What it is
White matter hyperintensities are tiny areas that appear bright on certain MRI sequences. “Nonspecific” means they do not point to one clear cause on imaging alone.
How common is it?
Common, and they increase with age and with things like high blood pressure. Many are found incidentally.
What's usually next
Your doctor considers them alongside your age, blood pressure, symptoms, and history. Managing cardiovascular risk factors is often part of the plan.
