I'm 18 and was recently diagnosed with Bipolar 2...though I've been diagnosed with panic disorder and generalized anxiety disorder since I was 12...
My dad has Tourette's, OCD, and ADHD, and he also experiences panic attacks when he isn't smoking or chewing tobacco... he has an extreme over load of Dopamine from having Tourette's syndrome and also from certain drugs when he was in his 20's (which create more receptors for Dopamine in the brain)!
He is ALWAYS hyper. His thoughts race, he is impulsive and spontaneous. Sometimes he goes on these crazy diets, gets very fit, is motivated to run and work out every day, and he is also motivated to take on more responsibilities and it's like he has never ending energy. He and I are extreme extroverts, we think very fast, and I know when I am manic, his everyday characteristics resemble my mania to a T! He also used to have anger problems, which have leveled out now, he's gotten help, but sometimes he gets VERY irritable, and angry because no one can keep up with his mind.
I have noticed some mild depression in him every once in a great while, usually related to situations though.
MY QUESTION: is it possible that his overload of dopamine is causing bipolar? and can bipolar be primarily mania with no psychotic symptoms?
I've done a lot of research on the relationship between TS and BD and I have not found much, which really surprises me! If anyone has more information, let me know.
