What symptoms and traits led to your AuDHD diagnoses over just ADHD?

Why did your specialists decide it was both? How did they distinguish for you? For me, I was initially diagnosed with ADHD and Bipolar 2 at 24 years old. When treatment and mdication and therapy and accomodations in my life for those conditions were leading to next to no positive outcomes for me, I explored Autism as a possibility. I had sensory problems with hearing and temperature and RRBs from breastfeeding age that were for emotional regulation and self soothing. My social deficits have never really improved despite immersion, exposure, and great effort to correct them. Also I have many other comirbidities like Asthma, Allergies, Hypermobility and Migraines.
