Q

Biological explanation- genetics

A

Family history doubles the likelihood of the development of mood disorders.

Thought to be the result of multi gene action.

Q

What is mcguffins study?

A

Bipolar- investigated the genetic predisposition idea.

Looked at twin studies and Compared them. MZ- 46% and DZ- 20%

Shows genetic influence

17
Q

What do noradrenaline and serotonin do?

A

Found in the limbic system of people with depression. Affects sleep/appetite and emotions. And imbalance, too low causes depression, too high- mania

18
Q

What was shastrys study?

A

Found that during a manic episode, serotonin levels are low and noradrenaline levels are high. During a depressive episode, both are low

19
Q

What was teutings study?

A

Tested the samples of urine in those with depression. Tested the levels of a compound which is present after neurodrenaline and serotonin are broken down. Those with depression had lower levels of the compound suggesting lower than normal levels in the brain

20
Q

What hormone is high in the blood of those with depression?

A

Cortisol- usually present in stressful situations however was still high in those with depression even after the stressful event had passed

21
Q

What areas are affected by depression? (Brain abnormalities)

A

What prefrontal cortex
Amygdala
Hippocampus

22
Q

Evaluation of the biological explanation for mood disorders

A

❌unclear whether brain abnormalities are a cause of effect
❌ teutings study- low levels could be the effect of mood disorders rather than the fair
❌not 100% concordance in twin studies- environmental input
❌ no single gene detected
❌ deterministic- saying people have a brain defect etc could prevent recovery as people lose hope

23
Q

What does the cognitive explanation say causes depression?

A

People become depressed as they think in negative and self- defeating ways

24
Q

what are the 4 ways of thinking with depression that beck proposed?

A

Overgeneralisation- one negative event means everything is negative

Magnification- blowing things out of proportion

Select perception- perceiving only bad events

Absolute thinking- everything has the be perfect otherwise it’s a disaster

25
Becks negative schema study
Investigated the schemes used by people with depression. Used the DAS scale, dysfunctional attitude scale. He used a control group and a group of students diagnosed with depression. He found that those with depression scored more highly, showing their negative thought process
26
Evaluation of becks DAS scale study
❌ negative schemas could be the cause not the effect of depression
27
Becks cognitive triad of constant negative thought
Self- not good enough for anything World- the world is a horrible place Future- there is nothing in the future for me
28
Evaluation of the cognitive explanation for mood disorders
✅ cognitive triad led to the most successful treatment ever ✅ based on sound scientific research ❌ negative schemas- cause of effect?? ❌ doesn't explain the mania phase of bipolar
29
What is the psychodynamic approach to depression?
Freud based his Thoeru of depression on loss and dependency. How a child deals with loss in childhood effects them in adulthood with how they deal with things
30
What is the introjection of hostility Theory? (Psychodynamic)
Grief in childhood leads to rejection. The ego becomes self-centred and believed this is somethings he/she has done. They turn to self blame and punishment. If they don't deal with this as a child, when they encounter loss as an adult they will regress to the oral stage (high dependency)
31
Bowlby's attachment theory- depression
If there isn't a strong attachment with a mother figure during childhood then depression could occur later in life as a result
32
What happened to the personality which causes mania in bipolar? (ID,Ego, superego)
- during the depressive stage the superego dominates the ego and causes the person to feel guilty- resulting in depression - the ego tries to assert itself but overreacts and causes the individual to enter the mania phase This is repeated-
33
Evaluation of psychodynamic explanation for depression
✅ early theories of Freud lead to the development of an interpersonal theory of depression which is an effective treatment ✅ there is support for bowlbys theory ❌largely unscientific- cannot prove early childhood experiences effect us etc ❌ depressed people often express anger towards others which isn't supported by the introjection hostility theory
34
What are the biological treatments for depression?
Antidepressants- Monoanime oxidase inhibitors Selective serotonin reuptake inhibitors Electro convulsive shock therapy Lithium carbonate- bipolar depression
35
Evaluation of biological treatments
❌ antidepressants take time to work, patients often don't wait and stop taking them ❌ if they aren't taken symptoms re-occur- suicide ❌ don't deal with the cause of depression ❌ not everyone responds ✅ drugs work well when combined with cognitive therapy etc ✅ effective in 75% of cases
36
What are the cognitive treatments for depression?
Becks cognitive triad therapy Rational emotive therapy- hollon
37
What is becks cognitive triad therapy?
Challenging the negative schemas The cognitive triad of negative thought is changed in 4 phases 1- confidence is increased 2- automatic negative thoughts are challenged 3- negative thoughts are identified 4- key attitudes and beliefs are changed
38
What is rational emotive therapy?
Irrational thoughts are replaced with rational thoughts to show the patients how their thinking is damaging. For example the negative belief- 'I need to be perfect in everything I do...' Would be changed to ' I can try my best but I am not always going to be the best every time'
39
What was hollons study? Treatments KEY STUDY ‼️‼️
compared the effectiveness of cognitive therapy and drug therapy in depression. He used patients with moderate- severe depression either one of the treatments. Relapse rates for cognitive was 40% Relapse rates for drugs was 45% Placebo relapse rates- 80% Shows that cognitive therapy is as effective as drugs
40
Evaluation of cognitive therapy treatment
✅ highly effective- relapse rates are 60-70% after 10-12 weeks of treatment ✅ can be used 1-1 or in groups- cost effective ✅ combination of this and drug therapy is often the most effective ❌ doesn't work for everyone- they have to be articulate and motivated ❌ less useful for treatment of mania in bipolar
