MOGAD masterclass in Berlin: interesting and dynamic talks on what we know and where we need to go. @ikerelosua attending and @EoinFlanagan14 @marignierro @darshi_r @mlevy18 @SaraMariottoMD @chenmayo and many more! @cemcat_em
Check out our Neurology Podcast with @JRAbbatemarco and @Smathorn on our international retrospective study on PLEX for MOGAD attacks.
Early PLEX = 👍, but need a trial to prove it. Look out for the TIMELY-PLEX trial that will start enrolling this fall!

This case highlights that venous stasis retinopathy can occur in MOGAD, which is believed to be due to the profound optic disc edema and/or inflammation of the optic nerve and sheath leading to compression of the central retinal vein: hubs.la/Q03FZj8m0

Misapplication of the 2015 criteria for neuromyelitis optica #NMOSD is common, and alternative explanations in seronegative #NMOSD should be considered, including multiple sclerosis and functional neurologic disorder.

The US #MOGAD patient summit was a success! If you joined us, please post your photos with #USMPS2025!
We were thrilled to hold our inaugural event on August 16, 2025. It was the first event with a full day of MOGAD with @EoinFlanagan14 , @chenmayo & their staff along with 200 MOG patients, caregivers & family members in attendance. Plenty of networking, learning & crazy fun happening!
Thank you to our sponsors @UCBUSA , @Roche and @genentech as well as the entire stuff at @MayoClinic , MOGAD clinic. #NeuroTwitter 👁️🧠🥼🧪

Very nice study comparing sensitivity and specificity of live vs fixed CBA for AQP4 and MOG Ab detection in clinical practice. Live CBA offers a big gain in sensitivity and help not miss real cases with the disease! onlinelibrary.wiley.com/doi/… @ESotirchos @EoinFlanagan14 @chenmayo
