Klazomania was the term applied to the motor and vocal tics seen as a sequel to encephalitis lethargica (von Economo’s disease), along with parkinsonism and oculogyric crises. This observation helped to promote the idea that tics were due to neurological disease rather than being psychogenic, for example in Gilles de la Tourette syndrome.
