2. delusions of reference
3. thought broadcasting
4. thought insertion
Perception
hallucinations (usually auditory)
- most commonly speak directly to them in form of criticisms

1. catatonic stupor, or rigidity, or excitement
2. waxy flexibility
prevalence of schizophrenia
1. in adults: 1.3%
2. 1 million in US treated each yr
3. 15% of all treated for behavioral problem
4. occupy 50% of the beds in facilities for mentally disordered and retarded
5. occupy 25% of all hospital beds
Disorganized schizophrenia
1. frequent incoherence (neologisms)
2. absence of systematized delusions ( set of beliefs that fit together)
3. blunted, inappropriate or silly affect

4. hallucinations with persecutory or grandiose content
Type I Schizophrenia
1.positive symptoms (i.e. hallucinations)
2. abrupt onset
3. preserved intelligence
4. more favorable response to anti-psychotic drugs
Type II Schizophrenia
1.negative symptoms(i.e. apathy, withdrawl)
2. gradual onset
3. greater chronicity and intellectual impairment
4. poorer response to anit-psychotic drugs
Familial and twin studies
1. incidence 4x greater in first degree relatives of a schizophrenic than in general population
2. the closer the genetic relationship between a schizophrenic and a relative, the higher in the concordance rate
concordance rates among family and twins
spouses 1-2%
fraternal twins (DZ) 14%
identical twins (MZ) 47%
Adoption studies
adopted at high risk (HR) children are more likely to develop schizophrenia than adopted (LR) children
cross-fostering studies
HR & LR children placed in families in which:
1. a parent is subsequently diagnosed as schizophrenic
2. both parents are not schizophrenic
cross-fostering study findings
1. HR children are twice as likely as LR children to develop schizophrenia regardless of adoptive parents
2. LR children at no increased risk when raised by a schizophrenic parent

5. has potentially fatal side effect
6. costs $9000/yr
7. used sparingly on treatment resistant patients
cortical
abstract thought, concrete thought, affliation, attachment
limbic
sexual behavior, emotional reactivity, motor regulation
midbrain
"arousal", appetite/satiety, sleep
brainstem
blood pressure, heart rate, body temperature
cortical modulation ratio
the relative "power" of the cortical and limbic brain regions to modulate the more primitive, reactive, output of the brainstem and midbrain
psychotherapy
a conversation between two or more people with therapeutic intent
ratio with optimal developmental experience
corticol=12
limbic= 8 ______ 20
midbrain= 6
brainstem= 4 ______10
ratio= 2.0
Developmental trauma (domestic violence, physical abuse) will alter the coritcol modulation ratio
Corticol= 12
limbic= 8 ______ 20
midbrain= 8
brainstem= 6 _____ 14
ratio= 1.4
developmental neglect (emotional or experiential deprivation) will alter the ratio
corticol = 10
limbic = 6 ______ 16
midbrain = 6
brainstem = 4_____ 10
ratio= 1.6
neglect and trauma: a malignant combination
corticol= 10
limbic= 6 _____ 16
midbrain = 8
brainstem= 6 _____14
ratio= 1.1
