lesson 18 psychopathology part 2 Flashcards
highest risk schizhophrenia diasthesis
highest risk is identical twin
genetic vulneralbility
schizophrenia stresses
social isolation (people in mexico fare better than people in america because they arent isolated)
family dynamics (ways families express emotions, fighting)
two classes of treatments for mental disorders:
psychopharmacology (meds) vs psychotherapy (change mindset)
experiment for psychopathology treatment
experiment where they gave people with ocd:
1) anti anxiety meds
2) psychotherapy
-change in brain is the same whether through drugs or therapy, so behavior/cognitions has also been changed
how neurons communicate with each other (psychopharmacology)
synapse: when action potential fired through neuron, chemical released from axon terminal of presynaptic neuron and float over to receptors on dendrites/soma of postsynaptic neuron- now either more likely to fire or less
neurotransmitter
chemicals neurons use to communicate over synapse
history of schizophrenia
before 1940s, outcomes of people with disorder were bad, left to fend for themselves
then frontal lobotomies used to decrease associated symptoms
(caused people to be disconnected)
then 1950s developed by accident drugs that have effect on symptoms (antihistamine, dopamine antagonists)
antagonist decreases action of dopamine
thorazine shuffle
one of the first drugs that helped with schizophrenia symptoms, but caused parkinsons’ like side effects where muscles lock up and person moves slowly
how do drugs impact schizophrenia
they diminish the symptoms but dont get to the root of the problem
selective serotonin reuptake inhibitors (depression)
serotonin left over in synapse
drugs for depression inhibit reuptake of serotonin (being taken up by trash molecules to be reused)
so now more serotonin left over (levels increase)
gaba (anxiety)
gaba in brain’s main inhibitory neurotransmitter
increase gaba levels, brain activity less excited (inhibited more), anxiety decreases
main drugs for psychopharmacology
ssri (depression)
anti anxiety drugs (anxiety)
anti psychotic (schizophrenia)
lithium (bipolar)
pros for using drugs for mental illness
easy to administer
cheap
people will actually take the drug
cons for using drugs for mental illness
difficult to get people to adhere to drug regimens because they like symptom of disorder (drugs deaden experiences)
not training patient to think differently; if they stop taking meds symptoms will come back
what is psychotherapy
intervening directly at level of the mind, behavior, motion
