Poster (in Polish) presented at the Congress of Polish Psychatrists (KPP 2001)

The Congress of Polish Psychiatrists was my first exposure to a major scientific conference. Together with the regular staff of the Child Psychiatry Clinic in Warsaw, we presented results of an investigation of prevalence of tic disorders among Warsaw schoolchildren. Complete results of the prevalence estimates for particular disorders were published few years later in the journal European Child and Adolescent Psychiatry.
