Theme (Parkinson’s disease)

A 60-year-old female presented with tremors in hands for 6 months. Tremors were more marked on the right side. Tremors were prominent in the resting condition. She has become slow to work. She climbs the stairs better than to walk on the floor. She has expressionless face. She has no muscle weakness.

Her pulse and blood pressure are normal.

She has normal complete blood count, random blood sugar, urea, creatinine and electrolytes.
