Often labeled the brain’s fear center, the amygdala is much more complex than that. A study in Translational Psychiatry suggests that PTSD is linked to altered connectivity in one of its subregions, with potential implications for emotion and body awareness.

East Asia’s wealth and democracy do not translate into higher happiness scores, unlike in the West. A new study suggests five cultural habits may explain this persistent “East Asian happiness puzzle.”

A study in Advanced Science has pinpointed how a high-salt diet can lead to cognitive decline. Researchers found excess salt disrupts a specific molecular pathway in the brain, causing the loss of a protein essential for healthy neuron connections.

A new study provides evidence that misophonia is linked to difficulties in adapting to emotional demands and switching thoughts. The findings point to cognitive and emotional rigidity that may underlie sound sensitivity symptoms.

New research demonstrates that long COVID can be a severely disabling condition. A recent study found individuals with lasting symptoms report worse daily function than 98% of the general population, with a significant negative impact on their overall quality of...

New research provides genetic evidence that neurodevelopmental conditions like ADHD and autism may directly increase the risk for specific heart diseases. The study, published in Cells, used genetic data to uncover potential causal relationships between the disorders.

New research has found that about 31% of women with a clinical ADHD diagnosis also had PMDD. This is a stark contrast to the 9% prevalence in women without ADHD, highlighting a significant at-risk group.

Scientists have identified a chemical produced by a common gut bacterium that travels to the brain and kills dopamine-producing neurons. Published in Nature Communications, the study establishes a direct link between a gut microbe and the development of Parkinson's-like symptoms.

A new study suggests that semaglutide, a drug best known as Ozempic, may reduce cocaine use, motivation, and relapse in rats. These findings point to a possible role for GLP-1-based drugs in treating cocaine addiction.

Could poor sleep be accelerating your brain's aging process? New research suggests it might. A study in Neurology found that chronic insomnia is associated with a more rapid decline in cognitive skills, equivalent to an extra 3.5 years of aging.

New research suggests that higher iron levels in specific brain regions may help identify who is at risk for developing memory problems years before symptoms emerge. The findings may offer a new way to track Alzheimer’s risk using MRI scans.

A small study found a 10-week ketogenic diet was associated with a roughly 70% decrease in depression symptoms, improved well-being, and enhanced cognitive performance in college students already receiving treatment.

New research suggests the Mediterranean diet may be especially powerful for those at high genetic risk for dementia. The study found this diet more effectively modulates dementia-related blood metabolites, offering a targeted strategy for prevention in susceptible individuals.

Researchers have identified a potential biological marker for the effects of psychotherapy on depression. A new study reveals that cognitive behavioral therapy is linked to increased gray matter volume, demonstrating a physical brain change similar to effects seen with medication.

Belief in reincarnation is common in many cultures, but how do adults who claim past-life memories fare psychologically? A new Brazilian study, published in The International Journal for the Psychology of Religion, links these experiences to distress but also to...
