Cerebellar atrophy primarily affects the coordination functions of patients, leading to symptoms such as unstable walking and unsteady handling of objects with the hands. This condition does not have a significant connection with human consciousness, and does not affect the reticular structure of the brainstem or the cerebral cortex. Therefore, patients with cerebellar atrophy do not experience confusion or cognitive impairments. If a patient with cerebellar atrophy does exhibit confusion, it is important to consider other possible causes, such as electrolyte disturbances due to poor food intake or concurrent diseases, such as cerebral cortex thrombosis, hemorrhage, or brainstem infarction. It is necessary to conduct additional laboratory tests and cranial magnetic resonance imaging to confirm these conditions.
