Washington D.C: It might sound a bit strange but even a single hair from those lush locks could help in diagnosing depression. A new study examined the cortisol (steroid hormone released by the adrenal glands) levels in the hair of teens in order to monitor the effects of treatment. Researchers looked for potential relationships between the concentration of the stress hormone cortisol in the hair and adolescents’ depression symptoms and found a surprising connection.
Not only did high cortisol levels correspond to a higher likelihood of depression, but there was also a connection between low cortisol levels and mental health struggles.
“This study opens up a lot of future research questions and illustrates that the relationship between cortisol levels and depression isn’t necessarily a linear one,” said Jodi Ford, the lead study author. “It may be that low cortisol is bad and high cortisol is bad and there’s a middle level that is normal,” she added. Another important finding from the study was that adolescents who said they felt better supported at home had much lower levels of depressive symptoms. “This study reinforces to parents that they matter in their adolescents’ lives that their support and involvement make a difference,” said Ford. For the study published in the journal ‘Psychoneuroendocrinology’, researchers incorporated 432 adolescents between the age of 11-17 years.
