, weakness, numbness and blurred vision. Thinking problems, muscle stiffness and urinary troubles are also some of the common symptom of this disease.

Parkinson disease: The nerve cells in the brain that produces dopamine are affected by Parkinson disease. Muscle rigidity, tremors, gait and change in speech are some of the common symptoms of this disease.

Stroke: bleeding in the brain or blocked blood vessels could cause this stroke. This disease creates sudden headache, numbness, weakness, trouble in talking and walking, confusion, dizziness and slurred speech.

Restless Leg Syndrome: This disease creates a strong sensation or urge to move during the night. This unbearable sensation makes it very difficult to sleep in the night.

Amyotrophic lateral sclerosis (ALS): It is a neurological disorder in which progressive degeneration of motor neuron cells occur in brain or spinal cord. If the disease is not treated in time then it can lead to paralysis or death.

Gaucher disease: It is a genetic disorder that affects the nervous system of the body. In this disease the body is not able to break the enzyme properly and thus it leads to a fat deposition in bone marrow, liver and spleen. Enzyme replacement therapy is the most common treatment for this disease.

Lesch-Nyhan syndrome (LNS): This disease disrupts the metabolism of raw materials called as purines that are responsible for gene formation.

Huntington disease (HD): It is an inherited disorder that leads to a degenerative neurological disease. This disease is caused by the mutation in a gene that is found on chromosome 4. More than 30,000 Americans are affected by this disease and many more can get it as an inherited disorder from their parents.
