Constantly Thinking Disorder: is it a real thing?

I've never heard of it under that name. You may be referring to ADHD or OCD.

To call constant thought a disorder would be a stretch in my opinion, but in my personal experience I myself am constantly thinking and processing new ideas and information. I find that it improves my mood and that I am often bored if I'm not doing two or three things at a time, and so far it has not caused a problem in my life in the slightest.

This may be connected to anxiety. There are many types of anxiety. Some of the side effects of anxiety may include racing of thoughts. Check in with te Doctor to see if you might have clinical anxiety.

Yes I think constantly thinking is a real disorder because it might also be partially anxiety because you can't turn your mind off and can't stop overthinking and worrying

I do believe that Constantly Thinking Disorder is a real thing. Based on my personal experience, I've had times in my life where it was though I couldn't "shut-off" my brain. As expected, this causes anxiety, worry and lack of sleep. It's as if I was trying to stay one step ahead or if I just had so much worry and anxiety that I could not turn it off in my mind. It caused me to not appreciate life to its fullest, as much joy was replaced by worry.

This isn't a "real" thing it isn't in the current DSM-V. But it can be apart of other disorders such as Generalized Anxiety or OCD

Yes, its a real symptom but the name of the disorder may be different. Maybe in the anxiety category where the person is hearing voices or worries non stop about what will happen, etc.

Probably, some people might call that "imagination". Just don't let it distract you too much, find a way to channel all that brainpower.

If it is I have it. It might be apart of adhd. I looked it up and there is a continuous thinking disorder so maybe

I do not believe this is a real disorder, just a large problem amongst most people. I believe it falls under anxiety and relates as a symptom: over thinking, excessive thinking, constant thinking, etc. But it, in itself, is not a disorder.
