Psych Flashcards
mature defenses
mature adults wear a SASH sublimation - social unacceptable impulses are unconsciously transformed into social acceptable ones altruism suppression humor
infant deprivation effects
…
reactive attachment disorder - infant withdrawn/unresponsive to comfort
deprivation for 6+ mo –> irreversible changes
child abuse
child avoid eye contact during exam
usu biological mother
40% of deaths occur in kids < 1 yo
ADHD
treat with stimulant = methylphenidate +/- CBT
alternatives - atomoxetine (NE reuptake inhibitor), guanfacine (a2 receptor antagonist, so it can also treat HTN), clonidine (a2 agonist)
Rett syndrome
XD, seen in girls (affected males die utero)
de novo mutation in MECP2 (important for normal function of nerve cells)
around age 1-4 - regression, loss of verbal abilities, ID, ataxia, stereotyped hand-wringing
Tourettes
tics persist for > 1 yr
associated with OCD and ADHD
use typical antipsychotics for intractable, distressing tics - fluphenazine & pimozide antipsychotics, tetrabenazine (anti-chorea drug)
disruptive mood dyregulation disorder
~temper problems seen in kids younger than 10 yo
treat with psychostimulant, antipsychotic, CBT
orientation
order of loss: time –> place –> person
Korsakoff syndrome
anterograde > retrograde amnesia
anterograde - means decreased ability to form new memories
dissociative amnesia
dissociative amnesia - usu subsequent to trauma or stress
dissociative fugue - abrupt travel or wandering…
delusional disorder
fixed, persistent false belief system lasting 1+ mo
-erotomaniac, grandiose, persecutory, jealous, somatic (believing bodily functions and sensations are abnormal)
psychotic features absent
manic episode
lasting at least 1 week - elevated/irritable mood with increased energy/activity
ddx requires hospitalization of 3/DIG FAST Distractibility Irresponsibility Grandiosity - inflated self-esteem Flight of ideas - racing thoughts Activity/psychomotor agitation Sleep - decreased Talkativeness/pressured speech
pts with 1(+) lifetime manic episode are ddx with BPD1
hypomanic episode
no psychotic features
lasts at least 4 consecutive days
postpartum psychosis
treat with hospitalization and atypical antipyschotic
ECT is a second line
grief
denial anger bargaining depression acceptance pathological grief (6+ mo) is persistent and causes functional impairment --- major depressive episode
ECT
grand mal seizure in anesthetized pt
adverse effects - …partial anterograde/retrograde amnesia resolving in 6 months
safe in pregnancy
panic disorder
treatment: CBT, SSRIs, venlafaxine
OCD
CBT, SSRIs, and clomipramine (=TCAD)
PTSD
treatment: CBT, SSRIs, venlafaxine (same as for panic disorder)
prazosin can reduce nightmares
v.s. acute stress disorder - similar, lasts 3d-1 mo
conversion disorder
aka functional neurologic symptom disorder - under the somatic symptom/related disorders
loss of sensory or motor function, following acute stressor
- internal inconsistency of symptoms
pt is aware of but sometimes indifferent toward symptoms
anorexia
…
refeeding syndrome - increased insulin –> hypophosphatemia –> cardiac complications
-refeeding involves giving glucose –> increases insulin –> insulin shifts K and P into the intracellular space
buproprion contraindicated
sexual dysfunction
drug side effects - antihypertensives, antipsychotics/SSRIs, ethanol
sleep terror
occurs during slow-wave/deep (stage N3 sleep)
occurs during non-REM sleep - so no memory of arousal episode
narcolepsy
caused by decreased hypocretin (orexin - regulates arousal, wakefulness, and appetite) production in lateral hypothalamus
- associated with hypnagogic or hypnopompic (just before awakening) hallucinations
- nocturnal and narcoleptic sleep episodes that start with REM sleep = sleep paralysis
- cataplexy - loss of muscle tone following ex laughter
strong genetic component
treatment: daytime stimulants (amphetamines, modafinil - weak dopamine reuptake inhibitor) and nighttime sodium oxybate (GHB)
stages of change
- ) precontemplation
- ) contemplation - acknowledging there is a problem but not yet ready/willing to make a change
- ) preparation/determination
- ) action/willpower
- ) maintenance
- ) relapse
alcohol withdrawal
alcohol binds to GABAa receptors - chronic alcoholics have decreased GABA sensitivity
- alcohol withdrawal decreases inhibitory tone
6-48hrs - withdrawal seizures
12-48hrs - alcoholic hallucinosis, visual, delirium
48-96hrs - delirium tremens, classically occurs post-surgery
-delirium tremens - autonomic hyperactivity, electrolyte disturbances, respiratory alkalosis, fever
alcoholism - …peripheral neuropathy, testicular atrophy
- treat with… benzos, acamprosate (helps with withdrawal), naltrexone
- benzos - chlordiazepoxide, lorazepam, diazepam
opioids
use - pinpoint pupils
OD - seizures
withdrawal - muscarinic stimulation
- develop tolerance to everything but constipation and miosis
long term use
- increased turnover of receptor downregulation and decoupling
- upregulation of NMDA receptors
- -> tolerance and opioid-induced hyperalgesia (due to increased pain sensitivity)
- partial agonists such as buprenorphine can precipitate withdrawal - because it binds strongly (can prevent the binding of other opioid agonists) but has low activity
barbiturates
low safety margin! - dont mess with Barb
treat OD with symptom management
withdrawal - delirium, life threatening CV collapse
benzos
greater safety margin
treat OD with flumazenil - but flumazenil can cause seizures
withdrawal - anxiety, perceptual disturbances, psychosis, etc.
stimulants
amphetamines, cocaine, caffeine, nicotine
withdrawal - includes sleep disturbance, vivid nightmares
amphetamines
use - …pupillary dilation
OD - cardiac arrest, seizures
treat with benzos
cocaine
inhibits NE uptake by pre-synaptic neurons –> NE binds to a1 receptors on vascular smooth muscle –> vasospasm
use - pupillary dilation, hallucinations (tactile),
treat with a-blockers, benzos, DONT give b-blockers
- b-blockers are withheld from cocaine users with heart disease
- why? - b-blockers can exacerbate vasospasm, unopposed a effect and b2 receptors blocked –> vasodilation inhibited
hallucinogens
PCP, LSD, marijuana, MDMA (ecstacy)
PCP
violence –> trauma is the most common complication
nystagmus
treat with benzos
LSD
perceptual distortion, psychosis
droNABINOl
uses - antiemetic, appetite stimulant (AIDS)
