Simple question:
In general,what is the schizophrenia ?
It seems very easy to answer,but you will find that all possible answers are irrelevant -why !
It is supposed that,if you know the correct answer,your answer content should be a clear description for the cause itself nothing else !
To understand the issue;
there are 3 common questions asking ;
1-In general,what is the genetic disease ?
2-In general ,What is the viral disease ?
3-In general ,What is the bacterial disease ?
In the case,if you know the genetic disease,your answer content will be a clear description to the gene (the cause), you will taking about the structure and function of the gene ,and its functional role in the development the fit/mal health condition (disease)
The health condition which be called a disease ,is the result of the functional behavior of the gene (the expressions).
in other words,the patient gene is the body structure of the disease condition ,or the patient gene (what you call -defective gene) is the disease substance in the anatomical structure
In the case,if you know the viral disease,you will talking about the virus (the cause),its life circle in the host cells,and its functional role to development the bad health condition (the disease) ,whereas the virus body is the substance of the disease inside the anatomical structure of the host
Now,we asking;
In general ,what is schizophrenia ?
it is supposed that,your answer content is a clear description for the (X) cause (structure/function),and its functional behavior to development the health condition which be called (schizophrenia), whereas the cause body has represents the substance of the health condition (Sz) in the human nature ,
,If you think sz is a disease condition ,you should speaking about the cause itself to let us know the class,category,division , group …etc of this condition
In the case,if you say,sz is a genetic disease,you should talking about specific gene (defective) who is responsible to development the sz health condition (disease) ,and proof that there is a causality relationship between bad expressions of defective gene and all types of symptoms
In real world, most people belief that,sz is genetic disease without finding any defective gene .as if they are believing with ghostly Gene have no visual organic structure in the bodies of all schizophrenic individuals !
First of all,find the defective gene,second, proof the causality relationship between it and all symptoms of sz ,then you can say: sz is a genetic disease !
