something i forgot to mention...
I also read somewhere (i think in that same book--surviving schizophrenia) that there might one day be an OCD type for schizophrenia. Right now there are 5 types of schizophrenia:
-paranoid type
-disorganized type
-residual type
-catatonic type
-undifferentiated type

...it said that there might be an obsessive compulsive type in the future because OC-like symptoms are so common in schizophrenia.
Also, i;ve heard numerous times that people with family members who have schizophrenia often develope such things like, anxiety disorders, depression, OCD, schizotypal personality disorder, etc. So there could very well be a relation/connection/link of some kind between schizophrenia and many other mental illnesses.
