"The cause and onset of Alzheimer’s is not entirely known. However, scientists were able to find scientific evidence to support the pathophysiological hypothesis of structural changes that lead to progression of the condition.""Even though family history and age are two major factors in developing the condition, cardiovascular health appears to be equally important to brain health. Scientists have found a connection between one’s cardiovascular condition and the risk for Alzheimer's disease. Up to 80% of patients with Alzheimer's also have cardiovascular disease, caused by a process called atherosclerosis, or hardening and narrowing of the arteries.""If we can keep our heart healthy by doing regular aerobic exercises, such as brisk walking or cycling, we may be able to increase high-density lipoprotein (HDL) cholesterol, the ‘good’ cholesterol, that removes excess cholesterol in the blood. Clear arteries mean sufficient blood flow to carry oxygen-rich red blood cells to the brain. This ultimately lowers the likelihood of developing Alzheimer’s disease.""A plant-based diet also keeps heart disease in check, thus lowering one’s risk for Alzheimer’s." "This is consistent with data showing that those who eat vegetarian appear 2 to 3 times less likely to become demented. And the longer one eats meat-free, the lower the associated risk of dementia. Globally, the lowest validated rates of Alzheimer’s in the world are rural India, where they eat low meat, high grain, high bean, high carb diets.""An Indian spice has also been identified as having the potential to deter Alzheimer's and Parkinson’s disease, a nervous system disorder that affects movement." "It's called turmeric. And inside turmeric is this amazing bioactive compound called curcumin."
