PTSD

A study found that ketamine, which causes dissociation, did not increase emotional suppression in PTSD patients. Instead, it decreased brain connectivity involved in emotion regulation.

A single, guided session with the video game Tetris reduced distressing intrusive memories in healthcare workers, with effects lasting up to six months, suggesting a simple, accessible intervention could alleviate trauma symptoms in high-stress populations.

A recent study identified a brain circuit linked to PTSD in veterans and showed that reducing connectivity via transcranial magnetic stimulation correlated with PTSD symptom improvement.

Children who experienced trauma had stronger fear responses to threats, which was linked to increased PTSD symptoms over time. Trauma, not deprivation, affected how they learned to respond to fear.

Researchers found that individuals with PTSD exhibit lower oxytocin and higher vasopressin levels compared to non-traumatized groups. This hormonal imbalance, particularly the vasopressin-to-oxytocin ratio, could serve as a key indicator of PTSD.

A study found that women who developed PTSD after sexual assault showed different brain activity patterns shortly after the trauma, with reduced connectivity in key brain regions compared to those who did not develop the disorder.

A large-scale study has found that women have a higher genetic risk for developing post-traumatic stress disorder, while unique life experiences also play a key role in developing the disorder.

Researchers found that targeting the dorsolateral prefrontal cortex with low-frequency magnetic stimulation can disrupt the consolidation of traumatic memories, potentially offering a new treatment for anxiety and PTSD by preventing the persistence of fear-related responses.

Researchers found that reactivating therapy-modified memories during sleep led to brain changes associated with memory processing, resulting in reduced PTSD symptoms, particularly in avoidance behaviors.

Researchers found that cannabidiol (CBD) significantly reduces PTSD-like symptoms in mice by decreasing brain inflammation through activation of CB2 receptors, suggesting potential new treatments for PTSD by targeting neuroinflammation.

For many combat veterans and trauma survivors, the Fourth of July's fireworks are a distressing ordeal, triggering symptoms of PTSD and anxiety.

Romantic breakups can be potentially traumatic events for emerging adults, triggering symptoms similar to post-traumatic stress disorder.

Canadian researchers discovered distinct brain connectivity patterns in dissociative PTSD patients, revealing hyperconnectivity that likely compensates to maintain global brain function, offering new insights into the neural impact of trauma.

Recent research found that veterans with trained psychiatric service dogs experienced significantly reduced PTSD symptoms, lower anxiety and depression, and improved overall quality of life compared to those receiving usual care alone.

Researchers found that acute stress induces a neurotransmitter switch from glutamate to GABA in the dorsal raphe neurons, leading to generalized fear.
