Sleep Apnea May Be Linked with Alzheimer’s Marker
It isn’t clear, however, if sleep apnea causes the buildup of “tau” protein tangles in the brain that are a marker for Alzheimer’s, or if the increased tau helps cause the apnea, the researchers said.
“Since tau accumulation is a hallmark of Alzheimer’s disease, an increase in tau raises concern that sleep apnea could make [people] with sleep apnea more vulnerable to Alzheimer’s,” said lead researcher Dr. Diego Carvalho, a neurologist at the Mayo Clinic in Rochester, Minn.
