Study uncovers neuronal circuitry that may play a key role in mediating pain-induced anhedonia

A new study published today in Nature Neuroscience has uncovered neuronal circuitry in the brain of rodents that may play an important role in mediating pain-induced anhedonia - a decrease in motivation to perform reward-driven behaviors.

Methylglyoxal detoxification deficits can be involved in the development of schizophrenia

Methylglyoxal (MG) is a highly reactive α-ketoaldehyde formed endogenously as a byproduct of the glycolytic pathway. MG accumulates under conditions of hyperglycemia, impaired glucose metabolism, or oxidative stress.

Lactate has antidepressant effect in mice, shows study

Depression is the leading cause of disability worldwide. Neuroscientists from Synapsy - the Swiss National Centre of Competence in Research into Mental Illness - based at Lausanne University Hospital (CHUV) and Lausanne University (UNIL) have recently demonstrated that lactate, a molecule produced by the body during exercise, has an antidepressant effect in mice.

Study demonstrates profound anhedonia in people with frontotemporal dementia

People with early-onset dementia are often mistaken for having depression and now Australian research has discovered the cause: a profound loss of ability to experience pleasure - for example a delicious meal or beautiful sunset - related to degeneration of 'hedonic hotspots' in the brain where pleasure mechanisms are concentrated.

First-of-its-kind trial identifies a viable target for treating anhedonia

A first-of-its-kind trial has demonstrated that a receptor involved in the brain's reward system may be a viable target for treating anhedonia (or lack of pleasure), a key symptom of several mood and anxiety disorders.

Brain function changes could help diagnose and manage depression

Ever heard of the lateral habenula? Very few, outside of neuroscience, probably have. Yet a new study, published in the journal Neuron, shows that characteristic changes in the way this area of the brain fires can result in a total loss of will to do anything – which is characteristic of one form of depression.
