          Amotivation and Anhedonia Key to Social Functioning in Schizophrenia

          Amotivation and anhedonia, rather than expressive dysfunction, are crucial to determining the social functioning of individuals with schizophrenia. The transdiagnostic network analysis examined the relationship between negative symptoms, other psychopathologies, and social functioning in patients with schizophrenia, major depressive disorder, and bipolar disorder.

          A Drug That Increases Dopamine Can Reverse the Effects of Inflammation on the Brain in Depression

          Levodopa, a drug commonly prescribed for the treatment of Parkinson's disease that increases dopamine in the brain was found to reverse the effects of neuroinflammation on the reward system and improve symptoms associated with depression.

          When Chronic Stress Activates These Neurons, Behavioral Problems Like Loss of Pleasure and Depression Result

          Anhedonia and depression arise when POMC neurons in the arcuate nucleus of the hypothalamus become hyperactive as a result of chronic stress. Reducing the activity also reduces feelings of depression and loss of pleasure.

          Brain Circuitry Identified That May Be Responsible for Negative Emotional Aspects of Pain

          A new rodent study uncovers a neural circuit in the brain that appears to govern pain-induced anhedonia. Altering the activity of this circuit restored motivation in pre-clinical models of pain.

          Functional Brain Network Predicts Real-Life Social Network in Both Individuals With Schizophrenia and Social Anhedonia

          Patients with schizophrenia, but not those with social anhedonia, exhibited deficits in real-life social network size. Those with schizophrenia and those with social anhedonia had reversals functional connectivity to one another. People with schizophrenia showed decreased segregation and functional connectivity in brain areas associated with social behaviors, while those with social anhedonia had an increase in connectivity and segregation.
