Re-emergent Tongue Tremor in Neuroleptic Induced Parkinsonism

Shweta Prasad, Vikram V. Holla, Pramod K. Pal


Background: A re-emergent tremor is suggested to be specific to Parkinson’s disease and although a tongue tremor has been reported in levosulpiride-induced parkinsonism (LIP), re-emergence has never been reported.

Case Report: A 59-year-old female presented with a 3-month history of bradykinesia, 2-week history of right-leg tremor, and 10-day history of lip and tongue tremor. A review of the medication revealed a 15-month history of levosulpiride consumption. On examination, asymmetric bradykinesia, rigidity, rest tremor of the right leg, and re-emergent tongue tremor were observed. The parkinsonism subsided after levosulpiride was stopped.

Discussion: This is the first report of re-emergent tongue tremor in LIP.
