Lifetime Opioid Exposure and Neurocognitive Performance Among a Sample of Combat Veterans With and Without Mild Traumatic Brain Injury

Although lifetime opioid exposure did not appear to be significantly associated with neurocognitive performance among this sample of Veterans, there are indications that the relationship between opioid exposure and neurocognitive function is modified by deployment-related mTBI history. Continued research exploring the interplay between mTBI and opioid exposure on neurocognitive performance is needed.
