Pivotal Protein in Female PTSD Identified

Researchers discovered an exciting new role for a widely known protein, ubiquitin, particularly in its K-63 form. They found K-63 ubiquitin selectively influences fear memory formation in female brains, potentially contributing to post-traumatic stress disorder (PTSD). This discovery sheds light on why women are more likely to suffer from PTSD and paves the way for developing female-specific therapeutic treatments.

Discovery in Zebrafish May Yield Better Understanding of a Range of Mental Health Disorders Related to Stress and Anxiety

Deficiencies in DSCAML1 disrupt normal brain development and increase baseline levels of cortisol, making the hormone less able to function correctly during periods of stress. The findings shed new light on programmed cell death in the developing brain and could lead to new treatments for mental health disorders including stress and anxiety.

Why PTSD Patients Relive Highly Charged Fear Memories in Sleep

In people with PTSD, during REM sleep norepinephrine and serotonin levels remain high, reducing the brain's ability to inhibit fear-expression neurons through neural rhythms sent between the prefrontal cortex and amygdala. Those with PTSD require higher frequency rhythms to extinguish fear memories. Researchers say unlocking the higher frequencies via therapies could help to restore quality sleep in those with PTSD.
