What is the mechanism of action of SSRIs (Selective Serotonin Reuptake Inhibitors)?

Step 1: Understand that serotonin is a chemical in the brain that helps regulate mood.
Step 2: Know that neurons (brain cells) communicate with each other using chemicals like serotonin.
Step 3: When a neuron sends serotonin to another neuron, some of it is taken back (reuptake) into the first neuron.
Step 4: SSRIs are medications that block this reuptake process.
Step 5: By blocking reuptake, SSRIs allow more serotonin to stay in the space between neurons (called the synaptic cleft).
Step 6: More serotonin in the synaptic cleft means that the receiving neuron can use more serotonin, which can help improve mood.
