"Traumatic Stress Linked to Smaller Cerebellum in Adults with PTSD"

New research from Duke University reveals a significant association between posttraumatic stress disorder (PTSD) and a reduction in cerebellar volume, with individuals with PTSD having cerebellums approximately 2% smaller than those without the disorder. The study, one of the largest of its kind, emphasizes the importance of considering the cerebellum in PTSD diagnosis and treatment, potentially leading to more effective therapies for those affected by the condition. The findings prompt further investigation into whether a smaller cerebellum predisposes a person to PTSD or if PTSD leads to cerebellum shrinkage, with implications for targeting the cerebellum in PTSD treatment.
