🧠 Addiction Psychiatry: The Power of Salience 🚀 🧵

The study on escitalopram v placebo in healthy volunteers measuring reinforcement sensitivity has caused a stir as usual with incorrect interpretations of ‘SSRIs blunt emotions’This is incorrect - let us understand reinforcement sensitivity 🧵👇
Keeping it simple -Humans utilise the limbic network (Amygdala-Ventral striatum) & PFC to respond to stimuli & make decisions leading to actions. Reinforcement learning / reward learning helps us solve problems. Reward does not only mean pleasure. Removal of a ‘problem’ =reward

With 1-way ideologies (the chemical imbalance) I find one rule useful. As Taleb says (finance) don't ask a person what their opinion or reco is - ask them what's in their portfolio. So @markhoro@joannamoncrieff@HengartnerMP-how do you treat depression? Do u prescribe SSRIs? 1/n
Do you prescribe antidepressants that directly or indirectly act on serotonin receptors. If you prescribe ADs how do you explain this to the patient. @markhoro you in detail explain withdrawal Sx neurobio- how do you Rx dep in your practice? 2/n
