are changes such as forgetting how to do things that are not considered “normal”. The importance of understanding that the changes most frequently observed and noticed on a daily basis concerning aging loved ones is imperative. While mild cognitive impairment can be considered a normal part of aging, the differences must be noted. In one study by J. Shagam, it was noted that while Diabetes and Hypertension are not considered part of normal aging, they would be classified under mild cognitive impairment. With this being said, it is important to differentiate the differences with what can be potentially harmful and what is not. It is difficult to accurately diagnose dementia due to the fact that most people are unaware of what to be looking for and also because there is no specific test which can be given as a diagnostic tool. What is even more evident is that the symptoms among dementia, Alzheimer's and Parkinson's related dementia tend to go beyond just one ailment. While there are different forms of dementia, Vascular dementia as it would sound is associated with vascular cautions. This form of dementia is not a slow deterioration but rather a sudden and unexpected change due to heart attack or stroke significantly reducing blood to the brain. Research has shown that persistent hypertension can be contributory to the breakdown of the BBB. The blood-brain barrier (BBB) serves as a “gatekeeper” for the brain by keeping out water and other substances. Various studies show that as the brain ages the blood-brain barrier starts to break down and become dysfunctional. There are different ways to measure the thinning of the BBB and one that most are familiar with is imaging, this consists of taking pictures of the brain using CT scans, MRI, or PET scans. Previous research also indicates that with aging and the thinning of the BBB, cognitive changes were also occurring within the section of the brain known as the hippocampus. This shows a relationship between aging and the thinning of the BBB and its effects on the brain. Also indicated by the aging brain are learning and memory impairments. While changes to the BBB are not a cause of impairment to cognitive functions alone research suggests that there is a relationship. Another impairment which is indicative of brain aging and the breakdown of the BBB is the accretion of iron. Too much iron in the body
