Alzheimer's Disease in Men Linked to Low Levels of Hormone, IGF-1, Broca Hospital Study
Published: Oct 02, 2012
Low serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) are associated with Alzheimer's Disease in men, but not women, according to a recent study accepted for publication in The Endocrine Society's Journal of Clinical Endocrinology & Metabolism (JCEM). IGF-1 and IGFBP-3 are involved in longevity and could be beneficial to cognition, especially in Alzheimer's disease where experimental studies have shown that IGF-1 opposes the main pathological processes of Alzheimer's disease. The current study investigated the relationship between IGF-1 and IGFBP-3 serum levels and cognitive impairment, including Alzheimer's disease.
