Real Life Examples of Monoamine Imbalances and Depression

🧠 Quick Study Guide

• 🧬 Monoamines are neurotransmitters like serotonin, norepinephrine, and dopamine.
• 📉 Imbalances in these neurotransmitters are linked to depression.
• 💊 Selective Serotonin Reuptake Inhibitors (SSRIs) are common antidepressants that increase serotonin levels.
• ⚡️ Norepinephrine and dopamine affect energy, focus, and motivation.
• 🧪 Depression is a complex condition influenced by genetics, environment, and individual biology.
