What did Kirsch find about antidepressants and the placebo effect
- using SSRIs for the treatment of MDD… 50% was genuine placebo effect
- Analysis of all available data suggests placebo effect accounts for 80% of patient response
- drug manufacturers bury negative findings and bias…
- insufficient evidence in favour of prescribing SSRIs
- recommend psychotherapy, exercise, acupuncture for same benefit with lower risk of side effects
- relapse rates higher in ADMs than other treatments
What does Iatrogenic mean?
they cause side effects that could lead to disease
What is the continuation phase?
the period of time between when meds would be effective and the depressive episode would have resolved on its own -> suggesting “better” to stay on meds
