Alzheimer's disease (AD) is a common type of dementia. It is an irreversible, progressive disorder that involves deterioration of the brain. Unfortunately, this deterioration often precedes symptoms by decades. Loss of memory and cognitive function can make it increasingly difficult to carry out daily activities independently. Genetic factors play a significant role in AD and are estimated to account for around 70% of cases. The genetic factor is linked to a decreased ability of the immune system to regulate inflammation in the brain. There is also a link between blood sugar regulation and the development/progression of AD and other forms of dementia. An anti-inflammatory diet that is supportive of the immune system and blood sugar levels is essential to managing the condition. The Mediterranean Diet is often used as a supportive diet for most forms of dementia.
