My doctor told me I had a bunch of white matter hyperintensities but never showed me them on any scan, so I don't know the size, location or any intervention needed, because my doctor knew nothing and did nothing.
This told me nothing useful. Like how to reverse white matter hyperintensities.
New study reveals age-related brain changes influence recovery after stroke

- Summary:
- A new study has revealed that areas of age-related damage in the brain relate to motor outcomes after a stroke -- a phenomenon that may be under-recognized in stroke research. The new observational study looked at the relationship between stroke recovery and white matter hyper-intensities (WMHs) -- areas of age-related damage in the brain's white matter, which represent vascular dysfunction and are known to impact cognitive functions.

A new study by a global team of researchers, led by Sook-Lei Liew, PhD, of USC's Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI), has revealed that areas of age-related damage in the brain relate to motor outcomes after a stroke -- a phenomenon that may be under-recognized in stroke research. The study was published online on May 3, 2024, in Neurology®, the medical journal of the American Academy of Neurology.
A stroke often leads to motor impairment, which is traditionally linked to the extent of damage to the corticospinal tract (CST), a crucial brain pathway for motor control. Signaling along the CST is involved in a variety of movements, including walking, reaching, and fine finger movements like writing and typing. However, stroke recovery outcomes aren't fully predicted by damage to the CST, suggesting other factors are at play.
