Insulin resistance also raises your risk for heart disease, so it’s not surprising to find that heart disease is associated with Alzheimer’s as well.
Arterial stiffness (atherosclerosis) is associated with a hallmark process of Alzheimer’s, namely the build-up of beta-amyloid plaque in your brain. According to researcher Timothy Hughes, “the process of vascular ageing may predispose the brain to increased amyloid plaque build-up.”
Recent research also points out that heart disease increases your odds of developing Alzheimer’s — in fact, these two diseases share a number of risk factors.
According to a study published in the journal Radiology, shared risk factors include smoking, alcohol use, diabetes, high fasting blood sugar levels, and obesity.
These kinds of findings dovetail with the conclusions reached by neurologist Dr David Perlmutter, author of the two books: Grain Brain, and Brain Maker.
From his research, Dr Perlmutter has concluded that Alzheimer’s disease is primarily predicated on lifestyle choices and, in a nutshell, anything that promotes insulin resistance will ultimately also raise your risk of Alzheimer’s.
