Tick tock: Study links body clock to mood disorders
The study cannot say conclusively that body clock disturbances are what caused the mental risk, instead of the other way round. But the findings “reinforce the idea that mood disorders are associated with disturbed circadian rhythms,” said Lyall. “Seventy-five percent of [mental] disorders start before the age of 24 years,” said University of Oxford researcher Aiden Doherty, commenting on the paper. “The circadian system undergoes developmental changes during adolescence, which is also a common time for the onset of mood disorders,” he added. Last year, the Nobel Prize for medicine was awarded to three US scientists who pioneered our understanding of how the circadian clock ticks.
