  • Diagnosis of Alzheimer's disease
  • Clinical Dementia Rating global score of 0.5 or 1 (very mild or mild dementia)
  • Agreed cooperation from an appropriate study partner
  • Speaks English as primary language
  • No medication changes in past 30 days

  • Resides in a nursing home or dementia special care unit, or cannot control diet
  • A potentially confounding serious medical risk (e.g., diabetes requiring insulin; cancer requiring chemotherapy or radiation within the past 5 years; or a recent heart attack, angioplasty, or other cardiac event)
  • Participating in another clinical trial or using an investigational drug or therapy within 30 days of screening
  • History of renal stones

Participants will be randomly assigned to one of two diets for 3 months.

  • The ketogenic diet is a high-fat, low-carbohydrate diet (approximately 70 percent fat, less than 10 percent carbohydrate, and 20 percent protein). The diet will encourage 4 or more servings of non-starchy vegetables and 1/2 cup of berries daily. Participants will also take daily supplements.
  • The Therapeutic Lifestyle Changes diet is low in fat and cholesterol; high in fruits, vegetables, and whole grains; and moderate in protein (20 to 35 percent fat, 50 to 60 percent carbohydrate, and approximately 15 percent protein). Participants will be encouraged to eat two or more servings of fruit and five or more servings of vegetables per day.

Researchers will measure changes in cognitive performance, including memory and reaction times, using several assessments and tests.
