Electrophysiological correlates of behavioural inhibition and decision making processes in patients with impulse control deficits

Introduction: Patients with impulse control deficits often show cognitive abnormalities especially in executive abilities e.g. working memory, planning capacity and behavioural inhibition. One possibility to examine the neurophysiological underlying mechanisms of these cognitive deficits is to assess evoked potentials. In the present study an adapted go/nogo-paradigm was used to investigate electrophysiological correlates of voluntary selection and behaviour control processes in patients suffering from alcohol dependence. Methods: 14 patients with alcohol dependence (age=45.86±9.14) and 14 control persons (age=4…
