Dr. Marylynn Wei writes, “One traditional hypothesis of depression is that people who are depressed have a deficiency in monoamine neurotransmitters in the body, which leads to low levels of neurotransmitters like serotonin and norepinephrine in the brain.

Brain imaging of people with depression show that their brain scans have increased neuroinflammation. When your body is in an inflammatory state fighting off the common cold or flu, you can experience symptoms overlapping with depression— disrupted sleep, depressed mood, fatigue, foggy-headedness, and impaired concentration.” Read the rest of her blog.
