Cerebellar atrophy may present with presenting symptoms such as ataxia, dysarthria, and oculomotor deficits. 1. Ataxia: when patients with cerebellar atrophy may appear to be unsteady, shaking, and have difficulty standing on their feet, hobbling gait, walking left and right swaying and other ataxia symptoms. 2. Dysarthria: when patients with cerebellar atrophy, they may have slow speech and nasal sound due to ataxia of the muscles of the mouth, lips, tongue, throat and other organs of articulation. 3. Ophthalmoplegia: when the patient’s cerebellum is atrophied, extraocular muscle movement disorder may appear, causing symptoms such as downbeat nystagmus and rebound nystagmus. In addition, when patients suffer from cerebellar atrophy, cognitive and language dysfunction can occur. When patients have cerebellar atrophy, they should be actively treated under the guidance of a doctor.
