Diagnostic Features This disorder, at some point in the illness, involves a psychotic phase (with delusions, hallucinations, or grossly bizarre/disorganized speech and behavior). This psychotic phase must last for at least one month (or less if successfully treated). Schizophrenia also causes impairment in social or vocational functioning which must last for at least 6 months. The psychotic phase is not due to a medical condition, medication, or illegal drug. Complications Individuals with this disorder may develop significant loss of interest or pleasure. Likewise, some may develop mood abnormalities (e.g., inappropriate smiling, laughing, or silly facial expressions; depression, anxiety or anger). Often there is day-night reversal (i.e., staying up late at night and then sleeping late into the day). The individual may show a lack of interest in eating or may refuse food as a consequence of delusional beliefs. Often movement is abnormal (e.g., pacing, rocking, or apathetic immobility). Frequently there are significant cognitive impairments (e.g., poor concentratiion, poor memory, and impaired problem-solving ability). The majority of individuals with Schizophrenia are unaware that they have a psychotic illness. This poor insight is neurologically caused by illness, rather than simply being a coping behavior. This is comparable to the lack of awareness of neurological deficits seen in stroke. This poor insight predisposes the individual to noncompliance with treatment and has been found to be predictive of higher relapse rates, increased number of involuntary hospitalizations, poorer functioning, and a poorer course of illness. Depersonalization, derealization, and somatic concerns may occur and sometimes reach delusional proportions. Motor abnormalities (e.g., grimacing, posturing, odd mannerisms, ritualistic or stereotyped behavior) are sometimes present. The life expectancy of individual with Schizophrenia is shorter than that of the general population for a variety of reasons. Suicide is an important factor, because approximately 10% of individuals with Schizophrenia commit suicide - and between 20% and 40% make at least one suicide attempt. There is an increased risk of assaultive and violent behavior. The major predictors of violent behavior are male gender, younger age, past history of violence, noncompliance with antipsychotic medication, and excessive substance use. However, it should be noted that most individuals with Schizophrenia are not more dangerous to others than those in the general population. Comorbidity Alcoholism and drug abuse worsen the course of this illness, and are frequently associated with it. From 80% to 90% of individuals with Schizophrenia are regular cigarette smokers. Anxiety and phobias are common in Schizophrenia, and there is an increased risk of Obsessive-Compulsive Disorder and Panic Disorder. Schizotypal, Schizoid, or Paranoid Personality Disorder may sometimes precede the onset of Schizophrenia. Diagnostic Tests No laboratory test has been found to be diagnostic of this disorder. However, individuals with Schizophrenia often have a number of (non-diagnostic) neurological abnormalities. They have enlargement of the lateral ventricles, decreased brain tissue, decreased volume of the temporal lobe and thalamus, a large cavum septum pellucidi, and hypofrontality (decreased blood flow and metabolic functioning of the frontal lobes). They also have a number of cognitive deficits on psychological testing (e.g., poor attention, poor memory, difficulty in changing response set, impairment in sensory gating, abnormal smooth pursuit and saccadic eye movements, slowed reaction time, alterations in brain laterality, and abnormalities in evoked potential electrocephalograms).Prevalence Schizophrenia is the fourth leading cause of disability in the developed world (for ages 15-44), and Schizophrenia is observed worldwide. Lifetime prevalence varies from 0.5% to 1.5%. The incidence of Schizophrenia is slightly higher in men than women. Negative symptoms (e.g., social withdrawal, lack of motivation, flat emotions) tend to predominate in men; whereas depressive episodes, paranoid delusions, and hallucinations tend to predominate in Course Schizophrenia usually starts between the late teens and the mid-30s, whereas onset prior to adolescence is rare (although cases with age at onset of 5 or 6 years have been reported). Schizophrenia can also begin later in life (e.g., after age 45 years), but this is uncommon. Usually the onset of Schizophrenia occurs a few years earlier in men than women. The onset may be abrupt or insidious. Usually Schizophrenia starts gradually with a prepsychotic phase of increasing negative symptoms (e.g., social withdrawal, deterioration in hygiene and grooming, unusual behavior, outbursts of anger, and loss of interest in school or work). A few months or years later, a psychotic phase develops (with delusions, hallucinations, or grossly bizarre/disorganized speech and behavior). Individuals who have an onset of Schizophrenia later in their 20's or 30's are more often female, have less evidence of structural brain abnormalities or cognitive impairment, and display a better outcome. Schizophrenia usually persists, continuously or episodically, for a life-time. Complete remission (i.e., a return to full premorbid functioning) is uncommon. Some individuals appear to have a relatively stable course, whereas others show a progressive worsening associated with severe disability. The psychotic symptoms usually respond to treatment with antipsychotic medication, whereas the negative symptoms are less responsive to antipsychotic medication. Often the negative symptoms steadily become more prominent during the course of Schizophrenia. Outcome The best outcomes are associated with early and persistent treatment with antipsychotic medication soon after the onset of Schizophrenia. Other factors that are associated with a better prognosis include good premorbid adjustment, acute onset, later age at onset, good insight, being female, precipitating events, associated mood disturbance, brief duration of psychotic symptoms, good interepisode functioning, minimal residual symptoms, absence of structural brain abnormalities, normal neurological functioning, a family history of Mood Disorder, and no family history of Schizophrenia. Familial Pattern The first-degree biological relatives of individuals with Schizophrenia have a risk for Schizophrenia that is about 10 times greater than that of the general population. Concordance rates for Schizophrenia are higher in monozygotic (identical) twins than in dizygotic (fraternal) twins. The existence of a substantial discordance rate in monozygotic twins also indicates the importance of environmental factors. Treatment Antipsychotic medication shortens the duration of psychosis in Schizophrenia, and prevents recurrences (but psychotic relapses can still occur under stress). Usually it takes years before individuals can accept that they have Schizophrenia and need medication. When individuals stop their antipsychotic medication, it may take months (or even years) before they suffer a psychotic relapse. Most, however, relapse within weeks. After each psychotic relapse there is increased intellectual impairment. Antipsychotic medication (+/- antidepressant medication +/- antianxiety medication) usually prevents suicide, minimizes rehospitalization, and dramatically improves social functioning. Unfortunately, even on antipsychotic medication, most individuals with Schizophrenia can't return to gainful employment due to the intellectual impairments caused by this illness (e.g., poor concentration, poor memory, impaired problem-solving, inability to "multi-task", and apathy). Life-long treatment with antipsychotic medication is essential for recovery from Schizophrenia. Individuals also require long-term emotional and financial support from their families. Most individuals with Schizophrenia qualify for government (or insurance) disability pensions. Social rehabilitation (e.g., club-houses, supervised social activities) and sheltered/volunteer employment are also essential. Certain illicit drugs, especially cannabis ("pot") , have been shown to actually cause Schizophrenia.

What mental health professional is the best recommendation for a friend who confides to you that she fears she might have schizophrenia?

User Avatar

Asked by Wiki User

Her best bet is a psychiatrist. Schizophrenia is best treated with both psychotherapy (also called "talk" therapy) and medicine. Psychiatrists can both prescribe medicine and provide psychotherapy. Even if it turns out that she doesn't have schizophrenia, the psychiatrist can help her understand why she thought that she did (or, if she has a related disorder, help her with that) and refer her to another specialist if she should see one. Tell her that if she tells her doctor that she wants to see a psychiatrist then her doctor will recommend one who is covered by her health care plan.

Can you have some type of psychosis without hallucinating?

Yes. 75 percent of people with schizophrenia hallucinate; however, that means that 25 percent- one out of four- do not hallucinate. Hallucinations are not necessary for the diagnosis of schizophrenia.

Does schizophrenia get worse as you age?

Asked by Wiki User

That is completely dependent on how each child responds to attempts at pulling them out of some of their behaviors, stims, etc. There are many therapies available, ABA, OT, Speech therapy, RDI, SonRise, etc etc A lot of parents try bio-medical and dietary approaches toward a better quality of life for their children with autism. Some children respond amazingly well and DO get better with age, while other stay the same or get more frustrated as the years pass.

Can someone fake being schizophrenic?

User Avatar

Asked by Wiki User

It would be possible, but very difficult. You would have to be an expert in schizophrenia in order to fake all of the symptoms and fool the psychiatrists. You would also have to keep up the pretence for a long time. There would be a lot more chances for you to trip and act normal than there would for you to fake it.

However, it is possible. People fake mental illness a lot of the time (Munchausen's Syndrome, though this is more commonly physical illness). However, why you would want to is beyond me as it will most likely involve you being "voluntarily" admitted to a psychiatric ward or community care team or being sectioned under the Mental Health Act, giving the ability for doctors to forcibly give you depot injections of antipsychotic medication.

In fact, there was an experiment done by the psychologist David Rosenhan that showed that people could fake schizophrenia (I'm not sure if it was paranoid schizophrenia or not) well enough to get into a mental hospital. A group of subjects agreed to go to a mental hospital and say that they had auditory hallucinations (hearing voices). They were, in fact, perfectly normal. Many of them were locked up for weeks or even months before they decided to stop.

Can schizophrenia be caused by smoking?

User Avatar

Asked by Wiki User

Smoking does not reduce the causes of schizophrenia. However, there is some indication that smoking can reduce either the symptoms of schizophrenia or the side effects of antipsychotic medications, or both, which may be why 70-90 percent of people with schizophrenia smoke. The semi-beneficial effects of nicotine on people with schizophrenia may be caused by increased levels of acetycholine, which increases mood, and glutamate, which improves memory, in the brain. Both mood and memory problems are prevalent among people with schizophrenia.

Is there such a thing as a mild form of schizophrenia?

User Avatar

Asked by Wiki User

Opinions are divided on that. Some clinicians say that mild cases of schizophrenia are possible, and are in fact true in cases of paranoid, schizoid, and schizotypal personality disorders. Others say that schizophrenia is schizophrenia, and you cannot have a milder form of it.

Does schizophrenia mean split personalities?

User Avatar

Asked by Beatlemania1234

Persons with schizophrenia do not have "split personality". Their illness is due to biochemical disturbance of the brain. The symptoms are as follows:

- disconnected and confusing language

- poor reasoning, memory and judgment

- high level of anxiety

- eating and sleeping disorders

- hallucinations or hearing and seeing things that only exist in the mind of the consumer

- delusions or persistent false beliefs about something (i.e. that others are controlling their thoughts)

- deterioration of appearance and personal hygiene -tendency to withdraw from others

Paranoid schizophrenia is a mental health disorder in which the person believes that he or she is being persecuted when he or she is not, shows a pervasive (continuing) pattern of this, and has those beliefs when most people would say that there is no reason to believe that the person is being persecuted. If John believed that people at work were trying to hurt him and were always talking behind his back, then that would be an indication that John had paranoid schizophrenia.

Paranoid adolescent schizophrenia would be paranoid schizophrenia in teenagers, not in adults.

Are hallucinations a negative symptom of schizophrenia?

User Avatar

Asked by Wiki User

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).

Is Thorazine most likely to provide schizophrenia patients with some relief from their auditory hallucinations and paranoia?

User Avatar

Asked by Wiki User

Neuroleptics, or antipsychotics, are the drugs most commonly used to treat schizophrenia. They block the dopamine pathways to reduce the amount of dopamine in the brain, which could be one cause of the schizophrenia. However, it's difficult to get patients to stay on their medication because of the unpleasant side effects.

Can temporal lobe epilepsy be mistaken for schizophrenia?

A properly qualified doctor would not misdiagnose in that manner. Medically they are very different conditions, though they can have some similar symptoms. This is why some people can confuse the two.

What is the Definition of schizophrenic?

User Avatar

Asked by Wiki User

The term 'schizophrenic' refers to someone with schizophrenia, a severe thought disorder usually characterized by hallucinations (false sensations, like seeing or hearing things that aren't really there), delusions (false beliefs), disordered thinking, flat affect (no emotional reactions to stimuli), disordered or strange speech patterns and very disorganized/abnormal behavior. These symptoms have to have a severely disruptive effect on the person's home/work/social life to be truly considered schizophrenia. There are several types of schizophrenia, including paranoid schizophrenia (where the hallucinations/delusions are linked to a paranoid fear), catatonic schizophrenia (includes incidences of catatonic [motionless] stupors and extreme flexibility), hebephrenic schizophrenia (largely disordered thought and flat affect) and undifferentiated schizophrenia (symptoms don't fall into one of the other three types).
A schizophrenic is a person that suffers from schizophrenia. Schizophrenia is a thought disorder, where there is a disturbance in thought patterns and processes. People with schizophrenia usually have several of the following symptoms:

- disconnected and confusing language

- poor reasoning, memory and judgment

- high level anxiety

- eating and sleeping disorders

- hallucinations or hearing and seeing things that only exist in the mind of the consumer

- delusions or persistent false beliefs about something (i.e. that others are controlling their thoughts)

- deterioration of appearance and personal hygiene -tendency to withdraw from others

Do people see things when they have Schizophrenia?

Asked by Wiki User

Yes they do. They can see and hear things. Their perception can be completely different. They can have full relationships with people that don't even exist. My sister has this and it's very hard at times but with the right medications and therapy, you can live a normal life.

What is the difference between bipolar and schizophrenia?

Asked by Wiki User

no such thing with that name, but there is schizoaffective disorder, somewhere between the two.

There may be two different disorders that exhibit characteristics of bipolar and schizophrenia.

The previous answer named one, Schizoaffective disorder, bipolar type. Persons with this disorder will experience psychotic symptoms (delusions, hallucinations, paranoia, etc) even if they are not in a mood episode. But they will also experience symptoms of a manic or depressed mood episode.

There are also many types of Bipolar disorder, and some people will experience the psychotic symptoms listed above, but only if they are experiencing a mood episode (manic, depressed, mixed). If the person with this disorder is not in a mood episode, they will not experience the psychotic symptoms.

What is residual schizophrenia?

Asked by Maniesansdelire

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).
