Schizophreniform Disorder
38. Introduction
Schizoaffective disorder is a serious mental
illness that affects about one in 100 people.
It is serious mental illness that has features of
two different conditions:
1. schizophrenia
2. an affective (mood) disorder that may be
diagnosed as either
major depression or bipolar disorder.
Schizoaffective Disorder
39. Schizoaffective disorder is a lifelong illness that can
impact all areas of daily living
Most people with this illness have periodic episodes,
called relapses, when their symptoms surface.
there is no cure for schizoaffective disorder,
symptoms often can be controlled with proper
treatment.
Schizoaffective Disorder
40. Symptoms
Schizoaffective Disorder is characterized
by schizophrenia with one of the following:
1) Major Depressive Episode(must include
depressed mood)
2) Manic Episode
3) Mixed Episode
Schizoaffective Disorder
41. Management
combination of medications and counseling.
Treatment depending on the type and severity of
symptoms, and whether the disorder is depressive-
type or bipolar-type.
Medications:
1- Antipsychotics
paliperidone (Invega) and other antipsychotic
medications that may be prescribed include
clozapine (Clozaril), risperidone (Risperdal),
olanzapine (Zyprexa) and haloperidol (Haldol).
Schizoaffective Disorder
42. 2-Mood-stabilizing medications.
Include lithium (Lithobid) and divalproex
(Depakote). Anticonvulsants such as
carbamazepine (Carbatrol, Tegretol, others)
and valproate (Depacon).
3-Antidepressants.
Common medications include citalopram
(Celexa), fluoxetine (Prozac) and
escitalopram (Lexapro).
Schizoaffective Disorder
43. Psychotherapy
Psychotherapy and counseling.
Family or group therapy.
Treatment can be more effective when people
with schizoaffective disorder are able to discuss
their real-life problems with others.
Supportive group settings can also help decrease
social isolation and provide a reality check
during periods of psychosis.
Schizoaffective Disorder
45. Definition
Delusional disorder is an illness
characterized by the presence of
nonbizarre delusions in the absence of
other mood or psychotic symptoms
Delusional Disorder
46. Epidemiology
- The prevalence of delusional disorder in the USA is estimated in
theDSM-IV-TR to be around 0.03% .
- considerably lower than the prevalence of schizophrenia (1%) ,
mood disorders (5%) .
- The mean age of onset is 40 years .
- Men are more likely than women to develop paranoid
delusions .
- women are more likely than men to develop delusions of
erotomania .
Delusional Disorder
47. Etiology
(a) Genetic :
Not a variant of schizophrenia or mood disorders. No
increase in first degree relatives.
(b) Neurological conditions :
- limbic system and the basal ganglia disorders .
- Patients tend to have complex delusions similar to
those in patients with delusional disorder .
(c) Psychodynamic Factors :
- socially isolated persons .
- - Abuse .
Delusional Disorder
48. Current Diagnosis Criteria
* DSM-IV-TR
defines delusional disorder with the
following criteria:
A) Non bizarre delusions .
B) Criterion A for schizophrenia has never been met .
C) functioning is not markedly impaired and
behavior is not obviously odd or bizarre.
D) If mood episodes have occurred concurrently with
delusions, their total duration has been brief relative
to the duration of the delusional periods.
E) The disturbance is not due to a drug of abuse,
medication or general medical condition.
Delusional Disorder
49. Clinical Features
- Mental State Examination usually normal except
presence of abnormal delusional beliefs.
- Mood and affect are consistent with delusional
content.
- Tactile and olfactory hallucinations may be present
if they are related to delusional theme.
- The thought content is notable for systematized, well-
organized, nonbizarre delusions that are possible to
occur.
Delusional Disorder
50. - The thought process is usually not impaired;
however, some circumstantiality and idiosyncrasy
may be observed.
- Patients usually have little insight and impaired
judgment regarding their pathology.
- Assessment of homicidal or suicidal ideation is
extremely important in evaluating the patients.
erotomanic, jealous, and persecutory > ↑violence
Delusional Disorder
51. Subtypes of delusional disorder
Persecutory
Most common type
believes that they are being persecuted and
harmed
The delusions are systematized, coherent, and
defended with clear logic. (contrary to schizo)
No deterioration in social functioning and
personality
emotional distress such as irritability, anger, and
resentment may resort to violence
Delusional Disorder
52. Erotomanic :
Thinks that another person, usually of higher status, is
in love with the patient.
F>M
Leads to stalking behaviour (pursuing the lover,
texting, phone calling, etc).
Delusional Disorder
Grandiose
believes that they possess some great and
unrecognized talent, have made some important
discovery, have a special relationship with a
prominent person, or have special religious insight.
53. Jealous
Pathological jealousy
M>F
her or his spouse or lover is unfaithful.

homicide.
Delusional Disorder
54. Somatic:
delusions around bodily functions and sensations.
Non-bizarre.
most common are the belief that one is infested
with insects or parasites.
Patients are totally convinced in physical nature of
this disorder.
Delusional Disorder
57. 3. Paranoid Personality Disorder
- no true delusions. Overvalued ideas
- enduring, deeply ingrained
4. Paranoid Schizophrenia
- auditory hallucinations
- personality deterioration
- disturbance in role functioning
5. Mania - Grandiose delusions, but these are
clearly secondary to primary and
prominent mood disorder
6. Depression - Mood symptoms prominent
(depressed)
- delusions are secondary
Delusional Disorder
58. Management Plan:
* Investigations:
- To rule out substance abuse: drug screening .
- To rule out medical causes: CT, MRI.
- To choose a proper medication (prevent side
effects)
- Blood glucose level, lipid profile (anti-psychotics)
RFT, thyroid FT, LFT, ECG (Lithium & others)
Delusional Disorder
59. * Treatment
A) if suicidal or homicidal ideas present
(hospitalization ) or if refuse eating .
B) Medication:
- Antipsychotics- Pimozide .
- If there are somatic delusion & depressive symptoms
Antidepressants (SSRIs) may be used
C) Should also add supportive and educational
psychotherapy sessions to help the patient (to
improve insight & compliance).
Delusional Disorder
61. Acute psychotic condition that
involves the sudden onset of psychotic
symptoms, which lasts 1 day or more
but less than 1 month. Remission is full,
and the individual returns to the
premorbid level of functioning.

Treatment
Brief Psychotic Disorder
68. Case
A 28-year-old woman taking care of her
schizophrenic husband starts believing her
husband’s claim that he invented the telephone.
When she went abroad for a few months, her
beliefs disappeared.
69. Also known as folie à deux, shared
psychotic disorder is diagnosed when a
patient develops the same delusional
symptoms as someone he or she is in a
close relationship with. Most people
suffering from shared psychotic disorder
are family members.
70. DSM-IV-TR Diagnostic Criteria for
Shared Psychotic Disorder
A delusion develops in an individual in the context
of a close relationship with another person(s), who
has an already-established delusion.
The delusion is similar in content to that of the
person who already has the established delusion.
The disturbance is not better accounted for by
another psychotic disorder (e.g., schizophrenia) or
a mood disorder with psychotic features and is not
due to the direct physiological effects of a
substance (e.g., a drug of abuse, a medication)
or a general medical condition.
71. PROGNOSIS
Twenty to 40% will recover upon removal
from the inducing person.
Shared Psychotic Disorder
72. TREATMENT
The first step is to separate the patient from the
person who is the source of shared delusions
(usually a family member with an underlying
psychotic disorder).
Psychotherapy should be undertaken.
Antipsychotic medications should be used if
symptoms have not improved in 1 to 2 weeks
after separation
Shared Psychotic Disorder
74. POST PARTUM PSYCHOSIS
Postpartum psychosis (sometimes called puerperal
psychosis) is an example of psychotic that occurs
in women who have recently delivered a baby.
The incidence of postpartum psychosis is about 1
to 2 per 1,000 childbirths.
About 50 to 60 percent of affected women have
just had their first child.
About 50 percent of the affected women have a
family history of mood disorders.
Most available data suggest a close relation
between postpartum psychosis and mood
disorders, particularly bipolar disorder and major
depressive disorder.
Postpartum psychosis
75. Clinical features:
The symptoms of postpartum psychosis
can often begin within days of the
delivery, although the mean time to
onset is within 2 to 3 weeks and almost
always within 8 weeks of delivery.
Insomnia, restlessness and emotional
liability
Progress to confusion, delusions.
Thoughts of harming self or baby
characteristic
Postpartum psychosis
76. Treatment:
Postpartum psychosis is a psychiatric
emergency.
Antipsychotic medications and lithium often in
combination with an antidepressant, are the
treatments of choice.
Psychotherapy is indicated after the period of
acute psychosis.
Changes in environmental factors may also be
indicated.
Postpartum psychosis
Echolalia: immediate and involuntary repetition of words
Simple schizophrenia (CD10)1- There is slow but progressive development, over a period of at least 1 year, of all three of the following:
A-a significant and consistent change in the overall quality of some aspects of personal behavior, manifest as loss of drive and interests, aimlessness, idleness, a selfabsorbed attitude, and social withdrawal;
B- gradual appearance and deepening of “negative†symptoms such as marked apathy, paucity of speech, underactivity, blunting of affect, passivity and lack of initiative, and poor nonverbal communication (by facial expression, eye contact, voice modulation, and posture);
C- marked decline in social, scholastic, or occupational performance.
2-At no time are there any of the symptoms referred to in criterion G1 for general schizophrenia, nor are there hallucinations or well-formed delusions of any kind; i.e., the individual must never have met the criteria for any other type of schizophrenia or for any other psychotic disorder.
3-There is no evidence of dementia or any other organic mental disorder.
