This article, the first in a series, explores the often-overlooked psychiatric injuries resulting from motor vehicle accidents (MVAs), focusing specifically on Post-Traumatic Stress Disorder (PTSD). Defined as the somatic and cognitive effects of psychological trauma, PTSD can manifest in anyone who has experienced or witnessed threatened death or serious injury. Statistics show that 11% to 33% of MVA survivors meet the criteria for PTSD, yet symptoms may not fully develop until the fourth week following the incident.

The sources identify four primary symptom clusters: intrusion, avoidance, negative mood alterations, and changes in arousal. Furthermore, certain physical conditions like concussions and post-concussion syndrome significantly increase the likelihood of a patient developing PTSD. To aid in early identification, the article recommends that chiropractors implement a standardized, downloadable questionnaire starting at the four-week mark post-accident. By recognizing both the physical and psychophysiological impacts of an MVA—including dissociative symptoms like depersonalization—chiropractors can better manage the comprehensive recovery needs of their patients and refer for psychiatric care when necessary.
