Persistent Post-Concussion Syndrome Following Motor Vehicle Collision: A 27-Month Longitudinal Case Study of Multimodal Rehabilitation

Vollständiger Abstract

Worum geht es in dieser Arbeit?

Persistent post-concussion syndrome (PPCS) develops in 10 to 30 percent of patients following mild traumatic brain injury (mTBI), yet the most effective management approach remains an open question. This report describes a 37-year-old female who sustained a motor vehicle collision and was followed prospectively over 27 months. Structured evaluation at baseline identified dysfunction across oculomotor, vestibular, autonomic, cognitive, and neurophysiological domains. An intensive multimodal rehabilitation programme was associated with an 86 percent reduction in symptom burden (Post-Concussion Symptom Scale: 80 to 11) by the six-month mark. Thereafter, symptoms gradually returned in spite of continued treatment, and at 27 months the patient still reported moderate-to-severe headache (6 to 7 out of 10), persistent dizziness (5 to 6 out of 10), and meaningful functional limitations. The trajectory observed here, marked by initial gains followed by progressive relapse, illustrates the fluctuating and often incomplete recovery seen in a subgroup of PPCS patients. Clinicians should anticipate this pattern and frame outcome expectations accordingly, while building sustained, adaptive management strategies into long-term care plans.
