Patients with cerebellar atrophy usually exhibit the following symptoms: First, these patients generally experience significant dizziness, with some displaying vertigo, a symptom that requires clinical attention. Second, these patients typically exhibit unstable walking as a clinical symptom, and even standing can be very difficult. Third, these patients will experience limb ataxia. For example, when they try to touch their nose with their finger, they miss. Their hands also shake when trying to hold objects. Fourth, individuals with brain atrophy may also exhibit unclear speech, with symptoms such as explosive sounds when speaking. Additionally, the cause of cerebellar atrophy may vary, which can lead to other symptoms. For instance, cerebellar atrophy caused by multisystem atrophy may also present Parkinson-like symptoms.
