1 Introduction According to the 2019 Global Burden of Disease data, stroke remains the second most common cause of mortality globally (1, 2). Acute ischemic stroke (AIS) is among the two main subcategories of stroke (3), which occurs due to focal cerebral hypoperfusion commonly caused by embolism and atherosclerotic disease (4, 5).

Introduction Cerebral small vessel disease (CSVD) is a group of clinical, imaging, and pathological syndromes caused by structural remodeling of small cerebral arteries and their distal branches, micro-arteries, capillaries, micro-venules, and small veins (1), frequently leading to vascular cognitive impairment (2). As the most important imaging method for the diagnosis of CSVD, brain MRI is often used to assess the severity of CSVD.

1. IntroductionIntracerebral hemorrhage (ICH) accounts for approximately 10–15% of all strokes and is associated with high morbidity and mortality (1–5). It has been reported that Asian populations (especially Japanese) experience ICH more frequently than Western populations (5, 6). Hypertension is the risk factor with the greatest influence on primary ICHs, and it is present in approx. 70% of patients who experience an ICH (7).
