1- Schizophreniform disorder The picture is similar to that of schizophrenia for first four symptom (characteristic symptoms) without the fifth one to be involved (negative symptoms). The duration is usually 1-6 month. The patient with positive symptoms for 1-6 month has a good prognosis because remission is usually expected before 6 months. The social and occupational deterioration is not observed and medical conditions which may cause schizophrenic like symptoms for a limited period of time must be excluded. 2- Schizoaffective disorders This disorder is characterized by a mixture of schizophrenic symptoms and mood affective symptoms (manic symptoms, depressive symptoms, ….. etc) which at least 4 wks to 2 yrs or more. That's to say 4wks( 1 month) of schizophrenic symptoms (hallucination and/ or delusion …. etc) combined with affective mood disorder symptoms (excitement "minia", depression, …etc) must be present to be a "mixed" schizoaffective disorders and can continue for 2yrs or more) 3- Brief psychotic disorder The picture of the positive schizophrenic symptoms lasting for one day to one month with no occupation and social dysfunction or deterioration with exclusion of other condition. The patient returns usually to normal state with very good prognosis. Note: other psychotic and medical disorders must be excluded and also drugs (hallucinogens) must also be excluded. 4- Shared or induced psychosis Here , the patient becomes schizophrenic because he lives with schizophrenic person or has a close contact with schizophrenic friend He gains the schizophrenic feature involuntarily by his close relationship with original patient. Ex. Between the mother and her daughter , the condition is treated by separation of the two with specific Rx of both of them 1 5- Medical condition induce psychosis A certain medical disorder may induce the symptoms of psychotic disorder for limited period of time after which a symptoms disappear 6- Drug induce psychosis The symptoms of psychotic disorder may appear due to either misuse (abuse) of drug or withdrawal of drug. The symptoms that are induced are not related to the drug directly, but occur due to changes in the neurotransmitter at the synapses. Note: certain drugs (with no misuse, abuse or withdrawal) may cause psychotic symptoms (ex: bromocriptine "dopamine agonist") 7- Delusional disorder As we know delusion is a flase belief of morbid origin and is not consistent with his culture or society. There are types of delusions (primary, secondary, …etc) but we want to demonstrate only the following ones: o Bizarre delusion : the delusion can not be believed like patient thinks that his bowel inside his chest ( very strange believes) o Non bizarre delusions: the delusion can be believed by some one who does not know that the patient has delusions . Ex: someone has plan to kill me because I had … etc, someone wants to poison me because I had hurted him previously, … etc We must know and understand the following fact … (delusion disorder are psychotie disorder which are related to schizophrenia in which the patient are not called schizophrenics but patients of delusional disorders which are of types …) while (delusions only (without "disorder") is a symptom which refers to the presence of thought disorder and may be one of symptoms of psychotic disorder like schizophrenia and depression and abnormal personality.
