How SSRIs Actually Rewire Your Brain (and What Happens When You Stop)

Antidepressants like SSRIs and Strattera don't just fix a "chemical imbalance" — they trigger a months-long process of structural brain remodeling, from new dendritic spines to adult neurogenesis. This episode breaks down the molecular cascade from serotonin to BDNF to new neural growth, the three major brain networks that physically change during treatment, and the uncomfortable asymmetry: it takes weeks to build new connections but only days for them to retract after withdrawal. We explore what that means for relapse rates, informed consent, and whether the positive changes can ever last.
