Hyperbaric Oxygen Therapy Shows Promise for Treating PTSD

Hyperbaric oxygen therapy (HBOT) has shown effectiveness in alleviating symptoms for individuals with PTSD unresponsive to traditional treatments. In a study of combat veterans, HBOT led to significant reductions in flashbacks, irritability, and hypervigilance, and was associated with improved brain connectivity on fMRI scans. The specialized protocol, developed over years, involves 60 sessions of breathing pure oxygen under high pressure.

Astrocytes Play Role in Deciding the Fate of Memories

Researchers have uncovered a surprising role for astrocytes—cells surrounding neurons—in deciding which memories are kept or forgotten. By manipulating astrocytes in mice using optogenetics, scientists found that acidifying these cells after a traumatic experience leads to forgetting the memory over time, while alkalinizing them preserves it long-term. This suggests astrocytes significantly influence emotional memory retention and could inform treatments for conditions like PTSD.

Mother’s Role in Buffering Child PTSD

A mother’s ability to regulate her response to trauma can significantly lessen PTSD symptoms in her children, particularly in high-stress regions. The research observed 131 mothers and young children in southern Israel, where security threats are prevalent, linking maternal self-regulation to reduced PTSD in children.

Why PTSD Develops in Some but Not Others

Fear memories initially form broad associations, but over time, they shift to become episodic memories tied to specific timelines. This process involves the hippocampus early on, with the dorsolateral prefrontal cortex integrating the event sequence later.

Child Trauma Recovery Tied to Thoughts, Not Event Severity

A new study reveals that how children mentally process traumatic events is the most significant factor in predicting their mental health outcomes, including PTSD, anxiety, and depression. Cognitive factors—like how children remember the event and view themselves afterward—play a more critical role than the event’s objective severity. Researchers found that children with more negative self-perceptions or distorted memories were at higher risk for long-term psychological impacts.

New Brain Stimulation Target Could Treat PTSD

A new study suggests that neurostimulation targeting specific brain circuits may help treat PTSD in veterans. Researchers found that veterans with damage to brain areas connected to the amygdala, the brain's fear center, were less likely to develop PTSD.

AI Detects PTSD From Social Media Posts

Researchers analyzed millions of tweets to identify COVID-19 survivors at risk for post-traumatic stress disorder (PTSD). By applying machine learning techniques, they achieved an 83% accuracy rate in classifying posts as PTSD-positive, based on specific keywords related to trauma symptoms.

Observing Trauma Boosts Resilience Through Serotonin

A new study reveals that observing others endure trauma can increase resilience and protect against depression. Researchers found that serotonin, released in the brain's habenula, plays a key role in this process, enhancing resilience by altering neuronal activity.

Brain Control of Escape Behavior May Unlock Anxiety Treatments

Researchers discovered how the brain controls sensitivity to threats, influencing escape behavior in mice. The study found that inhibitory neurons in the periaqueductal gray (PAG) regulate both the initiation and termination of escape.

Exercise Aids Memory Erasure in PTSD

Increased neuron formation in the hippocampus, stimulated by exercise or genetic manipulation, helps mice forget traumatic or drug-associated memories. This process involves rewiring neural circuits, disrupting the recall of fear memories. These findings offer potential new approaches for treating mental health conditions like PTSD and drug addiction.
