What deficits can arise from cerebellar dysfunction?

Dysfunction in the cerebellum mainly disrupts coordination and the precise timing of movements rather than creating weakness or sensory loss. This shows up as ataxia — unsteady, clumsy movements with impaired gait and balance — and dysmetria — an inability to judge distance or the required range of movement, causing overshooting or undershooting when reaching for a target or performing rapid, alternating actions. You might also see related signs like intention tremor, where tremor worsens as you approach a target, or difficulty with performing smooth, coordinated tasks. Other deficits listed don’t fit cerebellar effects. Amnesia and aphasia involve memory and language areas in the cortex, not the cerebellum. Paralysis and numbness point to loss of motor strength or sensory input, typically from issues in the motor or sensory pathways rather than the cerebellum. Hemiparesis specifically is weakness on one side, usually due to damage to the motor cortex or corticospinal tract.
