A scientometric analysis of 42,170 publications on posttraumatic stress disorder (PTSD) from 1945 to 2022 identified four major research trends: war veterans and refugees, treatment of PTSD/neuroimaging, evidence syntheses, and somatic symptoms of PTSD. The largest cluster focused on evidence synthesis for genetic predisposition and environmental exposures leading to PTSD. War-related trauma research has shifted from battlefield in-person exposure to drone operator trauma and is being outpaced by civilian trauma research, including the COVID-19 pandemic, postpartum, and grief disorder. Recent trends show a burst in PTSD treatment research involving Mhealth, virtual reality, and psychedelic drugs. The USA dominates collaboration networks, with a recent surge of publications from China. Compared to other psychiatric disorders, there is a lack of high-quality randomized controlled trials for pharmacological and nonpharmacological treatments.
