Identifying individuals who are at risk for developing dementia, including Alzheimer’s disease, is critical for the development of new therapies and interventions to slow or reverse cognitive symptoms. But current strategies are limited, both in terms of accuracy and the ability to incorporate them into routine practice. Unlike cerebrospinal fluid biomarkers that require a spinal tap, plasma biomarkers can be extracted from the blood, making their collection much less invasive and much more appealing. In a new study led by investigators from Brigham and Women’s Hospital, researchers have measured circulating levels of insulin-like growth factor binding protein 2 (IGFBP-2), a potential biomarker for dementia. In a paper published in Annals of Clinical and Translational Neurology, the team reports that IGFBP-2 levels were associated with an increased risk of both…
