Higher IQ in Children Causes Bipolar Disorder: New Study

All parents want their little ones to be super-brainy, cracking the crosswords like no one could and finding solutions of problems that no one can think of, in short being smart and intelligent. However, every good thing comes with a flaw, and having higher IQ also has one major one.

A new study by British and American scientists have shown that children who have greater IQ have the possibility of having severe mood conditions like bipolar disorder.

For the research, scientists analyzed the records of a birth legion known as the “Avon Longitudinal Study of Parents and Children (ALSPAC) that constituted of over 14,000 women, their companions and children, and tracked for more than twenty years to achieve information of several phases of life.

The research team searched for a connection between calculations of childhood IQ – both verbal IQ (VIQ) and performance IQ (PIQ) at eight years of age and lifetime agitated traits – the Full-Scale IQ (FIQ), gauged at 22-23 years of age.

Of the whole legion, the final outcomes of 1, 881 participants indicated a positive connection between childhood IQ and adulthood agitated traits.

In fact, those who had an average childhood IQ scored 10 percent of the agitated traits, which was nearly 10 points more than the individuals who scored the least of the 10 percent of agitated traits. Nonetheless, agitated traits showed the strongest connection with verbal IQ (VIQ).

However, Daniel Smith, who is a professor of University of Glasgow, and leader of the study emphasized although greater childhood IQ is a “clear-cut risk” for bipolar disorder, the “shared biology” between these two “needs to be understood more fully”.

He further said that a family history of mental conditions, childhood problems, agitated life events and drug misuse are some other reasons why one may show signs of bipolar disorder.

He added that their study will help “future genetic studies” regarding bipolar disorder, intelligence and creativity to develop as well as endeavors to enhance methods to detect bipolar disorders as early as possible in adults.

Chief Executive of Bipolar UK, Suzanne Hudson said that considering the increase in requests for supporting parents and families of children, admitted to their institute; any study that caters to “identify people more at risk of developing bipolar disorder is vitally important”.

The study has been published in the “British Journal of Psychiatry”.

Bipolar disorder also known as “bipolar affective disorder” and “manic-depressive illness” is a condition where an individual experiences transition of moods – from mania to depression, in frequent successions.

The episodes can last from days to weeks to even years.

The symptoms can range from feelings of guilt, isolation, trouble in sleeping, appetite alterations or even suicidal thoughts.

As reported by Treat Depression, smart and intelligent people in their quest to find the deeper meaning of life and the “chaotic word” become sad. It further said that these kinds of people tend to spend prolonged periods of time secluded with their thoughts, leading them to become socially isolated from average individuals.

It added that due to their smartness, average people tend to not understand them and term them boring. And this is what makes the intelligent people depressed.

Another research conducted by scientists at King’s College London and Karolinska Institute in Sweden discovered that those individuals who achieved A grades in school indicated to have four times more possibility of bipolar disorder than other adults.

James MacCabe, who led this study said, “These findings provide support for the hypothesis that exceptionally intellectual ability is associated with bipolar disorder.”

A Finnish study led by Jari Tiihonen, associated with University of Kuopio in Finland also showed connection between high grade achievers and bipolar disorders, albeit through arithmetic methods.

The research team analyzed the records on Finnish military drafts, and discovered a 12-fold elevated association between high-scorers and those who developed bipolar disorders later in their lives.

Actor-comedian Russell Brand, actress Catherine Zeta-Jones and comedian Stephen Fry are some of the famous names who suffer from bipolar disorder.

According to the National Institute of Mental Health, 5.7 million of adults in America suffer from bipolar disorder, which is 2.6 percent of the U.S population.
