- social/occupational dysfunction
- continuous signs of disturbance persist for at least 6 mos; must include at least 1 mo of symptoms
- symptoms cannot be due to another illness (schizoaffective and mood disorder) or due to substance use or medical disorder
positive symptoms of schizophrenia

- residual: period between psychotic episodes, in touch with reality but does not behave normally (associated with negative symptoms)
demographics of schizophrenia
- 1/100 prevalence
- occurs equally in men and women
- age of onset: 15-25 in men, 25-35 in women
- women respond better to antipsychotic meds; have a greater risk of tardive dyskinesia

- aim: relieve symptoms by unlearning maladaptive behaviors
- techniques: based on classical and operant conditioning
- treats: phobias, depression, autism spectrum, psychotic disorders, ODD/ADHD
- e.g. systematic desensitization, flooding, token economy, stimulus control, self-monitoring
classical conditioning
- pavlovian; what happens before the behavior is important
- usually deals with involuntary responses
- organism learns stimulus discrimination
- good for addictions treatment and phobias
instrumental/operant conditioning
- what happens after the behavior is important
- reinforcement: stimulus you add in that increases behavior
- reinforcement: stimulus you remove that increases behavior
- continuous vs. intermittent reinforcement schedule
- fixed interval, variable interval have most consistant response
- continuous vs. intermittent reinforcement schedule
- reinforcement: stimulus you remove that increases behavior
- punishment: unpleasant stimulus or removal of pleasant stimulus
- Does not erase habit but suppresses it; can often be ineffective unless given immediately after response; signals what is bad but doesn’t show what is good
somatization disorder
- 4+ pain issues (2 GI, 1 sexual, 1 neuro) not adequately explained by mdical causes after history, exam, labs, tests
- onset before 30 yo.
- chronic symptoms; remission is rare
- unconscious; no secondary gain
conversion disorder
- sudden and drastic loss of one or more voluntary motor and/or sensory functions suggesting neurologic etiology
- la belle indifference
- usually self-limiting with remission <1 mo
- unconscious; no secondary gain
illness anxiety disorder (hypochondriasis)
- fear or idea of having serious medical illness based on misinterpretation of bodily symtoms
- part of GAD spectrum
- symptoms must persist 6+ mo
- unconscious; no secondary gain
- Tx: SSRIs
body dysmorphic disorder
- preoccupation with imagine problem or insignificant abnormaility in sppearance (usually involves face/head)
- cannot be accounted for by eating disorder
- plastic surgery/medical interventions are common but rarely relieve symptoms
- unconscious; no secondary gain
pain disorder
- removed in DSM 5
- protracted pain severe enough to cause patient to seek help but cannot be explained by physial causes
- acute (<6 mo) or chronic (>6 mo)
- typical onset 3-4th decade
- can be disabling and cause dependence on pain meds
- unconscious; no secondary gain
factitious disorder (Munchausen’s)
- conscious feigning or production of physical/mental illness in order to recieve attention from medical personnel
- assume sick role
- primary gain: feel safe/care for
- secondary gain: feel expert at solving their medical problem
- get angry when confronted about it
- more common in medical personnel
malingering
- not in DSM 5
- not psychiatric (could be a crime)
-
conscious simulation or exaggeration of physical or mental illness to achieve secondary gain
- disability
- drugs
- leave of absence/AWOL
- symptoms improve once secondary gain is obtained
- seen more frequently in incarcerated and people in lawsuits
cognitive therapy
- problems develop as a result of errors in thinking
- aim: correct errors in logic (cognitive distortions) driven by schemas (underlying cognitive construct)
- ST; focus on cognitive restructuring, psychoedu
- treats: depression , anxiety disorders, eating disorders
cognitive behavioral therapy
- 3 fundamental propositions
- cognitive activity affects behavior (mediational model)
- cognitive activity may be monitored and altered
- desired behavior change may be affected through cognitive change
- 3 major classes of CBT
- coping skills therapies
- cognitive restructuring methods (change beliefs)
- problem solving therapies (combination of the two)
- emphasizes homework and outside session activities
dependence vs. abuse
- dependence: physiological tolerance + withdrawal
- abuse: psychological
effects of drugs and addictive behavior on brain
- act on limbic reward pathways to either:
- enhance DA release from VTA
- enhance DA effects in nucleus accumbens or related structures
- drug induced states are important motivators/ reinforces of use
- chronic use→ reward circuitry changes that promot future use (increased limbic function, decreased prefrontal cortex function)
opiate intoxication and withdrawal
- intoxication: elevated mood, pupil constriction, respiratory suppression
- Rx: naloxone to reverse
- withdrawal: don’t die but you wish you would; restless, water eyes, yawning; cramping
- Rx: methadone (full agonist) or buprenorphine (partial agonist)
EtOH intoxication and withdrawal
- intoxication: seriously you live this
- Rx: support
- withdrawal: tremor, agitation, DTs (20-30% mortality), GI, seizures, hallucinations
- Rx: benzos until stable and symptoms normalize
benzo/barb intoxication and withdrawal
- intoxication: similar to alcohol
- Rx: flumazenil for benzos
-
withdrawal: agitation, tremor, GI, seizures, hallucinations, death
- Rx: benzos until stable and symptoms normalize
stimulant intoxication and withdrawal
- intoxication: dilated pulis, psychosis
- withdrawal: crash but no death
hallucinogen intoxication
- perceptual distortion, depersonalization
- PCP/ spike: sedatives better than antipsych because rhabdo
cannabis intoxication
elevated mood, expansive thought, pupil constriction, red conjunctiva
stages of change
- precontemplation: not yet acknowledging there is a problem
- contemplation: acknowledge problem but not willing to make change
- preparation/determination
- action/willpower
- maintenance
- relapse
12 steps of AA
- admit powerless
- believe there is power greater than you

- ask God to revoew shortcomings
- make a list of person harmed and become willing to make amends
- make amends
- continue personal inventory

- spiritual awakening and promote AA to others
varenicline
- partial nicotine receptor agonist used for smoking cessation
- avoid most withdrawal
- best results
buproprion
- used for smoking cessation
- blocks reuptake/recycling of NA and DA→ desensitize DA reward circuitry so cigarette is not missed
- boxed warning: anxiety, suicidality esp in <25 yo.
