Vascular Risk Factors : Narrowing Arteries in the Head = Alzheimer's Risk Increase

  Researchers from the Atherosclerosis Risk in Communities (ARIC) Neurocognitive study demonstrated that hardening of the arteries in the head is associated with mild cognitive impairment and dementia.
  In MCI and dementia patients with posterior (back of the brain) cerebral watery plaque had 44% higher prevalence of MCI than without it. Dementia risk was increased threefold in those with anterior cerebral (front of the brain) artery plaque and twofold in those with narrowing > 70% or involvement of > vascular territories.
  Again, as per my last review, decreasing vascular risk factors (obesity, diabetes, hypertension and high cholesterol) decreases hardening if arteries inside the head and decreases cognitive impairment.
