Alzheimer's disease

A brain region critical for memory is smaller in older adults with fewer than 10 teeth than in those who have most of their teeth, suggesting that tooth loss may precede the development of dementia

A rare but potent genetic mutation that alters a protein in the brain’s immune cells, known as microglia, can give people as much as a threefold greater risk of developing Alzheimer’s disease. A new study by…
