I’m not sure this is correct. If someone is managing their ADHD it doesn’t mean they don’t have it.
Yes, many individuals with ADHD can cope without medication and may go on to live good-enough lives that might be the envy of others. However, there may be a lot of potential being left on the table staying untreated.
So to say that someone clearly doesn’t have ADHD because they don’t have a rep of reckless driving tickets because of impulsivity lapses is a bit of a slap in the face for many who still do, but developed compensation strategies to some extent.
While ADHD has a large part to play in causing mental illness, and is often misdiagnosed as bipolar, BPD, anxiety, etc, ADHD in itself it is not a mental illness, but a disability. I know this is somewhat a semantic debate, but it is important.
"If someone is managing their ADHD it doesn’t mean they don’t have it."
So someone who is managing their ADHD via medication doesn't have it? What about changing their occupation to one where intricate planning is no longer required of them, so they cease to be constantly failing?
Someone can have ADHD and have it impact their life to a much greater or lesser extent based purely on the life situation they are in.
You are born this way. Such as someone on the ASD spectrum.
