State some environmental risk factors for depression

Describe the change in depression incidence in males and females through puberty

Before puberty, incidence is the same in males and females. Between ages 11-13, incidence dramatically increases in females but only increases slightly in males. By 15, females are twice as likely to experience a major depressive episode


Give some potential explanations for the gender differences in depression incidence in adolescence

Hormones (testosterone affects social and affective information), rapid growth (change in body shape), circadian rhythm changes


Describe the changes in the prefrontal cortex during adolescence

Grey matter thinning, synaptic pruning, myelination


Describe the influence of the amygdala and prefrontal cortex on depression

Increased amygdala to prefrontal cortex connectivity is associated with an increase in adolescent suicidal ideation and attempts (Alarcon etal, 2019) - but positive parenting is protective, associated with decreased amygdala growth and increased cortical thinning (Whittle et al, 2013)


Describe the cognitive changes which occur during adolescence

Thoughts become more logical with more abstract reasoning

4) Self-harm more common


Give 3 mental health disorders associated with adolescent depression

Psychological therapy - either CBT, interpersonal psychotherapy, or psychodynamic psychotherapy


What is the most commonly prescribed SSRI for adolescent depression?



What percentage of deaths are due to suicide?



Give 3 directions of research for adolescent depression

Exercise as therapy, treatment for neuroinflammation, therapies for the gut microbiome, pharmacogenetics, internet-based therapies
