Many may also resist treatment, arguing that there is nothing wrong with them.


Major symptoms include:

Delusions,  the patient fears he’s being persecuted and/or has delusions of grandeur
Hallucinations,  hears voices and/or sees, feels, tastes, or smells things that are actually non-existent
Thought disorder, jumps from one subject to another for no logical reason. The speaker is erratic
Lack of motivation, the patient has no drive. Everyday activities such as hygiene, are neglected.
Social withdrawal, avoids social interaction, has no friends
Unawareness of illness,  as the hallucinations and delusions seem so real for patients, many of them may not believe they are ill. They may refuse to take medication for fear of side effects, or for fear that the medication may be poison, for example.
Cognitive difficulties,  the person can not concentrate, recall things, plan ahead, is generally disorganized

    Ziprasidone (Geodon) – the risk of weight gain and diabetes is lower than other atypical antipsychotics. However, it might contribute to cardiac arrhythmia.
    Clozapine (Clozaril) – effective for patients who have been resistant to treatment. It is known to lower suicidal behaviors in patients with schizophrenia. The risk of weight gain and diabetes is significant.
    Haloperidol – an antipsychotic used to treat schizophrenia. It has a long-lasting effect (weeks).
