Takeaway
Amyloid-beta (Aβ) deposition is associated with an age-related increase in white matter abnormalities.
Why this matters
Aβ deposition precedes onset of Alzheimer’s disease (AD) and may be associated with age-related white matter abnormalities.
Pathological white matter changes constitute a core feature of AD pathogenesis.
Few studies have evaluated the relationship between Aβ deposition and white matter changes in middle-aged adults.
