Question

Quizplus · Accepted Answer

The symptoms described indicate a dysfunction in the cerebellum. The cerebellum is responsible for maintaining balance, coordinating voluntary movement, and regulating muscle tone. A dysfunction in the basal ganglia would present with more rigid movements and a difficulty initiating movement. A dysfunction in the midbrain or brainstem would present with more severe symptoms, such as difficulty breathing, heart rate changes, or loss of consciousness. Dysfunction in the cerebral cortex would present with symptoms more specific to the affected area, such as speech difficulties if in the language area or motor difficulties if in the motor cortex.
