New findings linking abnormalities in circadian rhythms to neurochemical to changes in specific neurotransmitters

Researchers at McLean Hospital discovered that individuals with bipolar disorder have altered somatostatin expression in the brain's amygdala, which regulates anxiety and stress response. This altered circadian function is linked to severity of depression and anxiety symptoms, providing potential neural correlates for circadian rhythm ...

What the New York Times gets wrong about PTSD

Drexel researchers found the New York Times' coverage of PTSD from 1980 to 2015 neglected civilian and non-military cases, negatively framing the disorder. This narrow focus can inhibit awareness about PTSD resilience and recovery, and constrain discourse on social determinants of traumatic stress.

Mapping the circuit of our internal clock

Researchers have identified a core group of neurons in the suprachiasmatic nucleus that share information during resynchronization, while those outside this central hub behave like acquaintances. Understanding the SCN's neural network structure is crucial for tackling illnesses like diabetes and posttraumatic stress disorder.

More detailed analysis of how cells react to stress

A new method called 'ADPr-ChAP' allows researchers to identify chromatin sites modified by ADP-ribosylation in response to cell stress, enabling a better understanding of the cellular stress reaction. This breakthrough could lead to new ways of intervening in disease-making processes such as chronic inflammation and cancer.

Stress in adolescence prepares rats for future challenges

Rats exposed to frequent stress during adolescence showed improved problem-solving skills and foraging efficiency under high-threat conditions in adulthood. This study provides insights into how humans respond to adolescent stress and may inform research on human maltreatment and adverse environments.

Newly identified mechanism solves enduring mystery of key element of cellular organization

Researchers at St. Jude Children's Research Hospital have identified a mechanism underlying the formation of stress granules in cells under stress, which are linked to degenerative diseases such as ALS. The study reveals that mutations in proteins involved in stress granule assembly can lead to toxic fibrils and disease progression.

High academic stress linked to increased illness, injuries among college football players

Researchers found that college football players are 3.19 times more likely to get injured during high-stress academic weeks, such as midterms or finals, compared to low-academic stress weeks. The study suggests that coaches and trainers can accommodate practices accordingly to minimize the risk of injuries.

Keep fears at bay by learning something new

Researchers find that presenting a new outcome instead of omitting an expected threat can lead to more effective fear extinction in both rats and humans. The study's findings have implications for the treatment of anxiety disorders, including posttraumatic stress disorder and phobias.

Childhood stress fuels weight gain in women

A national study by Michigan State University sociologist Hui Liu found that childhood stress fuels weight gain in women, while adult stress has no significant impact on men's weight. Childhood family-related stressors such as economic hardship and divorce were associated with rapid weight gain in women.

How cortisol reinforces traumatic memories

A study published in Neuropsychopharmacology found that cortisol enhances the consolidation of emotional memories, particularly in individuals with anxiety and Post-Traumatic Stress Disorder (PTSD). Cortisol levels can strengthen memories of traumatic experiences during both initial formation and reconsolidation after memory retrieval.

For women with bipolar disorder, sleep quality affects mood

Poor sleep quality predicts increased severity and frequency of depression and mania in women with bipolar disorder. For men, baseline depression score and neuroticism are stronger predictors of mood outcome. Improving sleep quality could help patients avoid mood episodes and improve quality of life.

Stress in pet cats -- how it manifests and how to manage it

A recent review highlights the impact of stress on cat behavior and welfare, including changes in exploratory behavior, social grooming, and urine marking. Strategies to prevent or reduce stress include a three-phase reintroduction protocol, environmental enrichment, and breeding strategies that promote well-balanced temperament.

Cancer and chemobrain: Cancer diagnosis affects cognitive function

A new study by Ludwig-Maximilians-Universität München attributes mild cognitive defects in breast cancer patients to post-traumatic stress induced by diagnosis, not chemotherapy side-effects. The study found pretreatment cognitive impairment in breast cancer patients was due to stress associated with the disease.
