Yeah, women with ADHD frequently had been misdiagnosed as being depressed
And people who have what used to be called Aspergers (now ASD) and were born before the 2000's were frequently misdiagnosed as these:
ADHD- Now ADHD is frequently comorbid to autism. About 20-50% of people who have ADHD also have ASD. And about 50-70% of people on the autism spectrum have ADHD.
PDD-NOS- Like Asperger's, this was removed in 2013 and replaced with the term "autism spectrum disorder."
Bipolar- This is also frequently comorbid to ADHD and ASD. A lot of women with ADHD were also misdiagnosed with Bipolar.
Borderline Personality Disorder- Also frequently comorbid to ASD and ADHD. A lot of women with ADHD were also misdiagnosed as Borderline.
Believe me, I got diagnosed with a crap ton of things years ago (and some of it I did not find out about until I was an adult) before I got my Asperger's (now ASD) dx as an adult in 2011:
ADD
Sensory Processing Disorder
Auditory Processing Disorder
Dyspraxia
OCD
NVLD (Nonverbal Learning Disorder)
Tinnitus
Depression
Anxiety
Executive Functioning Disorder
The only thing that doctors did back then for ADD/ADHD was keep adjusting and changing your medications to the point where none of the medications work anymore.
Edit: I forgot to mention that when the DSM-IV came out in 1994, it was ruled that autism and ADHD could not be comorbid to each other. However, this stance changed with the DSM-5 in 2013.
