Mice with many of the pathologies of Alzheimer's disease showed fewer signs of the disease when given a protein-restricted diet supplemented with specific amino acids every other week for four months, reports Science Daily.
Mice at advanced stages of the disease were put on the new diet. They showed improved cognitive abilities over their non-dieting peers when their memory was tested using mazes.
In addition, fewer of their neurons contained abnormal levels of a damaged protein, called "tau," which accumulates in the brains of Alzheimer's patients according to the study published online by Aging Cellast month.
Upcoming studies by USCDavis School of Gerontology Professor Valter Longo, the study's corresponding author, will attempt to determine whether humans respond similarly while simultaneously examining the effects of dietary restrictions on cancer, diabetes and cardiac disease.
