[Cyberstalking].

The term cyberstalking appears in the media with increasing frequency. So far epidemiological studies are sparse. Since researchers have used different definitions and study samples for cyberstalking, widely varying prevalence rates have been published. We report here a case of cyberstalking and discuss available empirical data. Cyberstalking may cause psychological distress similar to that of real world stalking. The need for a scientific definition of cyberstalking and for future studies is presented. Since it is likely that psychiatrists will encounter victims of cyberstalking they should have knowledge of this phenomenon.
