-Alzheimer disease
Alzheimer disease,degenerative brain disorder that develops in mid-to-late adulthood.it result in a progressive and irreversible decline in memory and a deterioration of various other cognitive abilities.
-Cerebral palsy
A group of neurological disorder characterized by paralysis from abnormal development of or damage to the brain either before birth or during the first year of life
-Stroke
also called apoplexy, sudden impairment of brain function resulting either from a substantial reduction in blood flow to some part of the brain or from intracranial bleeding. The consequences of stroke may include transient or lasting paralysis on one or both sides of the body, difficulties in speaking or eating, and a loss of muscular coordination. A stroke may cause cerebral infarctions—dead sections of brain tissue.
-Polio
in full poliomyelitis, also called infantile paralysis, acute viral infectious disease of the nervous system that usually begins with general symptoms such as fever, headache, nausea, fatigue, and musclepains and spasms and is sometimes followed by a more-serious and permanent paralysis of muscles in one or more limbs, the throat, or the chest.
-Bell Palsy
abrupt paralysis of the muscles on one side of the face due to dysfunction of the seventh cranial nerve, the facial nerve. The disorder is named for the Scottish surgeon Sir Charles Bell, who first described the function of the facial nerve in 1829. The facial nerve supplies the muscles of movement and expression of the face. It also has sensory components that supply taste to the anterior two-thirds of the tongue and sensation in a small area around the ear. In addition, a small nerve extends to a muscle attached to one of the bones of the middle ear, and autonomic fibres extend to salivary and tear glands.
-Hydrocephalos
accumulation of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain, causing progressive enlargement of the head. Normally, CSF continuously circulates through the brain and the spinal cord and is continuously drained into the circulatory system. In hydrocephalus the fluid accumulates in the two large lateral ventricles, and the brain and skull become enlarged because of the accumulation of fluid.

Ailments or Diseases on the Human Nervous System

"Of all the diseases of the nervous system, the most common difficulty that people have is pain, and much of that is nerve-related," according to Dr. Shai Gozani, founder and CEO of NeuroMetrix, a medical device company. "There are 100 million people who live with chronic pain."

Epilepsy, in which abnormal electrical discharges from brain cells cause seizures

Parkinson's disease, which is a progressive nerve disease that affects movement

Multiple sclerosis (MS), in which the protective lining of the nerves is attacked by the body's immune system

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a motor neuron disease which weakens the muscles and progressively hampers physical function

Huntington's disease, which is an inherited condition that cause the nerve cells in the brain to degeneraten

Alzheimer's disease, which covers a wide range of disorders that impacts mental functions, particularly memory.

Stroke, which occurs when there is bleeding on the brain or the blow flow to the brain is obstructed;

Transient ischemic attack (TIA), which are mini-type strokes that last a shorter period of time but mimic stroke symptoms; and

Subarachnoid hemorrhage, which is specifically bleeding in the space between your brain and the surrounding membrane that can be the result of a trauma or rupturing of a weak blood vessel;

Infections such as meningitis, encephalitis, polio, and epidural abscess can also affect the nervous system, the NIH noted.

Treatments vary from anti-inflammatory medications and pain medications such as opiates, to implanted nerve stimulators and wearable devices, Gozani said. "Many people also turn to herbal and holistic methods to reduce pain, such as acupuncture."
