Measuring Inflammation in Neuropsychiatric Disorders May Shed Light on Treatment
Meta-analyses have found links between elevated levels of inflammatory markers and many neuropsychiatric disorders, including depression, bipolar disorder, schizophrenia, post-traumatic stress disorder (PTSD) and traumatic brain injury. Multiple studies also show that those with elevated inflammatory markers such as interleukin-1, interleukin-6, tumor necrosis factor (TNF) alpha, and c-reactive protein (CRP) also respond less well to typical treatments than those with normal levels of these markers in the blood.
These links suggest that it could be useful to measure levels of these inflammatory markers in the blood of people who are responding poorly to medications. If one or more of these markers are elevated, it might be a sign that treatment with an anti-inflammatory agent could be helpful. Preliminary studies have shown that some neuropsychiatric disorders may improve after treatment with anti-inflammatory drugs such as aspirin, celecoxib (Celebrex), and the antibiotic minocycline, among others.
