Is depression caused by an inflamed brain? A review of studies looking at inflammation and depression has found that a class of anti-inflammatory drugs can ease the condition’s symptoms.
Fatigue link?
The most commonly used anti-depressant drugs, known as SSRIs, act to increase levels of serotonin in the brain, to improve a person’s mood. But depression might not always be linked to a lack of serotonin, and SSRIs don’t work for everyone.
Recent research has found that around a third of people with depression appear to have higher levels of cytokines in their brains, while people with “overactive” immune systems seem more likely to develop depression. Khandaker’s team think that inflammation in the brain might be responsible for the fatigue experienced by people with depression.
