Poor sleep impacts the risk of long-term cognitive decline in Hispanic/Latino middle-aged and older adults differently than it does in non-Hispanic adults, according to research led by University of Miami Miller School of Medicine neurology faculty and the largest long-term study of U.S. Hispanic/Latinos to date.

During seven years of follow-up, Hispanics/Latinos were more likely to develop cognitive declines in processing speed, mental flexibility, and verbal memory, if they had sleep disordered breathing, such as obstructive sleep apnea, and long sleep duration of nine or more hours.

The risk was especially high in middle-aged adults without metabolic syndrome and women without obesity or metabolic syndrome, according to the paper published in Alzheimer’s & Dementia, the journal of the Alzheimer’s Association. Read the full story
