There are many who have both diagnoses, such as myself. ADD (now known as ADHD), in 1990 at age 8. Autism, in 2019, at age 37. Some research suggests a possible connection between both. Perhaps in the near future, when both are taken seriously, a conclusion can be reached on whether they are one and the same.
