Leukoaraiosis is a condition that affects the brain’s white matter, leading to changes in its appearance on medical imaging scans. While it’s often associated with aging, it can also occur due to various other factors. Understanding leukoaraiosis, its causes, symptoms, diagnosis, and treatment options is crucial for individuals and caregivers alike.
Leukoaraiosis refers to abnormal changes in the brain’s white matter, typically seen on MRI or CT scans. These changes appear as areas of increased brightness on the images and are associated with small vessel disease in the brain.
Types:
There are no specific types of leukoaraiosis. However, it can vary in severity from mild to severe, depending on the extent of white matter damage.
Causes:
