Alzheimer’s disease (AD) is the most common form of dementia with various risk factors including age, environmental factors such as brain injury and genetic factors, such as the E4 allele of the Apolipoprotein gene. Presence of the APOE4 allele increases AD risk by two- to four- fold. Recent studies have shown that mild traumatic brain injury (mTBI), even without loss of consciousness, increases risk of dementia diagnosis by more than two-fold in military personnel and is also a significant environmental risk factor for developing dementia in the general population. The gut-brain axis (GBA) or bi-directional communication between the brain and …

Dementia is a disorder characterized by a significant decline from baseline in one or more cognitive domains that interferes with independence. Prevalence of dementia worldwide is estimated at 50 million people, with that number expected to triple by 2030, coming with a cost of roughly $2 trillion. Clinically, dementia is diagnosed using cognitive evaluations, with varying domains affected and to different degrees depending on the underlying pathology and stage of disease. Alzheimer’s disease (AD) and vascular contributions to cognitive impairment and dementia (VCID) are the two leading causes of dementia, and both have pathologies which can be visualized using MRI. …
