Glandular fever associated with greater risk of depression New research shows that patients who have had contact with the hospital due to serious glandular disease have a greater risk of subsequently developing depression. The study from iPSYCH is the largest yet to show a correlation between glandular fever and depression. The vast majority of Danes have had glandular fever - also called mononucleosis - before adulthood. And for the vast majority of them, the disease can be cured at home with throat lozenges and a little extra care. But for some, the disease is so serious that they need to visit the hospital.
