Which symptom indicates cerebellar damage in a patient with traumatic brain injury?

• A. Ataxia
• B. Aphasia
• C. Photophobia
• D. Diaphoresis

Answer: (A)

Cerebellar damage disrupts coordination, balance, and the smooth timing of movements. The symptom that best indicates this involvement is ataxia, which shows up as an unsteady, clumsy, and poorly coordinated gait and difficulties with precise voluntary movements. In traumatic brain injury, you’d expect signs like wide-based gait, limb incoordination, and problems with rapid alternating movements when the cerebellum is affected. Aphasia is a language impairment usually arising from cortical (language-dominant hemisphere) damage, not the cerebellum. Photophobia is light sensitivity often linked to migraines or eye/cranial issues, not cerebellar injury. Diaphoresis is sweating from autonomic arousal and is not specific to cerebellar damage.
