Ataxia vs. Apraxia: Know the Difference
By Shumaila Saeed || Published on February 9, 2024
Ataxia refers to a lack of muscle coordination during voluntary movements, while Apraxia is the inability to perform movements or gestures despite having the desire and physical capability.
Key Differences
Ataxia is a neurological sign and symptom, involving a lack of coordination in muscle movements. Apraxia is a motor disorder caused by damage to the brain, where individuals have difficulty with the motor planning to perform tasks or movements.

Ataxia can be caused by damage to different parts of the nervous system, such as the cerebellum, and can be due to genetic factors, infections, injuries, or degenerative diseases. Apraxia often results from neurological disorders such as stroke, brain injury, or dementia, affecting the brain's ability to translate thoughts into actions.

Ataxia manifests as poor coordination, unsteady walk, difficulty with fine motor tasks, and speech problems. Apraxia involves difficulty in executing voluntary movements, despite having the desire and physical ability to perform them.

Ataxia is diagnosed through physical examinations, medical history, and may involve genetic testing, MRIs, or CT scans. Apraxia is diagnosed based on symptoms, medical history, and neurological assessments; brain imaging tests may also be used.

Ataxia treatment focuses on the underlying cause if known, with physical therapy, occupational therapy, and speech therapy as supportive treatments. Apraxia management includes speech therapy, occupational therapy, and sometimes medications, depending on the underlying cause.
