Disruption of the gene controlling the circadian rhythm could affect individuals with depression

A study from Ohio State University found that changes in gene activity that controls the circadian rhythm are linked to the development of depression, reports physorg.com.

Researchers told the news source that teens who suffer from depression have higher levels of activity in the gene that controls the body’s 24-hour biological clock and behavioral cycle. They added that sleeping patterns and other physiological functions controlled by the circadian rhythm are influenced by increased activity of this gene.

However, they warn that the relationship shows no causal effect and is being classified as only a link. Furthermore, researchers are unsure whether other biological or environmental influences could collaborate to disrupt the circadian clock.

Individuals who suffer from depression often experience common symptoms such as restlessness, irritability, decreased energy and insomnia from the lack of serotonin production in their body.

According to the National Institute of Mental Health, nearly 15 million people in the U.S. suffer from depression.
