Ataxia: Symptoms & Signs

Ataxia refers to problems with coordination and unsteadiness due to the brain's inability to regulate posture and regulate the strength and direction of limb movements.

Signs and symptoms of ataxia include

  • poor coordination,
  • unsteady walk or gait,
  • stumbling,
  • difficulty with fine motor tasks,
  • changes in speech,
  • nystagmus (involuntary eye movements from side to side),
  • difficulty swallowing, or
  • tremors.

Cause of ataxia

Ataxia is a symptom rather than a disease in itself and has numerous causes. Disease in the cerebellum of the brain, which lies beneath the back part of the cerebrum, usually causes ataxia. Causes can include alcohol or drug abuse, brain tumors, head trauma, infections, stroke, cerebral palsy, and multiple sclerosis. There are also certain inherited genetic conditions that can cause ataxia.
