Ego - meshing of id and superego
What is anaclitic depression
similar to reactive attachment disorder, often seen in orphanages - children do not relate well b/c do not have human contact like in families
encyclopedia:
a syndrome occurring in infants, usually after sudden separation from the mothering person. Symptoms include apprehension, withdrawal, detachment, incessant crying, refusal to eat, sleep disturbances, and, eventually, stupor leading to severe impairment of the infant’s physical, social, and intellectual development. If the mothering figure or a substitute is made available within 1 to 3 months, the infant recovers quickly with no long-term effects

reduced drug effect with repeated use; need higher doses to get the same effect (dose-response curve shifts right)
what is drug dependence
physiological and/or behavioral changes when you stop the drug, which are reversible by resuming drug
compare timing and severity of withdrawal symptoms for
- long acting drug
- short acting drug
- short acting drug w/ antagonist
long acting - delayed onset withdrawal and over time, mild severity
short-acting (aka metabolized/eliminated faster) - severity is more intense but shorter duration
with antagonist - withdrawal even more intense and shorter duration
what is the difference between spontaneous and precipitated withdrawal?
spontaneous- happens when you stop taking the drug
precipitated - happens when given a drug antagonist
eg opiate-dependent ppl given antagonist naloxone experience and immediate intense withdrawal / flumazenil antagonist of benzos
(duration of precipitate withdrawal depends on duration of action of antagonist)
What is psychological dependence
what is physical dependence
intense craving and compulsive drug-seeking behavior
*is the key factor in addiction (rather than avoidance of withdrawal or reinforcement)
physical dependence = stereotyped withdrawal syndrome that is reversed by resumption of use

thiamine (MUST give thiamine AT LEAST 2H before starting dextrose fluids!!)
folic acid
multivitamins
how does buprenorphine’s unique pharmacology make it great for treating opioid dependence?
- partial mu receptor agonist
- high affinity for mu receptors = can displace full agonists and resist being displaced itself
- low intrinsic activity = there is a ceiling for its mu agonist effects incl respiratory depression (hard to overdose on it)
- dissociates slowly from receptor = prolonged suppression of opioid withdrawal symptoms
**Buprenorphine’s partial agonist effects can act as an antagonist in ppl dependent on full-agonist opioids, can PRECIPITATE withdrawal syndrome!!
4 meds for alcohol dependence and MOA
disulfiram (antabuse) - blocks acetaldeyhyde dehydrogenase
- can cause hepatoxicity
- best in monitored setting (parole, probation)
acamprosate - inhibits glutamatergic system

naltrexone - blocks opioid receptors
- reduced craving
- reduce alcohol use (can give to ts who aren’t abstinent)
- tablets or monthly IM injection
gabapentin - not FDA approved for alcohol dependence but similar efficacy as acamprosate
-better for pts whose drinking is driven by anxiety

four aspects of DSM-5 definition of substance use disorder
Impaired control
- using more or for longer than intended
- persistent desire or unsuccessful efforts to cut/control use
- lots of time spent in activities need to obtain substance
- craving
Social consequences
- fail to fulfill work/school oblig bc of time spent high
- continued use despite negative social feedback or interpersonal prob
Risky use
- recurrent use in physically hazardous situations
- recurrent use despite psychological disturbance or medical problem
Pharmacological - tolerance, withdrawal
severity is mild, mod, severe based on number of symptoms
what is the Allostasis/ Reward-deficiency hypothesis of addiction
nothing motivates you but your drug of choice
repeated drug intoxication affects motivational neurocircuitrity so that you have a progressively decreasing set point of mood - neurobiologically incapable of strong motivation toward non drug rewards
describe what’s happening in the brain in the three stages of addiction
Intoxication- activation of brain’s reward regions enhanced by conditioned cues in areas of increased sensitization
Withdrawal- activation of brain regions involved in emotions results in negative mood and enhanced sensitivity to stress (bc incr corticotropin-releasing factor)
Preoccupation- decreased function of prefrontal cortex leads to inability to balance strong desire for drug with with will to abstain –> relapse and reinitiates cycle of addiction
how do dopamine receptors change in addiction
lose Dopamine receptors
incentive salience model of addiction
Sighs and sounds associated with drug effects acquire incentive salience and start controlling behavior by themselves
what is the impulsivity hypothesis of addiction
imbalance between impulsive and executive systems
strongly discount rewards with delayed receipt
poor future orientation
drug abuse can also cause impulsivity by frontocortical damage (which is the part of brain needed to stop abusing)
action of stimulants (e.g. cocaine)
bind DAT and NET (little SERT) thus preventing reuptake of dopamine and norepi

what is the monoamine theory of depression?
- evidence supporting this theory?
- evidence against?
depression could be related to deficiency of monoamine NT (usually NE or serotonin) at functionally important receptors in the CNS
(*mania results from excess neurotransmitter)
SUPPORT:
- reserpine (blocks VMAT and depletes NT stores) can mimic depression
- ampehtamine-like stimulants (which facilitate NT neurotransmission) enhance mood
- decr urine, blood, or CSF levels of NE metabolites in depression
- both MAOI and TCAs enhance monamine transmission (Tho different mechanisms)
AGAINST:
- time course of antidepressant enhancement of monamines and clinical response differ
- some drugs that also enhance monoamines aren’t useful as antidepressants (eg amphetamines)
- newer antidepressants are quite selecective for blockade of either NE or serotonin uptake yet are all effective
TCAs have lots of side effects, as they also have affinity for what receptors

but may be more epileptogenic
how do antidepressants change receptor regulation
decr number of post-synaptic beta-aderenergic receptors

and/or
decrease the functional coupling of these receptors to their effector systems
5HT1A receptors are coupled to what signaling pathway
