A new study indicates that, as we age, our thyroid activity may put us at an increased risk for depression. Research shows that even minor changes in thyroid levels can have an effect on our mental health. The researchers analyzed data of more than 1500 people with an average age of 70. Each had their thyroid tested and was depression free at the beginning of the study. After eight years of follow-up, the results show that, even with levels in the normal range, change in thyroid activity is linked to an increased risk of depression symptoms for retirees.
The thyroid is one of the largest endocrine glands in the body and is found in the neck. This gland produces hormones that control most of our metabolic processes such as how quickly our body uses energy.
