Constantly Thinking Disorder: is it a real thing?

This is considered a symptom of a larger mental health condition such as anxiety. It is called Rumination whereby an individual thinks obsessively over one particular issue.

We think every second of the day we're awake. How would it be considered a disorder? Over-thinking things may be a sign of some other psychological problems, but isn't 'constantly thinking'.

It's not an official disorder and you will not be able to find it in the DSM or in another manual that diagnoses disorders. But constant thinking could possibly be a consequence of another underlying disorder which leads to excessive thinking. Think about disorders like ADD (a lack of the ability to focus + an overactive mind), general anxiety (eccessively worrying about things till the point that it becomes dysfunctional in your daily life) etc. But hey, it does not have neccessarily be a disorder. Most people seem to live in the now and are fine with that. When you have thoughts constantly running through your head you might think that you have a disorder because you seem so different from the people around you. But it could as well be that your mind is just really well suited for science/philosophy/art etc. So you might even be proud of it!

While Constantly thinking disorder is not real, there are very many disorders characterized by Over-thinking, including many anxiety disorders. Remember, overthinking is normal sometimes, but when it starts to affect your daily life and you can't function normally, that is when it becomes a problem.

I think it falls under general anxiety disorder if I remember correctly; where a person excessively thinks about everything basically, worrying themselves to much. I, myself, suffer with this to some degree. Thinking if I studied enough for an exam, was polite enough to the person I passed earlier today, seemingly basic stuff that most people won't really obsess over. So, yes, it a real thing. Doesn't go by that name to my knowledge but it's something that people can suffer with.

humans are always constantly thinking. It's not necessarily a disorder just because some people have thoughts overflowing in their brain constantly. In my experience there are times when my mind is racing, and times when I cannot muster a thought at all.

I haven't heard about it as a mental illness, but it can be real though. Maybe it is just a part of Obsessive Compulsive Disorder or just overthinking in general.

This is a very real thing. I myself dealt with this when I was around 13, and it consumed me every night as I lay in bed thinking again and again about how I could have done things differently during the day. I feel like people should be more aware that people struggle with this form of anxiety, and that everyone can accept those who face Constantly Thinking Disorder.

I think it is. I also think that it is linked with anxiety related disorders. Because when you have anxiety you can't stop thinking about anything even the small ones like if you locked the door before leaving or if you had said the right thing to a particular person that had happened months ago. Anxiety makes you worry and worry makes you think constantly

I wouldn't say this is a disorder, because your always thinking, somtimes I have conversations with myself in my head, I have this whole character maid up! It's not a disorder though it's very much normal.
