How to distinguish between schizophrenia and hysteria Qianlong of: ouyang, 11:50 times
Schizophrenia is a chronic persistent mental illness, the cause has not yet entirely clear, most patients with emotion and confusion often shows lack of coordination and other activities, clinical hysteria some people often mistaken for a schizophrenic. Here to tell you how to distinguish between schizophrenia and hysteria.
Difference between schizophrenia and hysteria:
Schizophrenia: even the basic personality changes, thought, emotion and behavior of the division, mental activities incompatible with the environment as the main features of schizophrenia. Cause unknown, many young adults the disease, hidden onset, mainly affecting the thinking and mental function including the perception of the real world, and thus affect the behavior and emotions. Clinical manifestations of thought, emotion and behavior disorders and mental activities, and many uncoordinated. Patients usually conscious, intelligent normal.
Hysteria: also known as hysteria, is a common mental disorder, a variety of clinical manifestations, it was called
Schizoaffective disorder is a kind of schizophrenia, patients with this type of schizophrenia and affective disorders both such as depr


ession, bipolar disorder, or mixed symptoms of mania. Characterized by significant mood symptoms (depression or mania) and schizophrenia symptoms, as schizoaffective disorder often accompanied by dysfunction, often have to be comprehensive treatment (including medication, psychological therapy and community support). Antipsychotics combined with lithium agent in the treatment of bipolar (manic) type is more effective than antipsychotics alone. Despite the effectiveness of adding antidepressants has not yet been confirmed, but in the treatment of depressive type, usually antipsychotics combined with antidepressants. new anti- psychotic drug efficacy can be better than traditional medicine.

Schizoaffective disorder known as schizoaffective disorder schizoaffective psychosis (schizo-affectivepsychosis), refers to a group of disruptive symptoms and affective symptoms exist and the same prominent mental disorders. Symptoms of delusions and hallucinations splitting thinking positive for mental disorders, symptoms, emotional symptoms of manic or depressive episode symptoms
The disease is caused by Kasanin (1933) first proposed the existence of schizophrenia patients with both mental and emotional symptoms, stress factors are induced acute onset, number of family cases have affective disorder, that is a special type of schizophrenia known as split affective, there are mixed circular said. After 1970, some scholars disease attributable to ICD-9 affective psychosis to use as a special type of so-called schizophrenia schizoaffective schizophrenia; ICD-10 will also be listed in the same category with schizophrenia in; while the United States are included in the DSM- mental disorder than other heavy
Scholars have different on its nature: atypical schizophrenia; a subtype of affective psychosis; separate disease unit is different from schizophrenia, affective psychosis also different; between schizophrenia and affective psychosis intermediate state between; is a set of different-borne diseases and some have some have schizophrenia affective disorder.
Schizoaffective disorder - Etiology
Schizoaffective disorder 1. Genetic factors of first-degree relatives of control information (Maier and Krause1989) show that the disease is between the genetics of schizophrenia and bipolar affective disorders of severe depression among the single-phase no significant The genetic specificity. Schizoaffective psychosis is speculated that both genetic disease, schizophrenia and bipolar affective disorders, but the two genes combined with the clinical features of this assumption is not consistent with a schizophrenia gene in a patient with bipolar affective psychosis also genes, the prognosis of schizoaffective psychosis to mental illness is worse than the above two, as the second disease gene from the adverse effects on prognosis. Another model is assumed to be continuity (continuitymodel), the assumption that: single-phase bipolar schizoaffective psychosis and schizophrenia is a green from yellow Blue blue-green continuous. Yellow disease, bipolar disease, schizophrenia, schizoaffective blue green psychiatric disease. This hypothesis has a lot of unresolved doubt, continue to demonstrate genotype model, the population still need to do a lot of investigation or an epidemiological investigation of relatives (SamuelG.SirisMichaelR.Lavin, 1995).
Schizoaffective proband family survey, reported that the prevalence of affective disorders is higher than the general population, more support and the relationship between affective disorder, but relatives have found a higher risk of schizophrenia support the disease variation may be schizophrenic. Some of the proband of this disease according to survey data found that family affective disorder and schizophrenia have not found high incidence of the disease schizoaffective family has increased the incidence of genetic disease that support the heterogeneity of the sex (TsuangMT, 1991).
2. Predisposing factors Kasanin the first to propose, before the onset of the disease or the great stress of life events. Brickington (1980) reported manic 10/32 split with stress before the onset of psychosis: birth surgery, head injury or significant relationship problems. Tsuang (1986) reported split before the onset of affective psychosis had more precipitating factor was 60%, while 11% of schizophrenia, manic depression, 27% to 39%. Marners et al (1990) found that schizoaffective psychosis and affective disorders life events before the onset of each 51% and 24% of schizophrenia. In addition to reports of alcohol can increase the incidence of psychotic affective syndrome risk.
3. Neuroendocrine studies in diagnostic criteria and classification of the differences on the impact of research work of this disease
Schizoaffective disorder of neuroendocrine studies have differences such as the dexamethasone suppression test (DST) in the de-inhibition type of depression in schizoaffective schizophrenia and normal low and close to the camera, unlike the high de-severe depression The same inhibition rate of the reaction of the thyroid hormone (TSH) and prolactin (Prolactin) in the injection of thyroid releasing hormone (TRH) response, the spirit of schizoaffective patients with schizophrenia and normal control response similar to, does not slow, and Patients with severe depression respond differently.
However, some of schizoaffective patients, their endocrine response and patients with endogenous depression similar to the rehabilitation of these patients schizoaffective than other mental patients more completely.
Of schizoaffective manic few studies of patients, but found at least one study, DST and TRH test results and closer to affective disorders. There is also a study, in the urine of 3 - methoxy -4- hydroxyphenyl glycol (MHPG) excretion was close to bipolar disorder rather than schizophrenia. Schizoaffective disorder - disease mechanisms
Schizoaffective disorder related to the pathogenesis of this disease, some s (SamuelSiris, MichaelLavin1995) proposed model can refer to the quality of schizophrenia. Genetic load small number of patients, irrespective of the biological basis of an extremely significant in any environment, disease can occur in schizophrenia cognitive and perceptual barriers. Genetic quality of the intermediate state are only in a series of bio-psychosocial environment - the impact of social factors in disease. Genetic quality of the load is very small person, not easily occur under the influence of the stress symptoms of schizophrenia.
Research data show that between the disease in genetics between schizophrenia and bipolar disorder. Some scholars have speculated that schizoaffective psychosis are two genetic diseases that schizophrenia and bipolar affective disorders combined two genes.
Before the onset of stress, or found a huge life events precipitating factors of this disease is 60% higher than schizophrenia, mania and depression (11 '% and 39%). In addition to reports of alcohol can increase the incidence of psychotic affective syndrome risk.
Schizoaffective disorder of neuroendocrine studies, inconsistent results. Schizoaffective disorder - clinical manifestations
Schizoaffective disorder 1. Clinical Features
(1) with typical depression or manic illness phase, but also has symptoms of both schizophrenia symptoms exist, or has a split in the pathogenesis of symptoms as delusions, hallucinations and thought disorder and other positive psychotic symptoms.
(2) recurrent disease often have intermittent symptoms of, or without leaving obvious defects.
(3) before the onset of more acute onset and may have induced stress factors.
(4) The premorbid personality of patients without obvious defects in bipolar disorder may have a family history of schizophrenia.
(5) The common age of onset in young women than men.
2. Clinical types according to the onset of affective disorder, the characteristic symptoms of affective disorders were monophasic or biphasic episodes (manic depression, or both) can be divided into 3 types: manic depressive mixed type

Schizoaffective disorder - diagnostic tests
Schizoaffective disorder mainly based on clinical features must have split the symptoms and emotional symptoms, both in the whole course of the disease exists or has occurred time and appear and disappear quite close. Attention should be paid in the diagnosis of the symptoms of the disease is not only a time evolution of the symptoms seen in the basis for the diagnosis or misdiagnosed as schizophrenia or bipolar disorder. Split the pathogenesis of clinical symptoms as the main phase of the time, must be more than 2 weeks, as a diagnosis of one of the main conditions of the disease. The disease
Diagnostic points 1. Schizophrenia and affective disorder symptoms are clinically difficult to establish priorities highlighted
2. Severely impaired social function in patients with incomplete or lack of insight
3. Disruptive symptoms and affective symptoms exist in the whole course of the disease at least 2 weeks. Time and appear and disappear quite close.
Classification system of mental illness in China (CCMD-2-R1995) will be listed in schizoaffective psychosis of schizophrenia and other psychotic disorders under the meaning of "splitting the symptoms and affective symptoms exist and equally prominent, often a recurrent disease. disruptive symptoms of delusions, hallucinations and thought disorder and other positive psychotic symptoms, affective symptoms of mania or depression. "
4. Consistent with schizophrenia and affective disorder symptoms standards.
5. Severity criteria, the following two:
(1) social function decreased significantly
(2) incomplete or lack of insight
6. Disruptive symptoms and affective symptoms and more in the whole course of the disease appear and disappear simultaneously spend more time close to but to split the main clinical symptoms of the phase of the time, must continue more than 2 weeks.
7. That if a patient were in different episodes in the performance of the disruptive symptoms or emotional symptoms as the main clinical phase based upon the relative time to onset of their main clinical diagnosis.
Type: schizoaffective psychosis, manic type; schizoaffective psychosis, depressive type; schizoaffective psychosis, mixed type.
World Health Organization diagnostic classificati0th edition (ICD-10, 1993) clinical description and diagnosis of key points in the diagnosis point is: only in the disease with the first attack in a clear and precise division of the symptoms and affective symptoms simultaneously or only a thin few days, which is inconsistent with the onset of schizophrenia do not meet the criteria for depression or manic episode only be made at this time the diagnosis of schizoaffective disorder is not the term used only in the onset of the disease, respectively, reveal different symptoms of schizophrenia and affective patients, for example, psychotic episodes in schizophrenic patients are often the aftermath of the symptoms of depression [see schizophrenia depression (F20.4)]. Some patients had repeated episodes for schizoaffective manic or depressive type can also be mixed for the other two types of patients in a typical manic or depressive episode 1 or 2 times inserted between the schizoaffective episodes, for the former case, schizoaffective episode is the appropriate diagnosis; and the latter as long as the other typical clinical phase is occasional schizoaffective episode does not overturn bipolar disorder or recurrent episodes of depression diagnosis
Schizoaffective disorder manic type of the disease in the same divisive episode manic symptoms are prominent symptoms and abnormal state of mind in the form of usually high, with increased and exaggerated idea of self-evaluation, but sometimes excitement or irritability is more apparent with the concept of aggressive behavior and victimization. In both cases there are energetic, excessive movement, concentration impairment, and loss of normal social binding. Relationship can exist, but need to exaggerate or persecutory delusions other more typical symptoms of schizophrenia can only establish the diagnosis of such patients may insist that their way of thinking is being broadcast or are disturbed alien forces are trying to control himself or tell hear a variety of different voices, or revealed the victim, not only for the content of exaggerated or bizarre delusional ideas often ask the patient to be really careful of these pathological phenomena of experience rather than a joke or a metaphor of the story. Schizoaffective disorder manic type is usually of acute onset, the symptoms clear although a wide range of behavior is often accompanied by disorder, but generally in a few weeks to complete remission. Schizoaffective disorder diagnostic criteria: there must be significant mood high, high, or less obvious state of mind associated with irritability or excitement in the same episode, there should be clear at least one, preferably two typically schizophrenic Symptoms of this type of model for a single schizoaffective manic episodes, and most of the hair as schizoaffective manic type of repeated seizures include: Schizoaffective psychosis, manic type.
Schizoaffective disorder, depressive type is the same at the onset of disease symptoms and depression in the division are prominent symptoms of mental disorders. Depressed mood is usually accompanied by several characteristic depressive symptoms or behavioral abnormalities such as retardation, insomnia, no energy, loss of appetite or weight loss, decreased interest in normal focus damage, guilt, hopelessness and suicidal ideas at the same time or in the same episode, there are other more typical schizophrenic symptoms: for example, the patient insisted that his thinking is being broadcast or is being interference or alien forces are trying to control myself. They may believe themselves to be tracked or being caught in a conspiracy, but their behavior can not be sure that they are reasonable. Can be heard not only belittle or blame for the content of the voice, but also to kill the patient, or hearing voices heard in discussions of their behavior. Schizoaffective episodes of depression-type performance is often not as good as distinct from the wild-type and amazing but generally last longer and the prognosis is poor. Although the majority of patients complete remission of individual patients with schizophrenia has gradually evolved into a defect.
Diagnosis: Depression to be significantly associated with at least 2 typical symptoms of depression or depressive episodes are related to behavioral abnormalities during an attack at the same time there is at least one kind of clear, preferably 2 typical symptoms of schizophrenia for this category simple type of schizoaffective episodes of depression, and most of the hair as repeated episodes of depressive disorder include: schizoaffective depressive type psychosis; depressive schizophrenic psychosis.
Mixed schizoaffective disorder: symptoms of schizophrenia and bipolar disorder mixed-exist by. Includes: circulation of schizophrenia.
Laboratory tests: The disease is currently no specific laboratory tests, when there complications such as infection, laboratory tests showed positive results of complications.
Other laboratory examinations: The disease is currently no specific supporting laboratory tests. Schizoaffective disorder - Differential diagnosis
Schizoaffective disorder we should exclude organic mental disorder, psychoactive substances and non-addictive substance induced mental disorders and the identification of schizophrenia or affective disorders is not difficult, the key is to identify and confirm the clinical symptoms of schizophrenia symptoms and emotional symptoms of primary and secondary status. If a patient were in different episodes in the performance of the disruptive symptoms or emotional symptoms as the main clinical phase, based upon the phase of major clinical episodes make their own diagnosis.
1. Schizophrenia, schizoaffective disorder and schizophrenia, the identification is more difficult because the symptoms of schizophrenia are often accompanied by emotions, particularly depression
(1) psychotic symptoms can continue to recover from the start before, but both share of mind course of the ratio of onset schizoaffective disorder in different psychiatric symptoms in the active period, longer duration of most of the time and the total disease onset of schizophrenia to depressive episode mood common precursor of the residual sustained period of time shorter.
(2) the severity of affective episodes schizoaffective disorder in different mood episodes state of mind in schizophrenia onset and more severe depressive episodes.
2. Identify the main point is that mood disorders, affective symptoms between the duration of psychotic symptoms can continue into the disease from the onset of the disease before the restoration, but the duration of affective symptoms was significantly different.
3. Psychotic disorder due to physical disease history, physical examination or laboratory test results indicated.
4. Substances psychotic disorder due to medication history, physical examination, especially in laboratory tests detected the drug helps patients with body fluids in the identification of the two diseases.
5. Paranoid disorder paranoid disorder paranoid psychotic symptoms only, and paranoia is not weird.
Schizoaffective disorder - Treatment
Schizoaffective disorder-like use of anti-manic drugs or combination of antidepressants and antipsychotics, can get better poor efficacy of drug treatment, such as electric shock therapy when the optional (ECT).
1. The treatment of manic schizoaffective
(1) acute phase treatment: the state of the psychotropic drugs, the most commonly used drugs are chlorpromazine and lithium salt. Both are effective in controlling acute symptoms but data suggest that control the height of excitement is better than chlorpromazine in patients with lithium salt; moderate degree of excitement in the patients than the two combined the two results have been very effective alone in the United extrapyramidal side effects increase in use with the general treatment doses of chlorpromazine dose. The dose of lithium should be adjusted by monitoring blood lithium electric shock treatment (ECT) is an acute manic effective means of emotional, when you need a quick reaction time (dangerous situation) and can be used when other treatment fails. Schizoaffective manic mania slower than the control, complete remission was not on as mania.
(2) maintenance therapy: Lithium salts can be used for maintenance therapy and prevention of split-type or bipolar manic relapse. For the maintenance treatment, the blood lithium concentration should generally be maintained at 0.60mmol / L is about to accept the long-term lithium-treated patients should pay attention to fluid and salt intake of regular testing of blood lithium levels, renal and thyroid function. In addition, lithium through the placenta and affect fetal development. The first 3 months of pregnancy to be used with caution.
(3) of the bipolar schizoaffective disorder patients and the treatment of refractory cases: In addition to antipsychotics and lithium, the anticonvulsants may be considered, such as carbamazepine (Carbamazepine, tegretol), valproate (Sod . Valproate), alone or in combination with concomitant medications should pay attention to side effects. There data suggest that combination of haloperidol and lithium salt, lithium blood levels rise, leading to significant neurological symptoms in combination with haloperidol and carbamazepine plasma concentrations of haloperidol decreased by 50%, and severe psychomotor excitement side effects of carbamazepine itself may be through metabolism, the liver enzyme system by reducing the concentration of haloperidol in blood, and sodium valproate does not affect the metabolism of drugs by the liver.
In order to control the excitement in a more rapid antipsychotic drugs, in addition to chlorpromazine, but it was suggested that clozapine is an alternative drug. Or combined with benzodiazepine drugs addition, the new antipsychotic drugs, such as risperidone olanzapine can try.
2. Schizoaffective depression treatment
(1) acute phase treatment: generally considered combined antipsychotic and antidepressant drugs on psychotic depression using an alternative solution is the traditional antipsychotics (eg phenothiazines) and antidepressants (including tricyclic and monoamine oxidase inhibitors) have experienced more validation, but when combined they are side effects (such as weight gain, etc.) was to limit their use of new antipsychotic drugs and new SSRI antidepressants may be a more attractive choice, but no system of verification. Lithium little effect on this type of but recommended course of refractory bipolar psychotic depression can have a try.
There are also the s suggest that this type of treatment with antipsychotics observed in clinical depression with psychotic symptoms disappeared in the improvement. After psychotic symptoms such as depression still exists, and eliminate the side effects of nerve blockers after antidepressant therapy can be used to gradually increase the amount of the same dosage and the treatment of primary depression, electroconvulsive therapy (ECT) may also consider in refractory Application cases (MichaelGelderDennisGath1996)
(2) maintenance therapy: the acute onset of symptoms, the need for maintenance treatment of lithium on the role of depression in schizoaffective manic type of antipsychotic drugs as to split the principle of using the same split manic type. In the maintenance treatment phase of depression episodes, such as antidepressants can be used in conjunction with the schizophrenia treatment at this time of depression, and gradually increase the dose to therapeutic dose of antidepressant medication. When symptoms disappear after schizoaffective psychotic symptoms such as persistent need to consider long-term nerve blocker (TsuangMT, 1996).
Schizoaffective disorder - Prognosis
Schizoaffective disorder abroad, splitting this disease is divided into two types of manic and depressive division. Respectively and the prognosis of schizophrenia and manic or depressive symptoms compared to Angst (1986) and Samson (1988) reof the literature information that the disease better prognosis than schizophrenia, affective psychosis worse than that of the earliest proposed schizoaffective disorder manic type of manic close to the prognosis and the prognosis of depressive and major depression was significantly different, but not for later affirmed by the data.
Coryell et al (1990) that the prognosis of this disease is a chronic indication, either split-or split manic depressive.
Longitudinal survey data to help in determining the prognosis. Data presented: continuous psychotic symptoms such as lack of emotional symptoms are indications of a poor prognosis in general literature Coryell other indications of poor prognosis: premorbid period to adapt to poor ability to adapt to poor young people, adult social adjustment is poor, and clinical course of chronic phase to long-lasting psychotic symptoms. The believes that the indications for schizoaffective and manic depressive type two (TsuangMT, 1996).
Schizoaffective disorder - Prevention
So far the spirit of universal knowledge of disease prevention and the prevention of mental illness in general is a concerted psychological, social, educational and medical aspects of the work carried out on As the current level of fundamental prevent the occurrence of mental illness and psychiatry are to be relevant development of science, as well as the etiology of various mental illnesses and pathogenesis of fully elucidated. This is given to medical science, human history, a difficult and noble mission.
In the current, almost universally accepted that the etiology of mental illness and the epidemiology of many of the issues discussed in multi-factors have to say, some of the development of mental illness and outcome of individual patient prognosis and quality of genetic susceptibility factors, premorbid personality characteristics, onset of body condition, trauma, precipitating factors in the environment as well as social and cultural background have a wide range of s before the onset of disease, stress or a huge life events precipitating factors of this disease is 60%, so for those aly events is important for preventive intervention.
First of all, should be accurate understanding of the parties to face the type of life events to understand the possible nature of social support, and their environment have some kind of reaction would then consider the need or how to intervene with the children such as marriage, separation secondary school is also the kind of thing though life events, but not necessarily pose a threat to mental health. In another example, if close relatives mourning the individual is no longer needed to help mobilize more support groups to participate in the widowed.
In contrast, the situation is in urgent need of some specific preventive interventions such as life-threatening illness for the suffering badly need major surgery where the breast such as breast cancer, so the whole resection in patients with a lack of deep sympathy and support for spouses to be given when counseling, preventive interventions (Maguire et al, 1980) is for the nurse discussed with patients before and after surgery wound repair methods described. And then followed up every 2 months 1 Check encourage exercise upper limb movement, while their spouses were informed to resume an active mobilization of the work. The project was conducted in 152 women were randomly divided into experimental and control the two groups and then 3 months after surgery 12 months and 18 months of analysis and evaluation of anxiety and depression and sexual problems happened. Assessment results indicate that both groups produce anxiety, depression and sexual problems, but the experimental group continued up to 6 months in the control group during the first 10 months the experimental group also asked to eliminate all social functions to resume work fine. Absence of the breast can be adapted for wearing fake breasts are also very satisfied.
In order to stimulate a sense of psychological stress and preventive intervention to prevent psychological abnormality spontaneously in society, some countries set a plethora of support groups for social solidarity movement. For instance, young people aged 12 to 20 families living in alcoholism support groups, promising those mourning the establishment of "Friends of sympathy" group, set up mutual aid organizations for the blind, to parents of disabled children to set up mutual aid and mutual aid organizations, etc. As members and thus subject to similar but yet the same boat accumulated many valuable experiences and desirable approach is not the end despite the prevention of mental disorders, but at least exchange information, emotional support actions can be of help. This can in effect play a role to cope with difficult situations, and thus has broad significance of mental health.
Stimulating life events impact on the individual state of profound mental problems than bereavement. Bereavement grief reaction was a reaction, when the transit is still some people after prolonged shift in the evolution of emotional depression and some form of depression. Many experts have studied the psychological abnormality of mourning prediction, and high risk long-term follow-up arrangements to be confirmed. Parkes (1981) who proposed mourning easy to produce abnormal psychology major risk factors: has been attached to the deceased, irritability or good self-blame, the deceased's death was not prepared for the lack of the necessary family support , living The low level of economic and cultural. Parkes high-risk groups for intervention and a control group and experimental group after 20 months did not produce symptoms of anxiety and autonomic drugs and alcohol and tobacco consumption is also lower than the control group.
The disease should be treated as the acute phase of schizophrenia antipsychotic rapidly select effective control of psychotic symptoms so that patients fully recovered, including the restoration of insight. Maintenance treatment, as the recovery situation. Such as the resumption of long-term maintenance therapy do not completely once found signs of recurrence antipsychotic treatment should be given time
Schizoaffective disorder - Related Content
Diagnosis of schizoaffective disorder due to classification differences and changes difficult to obtain precise epidemiological data are not uncommon, but clinically the World Health Organization (1975), 10 countries reported 811 cases of schizophrenia, schizoaffective psychosis 107 13% to Shanghai, Suzhou 301 patients hospitalized between schizophrenia survey (1977), the disease accounts for 5.3% of 16 patients there is a survey of foreign schizoaffective psychosis that the annual incidence rate was 0.3 million rather 5.7/10 in the annual incidence of schizophrenia ~ 15.0/10 7.3 million to 1 / 4 is roughly equivalent to the annual incidence of mania 1.7 ~ 3.3/10 million. Lifetime prevalence rate of 0.5% ~ 0.8% (TsuangMT1996) with age of onset of schizophrenia, mostly in adolescence or adulthood disease not found in gender, race, region, or the special ties between social classes.
Assuming domestic and foreign scholars have different on the causes: variation of the disease is schizophrenia, the disease is affective disorder is a variant of atypical schizophrenia ; is a subtype of affective psychosis; disease as an independent unit unlike schizophrenia or affective psychosis; and affective psychosis between the intermediate state between; heterogeneity is a group of diseases, some considered to be a subtype of schizophrenia, some that is a subtype of affective disorder; schizophrenia and affective disorders quality of interaction between the quality of the product (SamuelG.SirisMichaelR.Lavin1995) Hafner et al (1990) that the demographic data from the gender distribution of age of onset and prevalence of symptoms school, course and prognosis and treatment response variables such as the suicide rate are supported between schizoaffective psychosis is between the two cases of functional psychosis (caseinbetween) (HafnerH1990).
Shanghai and other units (1978) reported 70 patients with schizoaffective psychosis clinical data: acute and subacute onset accounted for 89.8% of patients the first 2 / 3 of the incentive, premorbid personality characteristics between high-and accounted for 78.6%. Control, Nanjing Neuropsychiatric Hospital (1978) 20 cases of 64 people of mixed psychiatric clinical analysis: acute and subacute onset accounted for 56.2%, prior to the onset accounted for 83.6% of the incentive. Female: Male 4:1, 1st female patients the average age of onset of 23.5 years; male patients 30.2 years old compared with a genetic predisposition of the disease was a family history of mental illness accounted for 50% (Nanjing) and 57.1% (Shanghai), higher than the Clinical features of schizophrenia and bipolar disorder divisive and emotional visible symptoms simultaneously or alternately repeatedly attack the symptoms of schizophrenia can be emotional or confusion associated with the shortest half of the first episode, the longest 4.5 to 5 years . Interval of 1 month to 4 to 6 years. Generally believed that the better prognosis of the disease. Shanghai Institute of Prevention and 67 patients an average of 7.5 years of follow-up information: relief well, 20.9%, 59.8% were still good at the onset of the disease were 17.8% passive, suicide deaths by 1.5%.
