Pharmacologic and Nonpharmacologic Pain Management in Patients with Traumatic Brain Injury: A Multidisciplinary...

Area of Science:

• Neuroscience
• Pain Medicine
• Neurology

Background:

• Traumatic brain injury (TBI) is a significant cause of neurological disability worldwide.
• Persistent symptoms post-TBI include cognitive, mood, sleep, and autonomic issues, with chronic pain being particularly debilitating.
• The development of chronic pain after TBI is multifactorial, involving initial injury, neuroplasticity, neuroinflammation, and psychological factors.

Purpose of the Study:

• To review the complex pathophysiology of pain following traumatic brain injury.
• To outline a multidisciplinary management framework for post-TBI pain.
• To discuss current and emerging treatment strategies for chronic pain after TBI.

Main Methods:

• Classification of pain syndromes using the International Association for the Study of Pain framework: nociceptive, neuropathic, and nociplastic pain.
• Review of pharmacologic treatments (anti-inflammatories, anticonvulsants, antidepressants) and non-pharmacologic strategies (physical therapy, CBT, neuromodulation).
• Exploration of emerging innovations including machine learning, blood biomarkers, and neuro-reparative agents.

Main Results:

• Post-TBI pain often presents as mixed phenotypes, driven by neuroinflammation and central sensitization.
• Pharmacologic treatments require careful dosing due to TBI comorbidities.
• Non-pharmacologic therapies are crucial for addressing biomechanical and psychosocial aspects of pain.

Conclusions:

• Effective management of post-TBI pain necessitates an integrated strategy.
• Mechanistic pain classification, multidisciplinary care, and advanced diagnostics are key to personalized treatment.
• Future directions involve leveraging technology and biomarkers for improved prognostication and treatment.
