This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Psychiatry
All of the following are findings of patients with schizophrenia except 
Select and explain. 
A. Lateral and third ventricle enlargement, B. Deficits in smooth-pursuit eye movements, C. Increased incidence of abnormally slow electroencephalogram tracings, D. Cerebellar dysfunction
D: Cerebellar dysfunction
Answer: D: Cerebellar dysfunction 
Explanation: Studies using CT have consistently shown that the brains of patients with schizophrenia have lateral and third ventricular enlargement and some degree of reduction in coical volume. Disorders of smooth visual pursuit and the disinhibition of saccadic eye movements are commonly seen in patients with schizophrenia. Electroencephalographic studies of patients with schizophrenia indicate that a high number have abnormal records, increased sensitivity to activation procedures, decreased a-activity, and increased 7- and 8-activity. No studies have shown impaired cerebellar functioning.
