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! [ https://t.co/k01D4FNK6E]

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: https://t.co/zCHJjUXgKi #NeuroImage #NeuroX

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. Study from @chenmayo @MayoClinic▶️ https://t.co/pB75p1eTgv
