Alzheimer’s disease is one of the most common health conditions to hit members of the older population. While Alzheimer’s disease can also affect younger people, 5.2 million of those affected are aged 65 and older (out of the 5.4 million estimated cases of Alzheimer’s disease in the USA). Because of the widely perpetuated idea that forgetfulness and poor memory is “normal” for older adults, a lot of people with Alzheimer’s disease still go about their lives undiagnosed. 
Differentiating Dementia From Alzheimer’s Disease
Dementia is not a disease but a collective of symptoms attributed to the normal aging process of the brain – a syndrome but not a disease. As the brain undergoes natural wear and tear over the years, its function becomes affected and eventually flawed. This causes problems with memory, mental agility, language, understanding, and judgment – but not as severe as the neurological decline seen in Alzheimer’s disease. 
On the other hand, Alzheimer’s disease is widely regarded as an irreversible and progressive condition that affects the brain and causes debilitating problems in day-to-day living. This is a slow moving disease, often disregarded as dementia, with the affected person eventually losing the ability to perform basic skills of daily living like feeding one’s self and practice self-care activities. They eventually become fully dependent on others for care. 
Risk factors for developing Alzheimer’s disease include advanced age, familial history of the disease (a.k.a. genetics), hypertension, diabetes, heart disease, traumatic head injury, depression, and sleep disorders. However, the underlying cause of Alzheimer’s disease is still unknown. 
10 Foods To Fight Alzheimer’s Disease
One of the most recent studies linking olive oil intake and Alzheimer’s disease was published in 2015 by Rigacci. According to a review of recent literature, Rigacci concluded that the phenol content of olive oil was a promising substance to include in a person’s diet to fight Alzheimer’s disease. The review linked to other studies on the “Mediterranean diet” that uses olive oil as a main source of fat, leading to a reduced risk for heart disease, cancer, and cognitive decline caused by advancing age.
