In the last 15 years, the dimensions of impulsivity have been refined and extended to include urgency, defined as impulsivity during strong emotional states. Urgency has been shown to be elevated in a number of at-risk populations, including substance use disorders, bipolar disorder, and eating disorders. In people with schizophrenia, lab investigations recently found that urgency is strongly associated with aggressive attitudes in schizophrenia, and indeed urgency accounted for much of the elevated aggression seen  in those patients. What was also evident is that reduced cortical thickness and resting functional synchronization of ventral prefrontal regions of the brain predicts higher levels of urgency. These results suggest that it is urgency that is particularly relevant to our understanding of impulsive aggression in schizophrenia. Next steps include developing behavioral measures of urgency, better characterizing brain activation patterns during these tasks using a multimodal imaging approach, and using neuromodulation techniques to probe urgency-related circuit abnormalities, with the longer term goal of remediating urgency and aggression in schizophrenia.
