Catalepsy is a nervous disorder characterized by immobility and muscular rigidity, along with a decreased sensitivity to pain. Catalepsy is considered a symptom of serious diseases of the nervous system (e.g., , , etc.) rather than a disease by itself. Cataleptic fits can range in duration from several minutes to weeks. Catalepsy often responds to

Epilepsy is an unpredictable, serious, and potentially fatal disorder of the nervous system, thought to be the result of faulty electrical activity in the brain. Epileptic seizures result from abnormal, excessive, or hypersynchronous neuronal activity in the brain. About 50 million people worldwide have epilepsy, and nearly 80% of epilepsy occurs in developing countries. Epilepsy becomes more common as people age. Onset of new cases occurs most frequently in infants and the elderly. Epileptic seizures may occur in recovering patients as a consequence of brain surgery.

ADHD () is now largely considered to be a genuine organic disorder of the nervous system, according to the United States government. ADHD, which in severe cases can be debilitating, has symptoms thought to be caused by structural as well as biochemical imb in particular, low levels of the neurotransmitters
and norepinephrine, which are responsible for controlling and maintaining attention and movement. Many people with ADHD continue to have symptoms well into adulthood. Also of note is an increased risk of the development of , or (DLB), & a direct genetic association of
two progressive, and serious, neurological diseases whose symptoms,often occur in people over age 65.

Parkinson’s disease, or PD, is a progressive illness of the nervous system. Caused by the death of dopamine-producing brain cells that affect motor skills and speech. Symptoms may include
(slow physical movement), muscle rigidity, and tremors. Behavior, thinking, sensation disorders, and the sometimes co-morbid skin condition
are just some of PD's numerous nonmotor symptoms. Interestingly, ,
(ADHD) & , all appear to have some connection to one another, as all three nervous system disorders involve lower than normal levels of the brain chemical (In ADHD, Parkinson's, & the depressive phase of Bi-polar disorder.) or too much dopamine(In,Mania or Manic states of .) in different areas of the brain:
