Environmental risk factors and medical conditions associated with Bipolar disorder In addition to the genes implicated in Bipolar disorder, a number of environmental risk factors including famine and viral infection have been decribed. These are listed in this table with reference links to Wikipedia and Pubmed.Ongoing clinical trails, worldwide, can be interrogated at ClinicalTrials.Gov a service of the US National Institutes of Health

Prenatal and perinatal

  • Maternal Famine as a risk factor for offspring Brown et al, 2000
  • Low birthweight for pre-term births can be a risk factor in later life Laursen et al, 2007
  • Diverse perinatal risk factors (drugs and birth complications) can increase the risk of pediatric bipolar disorderPavuluri et al, 2006
  • Prenatal infection during the first trimester (Influenza or common cold) have been associated with subsequent cycloid psychosis in the offspring Stober et al, 1997
  • A significant, increase in the risk of Bipolar disorder in the offspring after exposure to maternal influenza at any time during pregnancy (odds ratio = 3.82) Parboosing et al, 2013.
  • An excess of winter/spring births has been observed for Bipolar disorder and schizophrenia Torrey et al, 1997
  • Maternal stress during the first trimester (Arab-Israeli War) associated with an increased risk of bipolar disorder and other affective disorders in the offspring Kleinhaus et al, 2013

Comorbidities

  • Individuals with OCD spectrum disorders may be vulnerable to bipolarity D'Ambrosio et al, 2010
  • Comorbidity with borderline personality disorders Marcinko and Vuksan-Cusa, 2010
  • Comorbidity with attention deficit in children Castilla-Puentes, 2008
  • Patients with bipolar disorder may die prematurely from multiple causes, including cardiovascular disease, diabetes, COPD, influenza or pneumonia, unintentional injuries, and suicide. However, chronic disease mortality among those with early diagnosis approached that of the general population, suggesting that better provision of primary medical care may reduce premature mortality (National cohort study of 6,587,036 Swedish adults, including 6618 with bipolar disorder) Crump et al, 2013
