It is kind of surprising. I wonder what happens in people who are on anti-TNFa. Maybe the antibody doesn't cross the blood brain barrier though.

I had this question as well. Anecdotally, I've been on various anti-TNFa drugs for the past three or four years, and I feel like my sleep hasn't been impacted (and if anything has improved). Definitely no insomnia. I can nap like a champ!

  It’s suuuuper interesting, right? I tried tossing “tnf-alpha inhibitor insomnia” into Google Scholar. Scanning the results I didn’t feel a “signal” in the papers that TNF-alpha inhibitors cause insomnia—which I wouldn’t expect either due to TNF inhibitor antibody size, right? But! There are tons of very interesting papers in the results behind those keywords. With multiple perspectives. Fruitful combo of keywords, you know? Google Scholar is unusually non-deterministic in what it returns for a given search. You probably won’t see the same papers as I did but it’s an interesting search: https://scholar.google.com/scholar?q=tnf%2Dalpha%20inhibitor%20insomnia https://scholar.google.com/scholar?q=tnf%2Dalpha%20inhibitor... This paper stood out a bit: Inhibition of tumor necrosis factor improves sleep continuity in patients with treatment resistant depression and high inflammation (2015) Authors, full list as I have it in the buffer: Jeremy F. Weinberger, Charles L. Raison, David B. Rye, Amy R. Montague, Bobbi J. Woolwine, Jennifer C. Felger, Ebrahim Haroon, Andrew H.

First thoughts: TNF—alpha signaling becomes unfocused? TNF-alpha release outside the CNS affects receptor sensitivity or other downstream mechanisms that do straddle the blood-brain barrier?
