8 dsm 5 criteria for PTSD driver#

The bus driver and an older student worked frantically during the night to dig their way out and move a heavy manhole cover blocking their exit, as the trailer roof began to cave in. Three men hijacked a school bus at gunpoint, drove it 100 miles away, and forced the bus driver and 26 children down a hole into an old trailer that had been buried 12 feet underground. It was a school bus kidnapping in Chowchilla, Calif., in 1976 that changed the long-held notion that children were resilient to trauma, Herringa said.

Put together, recent imaging studies show a “fairly consistent pattern of developmental decline in adaptive or healthy functioning in the brain, particularly in the emotional regulatory and threat response systems,” Herringa said, adding that more study is needed. That connectivity is critical in helping regulate emotional responses and allowing youth to benefit from exposure therapy, he added. Other brain imaging research by Herringa and others that followed youth aged 8 to 18 has uncovered other differences: Over time youth with PTSD experience regression in normal brain development, namely decreased hippocampal volume, increased amygdala activation, and decreasing prefrontal-amygdala connectivity.

In fact, researchers found that the brains of girls exposed to abuse may habitually utilize threat-related circuitry, even when they’re in a safe setting. BBRF is the world’s largest private funder of mental health research.īrain scans of girls who had suffered abuse showed delayed maturity in the emotion circuitry of their brains, which was associated with increased hyperarousal symptoms, one of the hallmarks of PTSD, according to a study by Herringa and colleagues in The American Journal of Psychiatry in 2021. As such, effective recovery from pediatric PTSD may involve helping youth restore their brain’s threat circuitry and executive function, Ryan Herringa, M.D., Ph.D., director of the Division of Child and Adolescent Psychiatry at the University of Wisconsin School of Medicine and Public Health, said at a webinar hosted by the Brain & Behavior Research Foundation (BBRF).
