Insulin fulfills an indispensable role in your body’s utilization of blood sugar (glucose). In type 2 diabetes and Metabolic Syndrome, insulin’s function of glucose uptake into the body’s cells is impaired due to a resistance to insulin that develops over time. This insulin resistance pattern which defines the disease process of the above mentioned disorders, is now seen as a link to the degenerative spiral that occurs in Alzheimer’s disease (AD) over and above the role of insulin in glucose metabolism in the brain. Insulin resistance and its role in inflammation, and impaired insulin function in the brain are now understood to be underlying pieces of the Alzheimer’s puzzle.

The Alzheimer’s Gene Puzzle – The ApoE4 Variant As A Risk Factor

The Alzheimer’s Gene Puzzle – The ApoE4 Variant As A Risk Factor

Genetic risk factors to Late Onset Alzheimer’s Disease (LOAD) are significant. A recent study of nearly 12,000 Swedish twin pairs, age 65 and older, determined that 58% to 79% of Alzheimer’s risk is genetic (1). This study showed that in male identical twins, when one brother had Alzheimer’s disease, the other developed the disease 45% of the time. In female identical twins, when one sister had Alzheimer’s disease, the other developed the disease 60% of the time. While this study did not delve into specific gene influences in LOAD, numerous studies have identified Apolipoprotein E4 (ApoE4), as a prominent genetic risk factor for LOAD. About 25% of the population has one copy of the ApoE4 gene and individuals with the the ApoE4 gene are estimated to make up approximately 40%-80% of the Alzheimer’s disease population. (2)
