Women who experience postpartum mood disorders including PTSD, depression, and anxiety two to three years after giving birth had irregular immune system responses, researchers report.
Glutamate neurons in the ventral tegmental area play a key role in the underlying impact of stressors. Silencing the neurons made the brain more resilient to stress.
Social trauma impairs reward function in the brain, making social interaction no longer rewarding and triggering social avoidance.
Augmenting exposure therapy with ten minutes of aerobic exercise reduces PTSD symptom severity for up to six months after a nine-week course of treatment ends.
People with PTSD had a 9% increased risk of hospitalization and an 8% increased risk of death following contracting COVID-19 than people without the disorder. Those with psychosis had a 58% increased risk of death associated with COVID-19, and those with bipolar disorder had a 29% increased risk of dying from coronavirus.
Those with PTSD are almost twice as likely to develop alcohol use disorder than their peers who have not experienced trauma. Researchers report drugs that block FKBP5, such as benztropine, a drug used to control symptoms of Parkinson's disease, and the experimental compound SAFit2 reduce alcohol preference and drinking in models of PTSD.
A new, non-invasive method for measuring cervical nerve activity offers more personal treatments for PTSD and sepsis.
Investigating how psychedelics such as psilocybin act on serotonin receptors, researchers shed new light on how the drugs affect consciousness and assist in treating a range of mental health disorders.
The vulnerability of those with evening chronotypes to anxiety, PTSD, and related disorders may be mediated by altered fear acquisition.
Daily morning blue-lightwave light exposure improved sleep and reduced the severity of symptoms for those suffering from PTSD.
Taking a short nap during the day can enhance memories of disturbing and fearful events, a new study reports.
Exposure therapy for fears and phobias may only have a 50% success rate because fear memories outlast competing safety memories learned from therapy. Researchers investigate the genesis of fear memories and have developed a new mathematical model to help strengthen exposure therapies.
