An off-kilter body clock can throw off our sleep-wake cycle, eating habits, body temperature and hormones–and mounting evidence suggests a malfunctioning clock may also underlie the mood cycles in bipolar disorder.
In a new study led by psychiatrist Alexander Niculescu of Indiana University, researchers found that children with bipolar disorder were likely to have a mutated RORB gene, which codes for a protein crucial to circadian clock function. The team’s previous work identified alterations to this gene and other clock genes in animal models of the disorder. In the new study, the scientists compared the genomes of 152 bipolar kids with those of 140 typical kids. (Children were studied because their moods cycle more rapidly than the moods of bipolar adults, and a quicker cycle suggests a stronger connection to the circadian clock.) The team found that the bipolar children were more likely to have one of four alterations to RORB , and the investigators suspect the mutations prevent the body from producing the correct amount of the protein to support normal clock function.

The connection between Circadian Rhythm and Bipolar Disorder is not new. Circadian Rhythm or “internal body clock” has been connected to Bipolar Disorder for many years, and several treatments like social Rhythm therapy are employed to help regulate the Circadian Rhythm or 24 hours internal body clock.
