Researchers have found a connection between migraine headaches and depression. The research supports the idea that depression and migraines share related biological factors, possibly hormonal or with brain chemicals. The evidence was based on a recent study of 496 adults with a history of migraines, 151 individuals with severe headaches, and 539 people without headache problems. During the 2-year study conducted by the Henry Ford Health System, people with migraines were 5 times more likely than headache-free individuals to develop major depression. Those with depression at the beginning of the study were 3 times more likely to develop migraines.
One study linked multiple pregnancies to an increased risk of developing atrial fibrillation later in life, and another investigated the association between premature delivery and cardiovascular disease.
