The present patient appears to have a drug induced movement disorder that appeared with induction of medication and disappeared after drug cessation. The temporal pattern suggests that the movement is one of the acute-subacute neuroleptic related disorders: akathesia, dystonia, or parkinsonism. The resting tremor, loss of spontaneous facial expression, poor associated movements, and mild cogwheel rigidity indicate the diagnosis as parkinsonism. Two methods hae been described for evaluated the above patient. Clearly the same diagnosis is established whether the clinician approaches the problem descriptively (the diagnosis of tremor) or historically (the diagnosis of neuroleptic related disorder). Familiarity with both methods provides the clinician with the plasticity to integrate observation and pharmacology with an understanding of the pathophysiology of movement disorders.
