Youssuf Saleh et al.

Summary: Research on negative symptoms in schizophrenia has provided insights into reward-related processing impairments and dysfunction within specific brain networks. Associations between negative symptoms and reward-processing deficits, cognitive dysfunction, and other factors suggest the importance of objective behavioral and neural measurements in understanding this complex syndrome. Utilizing findings from other brain disorders through transdiagnostic research may shed light on common origins of motivation disorders across diseases and inform future treatment development.
