In the United States, dementia and Alzheimer's disease is the #2 cause of death [1] In Japan, which has a longer life expectancy than the United States, dementia and Alzheimers diseases is the #14 cause of death.[2]

According to the British Medical Journal, "The brain’s capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published on bmj.com today."[3] Cognitive decline, dementia and Alzheimer's disease are progressive conditions that happen over time.[4][5][6] In the United Kingdom, dementia and Alzheimer's disease are the second leading cause of death.[7]

According to the National Institute of Aging, "Memory problems are typically one of the first signs of cognitive impairment related to Alzheimer’s disease. Some people with memory problems have a condition called mild cognitive impairment (MCI). In MCI, people have more memory problems than normal for their age, but their symptoms do not interfere with their everyday lives."[8]

In the United States, dementia and Alzheimer's disease are the #2 cause of death [9] In Japan, which has a longer life expectancy than the United States, dementia and Alzheimers diseases are the #14 cause of death.[10] In 2014, The Washington Post indicated that a new study indicated that Alzheimer's disease was the 3rd leading cause of death in the United States, but this study did not include dementia as well.[11]

According to Harvard Health Publishing, which is under the Harvard University Medical School, "There's strong evidence that certain diets — like the Mediterranean diet, the DASH diet, and the MIND diet — can help improve cognitive function."[12] According to the Mayo Clinic, an individual can cut his/her risk of getting Alzheimer's disease through a healthier diet.[13] Diet is believed to play a significant role in the development of Alzheimer's disease with fish eating populations getting less Alzheimer's disease and meat/dairy eating populations getting more Alzheimer's disease.[14] For example, less than 1% of calorie intake in the USA comes from fish compared with 1.5% in the Mediterranean and 5% in Japan.[15]
