A combination of diet and lifestyle changes decreases Alzheimer’s-like symptoms in dogs more than either treatment does on its own, a new study shows. The findings show the importance of taking multiple approaches to arrest the disease in humans, the authors say. Their results also provide evidence supporting recent research that suggests plaque deposits in the brain are not the cause of Alzheimer’s.

Alzheimer’s disease usually strikes people over the age of 60 and causes memory loss, shrinking brain tissue and eventually death. People with the disease get plaques in their brains made up of a small protein called amyloid-beta, which clumps together and disrupts brain signals. 

Research suggests diet and exercise can improve human brain function and defend against Alzheimer’s, but researchers aren’t sure why. Dogs naturally accumulate the same brain plaque, and though they don’t get Alzheimer’s, they do experience age-rel
