Degenerative Nerve Diseases

Also called: Neurodegenerative diseases

Degenerative nerve diseases affect many of your body's activities, such as balance, movement, talking, breathing, and heart function. Many of these diseases are genetic. Sometimes the cause is a medical condition such as alcoholism, a tumor, or a stroke. Other causes may include toxins, chemicals, and viruses. Sometimes the cause is not known.

Degenerative nerve diseases include

  • Alzheimer's disease
  • Amyotrophic lateral sclerosis
  • Friedreich's ataxia
  • Huntington's disease
  • Lewy body disease
  • Parkinson's disease
  • Spinal muscular atrophy

Degenerative nerve diseases can be serious or life-threatening. It depends on the type. Most of them have no cure. Treatments may help improve symptoms, relieve pain, and increase mobility.
