Chronic pain impairs cognitive function and increases the incidence of major depression
Current empirical evidence strongly supports the assertion that chronic pain impairs cognitive function across various domains (such as attention and executive function) and is heavily comorbid with major depressive disorder.
The retrieved literature consistently demonstrates that chronic pain conditions lead to cognitive dysfunction and are strongly associated with a higher incidence of major depression and emotional distress. Multiple studies (e.g., papers 0, 1, 3, 4, 7, 10) provide empirical evidence across various chronic pain etiologies showing both cognitive deficits and high rates of depressive comorbidity, directly supporting the claim without any refuting evidence.

This review highlights that chronic pain and major depressive disorder share a high comorbidity rate and bidirectional neural network remodeling that exacerbates functional and emotional impairments.
