Chronic Pain Linked to Treatment-Resistant Depression in Brazil
A study published in the journal Nature Mental Health on 28 April argues that many patients classified with treatment‑resistant depression may actually be experiencing unmeasured chronic pain, which can diminish antidepressant response. The researchers note that current definitions of treatment‑resistant depression do not require assessment of pain, and that widely used rating scales such as the PHQ‑9 and Hamilton Depression Rating Scale do not directly evaluate pain burden.
One of the authors, Nilson Mendes Neto of Harvard Medical School, explains that there is a crucial difference between a doctor simply knowing a patient feels pain and having a structured measurement of that pain incorporated into the evaluation. He says, “Today, the classification of treatment‑resistant depression is based mainly on failure of adequately dosed antidepressant trials; the presence, intensity and functional impact of pain are not part of the formal definition.” The authors recommend systematic pain screening in Brazil’s public health system (SUS) and stress that patients should not alter or stop their medication based on these findings alone.
