Impulsive behaviors and poor inhibition performances are frequently described in patients with traumatic brain injury (TBI). However, few studies have examined impulsivity and associated inhibition impairments in these patients. Twenty-eight patients with moderate to severe TBI and 27 matched controls performed a stop- signal task designed to assess prepotent response inhibition (the ability...

Introduction: Impulsive behaviors are frequently described in brain-damaged patients, including patients with Alzheimer’s disease (AD). However, few studies have examined impulsivity changes and associated cognitive impairments in AD and healthy controls. Consequently, the first aim of this study was to compare patients with mild AD and matched controls on four dimensions of impulsivity...
