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
