The main functions of the cerebellum include maintaining bodily balance, controlling posture and gait, regulating muscle tone, and coordinating the accuracy of voluntary movements. Therefore, the primary symptoms of cerebellar atrophy involve ataxia, with patients displaying instability in standing, a staggering gait similar to that of a drunken walk; speech may manifest as cerebellar speech, or a chanting-like pattern; there can also be disorders in fine motor skills, where some precise movements cannot be accurately performed, and coarse movements may sometimes not be severely affected; additionally, there can be disturbances in eye movement, presenting as tremors of both eyes, and patients may experience symptoms of vertigo clinically.
