While optimism is often celebrated, a new study reveals that excessive optimism can lead to poor decision-making, particularly in financial matters. The research shows that individuals with high cognitive ability tend to be more realistic and pessimistic in their future expectations, while those with lower cognitive ability lean towards excessive optimism.
A new study reveals an increase in cannabis use among older Americans, with 12% reporting THC-containing substance consumption in the past year, a rise from pre-pandemic levels. The study highlights a connection between high-risk alcohol consumption and increased cannabis use in this age group.
A new study reveals a significant association between adverse childhood experiences (ACEs) and symptoms of muscle dysmorphia in adolescents and young adults. The research highlights how ACEs, such as domestic violence and emotional abuse, can lead to the pathological pursuit of muscularity as a coping mechanism.
A new study highlights the significant role of imagination in evoking empathy and driving prosocial behavior. While empathy is multifaceted, this research focuses on two aspects: personal distress and compassionate concern. The study reveals that vividly imagining someone else's problems increases personal distress, motivating individuals to offer help.
Alcohol, the world's most common addictive substance, leads to $249 billion in annual costs and 88,000 deaths in the U.S. Alcohol use disorder affects millions but is under-treated. Researchers discovered a key player in alcohol addiction: pituitary adenylate cyclase activating polypeptide (PACAP).
Researchers utilizing artificial intelligence (AI) to analyze brain MRI scans have identified significant differences in white matter tracts of adolescents with ADHD. The study, involving over 1,700 participants from the multi-institutional Adolescent Brain Cognitive Development Study, used diffusion-weighted imaging (DWI) and a deep-learning AI model to detect these variations.
A new study reveals distinct differences in brain activity between traumatic memories in PTSD patients and regular sad autobiographical memories. This research, the first of its kind to examine real-life personal memories, found that traumatic memories do not activate typical memory-related brain regions like the hippocampus, suggesting they're not processed as regular memories.
A new study reveals a significant link between individuals' musical tastes and their moral values. Employing machine learning to analyze lyrics and audio features from participants' favorite songs, the study found that music preferences reflect specific moral dimensions.

These research articles involve depression, seasonal affective disorders, grief, pain, sadness, happiness and generally news regarding mental health research.

Researchers discovered that chronic stress induces depression-like behaviors in fruit flies, Drosophila melanogaster, affecting their motivation and activity. The study found that Ayurvedic medicinal plants, particularly Withania somnifera (ashwagandha) and Centella asiatica, can improve the flies' resilience to chronic stress when used prophylactically.
Researchers discovered a link between depression and reduced taurine levels in the hippocampus, a key brain region for memory and learning. Using advanced 7T MRI technology, researchers found significantly lower taurine concentrations in the hippocampus of young females with depression compared to healthy controls.
New findings reveal key genetic and cognitive factors linked to depression. Research shows genetic variants affecting brain structure in adolescents, enlarged brain regions related to emotion processing indicating early intervention targets, and how depression more severely impacts reasoning in older adults. Additionally, unique epigenetic markers in blood samples of depressed adolescents have been identified, paving the way for more effective, personalized treatments.
Emerging research underscores the profound connection between mental health and heart disease, with depression and anxiety hastening the onset of cardiovascular risk factors. Findings from two preliminary studies suggest that psychological conditions not only distress the mind but also have tangible effects on physical health, potentially leading to heart attacks or strokes.
