Paroxysmal kinesigenic dyskinesia (PKD) is characterized by recurrent and brief attacks of involuntary movement in the trunk and limbs triggered by the sudden initiation of voluntary movement. This report describes a 66-year-old female patient with bipolar disorder (BD) and idiopathic basal ganglia calcification (BGC) who had developed recurrent PKD, which resolved completely with remission of depressive state. Clinicians should regard mood disturbance as a rare, but possible causal factor of transient PKD in subjects with BD and BGC.
