My 46 year old sibling displays numerous signs of being on the spectrum and while I am not an expert I do work in an SEN school and have taught numerous autistic young adults. The experiences they describe to me and their behaviour suggests to me a very high probability of being on the spectrum. They are struggling emotionally and so I wonder if a diagnosis might help them navigate their life better, feel happier and have greater understanding of self? Perhaps it would even encourage them to seek out mentoring as well (which has really helped some of my adult students). However, this is of course a delicate issue to address, and perhaps not my place. Any advice of someone who has experienced something similar. (I am not practice of diagnosing people as I am not fully trained but I am as sure as I can be that they are on the spectrum. One other close family member also thinks this is very likely.) They are dyslexic (severely and diagnosed) and self-diagnosed ADHD.
