Male and female rodents exhibit distinct symptoms and brain features of both PTSD and alcohol use disorder. Following trauma, males show increased GABA receptor function, while females showed increased GABA release. Read More
Increasing time spent sleeping immediately following a traumatic event can help to significantly reduce the effects of trauma. Read More
Sleep deprivation impairs our ability to stop obtrusive thoughts from entering our minds. Read More
Protein synthesis in different amygdala neuron populations is essential for storing information about threat and safety. Read More
People who experience "brain fog" and other neurological problems following COVID-19 infection may be suffering from PTSD, researchers report. Read More
The ability to foster and form secure interpersonal attachments can mitigate some of the genetic risks associated with PTSD. Read More
People with PTSD were more than twice as likely to develop dementia than the general population. Read More
Researchers have identified a key neural circuit that plays a role in dissociation, a phenomenon in which people can feel disconnected from their bodies and reality. Read More
The risk of developing PTSD was eight times higher in teens who experienced traumatic events and had elevated acyl-ghrelin levels than trauma-exposed teens with lower levels of the hormone. Read More
The NTRK2 gene has been implicated in resilience to developing PTSD following psychologically traumatic events. Previous studies outlined the role NTRK2 plays in memory formation. Those with increased regulation of the gene developed fewer traumatic memories following traumatic experiences. Read More
Cannabidiol (CBD) increases cerebral blood flow to areas of the brain associated with memory processing, specifically the hippocampus. The findings identify a potential mechanism for the use of CBD to treat disorders associated with altered memory processing, including Alzheimer's disease, PTSD, and schizophrenia. Read More
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
