How stress disrupts emotion control in people with mental health conditions

New research suggests that acute stress may impair key brain functions involved in managing emotions — particularly in people living with ‘distress disorders’ such as depression, anxiety, and borderline personality disorder.

Could AI understand emotions better than we do?

Potential new treatment for Alzheimer’s disease, other neurodegenerative conditions

Worldwide, more than 55 million people suffer from dementia caused by Alzheimer’s Disease (AD) and other conditions that destroy cells in the brain and nervous system. While there is no treatment to control or manage these neurodegenerative conditions,…

Biological markers for teen depression

Using a novel lab method they developed, researchers have identified nine molecules in the blood that were elevated in teens diagnosed with depression. These molecules also predicted how symptoms might progress over time. The findings of the clinical s…

Antidepressant withdrawal symptoms more common among long-term users

People who have been taking antidepressants for more than two years are substantially more likely to experience withdrawal symptoms compared to short-term users when they come off the medication, finds a new study.

Are groovy brains more efficient?

The smallest grooves on the brain’s surface, unique to humans, have largely been ignored by anatomists, but recent studies show that they’re related to cognitive performance, including face recognition and reasoning ability. A new study shows that the …

Promising new way to modulate brain cell activity to potentially treat major depressive disorder in adults

A mechanism involving potassium channels in the brain that control brain cell activity could provide a new and fundamentally different way of treating depression symptoms in adults with major depressive disorder.

Emotional expressions shape how help is received in the workplace

The way people express emotions while helping others can influence whether their assistance is welcomed, resented, or reciprocated, according to new research.

Common antidepressants could help the immune system fight cancer

SSRIs boosted the ability of T cells to kill cancer cells and suppressed tumor growth in both mouse and human tumor models.
