Patient B, female, 73 years old. She complained of headache, dizziness, and insomnia, but had no risk factors of cerebrovascular diseases. Sertraline therapy (50 mg/d) was performed for 1 year. TrackVis software displayed the fasciculi in the white matter. B displays LA of Fazekas grade 2; B1 displays the DTI image at baseline; and B2 displays the DTI image after 1-year treatment. The number of fasciculi in the white matter in B2 was significantly lower than in B1. DTI = diffusion tension imaging, LA = leukoaraiosis.
