The evolution of laws and regulations are addressed, as is the bifurcation of treatment between forensic hospitals and correctional settings. Prevalence data of personality disorders in the Dutch systems are presented, and comparisons between the Dutch and American systems are delineated. Current treatment modalities are described.
