| Description | Summary: Background: Negative symptoms represent core features of schizophrenia and have an unfavorable impact on the disease outcome. Unfortunately, their aetiopathology has not been elucidated yet and the effectiveness of available treatments is not satisfactory. Aims: This review aims to provide a critical overview of research findings concerning negative symptom aetiopathology, highlighting limitations and future perspectives. Results: Enduring and transient negative symptoms, as well as motivation-related and expression-related domains of negative symptoms, have different risk factors and clinical correlates, and are associated to distinct brain abnormalities. Enduring negative symptoms seem to be related to subtle, pervasive deviations in neurodevelopmental trajectories. Expression deficit, as compared with avolition, shows a stronger association with neurological soft signs, cognitive impairment and diffuse disconnectivity. Avolition/apathy is a multifaceted construct probably related to deficits of reward and action valuation and instrumental learning, subtended by cortico-striatal dysfunctions. Conclusions: Research findings support the heterogeneity of negative symptoms and are likely to pave the way for the discovery of more effective treatments. |
