Repetitive transcranial memory stimulation applied to the dorsolateral prefrontal cortex modifies the negative effects of fear memories. The findings could have implications for the treatment of PTSD. Read More

First responders at the World Trade Center have reduced cortical gray matter thickness, which was consistent with neurodegenerative conditions and evidence their brain age is, on average, ten years older than those of similar ages in the general population. Read More
Pupillary response in those with PTSD differs from people who have not experienced traumatic events. The pupils of those with PTSD failed to show sharp constriction caused by light changes, and more enlargement when exposed to emotional stimuli that other participants. Patients with PTSD not only showed an exaggerated response to threatening stimuli but also to stimuli that depicted positive images. Read More
Hippocampal neurons that respond to fearful stimuli relay that information to the amygdala. These neurons synchronize when memories of the stimuli are later recalled. The synchrony is critical to establish fear memories and the greater the synchrony, the stronger the memory becomes. Read More
In anxiety, neural activity becomes elevated across many specific brain regions, and normal coordination between the networks becomes decreased. Read More
Nitrous oxide may provide temporary relief to veterans suffering from PTSD, a new study reports. Read More
96% of patients hospitalized for coronavirus infections report experiencing PTSD as a result of their illness. Researchers also found an increased risk of depression, anxiety, and other mental health disorders in those hospitalized for COVID-19. Read More
Having difficulty getting to sleep, in addition to ruminating about trauma experiences and other negative events before sleep, boosts the odds of sexual trauma survivors experiencing post-trauma nightmares. Read More
Higher doses of ketamine administered to sheep completely reduced brain activity for a short period. Researchers report as the drug wore off and consciousness was regained, the animals' brain activity switched between high and low-frequency oscillations. The timing of the brain activity corresponds to the time human users report experiencing feelings that their brain 'disconnected' from their bodies after ketamine use. Read More
Cannabis reduces the severity of symptoms by more than half in the short-term for people suffering from PTSD. Using cannabis reduces recurring thoughts of a traumatic event by 62%, flashbacks by 51%, irritability by 67%, and anxiety by 57% for those with PTSD. However, the reduction of symptoms is not permanent. Read More
People with PTSD tend to have higher expression of the SNRNP35 gene in their brains, and lower ZNF140 gene expression in their blood. Read More
New evidence suggests the brain can update poorly formed memories with incorrect information, leading to the creation of false memories. Read More
