Dementia

Dementia is the general term for a decline in mental ability which is serious enough to have a negative impact on everyday life. It is not a specific disease, but rather a term that describes a range of symptoms, such as a decline in memory or thinking skills severe enough to reduce the ability to do everyday tasks. The most common forms of dementia are Alzheimer’s disease, which accounts for 60%-80% of dementia cases, and Vascular dementia, which occurs after a stroke. There are many conditions that can cause symptoms of dementia, some of which are reversible, such as thyroid issues and vitamin deficiencies.¹

Impact of coffee on Dementia

• Drinking 3-5 cups of coffee a day was associated with a 65% decreased risk of developing 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 dementia. The results showed that drinking 3-5 cups of coffee a day in mid-life would reduce the risk of developing 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
