Measurable Gains in PTSD Using Psychedelics
Posttraumatic stress disorder disproportionately affects military veterans. Lifetime PTSD prevalence among U.S. veterans is about 9.4 percent, and current PTSD affects roughly 5 percent of veterans in a given month. Among veterans using VA health care , lifetime PTSD rates can exceed 20 percent, with some Iraq and Afghanistan combat cohorts reaching 20 to 23 percent. These rates reflect repeated combat exposures, trauma intensity, and operational stressors unique to military service. Research is also examining how repetitive low level blast exposures during training, weapons firing, and combat contribute to distinct brain changes. Blast exposure is linked to traumatic brain injury and long term cognitive and mood symptoms overlapping with PTSD. Even low level blasts can cause tau protein accumulation and neurodegeneration similar to chronic traumatic encephalopathy , affecting memory, emotional regulation, and stress response. These subtle changes may amplify PTSD symptoms, complicat...
