I personally have experienced mania many times, and it is associated with a surge in dopamine, and I love how I feel with that dopamine surge. I feel so alive, but I have never been in the depressed bipolar phase, the total lack of feeling. I have felt badly sure, but not suicidal. I have never even for one second felt like killing myself.
The term then for feeling one part of the bipolar spectrum is unipolar. And the thing I hate about "mental illness" is people consider it this permanent condition while physical illness comes and goes. In reality, we all slip in and out of mental illness (depression, anxiety) all the time, and I slip in and out of unipolar mania quite a bit but unfortunately much, much less now that I am older. I am actually making prudent financial decisions now instead of my previous "drinks for everyone... on me" personality. Sigh.
Bipolar disorder, autism, and ADHD all involve high glutamate levels which is what drives the hyperactivity, but dopamine levels vary with each condition. Bipolar is high dopamine, Autism is normal dopamine, and ADHD is low dopamine.
I don't think it is possible for ESTPs to have ADD/ADHD because we are so dopamine driven. As you move up the education spectrum, there are fewer Ss and more Ns, and with rare exception, most of the Ns would put me to sleep. If I were nodding off and some N professor questioned me about having ADD today, I would respond, "I don't have ADD. You are just boring." I wonder how many ESTPs with "ADD" are just bored.
The drugs for ADD raise dopamine, and when you raise dopamine in anyone, you get more focus and test scores go up. However you can also induce mania with these dopamine raising ADD drugs, and I don't think most doctors or health professionals get that.
The combination of dysgraphia and bipolar intrigues me. I have seen dysgraphia with autism a lot, but most bipolars I know write fine. Maenad, what is going with you and the dysgraphia? Does it hurt to write?
