Ataxia is a neurological condition characterized by lack of coordination, balance and control of movements. It can affect people in various ways, causing them to have difficulty with tasks that require fine motor skills or equilibrium. Ataxia may be caused by damage to the part of the brain responsible for controlling movement (cerebellum) or as a result of other neurological conditions such as multiple sclerosis or cerebral palsy. The severity and symptoms can vary greatly depending on the individual case, but common signs include difficulty walking, speech problems, tremors, and poor coordination.
