Results of a new study published in JAMA Psychiatry last week showed that prenatal exposure to influenza is linked to a nearly fourfold increase in the risk of bipolar disorder, according to MedPage Today.
The results were pulled from medical records from a sample of pregnant women who received prenatal care in Northern California from 1959 to 1966. Previously, this sample set also revealed a link between prenatal exposure to influenza and schizophrenia. The data was analyzed again and the link to bipolar disorder was revealed.
According to MedPage Today, “the researchers found that offspring exposed to influenza infection in the womb were nearly four times more likely to develop bipolar disorder overall, while exposure in the third trimester was associated with a nearly five-fold increase in risk”.
The researchers note that replication is required, but these results suggest that preventing maternal exposure to the flu could potentially reduce the risk of bipolar disorder in offspring.
