Psychotic Disorders

Source of answers, unless otherwise noted are DSM-IV-TR or APA Practice Guideline on schizophrenia, Supplement to AJP, February,

2004.As of 10July2012

2

Dx criteria

Q. What are the dx criteria for schizophrenia?

3

Dx criteria

Ans. Two or more of five:

1] delusions

2] hallucinations

3] disorganized speech

4] disorganized behavior or catatonia

5] deficit signs of flat affect, apathy, alogia, and so on [“negative” signs].

4

Delusions - exception

Q. Under what circumstances can you give a person a dx of schizophrenia when delusions is the only one of the five supra that the pt has?

5

Delusions -exception

Ans. When the delusions are “bizarre.” By bizarre, DSM means that the idea could not be true. It could be true, for example, that someone is poisoned, but it could not be true that the pt’s father lives on the planet Jupiter. [Thus, one does not need to dx psychotic disorder NOS when faced with a six month illness that only has bizarre delusions, but can dx “schizophrenia.”]

6

Hallucinations - exception

Q. What characteristics of hallucination allows one to dx a person with schizophrenia even when the individual lacks any of the other four signs of schizophrenia listed supra?

7

Hallucinations -- exceptions

Ans. Two exceptions:

1] “Hearing” a voice constantly reflecting on the pt’s behavior or thoughts.

2] “Hearing two voices conversing with each other.

8

Catatonia v. paranoid

Q. Your pt has the signs of catatonic type and has the signs of the paranoid type, what is the dx?

9

Catatonic v. paranoid

Ans. Catatonic Type. The catatonic type trumps all the other types. Disorganized type also trumps paranoid type.

10

Deficit signs

• Q. Your pt has developed deficit [negative] signs. Besides being part of schizophrenia, what are two other possibilities common in psychiatric practice?

[These slides avoid the terms “positive” and “negative” and instead use “psychotic” and “deficit.”]

11

Deficit signs

Ans. While the list could be long, two will probably reach the exam question:

• -- Parkinsonian signs from the meds.

• -- Depression

12

Schizoaffective Disorder

• Q. Criteria for schizoaffective disorder?

13

Schizoaffective Disorder

Ans. Someone who has:

• -- signs of a mood disorder

• AND

• -- delusions or hallucinations for at least two weeks when mood disorder is not present. [note, not “schizophrenia,” but “delusions or hallucinations.”]

14

Structural Neuroimaging studies

Q. Most consistent structural neuro-imaging finding of these pts with schizophrenia in comparison to general population?

15

Structural Neuroimaging studies

Ans. Enlargement of lateral ventricles.

16

Functional neuroimaging studies

Q. What has been the most consistent finding as to functional neuroimaging studies in pts with schizophrenia?

17

Functional neuroimaging studies

Ans. Hypofrontality.

18

Schizophrenia - death

• Q. People with schizophrenia death rate compared with the general population is?

19

Schizophrenia - death

Ans. Die a decade or more earlier. [since 2007, “25 years” has become a common figure.]

20

Death rate - why

Q. List the three reasons why the death rate is higher.

21

Death rate - why

• Suicide rate is much higher

• Accidents are much more common

• Medical care is more inadequate.

• [Side effects of meds that are used to treat the mentally ill may become the fourth.]

22

Suicide

Q. What is rate of suicides?

23

Suicides

Ans. DSM-IV says 10%. More recent studies say 5%.

24

Suicide risks

• Q. What five suicide risk factors DIFFER from the suicide risk factors of the general populations? That is, if you are doing a risk assessment on a pt with schizophrenia, what findings would increase the suicide risk chances with pt with schizophrenia, findings that would not increase the suicide risk in the general population.

25

Suicide – risk factors

Ans. Risk factors that are different from the general population include:

• 1. Young• 2. High socioeconomic status• 3. High IQ• 4. Good scholastic record• 5. High aspirations• [This is a pretty common question on Boards,

consistent with the focus on passing a safe psychiatrist.]

26

Proven to reduce suicide in people with schizophrenia

• Q. Med/meds proven to reduce suicide rate?

27

Proven to reduce suicide rate

Ans. Clozapine

• [Lithium’s use might be an acceptable answer too, but clozapine has a specific FDA approval for suicidal risk in pts with schizophrenia. Li does not.]

28

Suicide - prediction

• Q. Status of clinicians ability to predict suicide?

29

Suicide - prediction

Ans. Not able to predict.

[This will be correct answer to almost any question as to ability to predict suicide, not just the psychotic disorders.]

30

Aggressive behavior

• Q. List three co-morbid disorders that increase risk of aggressive behavior in pts with schizophrenia.

31

Aggressive behavior

Ans.

• 1. Substance abuse/dependence [especially PCP, but alcohol, cocaine, and sedatives]

• 2. Neurological disorders

• 3. Antisocial personality

32

Prognosis – family hx

• Q. Does a hx of mood disorders in the family hx suggest a poorer prognosis for your pt with schizophrenia?

33

Prognosis – family hx

Ans. A family hx that has a mood disorder has a better prognosis.

34

Prognosis - gender

• Q. Does gender make a difference as to prognosis?

35

Gender

Ans. Women have a better prognosis.

36

Prognosis – age of onset

• Q. What about prognosis and age of onset?

37

Prognosis - age

Ans. The later the onset of the illness, the better the prognosis.

38

Prognosis – Mental Status

• Q. What two mental status findings have a good prognosis?

39

Prognosis – mental status

• A. Good prognostic signs are:

• -- Lack of anosognosia

• -- Signs of mood disorder

[If neither of the above two are among the choices, seems confused may be the correct answer.]

40

Prognosis – Course of illness

• Q. What course of illness suggests a good prognosis?

List two as to onset.

List one as inter-episode functioning.

41

Prognosis - course

Ans. The following suggest a relatively good prognosis:

• -- acute onset

• -- precipitating, traumatic, event

• -- good prior-episode or good inter-episode functioning

42

Stages

• Q. APA Practice Guideline has what stages for schizophrenia?

43

Schizophrenia - stages

• Ans.

• -- Acute

• -- Stabilization

• -- Stable [“maintenance” also used]

44

Acute phase

• Q. Definition of acute phase?

45

Acute phase

Ans. Beginning with the onset of the episode until the pt reaches what the clinician believes is to be the pt’s baseline.

46

Course

• Q. You are treating a pt during his first break, age 21. What are the chances he will never have another schizophrenic episode?

47

Course

Ans. 10-20%

48

Maintenance

• Q. Indefinite maintenance of antipsychotic meds is recommended when?

49

Maintenance

• Ans. If the pt has had two psychotic episodes within five years.

50

51

Stable phase - relapse

Ans.

• 1/3 with meds within one year

• 2/3 without meds within one year

52

Predicting who doesn’t need meds

• Q. Is there a very reliable way to predict which of your pts with schizophrenia will never need meds again after stable stage is reached?

53

Predicting who will not need meds

• Ans. No reliable way to identify this minority.

54

Poor prognosis

• Q. What factors suggest a poor prognosis as to treatment response? Use the following outline.

GenderPre-natal factorsPeri-natal factorsPre-morbid functioningSeverity of signs of delusion and hallucinationsDuration of untreated psychosisEPS side effectsFamily setting

55

Poor prognosis - 1

• Ans. Any of the following ten factors decreases the chances of a good prognosis:

• 1. male

56

Poor prognosis - 2

• 5. Severe delusions

• 6. Attentional impairment

• 7. Poor premorbid functioning

Schizophrenia – treatmentdeficit signs

• Q. Proven treatment in controlled studies for deficit [“negative”] signs?

58

Treatment – deficit signs

• Ans. None proven for deficit [negative] signs. When pt does dramatically improve as to deficit signs, may be a function of the switch of meds as to less side effects, not an improvement in the schizophrenia per se.

59

Treatment - psychosocial

60

Treatment - psychosocial

Ans. • -- supportive psychotherapy• -- CBT• -- group therapy• -- family therapy• -- social skills training• -- supportive employment• -- ACT/PACT

• ACT = Assertive Community Treatment

• PACT = Program for Assertive Community Treatment.

• Above is community based, 7x24, in which the team goes to where each pt is, there home, their bar, whatever.

65

ACT/PACT

• Q. For what pts is ACT/PACT indicated?

66

ACT/PACT

• Ans. two conditions:

• 1] Pt has high risk of hospital readmission.

• AND

• 2] Unable to use usual community-based [e.g., clinic] resources.

67

68

Treatment - benzodiazepines

• Ans. Signs of:

• -- Agitation

• -- Anxiety

• -- Catatonia

69

Treatment - benzodiazepines

• Q. Role of benzodiazepines in management of stable phase?

70

Schizophrenia - benzodiazepines

• Ans. In stable phase:

• -- Insomnia

• [while not in Guideline, one can probably assume that if lorazepam was a major success in abolishing catatonia in acute phase, it would be continued.]

71

72

Schizophrenia – beta-blockers

• 2. Clozapine failures that have:a. persistent, severe psychosis

b. suicidal

77

Relapse

Q. List four causes of relapse in schizophrenia?

78

Relapse

Ans. Causes include:

• 1. non-compliant with treatment

• 2. stressful event

• 3. use of substance or alcohol

• 4. natural course of illness

79

Substance Abuse• Q. Excluding smoking, what percentage of

people with schizophrenia have a substance-related disorder?

80

Substance abuse

• Ans. 50%

81

Dual dxed pts

• Q. Best psychiatric management of pt with schizophrenia and a substance dependence?

82

Dual dxed pt

• Ans. Integrated, comprehensive and carried out by the same team.

[This is politically correct answer for all dual dx pts, not just those with schizophrenia.]

83

Treatment of first episode - meds

• Q. What meds are indicated for the first episode?

84

Treatment of first episode - meds

Ans. All atypicals except clozapine.

[This answer is pre-CATIE. Would be hard to justify this post-CATIE if someone preferred perphenazine.]

85

Medication effects on second episode

• Q. How do medications during the first episode differ from latter episodes as to impact on the pt? For example, your pt had good response to risperidone on 1 mg BID during first episode with side effects of dizziness and dry mouth in his first hospitalization. He failed to take meds after your hospital discharge and was readmitted with another episode of schizophrenia. What would you expect if you use risperidone again?

86

Medications impact on first episode

Ans. Pt is less sensitive as to the therapeutic effects AND less sensitive as to the side effects. You will probably need to use higher dose that 1 mg BID for the second hospitalization and the side effects might be less prominent.

87

Clozapine as initial medication

Q. How does clozapine compare with other antipsychotics for naïve-medication patient? Will it perform better, for example, than chlorpromazine?

88

Clozapine as initial medication

Ans. Will not do better. So, in addition to the usual side effect concerns, there is no evidence that clozapine is superior in pts in their first acute episode. Clozapine might be the correct answer in highly suicidal pt.

89

Hx of weight gain, hyperglycemia, or hyperlipidemia

• Q. With the hx of weight gain, hyperglycemia or hyperlipidemia with prior antipsychotics, what meds would now likely become first choice if they have not already been used and found wanting?

90

Hx of weight gain, hyperglycemia or hyperlipidemia

• Ans. aripiprazole or ziprasidone.

91

Weight gain

• Q. Weight gain is hypothesized to be associated with which two receptor site?

92

Weight gain

Ans. Meds blocking

• H1

• OR

• 5-HT2C

93

Weight gain & med discontinuance

• Q. When one discontinues an antipsychotic that apparently was related to gaining weight, what is the impact of discontinuance of that medication on the pt’s weight? Rapidly return to pre-med weight?

94

Weight gain & med discontinuance

Ans. Usually, no further weight gain, but what has been gained will not be automatically loss. If pt has gained 25 pounds, losing that weight is not going to take place simply because the med has been discontinued. Still, some pts have had dramatic weight loss on ziprasidone and aripiprazole after being switched from olanzapine.
