chapter 15 Flashcards
what is psychotherapy?
treatment of mental health disorder by psychological rather medical terms
what is trepanation
drilling holes into an individuals skull to “release demons” that were thought to be the cause of mental illnesses
what is institutionalization
separating individuals with mental illnesses from society into a hospital or restricted environment
what is efficacy
the ability for research to produce desired outcomes based on research protocols that are strictly controlled
what is effectiveness
the ability for research to produce desired outcomes based on applied research protocols
what is the function of typical (1st gen) anti-psychotics
reduces amt of dopamine activity in the brain
what is the role of dopamine un people who have psychotic disorders
to produce symptoms similar to those of psychosis
what can an increase in dopamine lead to
anxiety, agitation, and hallucinations
what are extrapyramidal symptoms
serious side effects of antipsychotic medications that include physical rigidity/involuntary body movements
what are tardive dykinesia
involuntary movement in the face, tongue or arms which usually occurs when stopping anti-psychotic drugs
what is the function of atypical (2nd gen) antipsychotics
they act on dopamine and serotonin in the brain
what is the theory of depression
caused by are result of an imbalance of specific brain chemicals known as “monoamine neurotransmitters”
what are the three main classes of antidepressants?
monoamine oxidase inhibitors, tricyclic antidepressants, and selective serotonin reuptake inhibitors
what is the function of monoamine oxidase inhibitors
prevented the breakdown of serotonin, norepinephrine and dopamine remain which allowed them to stay in the synapse for a longer time which is a good thing
What are the four types of biological treatment for mental disorders
- Medications
- Electroconvulsive therapy
- psychosurgery
- transcranial magnetic stimulation
How did chlorpromazine work
it blocked dopamine receptors, but also made patients sleepy and had significant side effects
How do anti-anxiety benzodiazepines work
they facilitate GABA neurotransmitter activity to inhibit anxiety, but are easily tolerated and contain withdrawal symptoms
What are reuptake inhibitors (most common ones today)
they prevent neurotransmitters (have a greater effect on serotonin and less effect on norepinephrine and dopamine) from being recycled (taken back up) which increases the concentration of them in the synapse
what is electroconvulsive therapy (ECT) ?
induces controlled seizures and is safe + effective, but needs to be repeated multiple times
what is transcranial magnetic stimulation
uses electromagnetic currents to stimulate portions of the brain and produces small magnetic pulses that go about an inch into the brain to increase/decrease neuronal activity
What is psychosurgery
operation where psychological disorders are addressed using surgical processes like trepanation
