Depressed people out of sync with others, says study

According to a new study, people suffering from depression have 'broken body clocks'.

The research, which was carried out by scientists at the University of Michigan Medical School in the US, found that depressed people are out of sync with the rest of the population. This could explain a link between the condition and changes in the circadian rhythm. It is thought that the discovery could provide more insight in how to treat the condition.

The study was carried out using donated brains from both depressed and non-depressed people. Lead author of the study, Jun Li, Ph.D (an assistant professor), described the research as a 'real moment of discovery', according to

She added: "It was when we realized that many of the genes that show 24-hour cycles in the normal individuals were well-known circadian rhythm genes and when we saw that people with depression were not synchronized to the usual solar day in terms of this gene activity. It's as if they were living in a different time zone than the one they died in."

According to, one in 20 people in the UK will suffer with depression at some point in their life. Those who feel like they are experiencing symptoms such as continues low mood or sadness, lethargy and hopelessness may want to visit their GP - who might recommend treatment such as anti-depressants or counselling courses.

The findings are published in the Proceedings of the National Academy of Sciences.
