Dopaminergic pathways
Glutamate hypothesis
Neurodevelopment hypothesis
Later environment stressor
Multiple HIT model
48
Explain genetic markers in regards to the development of schizophrenia
Identical twins have a 50% risk of both having it which means there is an environmental piece to it
Can be a biological environment
Behavioral markers
Smooth-pursuit eye movement
Tracking deficits
People with SCZ and relatives
49
Explain brain structure and function in regards to the development of schizophrenia
Pyramid
Decreased brain volume
Enlarged ventricles
Reduced volume of the thalamus
Abnormalities in the temporal lobe areas
Hypofrontality
Temporal cortex, language areas
50
Describe the stages in the brain structure and function pyramid from bottom to top
Disorganized cytoarchitecture:
Cells line up with each other but with schizophrenia they tend to not have as uniformed of a structure
Disrupted brain development in adolescence:
Things are going wonky
Loss of gray matter:
Cell bodies are dying, neurodegeneration
Loss of white body:
Fewer connections
Attentional and working memory deficits:
As the cells start deteriorating it is much harder for them to get their jobs done
Impaired social cognition:
Not understanding what is happening socially
51
What effect does reduced volume of the thalamus have?
Gateway for processing all incoming sensory info
Call center director
Relays information less effectively, can't understand
Likely due to disorganized (difficulty with) perception and thoughts
52
What effect does hypofrontality have ?
Reduced neural connectivity
Excessive synaptic pruning (use it or lose it)
Major DA pathway (PFC inhibits DA in limbic system)
Working memory
Representing sensory info to guide behavior
Disorganized behavior and speech, thought disorder
53
What effect does the temporal cortex have?
Broca’s area: speech production
Wernicke’s area: language comprehension
Broca's area is active during an auditory hallucination since it is producing the voice
54
Explain original DA hypothesis in regards to the development of schizophrenia
Schizophrenia ↔ DA excess
Drugs ↑ DA
Result in schizophrenia like behavior
E.g., amphetamine, L-Dopa for Parkinson’s disease
Drugs ↓ DA
Reduce schizophrenia like behavior
E.g., neuroleptics
Do not treat negative symptoms
*Drugs that increase DA increase schizophrenia and drugs that decrease DA decrease schizophrenia
55
Explain revised DA hypothesis in regards to the development of schizophrenia
Negative symptoms
↓ DA in cortical regions
Underactivity at D1 receptors
Positive symptoms
↑ in DA subcortical regions
Pre synaptic
Too much produced and released into synapse → overactivity at D2 receptors
Post synaptic
Some findings of too many D2 receptors
56
What's the primary difference between the original and revised DA hypotheses?
The original believes the too much DA increases schizophrenia where too little decreases it but only in regards to positive symptoms
The revised accounts for both positive and negative symptoms
57
Explain dopaminergic pathways in regards to the development of schizophrenia
Mesolimbic pathways (positive symptoms)
Nucleus accumbens (NA)
Ventral tegmental area (VTA)
Where a ton of the DA is produced and it is sending it to the NA
Excess activity here in positive symptoms
Mesolimbic pathways (negative symptoms)
The VTA sends DA to the frontal cortex and when there is more DA there it the limbic system can’t tell it to stop
Both pathways are reversed
58
Explain glutamate hypothesis in regards to the development of schizophrenia
↓ Glutamate
PCP and ketamine → schizophrenia like behavior
Underactivity at NMDA receptors
DA receptors also inhibit glutamate activity so too ↑ DA activity leads to too ↓ glutamate activity which increases schizophrenia symptoms
Glutamate plays a role in learning, memory, neural processing
Explains problems with attention, working memory, excessive function
59
Explain neurodevelopment hypothesis in regards to the development of schizophrenia
Silent lesion
Neuromotor, cognitive and behavioral abnormalities:
Smaller head circumference at birth
Slower to reach developmental milestones
Higher rates of left-handedness
Congenital minor physical and craniofacial anomalies:
Velocardiofacial syndrome
Gestational and perinatal exposures:
Viral infection
Early nutritional deficiencies and maternal stress
Pregnancy and birth complications
Maternal starvation (1st trimester
Hypoxia (less oxygen)
Maternal viral infections
60
Explain the silent lesion hypothesis
Abnormalities lie dormant until normal developmental processes expose problems
Brain makes up for the loss and in adulthood you realize you are missing a piece
Related to prefrontal cortex development
Problems in the neural system are present way before you actually see the symptoms
61
Explain later environmental stressor in regards to the development of schizophrenia
People with schizophrenia are 2x as likely as the general population to smoke cannabis
An extensive study found if people consumed a lot of weed at the age of 14 that increased risk later in life
Could be caused from cell death due to weed
Diathesis-stress
COMT gene
Breaks down proteins
62
What relationship do COMT alleles have to risk of schizophrenia and weed usage?
Met → high DA
There is no difference in schizophrenia development if you use weed in adolescents with 2 met genes
Val → lower DA
People with one met and one val gene have a increased risk of schizophrenia if they consume weed and a very low risk if they do not

Inconsistent attention:
Striatum + frontal lobes + posterior periventricular region (controlling and directing attention)
Interconnected with sensory cortices
Act as a gate
Important information registers
Irrelevant noise filtered out
They are underactive so there is attention everywhere, very open to stimuli
Sensory cortices flooded with incoming messages which lead to high blood flow

Traits (negative emotional responsiveness):
Neuroticism
Impulsivity
5x more common among first degree relatives
Relatives - impulse spectrum disorders (e.g., ASPD, substance abuse)
126
Biopsychosocial model of Borderline Personality Disorder: Etiology/Presentation: Bio
Decreased orbitofrontal volume which leads to impulsivity, aggression, mood instability
Decreased hippocampal volume which leads to stress overreactivity (anxiety), increased fear responses
Amygdala hyperactivity, easier conditioning to fear, affective lability
Lower 5-HT leads to impulse behavior, disinhibition
127
How is amygdala hyperactivity related to BPD?
Hypervigilance
Emotional dysregulation
Neutral = threatening
128

Guarantee of right and freedoms
No arbitrary detainment or imprisonment
Equality before law
No discrimination
156
What is the difference between privilege and privacy in confidentiality?
Privlidge:
Right to refuse to disclose information to legal system (in all circumstances)
E.g., lawyer-client communication
Privacy:
Right to choose information being shared (in most circumstances)
E.g., clinician-clinet communication
157
What does confidential communication mean in clinician-client communication?
Communication is private
Client chooses whether and to whom info can be disclosed (in most circumstances)
Law against breaching confidentiality
158
What are the expectations to clinician-client confidentiality?
Imminent risk to self or others
Suspected harm to a child or dependent adult (and guardian will not protect)
Driving while intoxicated
Court subpoena
159
What allows the CPA code to breach confidentiality?
Clinician must breach confidentiality when and 3rd party identifiable victim or class of victims is believed to be at risk
160
What are some issues in confidentiality?
Clinican efforts to reduce liability:
Asking fewer (important) questions
Vaugue language in session motes so you cannot be held reliable
Who is the client?
Organization vs patient
Parent vs child
Infant act, if you believe the child can consent
161

Criminal commitment
Civil commitment
162

Functional
Knowledge of right vs wrong
Nonfunctional
Impulse to act is irresistible
165
What is neurolaw?
Evidence of disorder neural structure and function = sufficient to alter sentence (held less responsible)
Activation in areas consistent with impulse urges vs inability to control urges
166
Explain volitional control vs irresistible urges in murderers
Neural systems - checks and balances
Lower self-reflective PFC
More active impulse from amygdala
Impulsive murderers had high subcortical and low PFC, less brain matters
Predatory murderers high subcortical and normal PFC, control and plan
167
What is civil commitment?

Only to prevent physical harm
Denying personal freedom is serious
Softer standards discriminate against people with mental illness and are paternalistic

Dangerousness is difficult to predicit
Need to protect vulnerable persons
171
How do you predict dangerousness?
Strongest predictors:
Psychopathy scores

Home care for people with serious mental illness
Community mental health centres as access points
Increase forensic beds
Increase mental health workers in jails
Most effective medications first
Increased early detection and defragment intervention in children
24hr information/crisis line for appropriate referrals
