Forensic assessment Are biological facts useful?

Prognoses in forensic psychiatry are demanded and delivered on a daily basis. Given the multitude of different causes, it is not surprising that prognostic questions also widely differ. To predict the likelihood of criminal re-offences, risk checklists are used; biological parameters are rarely considered. This text outlines exemplary (neuro-)biological investigations and methods and their relevance to the diagnosis and treatment of psychiatric disturbances. Their possible relevance with regard to forensic psychiatric prognoses is also discussed. It is suggested that biological facts must be investigated as additional predictors.
