having no visible emotion
No, hallucinations are a positive symptom. The difference between a negative and positive symptom is that a negative symptom means that something usually present in normal people (affect, social interaction) is missing, while a positive symptom means that something is present in the person that is not present in normal people (hallucinations, delusional thinking).
Psychiatrists or psychologists may associate Type II negative symptom schizophrenia with symptoms such as emotional blunting (reduced emotional expression), avolition (lack of motivation or goal-directed behavior), anhedonia (inability to experience pleasure), and social withdrawal or isolation. These symptoms can significantly impact a person's functioning and quality of life.
Residual schizophrenia is a type of schizophrenia that comes after an active psychotic episode. For the diagnosis of residual schizophrenia to be made, there must be no positive symptom (schizophasia, delusions, or hallucinations).
Cognitive symptom
Schizophrenia is often confused with other illnesses. In fact, some of its symptoms are symptoms for bipolar. These mutual symptoms include paranoia, bizarre delusions, and disorganized speech and thinking. However, if auditory hallucinations are occurring frequently then it is most likely that the person is suffering from schizophrenia. On the other hand, depression is more commonly associated with bipolar disorder and is not a symptom of schizophrenia. Furthermore, schizophrenics do not have 'split personality disorder'.
You are comparing symptoms to a serious mental illness. Schizophrenia is a diagnosis for various types of disorders. Mood disorders and anxiety problems can be a symptom of a schizophrenic's disorder.
Poverty of speech-- A negative symptom of schizophrenia, characterized by brief and empty replies to questions. It should not be confused with shyness or reluctance to talk.
Itching can definitely be considered a withdrawal symptom depending on the addiction. Itching can be a withdrawal symptom from injection drugs for example.
It can definitely be one symptom, but that doesn't mean you have schizophrenia. Check with your doctor first before diagnosing yourself with a mental disorder. But I'm sure if you think you can detect that you have schizophrenia, then you're not schizophrenic.
The plural of symptom is symptoms.
