Ataxia refers to

• A. Lack of Muscle Coordination
• B. Memory Loss
• C. Blurred Vision
• D. Seizures

Answer: (A)

Ataxia is a sign of impaired coordination of voluntary movements. It manifests as unsteady gait, clumsy fine motor skills, and difficulty with tasks that require precise timing, often due to dysfunction in the cerebellum or its neural pathways. This is why "lack of muscle coordination" is the best match. The other options describe memory problems, visual disturbances, or seizure activity—each involves different brain processes and presents differently than ataxia.
