Neurological soft signs (NSS) contribute to the prediction of dangerousness in mentally disordered offenders?

The prediction of dangerousness in mentally disordered offenders is still as well complex as insufficiently empirically proven. So far more or less valid criteria for predicting recidivism have been determined concerning historical and clinical aspects. Whereas biological, neurological and neuropsychological variables that could be of importance for the development of chronic delinquent behavior have mostly been neglected. This article deals with the relevance of neurological soft signs (NSS) for the prediction of dangerousness in mentally ill offenders as one possible factor in a multidimensional model. 155 patients were examined after a minimum time at risk of 2 years (mean 4 years). The results showed that on the one hand there is no relevant and valid connection between neurological soft signs and recidivism for the general heterogeneous group of forensic patients. On the other hand similar results arose for the subgroup of patients with a personality disorder without intellectual deficits as for the homogeneous group of offenders in prisons [7,8]. Therefore a significant meaning of NSS for certain subgroups can be presumed.
