The collaborative study, conducted by the University of Rochester School of Medicine and Dentistry and the School of Nursing, found that people with lower cognitive ability were more likely to have higher depressive symptoms if they also had low levels of IGF-1. Reversely, participants with high levels of IGF-1 had no link between depressive symptoms and memory.
