Overview
Other diagnostic studies
Response to dopaminergic therapy: One of the useful methods in diagnosing PD is patient response to dopaminergic therapy. Levodopa and apomorphine challenge tests in proven to be useful in distinguishing PD from other parkinsonian syndromes.[1]
Autonomic testing: Autonomic testing including cardiac sympathetic denervation, urodynamic testing, anal or urethral EMG, sympathetic skin responses, quantitative sudomotor axon reflex test, tilt table test and heart rate variability during forced respirations are also useful in diagnosing PD.[1][2]
Olfactory testing: Olfactory testing is a useful test since olfactory dysfunction in common in PD but not in other parkinsonian syndromes and essential tremor.
