According to Robert Preidt writing in the Long Island Newsday, research published on 1st Oct in the American Journal of Psychiatry has demonstrated an association between exposure to tobacco smoke in the womb and bipolar disorder development in later life.
According to Preidt, ‘researchers looked at 79 people with bipolar disorder and 654 people without the condition who were born between 1959 and 1966. People born to mothers who smoked during pregnancy had a twofold increased risk of developing bipolar disorder’.
Much more research is required in order to investigate this association further and to uncover underlying mechanisms.
