Health Nucleus clients enroll presumed to be healthy, but some are found through our integrated assessments to have asymptomatic or pre-symptomatic health concerns, which now detected, can be treated through standard medical care.  White Matter Hyperintensities is one example.

White Matter Hyperintensities

Definition: Nonspecific changes to the blood vessels in the white matter tissue of the brain that cause a bright appearance on a brain Computed Tomography (CT) scan or Magnetic Resonance Imaging (MRI).

European Radiology, 2010.


  • Aging*
  • High blood pressure (hypertension)
  • High cholesterol (hypocholesteremia)
  • Insulin resistance -> Diabetes, Obesity
  • Coronary Artery Disease (CAD)
  • Chronic Kidney Disease
  • Smoking
  • Alcohol use
  • History of stroke

*Not everyone of age experience hyperintensities

Possible Disease Associations:

  • Stroke
  • Dementia
  • Depression
  • Decreased physical function (i.e. walking)

Lifestyle Modifications to help prevent further progression:

  • Smoking cessation
  • Drinking in moderation
  • Diet improvement
  • Maintain a healthy weight
  • Manage blood pressure
