Question 1

Which of the following is not one of the DSM-IV subtypes of schizophrenia?

Accepted Answer

Histrionic schizophrenia is not one of the DSM-IV subtypes of schizophrenia. The actual subtypes listed in DSM-IV are paranoid schizophrenia, disorganized schizophrenia, catatonic schizophrenia, undifferentiated schizophrenia, and residual schizophrenia.

Question 2

All of the following brain abnormalities have been associated with schizophrenia in some patients, except

Accepted Answer

While abnormalities have been found in the frontal lobes, hippocampus and amygdala, and the lateralization of brain hemispheres in some patients with schizophrenia, there is no evidence of abnormal functioning of the brainstem specifically being associated with the disorder.

Question 3

Which of the following people probably would have had a diagnosis of paranoid schizophrenia?

Accepted Answer

Walter's belief that the Russians are trying to kidnap him because he is so important is a delusion, which is a symptom commonly associated with paranoid schizophrenia. The other options do not provide enough information to make a diagnosis.

Question 4

Which statement is true about the risk of developing schizophrenia for a person adopted at birth?

Accepted Answer

The risk of developing schizophrenia is greater if the biological parents have schizophrenia. This suggests that genetics plays a role in the development of schizophrenia. Having adoptive parents with schizophrenia does not appear to increase the risk.

Question 5

Maurice suffers from a schizophrenia characterized by silliness and incoherence. He has strange facial expressions and mannerisms, and his behaviour is quite bizarre. Maurice most likely suffers from which historical type of schizophrenia?

Accepted Answer

Maurice's symptoms of silliness, incoherence, bizarre behaviour, and strange facial expressions and mannerisms are characteristic of disorganized schizophrenia, which used to be called hebephrenic schizophrenia.

Question 6

All of the following brain abnormalities have been associated with schizophrenia in some patients, except

Accepted Answer

Random neural firing in the occipital lobe has not been consistently associated with schizophrenia. The other three options have been found in some patients with schizophrenia.

Question 7

Maurice is convinced that he is Jesus Christ. Such a belief would best fit which historical type of schizophrenia?

Accepted Answer

Maurice's belief that he is Jesus Christ is a delusion of grandeur, which is most commonly associated with paranoid schizophrenia. Disorganized schizophrenia is characterized by disorganized speech and behavior, catatonic schizophrenia involves unusual movements or postures, and residual schizophrenia is a subtype in which individuals have a history of schizophrenia but are currently only experiencing mild symptoms.

Question 8

One form of treatment for schizophrenia involves

Accepted Answer

Blocking dopamine action is a commonly used form of treatment for schizophrenia, as high levels of dopamine in certain areas of the brain are associated with the disorder. This is typically done through the use of antipsychotic medications that work by blocking the dopamine receptors in the brain. Elevating serotonin levels and increasing GABA output have not been shown to effectively treat schizophrenia, and hydrotherapy is not a recognized treatment for the disorder.

Question 9

Which of the following persons probably would have had a diagnosis of catatonic schizophrenia?

Accepted Answer

Louise's behavior of standing for hours in the same strange position is characteristic of catatonic schizophrenia, which involves unusual movements and postures.

Question 10

There is substantial research evidence for all of the following having roles as causes of schizophrenia, except

Accepted Answer

While there is research evidence to support the role of stress in those predisposed to schizophrenia, unhealthy family interaction patterns, excessive dopamine activity, and genetic factors in the development of schizophrenia, there is not substantial evidence to support unhealthy family interaction patterns as a direct cause of the disorder.

Question 11

Which of the following people would have had a diagnosis of disorganized schizophrenia?

Accepted Answer

Valentina's symptoms of making silly faces, laughing a lot, masturbating openly, and eating strange things indicate disorganized behavior and are characteristic of disorganized schizophrenia.

Question 12

Which of the following people probably would have had a diagnosis of undifferentiated schizophrenia?

Accepted Answer

Undifferentiated schizophrenia is a type of schizophrenia where the symptoms fit no particular subtype. Matthias, who has symptoms of schizophrenia but doesn't fit any one type, is the best candidate for undifferentiated schizophrenia. Valentina's symptoms suggest disorganized schizophrenia, Walter's symptoms suggest paranoid schizophrenia, and Louise's symptoms suggest catatonic schizophrenia.

Question 13

Which of the following is not one of the major symptoms of schizophrenia?

Accepted Answer

Split personality is not a symptom of schizophrenia. Schizophrenia is a mental disorder characterized by a range of symptoms, such as delusional thinking, hallucinations, and inappropriate affect. However, split personality refers to dissociative identity disorder, which is a distinct disorder characterized by the presence of two or more distinct personality states.

Question 14

Walter is extremely agitated because he believes his neighbours are spying on him, spreading rumours about him, and following him wherever he goes. Using the DSM-IV-TR, Walter would have most likely received a diagnosis of

Accepted Answer

Walter's belief that his neighbours are spying on him, spreading rumours, and following him is characteristic of paranoid schizophrenia, which is characterized by delusions and hallucinations, specifically of a persecutory nature.

Question 15

Patients suffering from which historical type of schizophrenia have the poorest chance of recovery and the most severe and bizarre symptoms?

Accepted Answer

Disorganized schizophrenia is characterized by incoherent speech, disorganized behavior, and emotional flatness. These patients have the poorest chance of recovery and the most severe and bizarre symptoms compared to other types of schizophrenia.

Question 16

In which historical type of schizophrenia does an individual maintain a rigid, unusual posture for a long period of time and then suddenly erupt into activity?

Accepted Answer

The description of maintaining a rigid, unusual posture for a long period of time followed by sudden activity is characteristic of catatonic schizophrenia. In this type of schizophrenia, individuals have disturbances in movement, including immobility, excessive activity, and unusual postures or mannerisms. These symptoms can be so severe that the person appears to be in a stupor or trance-like state.

Question 17

Zelda suffers from schizophrenia. Her primary symptom is experiencing delusions of persecution. This type of schizophrenia was called

Accepted Answer

Delusions of persecution are a primary symptom of paranoid schizophrenia. Undifferentiated schizophrenia involves a lack of clearly defined symptoms, catatonic schizophrenia involves disruptions in movement and behavior, and disorganized schizophrenia involves disorganized thinking and speech.

Question 18

Which of the following has not been found in relation to the genetic factors in schizophrenia?

Accepted Answer

While genetic factors play a role in the development of schizophrenia, it is not true that if one identical twin develops schizophrenia, the other twin will eventually develop it. Research shows that the likelihood of the other twin developing the disorder is about 50%.

Question 19

One significant contributing factor to schizophrenia appears to be that people who suffer from schizophrenia are particularly

Accepted Answer

Research suggests that stress is a major contributing factor to the development of schizophrenia, and people with schizophrenia appear to be more vulnerable to stress than the general population.

Question 20

Sanjaithna sits for long periods with her arms outstretched, looking like a statue. At other times, she is extremely agitated and excitable. Historically, Sanjaithna's diagnosis would have been

Accepted Answer

Sanjaithna displays symptoms of both catatonic behavior (sitting for long periods with arms outstretched) and excitement (agitation and excitability), which are characteristic of catatonic schizophrenia.
