Ataxia is usually caused by damage to a part of the brain controlling muscle movement, called the “cerebellum”. It can also be caused by damage to other parts of the nervous system, including the spinal cord.
The damage can be the result of another medical condition, such as multiple sclerosis (MS), or can be caused by a stroke, tumor, head injury, long-lasting alcohol abuse, certain medications or other causes. This type of ataxia is called “acquired ataxia”.
Ataxia can also be caused by defective genes that the affected person inherited from their parents. The parents may or may not have been affected by ataxia themselves. This type of ataxia is called “hereditary ataxia”.
Sometimes ataxia can also develop because the brain is progressively damaged over time for unknown reasons. This type of ataxia is called “idiopathic late-onset cerebellar ataxia (ILOCA)”. Symptoms of ILOCA usually develop around 50 years of age and gets progressively worse over time.
