A link between high IQ and bipolar disorder has been postulated for a number of years, but the scientific evidence has so far been lacking. However, relatively recent research published in the prestigious British Journal of Psychiatry, has provided strong evidence for a link between intelligence and bipolar disorder.
Researchers at the Institute of Psychiatry, King’s College London and the Karolinska Institute in Sweden, accessed information from the Swedish national school register on all 713,876 students graduating from secondary school between 1988 and 1997. This information was cross-referenced with figures from the Swedish hospital discharge register on diagnosis of bipolar disorder between the ages of 17 and 31.
Interestingly, the British and Swedish research teams found that among boys, excellent school performance was linked to almost four times the average risk of developing bipolar disorder.
