At first,before searching about relationships,we want to know ;
When does the phenomena be called cognitive deficiency occurs in a person diagnosed with SZ ?
1-Was the person suffering from cognitive deficits before the Sz occurred ?
if you say yes,then the sz has no role in the cognitive deficits !
OR
2-The person suffered from cognitive deficiency immediately after the occurrence of the sz,and that suffering continued for an indefinite period time despite the improvement manifestations in his personal perception that the person felt through all types of therapeutic means
In the second case,the manifestations of cognitive deficiency arise as a result of the negative influence of the casual factor on the Cognitive Processes that precede behavioral outputs which fulfill the desires and living requirements
The question;
What is the casual factor (schizophrenic factor) ?
There is no certain belief in a Single casual factor,rather, there is a theoretical belief in a multiplicity of casual factors except the real actual casual factor (the thing be called hallucination) ,because it is a spiritual emitter be unknown to the materialist scientists
