Values are presented as mean ± standard deviation.

WMH: white matter hyperintensity, dWMH: deep-only WMH pattern in which WMHs are mainly located in the corticomedullary junction or deep white matter, accompanied by little or no periventricular WMH, dpWMH: WMH pattern that is commonly seen in individuals with cerebral small vessel disease, where main periventricular WMH with or without deep WMH is accompanied by one or more lacunes, WM, white matter.
