Study explores impact of parental Alzheimer’s on tau protein spread in the brain

While some studies have suggested that having a mother with Alzheimer's disease may put you more at risk of developing the disease, a new study finds that having a father with the disease may be tied to a greater spread of the tau protein in the brain that is a sign of the disease, according to a study published on April 9, 2025, online in Neurology®, the medical journal of the American Academy of Neurology.
