Select and explain. 
A. Parkinsonism, B. Nigrostriatal degeneration, C. Wilson's disease, D. Hallervorden-Spatz disease
C: Wilson's disease
Answer: C: Wilson's disease 
Explanation: Answer- C. Wilson's diseaseWilson disease:Wilson disease usually presents with tremors, rigidity, dementia, and pseudobulbar features and has an autosomal recessive mode of inheritance.Slit-lamp examination of the eyes may reveal a Kayser-Fleischer ring.MRI in Wilson disease exhibits the characteristic changes consisting of high-intensity lesions in the basal ganglia, thalami, and mid brain on T2-weighted images. The normal low intensity of red nuclei and SN surrounded by abnormal high-signal intensity in the tegmentum of the mid brain gives rise to the typical 'face-of-the-giant-panda' sign.Best diagnostic clue is symmetrical T2 hyperintensity.
