[Controlled arterial hypertension and blood-brain barrier damage in patients with age-related cerebral small vessel disease and cognitive impairments].

BBB permeability is a universal mechanism of NAWM and gray matter damage that supports the progression of WMH in CMA patients with controlled AH and without AH. The relationship of increased BBB permeability with slight deviations of ABPM can be explained by common mechanisms of their development due to endothelial dysfunction due to CMA and also points to the utility of more aggressive AH treatment. It is advisable to study the effect of antihypertensive and vascular drugs on BBB permeability with a view to their potential use in CMA.
