Ataxic cerebral palsy is primarily associated with damage to which brain region?

• A. Cerebellum
• B. Cerebral cortex
• C. Brainstem
• D. Thalamus

Answer: (A)

Coordinated movement relies on the cerebellum to fine-tune balance, posture, and the timing of motor commands. When the cerebellum is damaged, movements become unsteady and clumsy, with a wide-based gait, intention tremor, dysmetria, and difficulty with rapid, alternating movements—classic signs of ataxia. In ataxic cerebral palsy, this cerebellar injury underlies the symptoms, making the cerebellum the primary region involved. Damage to the cerebral cortex tends to produce spasticity and UMN signs, while brainstem or thalamic injuries cause other motor-sensory issues rather than the hallmark ataxic coordination problems.
