5+ symptoms
2 week period

Etiology depression
Combination of biological, social, psychological
BIological factors
Behaviour genetics
Biochemical
Brain abnomalities
Biochemical
Neurotransmitters
Hormones
Neurotransmitters
Communicate b/w neurons (absent = depression)
Norepinephrine - energy, motor activity
Serotonin - memory, concentration
Dopamine - rewarding stimuli
Hormones
HPA axis
Cortisol
Brain abnormalities
Profronal cortex
Emotion regulation system
Left frontal hemisphere asymmetry - right more activated = more depressed
Emotion regulation system
Amygdala - emotional importance Emotion regulation Subgenual anterior cingulate Dorsolateral prefrontal cortex Hippocampus
Social/ environmental factors
Life stress
Biological vulnerability and stress reactivity
Diathesis-stress model
Mental health disorders due to predisposition and stress
Cognitive theories
Negative thoughts & beliefs = depression
Cognitive distortiosn
Should-ing Over-generalisation Discount positives Black and white thinking Unfair comparisons
Beck’s cognitive therapy
4 phases (~20 sessions) 1 elevate mood 2 challenge antomatic thoughts 3 identity negative thinking 4 change primary attitude
Cognitive restructuring
Effective and reduced relapse
Online and face to face
Antidepressant drugs
MAO inhibitors
Tricyclics
Selective serotonin reuptake inhibitors
Electroconvulsive therapy
For severe depression
Side effect - damaging
relapse common
