Bipolarity or depression: a blood test promises to make a difference. More than 40% of people with bipolarity are initially diagnosed with depression.

This is why it takes on average between eight and ten years before the correct diagnosis is made. The treatments are indeed different and some of them, incorrectly prescribed during bipolar depression, can even worsen the pathology. For several years, researchers have been working on a test to identify those who are at risk of developing bipolar disorder. The test, available since Monday, raises reservations among many psychiatrists.
