ADHD vs Autism: Has anyone experienced misdiagnosis?

I have both, medically diagnosed.

fun fact! there are no overlapping symptoms between adhd and autism according to the dsm 5 but adhd and autism are 60-80 co-morbid

I have heard that autism, ADHD, and OCD are all under the same “umbrella.” Makes sense to me because I find some overlapping symptoms in myself with all of these things.

Yeah so we are pretty certain that while we also have ADHD, we should have also been diagnosed with Autism. Additionally, we're also currently wondering if our tics are a result of a certain form of Autism, rather than Tourettes. ( - Rosie )

So I’ve been diagnosed with ADHD but I’m starting to think I was misdiagnosed and that I’m actually autistic I haven’t yet started trying to figure that mess out as I know it’s hard to find someone to diagnose autism in adults
