Hello,
I am in a similar boat. The two schools I am applying to don't require the Personal History Statement (the Statement of Purpose is required) and they want me to discuss my diversity and how I would help others with my degree.
Ideally, I would want to discuss my learning disability but they are so taboo in schools that I worry about how a PI would take this. I would discuss how I ultimately want to work in academia and help formulate course materials that are appropriate for neurodiverse students and how I have worked with students diagnosed with learning disabilities and used skills I've learned for myself to teach these students.
Overall, I see it as a positive, but I am worried that I'll be stigmatized based on this even though I don't plan on asking for any accommodations.
I would love anyone's opinions or thoughts on this!
