Analysis finds that people in their early 20s who had high levels of manic features had greater IQ at age 8 than those with low levels.

New research published today in the British Journal of Psychiatry suggests that serious disorders of mood such as bipolar disorder may be the price that human beings have had to pay for more adaptive traits such as intelligence, creativity and verbal proficiency.

Scientists at the Universities of Glasgow, Bristol, Cardiff and Texas looked at data from the ‘Children of the 90s’ birth cohort, officially called the Avon Longitudinal Study of Parents and Children (ALSPAC), and found that higher childhood IQ could indicate greater risk of bipolar disorder in adulthood.

ALSPAC contains information on more than 14,000 women, their partners and offspring, which has been followed up over two decades to give insights into various aspects of health.
