Relationship Between Posttraumatic Headache and Depression After Mild Traumatic Brain Injury

Area of Science:

• Neuroscience
• Psychiatry
• Trauma Care

Background:

• Mild traumatic brain injury (mTBI) can result in persistent psychiatric and somatic symptoms.
• Posttraumatic headache (PTH) and depression are common sequelae of mTBI.
• The relationship between acute PTH and later depressive symptoms requires further elucidation.

Purpose of the Study:

• To establish the association between PTH and depression following mTBI.
• To determine if immediate PTH presence post-injury predicts future depressive symptoms up to 6 months.

Main Methods:

• Secondary analysis of the prospective HeadSMART study data.
• Included 265 adult mTBI patients assessed in the emergency department.
• Utilized Rivermead Post-Concussion Symptoms Questionnaire for acute PTH (aPTH) and Patient Health Questionnaire-9 for depression at baseline and 1, 3, 6 months.

Main Results:

• Patients with aPTH within 24 hours were more likely to experience PTH at 1, 3, and 6 months.
• Acute PTH was associated with more severe depressive symptoms and higher likelihood of clinical depression at all follow-up points.
• Persistent PTH and depression were significantly correlated with initial PTH presence.

Conclusions:

• Acute PTH within 24 hours of mTBI is a predictor of persistent PTH and depressive symptoms.
• Emergency department assessment of aPTH can identify patients at risk for prolonged recovery.
• Monitoring for PTH and depression is recommended for patients with acute PTH post-mTBI.
