Maladaptive Daydreaming was seen to feature in a developmental disorder called Cognitive Dissociation Syndrome. The best description is from its main researcher, Prof Russell Barkley:

This includes some of these symptoms:

1. I am slow at doing things.
2. My mind feels like it is in a fog.
3. I stare off into space.
4. I feel sleepy or drowsy during the day.
5. I lose my train of thought.
6. I am not very active.
7. I get lost in my own thoughts.
8. I get tired easily.
9. I forget what I was going to say.
10. I feel confused.
11. I am not motivated to do things.
12. I zone out or space out.
13. My mind gets mixed up.
14. My thinking seems slow or slowed down.
15. I daydream.


Just wanted to put it out here, if anyone feels this is familiar. The youtube series is very good, strongly recommend watching it. CDS is different from inattentive ADHD, however, it was long confounded with it.
