About the author
Ayan Kalra was diagnosed with Myelin Oligodendrocyte Glycoprotein Antibody Disease (MOGAD) in 2023 after experiencing sudden vision loss caused by optic neuritis. At just 12 years old, he found himself navigating hospital stays, medical tests, and a diagnosis that even many healthcare professionals rarely encounter.
Determined to help other patients and families facing the same uncertainty, Ayan founded the MOGAD Initiative for Navigation and Direction (MIND). Through educational resources, patient advocacy, and the website mogad.net, MIND works to make MOGAD information accessible, understandable, and readily available to families around the world.
Within months of launching, MIND reached thousands of patients, caregivers, and healthcare professionals across the globe. Inspired by his own experience, Ayan wrote The Gray Cloud at age 15 to help children better understand what a MOGAD diagnosis can feel like and to remind families that they are never alone on their journey.
Today, Ayan continues to advocate for the MOGAD community with one simple mission: ensuring that every patient and family has access to the information, support, and guidance they need—because understanding MOGAD starts here.
