Cholesterol & Brain Health

What’s good for your Heart is good for your Brain.

Cholesterol plays a critical role in brain health. While our brain needs cholesterol to function, too much LDL (“bad” cholesterol) can damage blood vessels, reduce blood flow to the brain, and increase the risk of stroke and dementia.

The good news? Small lifestyle changes can help manage our cholesterol and protect both our heart and our brain.

Brain Benefits of Healthy Cholesterol Levels

  • Supports healthy blood flow to the brain, which provides oxygen & nutrition

  • Reduces risk of stroke and vascular dementia

  • Lowers inflammation, a key factor in cognitive decline

  • Protects white matter, which helps brain regions communicate

  • Promotes better memory and processing speed

What the Science Says

  • High LDL cholesterol in midlife is associated with increased risk of Alzheimer’s disease and vascular dementia.

  • Elevated cholesterol may contribute to plaque buildup in brain arteries, leading to silent strokes or reduced cognitive function.

  • Managing cholesterol can help preserve brain volume and function over time.
