USA Today (7/31, Molina) reports that “people with depression” appear to have “low levels of acetyl-L-carnitine [LAC], which helps the body produce energy,” researchers say. The findings were published online July 30 in the journal Proceedings of the National Academy of Sciences.Newsweek (7/31, Gander) reports that investigators arrived at the study’s findings after testing “blood samples from 116 participants, 71 with depression and 45 without.” The study also found that “patients with very low LAC levels were more likely to have more serious depressive symptoms and to have developed depression earlier in life.” Additionally, there was “a higher chance they had experienced childhood trauma and were resistant to treatments for depression.” The Philadelphia (PA) Inquirer (7/31, Haydon) also covers the story.
