1
Q

medical model

A

Views psychological conditions as sets of symptoms, causes, and outcomes, with treatments aimed at changing physiological processes
-this approach was somewhat limited, solely focused for finding cures for things rather than trying to reach wellness in the patient

Q

biopsychosocial model

A

Includes physiological processes within a more holistic view of the person as a set of multiple interacting systems

Q

what are some cons of the criteria for “maladaptive behaviour”?

A
  • not perfect criteria, drug users wouldn’t fit into the first criteria because they don’t think they’re hurting themselves
  • or in the case where a loved one has died, this can impair someone’s day to day activities but it doesn’t mean someone’s crazy

Q

the current version of DSM-V is criticized for what?

A
  • promoting over-diagnoses (ADHD)

Q

How does the DSM-V over-diagnose ADHD?

A
  • as ADHD has become it’s own disorder, the rate in the population has sky rocketed

A

25, 50

51
Q

is it possible that there is a specific gene sequence present in all people with schizophrenia that may be part of the cause?

Q

How severe are the side-effects of monoamine oxidase inhibitors and tricyclic antidepressants? What have we done to reduce these?

A
  • these both have a lot of side effects, today, we have different drugs that have less side-effects (such as SSRI)
  • the side effect of this have much less variety and are less severe, SSRIs are safe, do not lead to tolerance or withdrawal symptoms

96
Q

What is an early technological and surgical method that neurologists used to treat psychological disorders?

A
  • neurologists in the 1800s and 1900s experimented with removing regions of the brain
  • wire loops to destroy the frontal lobe
  • using an ‘ice pick’ to perform a prefrontal lobotomy (disconnect the frontal lobes from the rest of the brain)
  • created a lot of cognitive impairments
  • eliminated in the U.S. by 1970s
97
Q

focal lesions

A
  • more recent
  • small, specific damage applied to a cluster of nerve cells (avoiding widespread damage)
  • for severe psychiatric problems when all other methods failed
  • no more side effects than many drug treatments

98
Q

electroconvulsive therapy

A

Is a psychiatric treatment in which an electrical current is passed through the brain to induce a temporary seizure

99
Q

is eletroconvulsive therapy effective? what is the rate of success?

A
  • most people get the benefit after the first session
  • safe procedure, no lasting cognitive impairments, more severe risks are because of the use of anesthetic
  • 50% of patients who don’t respond to any other treatments, response to ECT
  • 25% of people end up relapsing if combined with antidepressants
100
Q

trans-cranial magnetic stimulation (TMS)

A

A therapeutic technique in which a focal area is exposed to a powerful but safe magnetic field

  • reduces depressive symptoms
  • no anesthesia or seizure
  • disrupts or enhances certain areas in the brain that are under-active or overactive, facilitating the rewiring process; as effective as ECT
101
Q

deep brain stimulation (DBS)

A

A technique that involves electrically stimulating highly specific regions of the brain

  • thin electrode-tipped wires inserted into the brain
  • instantaneous results
  • battery implanted in a persons skin, acts as a pace-maker, directly alleviating symptoms
102
Q

is deep-brain stimulation dangerous?

A

-not doing permanent damage, but invasive in the sense that you’re doing surgery (anesthetics, internal bleeding possible)
