Apathy improvement
downin humans1
Frontal white matter hyperintensity volume is associated with apathy improvement in humans (Interaction β = 0.186, SE = 0.076; FDR-adjusted p = 0.048).
“This effect was driven by improvements in apathy (frontal: β = 0.186, SE = 0.076, FDR-adjusted p = 0.048;”

Neuropsychiatric symptom improvement
downin humans1
Frontal white matter hyperintensity volume is associated with neuropsychiatric symptom improvement in humans (Interaction β = 0.229, SE = 0.070; FDR-adjusted p = 0.007).

Neuropsychiatric symptoms are associated with frontal white matter hyperintensity volume in humans.

In a six-month trial of 51 people with vascular mild cognitive impairment, lower volumes of bright brain areas were linked to greater symptom reductions.In a six-month trial of 51 people with vascular mild cognitive impairment, lower volumes of bright brain areas were linked to greater symptom reductions.
