how many weeks gestation is considered premature and v. premature?
- premature birth: <37 weeks
- very premature birth: <32 weeks
what is the APGAR score and how is it used?

diagnostic criteria for schizophrenia
- psychosis is hallmark symptom, no clouding of consciousness
- 2+ of the following during 1 mo. period: delusions, hallucinations, grossly diorganized or catatonic behavior, negative symptoms (flat affect, alogia, avolution), disorganized speech (frequent derailment or incoherence)
- 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
- additional to expected behavior:
- delisions
- hallucinations
- aditation
- talkativeness
- though disorder
- responds well to most traditional and atypical antipsychotic agents
negative symptoms of schizophrenia
- missing from expected behavior
- lack of motivation
- social withdrawal
- flattended affect/emotion
- cognitive disturbance
- poor grooming
- poor/impoverished speech
- sometimes has a better response with atypical antipsychotics
course of schizophrenia
- prodromal: prior to first psychotic break (late teens, early 20s)
- psychotic/active: loss of touch with reality (associated with positive symptoms)
- 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
- role of genetics (concordance in twins) and environment (viruses? 3rd tri use of diuretics?)
neurologic abnormalities in schizophrenia
- hypofrontality (decreased use of glucose in prefrontal cortex)
- hyperactive mesolimbic pathway: positive symptoms
- hypoactive mesocortical pathway: negative symptoms
- lateral and third ventricle enlargement, decreased volume of hippocampus, amygdala, parahippocampal gyrus
- loss of cerebral asymmetry
- abnormal EEGs
NT abnormalities in schizophrenia
-
glutamate hypothesis: NMDA receptor hypoactivity? Glu is major excitatory NT and antagonists of NMDA subtype of Glu receptors aggravate and create psychosis while agonists experimentall relieve symptoms
- normal: Glu-GABA-Glu-DA
-
dopamine hypothesis: disturbed and hyperactive dopaminergic signal transduction
- normal: Glu-GABA-Glu-GABA-DA
DDx of schizophrenia
- psychotic disorder by general medical condition: B12/folate delicienct, temporal lobe epilepsy, steroid-induced
- manic phase of bipolar
- substance-induced psychotic disorder: cocaine, meth, stimulants, PCP, LSD, bath salts
- other psychotic disorders
- brief psychotic disorder
- schizophrenidorm disorder
- schizoaffective disorder
- delusional disorder
- shated psychotic disorder
Tx of schizophrenia
- all effective antipsychotics block D2 receptors in mesolimbic DA pathway
- treatment is often lifelong
- first line therapy: atypical second generation antipsychotics
- psychotherapy: LT support for patient and family, fosters compliance with drug regimen
- suicide prevention: >50% attempt suicide
diagnostic criteria for ADHD (neurodevelopmental disorder)
-
6 inattention symptoms for 6 mo (5+ if older than 17)
- poor attention to details→mistakes
- cannot sustain attention/is distracted
- does not listen
- does not follow through
- does not organize
- avoids tasks
- loses things/is forgetful
-
6 hyperactive/impulsive symptoms for 6 mo (5+ if older than 17)
- fidgets
- leaves seat
- runs/climbs
- not quiet/talks alot/blurts out/interrupts
- cannot wait turn
- several symptoms prior to age 12
- symptoms in 2+ settings
- symptoms reduce quiality of life
course of ADHD
- most often apparent at young age where age appropriate norms for paying attention and delaying gratification are not met
-
milder and more inattentive cases may not be noticed until later in life when demands are greater
- inattentiveness tends to persist more than hyperactivity/impulsivity
etiology of ADHD
- at least 76% heritable (one of the most biological illnesses)
- environmental factors: cigarette use/alcohol use in pregnancy, Pb poisoning, head injuries
neurologic abnormalities in ADHD
- hypoactive anterior cingulate
NT abnormalities in ADHD
- NE: low tonic NE firing in prefrontal cortex
- DA: low tonic DA firing in prefrontal cortex
- 5-HT: ?? controls locomotion and behavior and cognitive impulsivity
management of ADHD
-
medication is more effective than therapy
- stimulant class has greatest efficacy: risk of addiction, stunts growth, weight loss
- non stims have less efficacy: no risk of addiction, often sedating, may lower BP
- psychotherapy: behavior modification and training
- work with adults not child to help train child
risk triad of suicidality
- ideation: how often? how pervasive?
- plan: specific? well planned?
- intention
what are some symptomatic precursors to suicidality?
- anxiety
- panic attacks
- insomnia
- restlessness
- hopelessness
- helplessness
demographics of suicide
- almost always due to mental illness (usually depression)
- gender: women attempt more, men are more successful
- religion: highest completion in protestants
- race: white americans have higher rates, gap is narrowing
- age: teens and elderly are at greatest risk
genetic risks for suicide
- 5HTT gene polymorphism (resilience gene)
- ss short allele for serotonin transporter (reuptake pump) seems to convey poor resilience, incresed MDD, and suicide risk when faced with stress
- ll long allele seems protective
diagnostic criteria for MDD
-
5+ during the same 2 week period and represent change from previous functioning; at least one symptom is either depressed mood or loss of interest/pleasure
- significant weight loss or decreased appetite
- insomnia or hypersomnia
- phsychomotor agitation or retardation
- fatigue or loss of energy
- feelings of worthlessness or excessive/inappropriate guilt
- diminished ability to think or concentrate or indecisiveness
- recurrent thoughts of death, recurrent suicidal ideation
- symptoms cause significant distress/impairment in functiong
- not attributable to another condition or medication
SMIGECAPS
- Sleep disturbance

- vitamin deficiency
- obstructive sleep apnea
etiology of MDD
- ratio of monoamines and receptors is off
- monoamine receptor excess theory: leading theory
- monoamine deficiency: low levels of dopamine, serotinin, norepi
neurologic abnormalities in MDD
- stress→high glucocorticoids and low BDNF→ atrophy/death of neurons
- regain function through interventions that increased 5HT and norepi
- hypoactive dorsolateral prefrontal cortex and hyperactive amygdala
demographics of MDD
- women>men
- low estrogen= low serotinin
- MAOa gene is on X chromosome
- comorbidity of substance abuse and generalized anxiety
Tx for MDD

- front line agents: SSRIs, SNRIs, NDRIs
- MAOIs: v. effective but dangerous side effects
- tricyclics: v. effective but side effects and easy to OD on
- augmenting strategies: lithium, thyroid hormone, atypical antipsychotics (best data but high side effects)
- ECT: 80-90% effective
- therapy

- destructive behavior: physical harm to another person or immediate environment
CAM in psychology
-
folates, SAMe: low level RCT data support as effect depression treatment
- effects 1 carbon cycle and methylation; increases NTs
- St. John’s Wart: RCT and meta analysis support its effect over placebo
- mindfulness: reasonable data for anxiety control
- yogic breathing: reasonable data for PTSD and depressive symptoms
- light therapy: v. good for seasonal depression
psych genes

- antisocial: more prevalent in men
- risk factors: unmarried, impoverished, poorly educated
etiology of personality disorder
- early maternal deprivation reduces CNS serotonin levels

diagnostic criteria for mania
- distinct, abnormal, elevated, expansive (or irritable) mood > 7 days
- 3+ symptoms for 2 weeks:

- cyclothymia: chronic hypomania
bipolar 1 vs bipolar 2
- bipolar 1: mania + major depressive episode; women = men
- bipolar 2: hypomania + major depressive episode women > men
etiology of bipolar disease
- high level of monoamines, low # of receptors
- kindling hypothesis: too much neuronal limbic firing; antiepilepsy drugs via Na2+ blockade
Tx for bipolar disorder
- avoid antidepressants (increase monoamines, elevate mania)
- atypical antipyschotics: uniquely suited to treat both sides of bipolarity; block D2 receptor and 5HT2a
- pyschotherapy is good for bipolar depression but not mania
- Li: promotes neuronal health and protective factors
