Clinical Information
  • A non-neoplastic or neoplastic disorder that affects the brain, spinal cord, or peripheral nerves
  • Any deviation from the normal structure or function of the nervous system that is manifested by a characteristic set of symptoms and signs
  • Any deviation from the normal structure or function of the nervous system that is manifested by a characteristic set of symptoms and signs. (nci)
  • Condition in which there is a deviation from or interruption of the normal structure or function of any component of the brain (including the cerebral hemispheres, diencephalon, brain stem, and cerebellum) or the spinal cord
  • Diseases of the central and peripheral nervous system. This includes disorders of the brain, spinal cord, cranial nerves, peripheral nerves, nerve roots, autonomic nervous system, neuromuscular junction, and muscle
  • Impairment of health or a condition of abnormal functioning of the nervous system
  • Neurologic diseases are disorders of the brain, spinal cord and nerves throughout your body. Together they control all the workings of the body. When something goes wrong with a part of your nervous system, you can have trouble moving, speaking, swallowing, breathing or learning. You can also have problems with your memory, senses or mood. There are more than 600 neurologic diseases. Major types include
    • diseases caused by faulty genes, such as huntington's disease and muscular dystrophy
    • problems with the way the nervous system develops, such as spina bifida
    • degenerative diseases, where nerve cells are damaged or die, such as parkinson's disease and alzheimer's disease
    • diseases of the blood vessels that supply the brain, such as stroke
    • injuries to the spinal cord and brain
    • seizure disorders, such as epilepsy
    • cancer, such as brain tumors
    • infections, such as meningitis
Applies To
  • Disorder of nervous system (central) NOS
