Sex differences in Alzheimer’s disease blood biomarkers in a Caribbean population of African ancestry: The Tobago Health Study

abstract blood cells rendering

Dr. Rosano is the lead investigator on a new publication, Sex differences in Alzheimer’s disease blood biomarkers in a Caribbean population of African ancestry: The Tobago Health Study.

Alzheimer’s disease (AD) is increasing in the Caribbean, especially for persons of African ancestry (PAA) and women. However, studies have mostly utilized surveys without AD biomarkers.

In the Tobago Health Study (n = 309; 109 women, mean age 70.3 ± 6.6), we assessed sex differences and risk factors for serum levels of phosphorylated tau-181 (p-tau181), amyloid-beta (Aβ)42/40 ratio, glial fibrillary acidic protein (GFAP), and neurofilament light chain (NfL). Blood samples were from 2010 to 2013 for men and from 2019 to 2023 for women.
