More evidence that your mom's illnesses can affect your mental health

You've probably heard before that people with schizophrenia are more likely to have been born in winter than other seasons — and that this weird fact could be linked to their mothers coming down with the flu, or suffering from Vitamin D deficiency. A new study has now found that people with bipolar disorder had a greater likelihood of being born to women who had had the flu while pregnant. It's a strange connection, and might just be correlation. So far, doctor's don't really understand why a virus-infected mama would lead to her child developing mental illness later in life.
