Asperger's Syndrome is not temporary. Do not lightly suggest things.
Most often, people like to imagine things. They also may develop ticks when they are overly anxious. They can develop into OCD-like symptoms that will disappear with time once they are less anxious, or they can persist in less degree when people feel anxious.
These are all just "features" that the nervous system that people have. A way for people to cope with stress. Does that mean it becomes pathological? In some cases, yes. Then you'd be calling OCD. When it does not become pathological, you simply do not bother going to a doctor and having them diagnosis you into one of the many disorders that one can have.
Errr... in regards to everything but the top line, no.
OCD is also not something that's temporary. It is every single bit as permanent as Asperger's Syndrome, and the only real difference is that it's one people are more likely to play around miss-diagnosing themselves with. However, I have worked with people who have OCD, and it is the sort of thing that makes a person effectively non-functional.
As such, if people are functional but get caught up with things, particularly things that have to do with information rather than behaviors (such as grammar or getting something factually wrong in a minor way,) then it's far more likely to be Asperger's than OCD, if anything.
Also, anxiety-induced OCD-like symptoms is not actual OCD.
