Q

biological view of causes of unipolar depression

A
  • genetic factors: genetic predisposition for depression
  • biochemical factors: unbalanced levels or neurotransmitters, especially low norepinephrine and serotonin activity. hormones and HPA pathways might also have a relationship with depression
  • brain anatomy: low activity in the PFC, small hippocampus, less neuronal growth, high activity in the amygdala, small and more active subgenual cingulate, problematic interconnectivity between these structures
  • immune system: prolonged stress causes immune dysregulation, which can contribute to depression

Q

behavioral dimension

A

when there is no sufficient reward, people might lose interest to taking part in activities, contributing to depressed feelings

24
Q

negative thinking

A

some people develop negative attitudes, leading to three types of maladaptive thought patterns (cognitive triad): experiences, self-view, and ideas about the future are interpreted in negative ways. depressed people also suffer from automatic thoughts = ongoing thought-chain that keeps suggesting pessimistic things

25
Q

learned helplessness

A

depression occurs when people think that they do not have control over rewards and punishments in their life and that they are responsible for this helplessness
- attribution helplessness theory: attribution to some internal and stable cause results in depression

26
Q

biological view of treatments of unipolar depression

A
  • electroconvulsive therapy (ECT): sending electric signals through the brain, which activate different brain areas, creating a mini seizure, relieving depression
  • antidepressant drugs
  • brain stimulation
27
Q

MAO inhibitors

A

slow production of enzyme MAO, enzyme breaks down norepinephrine, so MAO blocks this which relieves depressive symptoms

28
Q

tricyclics

A

block re-uptake of norepinephrine and serotonin, stay longer in the synaptic cleft, stimulating neighbor cells

29
Q

selective serotonin re-uptake inhibitors (SSRIs)

A

block re-uptake of serotonin

30
Q

psychodynamic view of treatments of unipolar depression

A
  • psychodynamic therapy: seeking unconscious causes and using psychodynamic procedures to work through them - not supported
31
Q

cognitive behavioral view of treatments of unipolar depression

A
  • cognitive behavioral therapy: behavioral activation, recognize and change negative cognitive processes
32
Q

sociocultural view of treatments of unipolar depression

A

family social perspective:
- interpersonal psychotherapy (IPT): identify and resolve four types of problems that can lead to depression; loss, role dispute, role transition and deficits
- couple therapy: solving depression related to malfunctioning relationships by improving communication and problem-solving skills
multi-cultural perspective:
- helping someone recognize the consequences of their culture on their mental state and combining that with other sorts of treatment

33
Q

bipolar disorder

A

disorder marked by alternating or intermixing periods of mania and depression. two types in DSM-5:
- bipolar diorder I
- bipolar disorder II
- cyclothymic disorder

34
Q

bipolar disorder I

A

alternation between full manic and major depressive episodes
- full manic episode: high or irritable mood and heightened energy or activity for. most of every day for at least 1 week, and experiencing at least three of the following symptoms: grandiosity or overblown self-esteem, reduced sleep need, increased talkativeness, thoughts moving very fast, attention pulled in many direction, heightened activity, excessive pursuit of risky activities

35
Q

bipolar disorder II

A

alternation between hypomanic episodes (very mild manic episode) and major depressive episodes

36
Q

cyclothymic disorder

A

alternation between hypomanic and mild depressive symptoms, may evolve into bipolar I or bipolar II

37
Q

biological view of causes of bipolar disorder

A
  • neurotransmitters: higher norepinephrine and lower serotonin
  • ion activity: irregularities in transport
  • brain structures: les gray matter, small cerebellum and basal ganglia
  • genetic factors: genetic predisposition to develop disorder
38
Q

treatments for bipolar disorder

A
  • mood stabilizing (anitbipolar) drugs: lithium (affects neurons’s second messengers, and may alter ion activity)
  • adjunctive psychotherapy
  • psychotherapy or mood stabilizing alone is rarely helpful, so they combine them
39
Q

parasuicide

A

a suicide attempt does not result in death

40
