How do genetic theories explain major depression ?
- 1st degree relatives 2 to 3 times more likely
- Moderate heritability (30-40%)
- Stronger genetic base for early onset depression
- Serotonin transporter gene
How do neurotransmitter dysfunction explain major depression ?
- Monoamine neurotransmitters: norepinephrine, serotonin, dopamine in limbic system have been associated with depression -> low
How do brain abnorbilities explain major depression ?
- PFC: reduced activity & grey matter (esp. left side which is particularly involved in goal-orientation)
- Anterior cingulate: overactivity
- Hippocampus: smaller volume & lower activity
- Amygdala: large & increased activity
- Many receptors for cortisol which is chronically adjusted !
How does the Hypothalamic-Pituitary-Adrenal explain depression ?
- HPA
Step 1: hypothalamus releases CRH (corticotropin-releasing hormone) onto receptors of anterior pituitary
Step 2 AP: releases corticotropin into bloodstream which stimulates adrenal cortex
Step 3 AC releases cortisol into bloodstream which helps body fight the stressor or flee from it
Steo 4: hypothalamus has cortisol receptors that detect the increased levels & decreases CRH
-> but the hippocampus does not work properly by depressed people
and u also have and increased pituitary gland which leads to increase in cortisol !!
-> More a trait then state !
How do behavioural theories expalin major depression ?
- +/- 80% of depression cases report a negative life event prior to the onset
- Life stress leads to depression because it reduces the positive reinforcers
- Pattern esp. likely for people with poor social skills
What is meant by the learned helpessness theory ?
- an uncontrollable neagtive event is most likely to lead to depression
- This leads people to think that the sitch isn’t controllable (which is wrong)
- > explains abused partnership

People have:
- Negative cognitive triad/self schema (Beck)
- Hopelessness depression
- Ruminative response style theory
What is meant by Reformulated learned helplessness theory ?

What is meant by negative cognitive self schema ?
- people have negative views of themselves
What is meant by Hoplessness depression ?
- people make pessimistic attributions for the most important events in their lives & think they have no way of coping with the consequences
What is meant by ruminative response style theory ?
- focus on how they feel and , identify many possible causes without doing anything about them & continue to ruminate about their depression
What are the 4 biases regarding major depression ?
- biased attention (can not disengange of them)
- negative interpretation bias
- memory bias (enhanced memory for negative relative to positive information)
- cognitive control bias (can’t inhbit negative material from entering WM & cant remove previous negative material)
How do the interpersonal theories explain major depression ?
- Chronic conflict in their relationships
- Heightened need for approval & expression of support from others
- Rejection sensitivity
What are some cultural differences regarding depression ?
- More recent generations at higher risk
- desintegration of family and high expectations of self
- Men compensate with alc and woman with rummination
- Cultures with more poverty(por), unemployment & discrimination have higher rates

- 3 or more syptoms present
- impair social functioning / or hospitalization
- not to substance abuse
What is the defintion of bipolar disorder ?
- characterized by changes from manic episodes to depressive episodes
What is meant by manic disorder ?
- above average regarding enthusiasm mood and general activity
What are the symptoms of the DSM 5 of bipolar dissorder ?

- decreased sleep
- more talkative
- Flight of ideas
- Distractibility
- Increase in goal-directed activity
- active involvment in painful activites
What are the criterias for bipolar 1
All of the symptoms of mania are present and can be preceded or followed up by hypomania and depressive episode (but are not necessary)
What are the criterias for bipolar 2

How do gentic factor explain bipolar disorder ?
- First degree relatives 5-10x higher rates
- highly inherited
How do brain abnormalities explain bipolar disorder ?
- Amygdala & PFC same as depression but not hippocampus
- Basal ganglia: hypersensitivity to rewarding cues in environment
- Striatum -> Dysregulation of dopamine system
- PFC-basal ganglia-amygdala circuit
- White matter abnormalities: bad communication between PFC & other areas
What are the two phases regarding the straitum function in bipolar disorder ?
- Manic phase: : inflexibly & excessively seek reward
- Depressive phase:highly insensitive to reward
How does the psychsocial tehory explain bipolar disorder ?
- > greater sensitvity to reward = mania
- greater sensitvity to punishment = Depression

- Bad drugs with dangerous side effect : Tricyclic antidepressants and MAO-inhibitors (breakdown of the monoamine neurotransmitters )
What are some drugs which help bipolar dissorder (mania disorder)
- Lithium
- Atypical antipsychotic medications
Explain the effects of Lithium:
- reducing suicide risk
- too much = toxic
- Improving functioning of the intracellular processes
Explain the effects of Atypical antipsychotic medications:
- reduce functional levels of dopamine (in amygdala)
- more for mania
What other major treatment options exist regarding bipolar disorder ?
- Electroconvulsive Therapy
- Brain Stimulation
- Light Therapy
Explain how electroconvulsive therapy works:
- passing electrical current through the patient’s head
- Decreases metabolic activity in several regions of the brain, incl. PFC & anterior cingulate
- Mostly right side
Explain how brain stimulation works on bipolar patients: (3 forms)
- Repeated rTMS session: on left PFC cause low metabolic activity
- Vagus nerve stimulation (VNS): increases activity in hypothalamus & amygdala
- deep brain stimulation ( electrodes are implanted)
For which particular disorer is light thearpy working out ?
- SAD
- Exposure to light in combination with cognitive therapy
