Every person is different and their response to mental health disorders will be different as well. Do you have more specific questions about this subject?

Is the hallucinations a symptom of the schizophrenia ?
Or
Is the hallucinations is the ambiguous characteristics of the cause ?

Practicaly,what is different if we deal with the hallucination as if it is
a symptom ,and as if we deal with it as the characteristics of the
actual cause ?

Hallucinations are frequently associated with schizophrenia. Hallucinations are a common feature of bipolar disorder as well. It is only one feature of the disorder. Other symptoms would need to be present in order for a diagnosis of schizophrenia to be given.

You ask about treating the symptoms or dealing with the symptom as a characteristic of the cause of the disorder. A characteristic of a disorder is a symptom. Mental health disorders are treated by symptoms. This is due in part to our limited understanding of the disorders and our limited arsenal of options for treatment.

What is the actual cause or etiology of schizophrenia? In some cases we don't know. In some cases it is due to a neurotoxin that is affecting neurological processes. One example of this is toxoplasmosis. It is know to cause schizoprenia in some people who are sensitve to the organism that causes toxoplasmosis. It is expressed in the person as schizoprhenia. Having this knowledge does not alter the treatment though. You treat the symptoms.

I am not sure I have adequately answered your querie. Have you broached this subject with your doctor?

The hallucination is not obvious symptom for the outer earwitness or eyewitness !
You can not hear the voices which the schizophrenic heard it,either
by you ears or by any scientific instruments.
You can not see the imaginary people which the schizophrenic see their ,
either by your eyes or any scientific instruments.

Simply:how can you know that there is someone suffer from the
hallucinations while he is deaf ?
Then,the credibility is related the testmony of the schizophrenic oneself
not the observations or the scientific test !
Because ,in anyways,you see and hear nothing !

While the hallucination is the main event of the whole case.
The hallucinations are perior and cause to the behavioral and
existential events.

The hallucinations in itself is not organic or mental symptom but it is
the characteristics of the cause itself.
Because the hallucination does not happen by the action of the
mental functions or beain processes

Trusim,if the hallucination is a mental symptom.

If fact,on the individual level and the mental functions mechanism,
the person does not find out any mental mechanism responding
to the self volition to stop the production of hallucination processes !
Always,the self volition is fail to stop the hallucinations emergence !

If the hallucination is an organic symptom.
There is no any drug be able to remove the hallucinations or even the
ability to stop the cultural changes in the person's ideology !

By any logic you consider the hallucination is a symptom of mental
illness or even brain disease ?
While you in the same time unable to know the internal world of the
hallucination itself directly by your eyes or any scientific means !

Simply,the hallucinations has been manifested itself as a mental/emotional
perceptions without stimulus in the external environment or in the internal
biochemistry because it is acquired symptom !

That is to say,the total of hallucinations is inspired symptoms because it is
the characteristics of the hidden cause who is manifest itself through
the internal symptom of the thing which so-called hallucinations.

That is to say,the hallucination is the characteristics of the cause which
reflected as a perceptions !!!
Simply,look at the descriptive expression of any schizophrenic when he
speak about the nature of the hallucinations[the imaginary people
and the heard voices] ,wherever the person believe that he is not
imagine the pictures or speak with oneself !!
