Teenagers suffering from depression may have abnormal brain structure, according to new research. An article published in BMC Medicine this week shows that adolescents diagnosed with major depressive disorder tend to have a small hippocampus--a part of the brain associated with motivation, emotion, and memory formation. Optimizing the diet is clearly an important step in dealing with depression, and one of the most important tools will be to make sure you are getting enough omega-3 fats like those in fish oil and cod liver oil.
