  • Amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease)
  • Brain injury
  • Brain tumor
  • Cerebral palsy
  • Guillain-Barre syndrome
  • Head injury
  • Huntington's disease
  • Lyme disease
  • Multiple sclerosis
  • Muscular dystrophy
  • Myasthenia gravis
  • Parkinson's disease
  • Stroke
  • Wilson's disease

Some medications, such as narcotics or sedatives, also may cause dysarthria.
