Alzheimer's Disease, Dementia

Alzheimer’s disease is the most common form of dementia, which is a general term for memory loss and other intellectual abilities severe enough to impact negatively on everyday life. Alzheimer’s disease accounts for 60%-80% of dementia cases. Alzheimer’s is a progressive disease, where dementia symptoms worsen over time.1


Impact of coffee on Alzheimer’s disease and dementia

  • Drinking 3-5 cups of coffee a day was associated with a 65% decreased risk of developing Alzheimer’s or dementia
  • Tea drinking had a far less evident impact, indicating the benefits are with coffee, rather than purely caffeine


Two studies combined tea drinking and coffee drinking to study their impacts on Alzheimer’s disease and dementia. The results showed that drinking 3-5 cups of coffee a day in mid-life would reduce the risk of developing Alzheimer’s disease or dementia in late-life by approximately 65%. The impact tea had was far less evident, indicating that the effect is not just the caffeine, but other components of coffee.2
