eli5: Why do antidepressant takes 2-4 weeks to work when brain changes happen right after the first dose?
In: Biology
Basically, imagine a riverbed moving. A river does not form a new riverbed in an instant.
It takes time for the new paths/lines of thought to form before the effects are fully felt.
The first impact is the energy level, but the frame of reference that is used to ensure antidepressants work, is your own analysis of your thoughts. It helps you change them but your brain has to do the changes itself.
