Research links common sweetener with anxiety in mouse study

Florida State University College of Medicine researchers have linked aspartame, an artificial sweetener found in nearly 5,000 diet foods and drinks, to anxiety-like behavior in mice. Along with producing anxiety in the mice who consumed aspartame, the effects extended up... Continue Reading →

A ‘factory reset’ for the brain cures anxiety, drinking behavior

Gene editing may be a potential treatment for anxiety and alcohol use disorder in adults who were exposed to binge drinking in their adolescence, according to the results of an animal study published in the journal Science Advances. The study... Continue Reading →

Anxiety and Neuroticism Linked to Ability to Experience ASMR

New research from Northumbria University suggests a link between personality traits and the ability to experience the relaxing sensory phenomenon known as ASMR. The findings also show that it reduces anxiety in those who experience the sensation. A study has... Continue Reading →

Researchers achieve remote control of hormone release

Abnormal levels of stress hormones such as adrenaline and cortisol are linked to a variety of mental health disorders, including depression and posttraumatic stress disorder (PTSD). MIT researchers have now devised a way to remotely control the release of these... Continue Reading →

Breakthrough brain research could yield new treatments for depression

Engineers and physicians at USC and the University of California, San Francisco have discovered how mood variations can be translated, or decoded, from neural signals in a person’s brain — a process that has not been demonstrated before. The study,... Continue Reading →

Fright and flight: deciding when to escape

How does your brain decide what to do in a threatening situation? A paper published in Nature describes a mechanism by which the brain classifies the level of a threat and decides when to escape. Escaping from a dangerous situation is crucial... Continue Reading →

Scientists Suggest That Specific Brain Circuits Could Unlock New Psychiatric Treatments

A McLean Hospital scientific team’s comprehensive analysis of recent research into how the brain shapes responses to cognitive and emotional challenges has revealed the potential for new brain treatments for psychiatric conditions that target specific brain circuits. The detailed review,... Continue Reading →

Scientists show how brain circuit generates anxiety

Neuroscientists at Cold Spring Harbor Laboratory (CSHL) have identified a neural circuit in the amygdala, the brain’s seat of emotion processing, that gives rise to anxiety. Their insight has revealed the critical role of a molecule called dynorphin, which could serve as... Continue Reading →

Depression speeds up brain ageing, find psychologists

Psychologists at the University of Sussex have found a link between depression and an acceleration of the rate at which the brain ages. Although scientists have previously reported that people with depression or anxiety have an increased risk of dementia... Continue Reading →
