The video helps you to under anti-depressants and explains the mechanism of action of SSRIs (Selective Serotonin Reuptake Inhibitors) and why they take time to show therapeutic effects by reviewing how SSRIs in the brain work. SSRIs block the serotonin transporter protein (SERT) in neurons, allowing serotonin to remain in the synapse longer, but this doesn't expalin Why Anti-depressants take so long to work. Initially, there's an increase in serotonin in the somatodendritic region, causing immediate side effects. This increase stimulates pre-synaptic 5-HT1A autoreceptors, triggering a negative feedback loop that downregulates these receptors over time. With decreased autoreceptor activity, serotonin release from axon terminals increases, leading to therapeutic effects in depression. The delayed onset of these effects is due to the time needed for downregulation and subsequent disinhibition of serotonin release. The video stresses that while the neurochemical model helps understand SSRIs' action, it's simplistic and not fully explanatory. It challenges the notion that SSRIs directly correct serotonin deficits, suggesting instead that they induce changes in the brain that eventually alleviate depression symptoms. These changes likely involve alterations in gene expression and protein synthesis. The video encourages humility in interpreting these models and acknowledges the complex interplay of neurochemistry, cognition, and psychology in understanding depression and its treatment.
