One in three people with a strong family history of bipolar disorder (manic depression) are reluctant to have children due to the hereditary nature of the illness and its perceived social stigma, new research from the University of New South Wales (UNSW) has found.
The findings, to be published this month in the journal Psychological Medicine, suggest the negative attitude to childbearing is significantly more pronounced with bipolar disorder than with other hereditary diseases such as Huntington disease or hereditary cancer - even when the genetic risks are lower.
Researchers from UNSW’s Faculty of Medicine surveyed 200 people with a strong family history of bipolar disorder, including 105 with the illness, and found that more than a third (35 percent) was either unwilling or less willing to have children. That number rose to 50 percent among those diagnosed with the condition.
Lead author of the study, Associate Professor Bettina Meiser, from the School of Psychiatry at UNSW and the Psychosocial Research Group at Sydney’s Prince of Wales Hospital, says the attitude was pronounced.
“The proportion of people less willing or unwilling to have children is not in line with other genetic disorders,” Professor Meiser says.
“We know from studies into childbearing among people at high risk of cancer, for example, where the lifetime risk for a gene mutation carrier can be 80 per cent or more, that attitudes to child bearing are not affected in any significant way. Even having a very serious disorder, such as Huntington disease, doesn’t deter that many people from having children.
“Our research shows that what makes bipolar disorder unique is the stigma.
