Abstract
To investigate the correlation between lateralization of cerebral basal ganglia hemorrhage and handedness. Medical records and computed tomography (CT) scans for 84 patients with primary hypertensive intracerebral hemorrhage (ICH) in basal ganglia were reviewed. Data of gender, age, handedness, and location of basal ganglia hematoma were statistically analyzed. Data of age, gender, handedness, health condition, and mean blood flow velocity (BFV) in middle cerebral arteries (MCAs) and anterior cerebral arteries (ACAs) on both sides of 114 healthy individuals were statistically analyzed. We found out that the patients with right basal ganglia hemorrhage were mostly left-handed, while patients with left basal ganglia hemorrhage were mostly right handed (p=0.021, r=0.251). And the mean BFV in the right MCAs of left-handed ones are relatively higher, the mean BFV in the left MCAs of right-handers are relatively higher (p=0.008, r=0.248). There 's a correlation between lateralization of cerebral basal ganglia hemorrhage and handedness.
Highlights
Spontaneous intracerebral hemorrhage (ICH) accounts for 10% to 30% of all strokes[1]
At the end of the first phase, we found out that 48 subjects were patients with left basal ganglia hemorrhage, and 36 (12 left-handed, 24 right-handed) subjects were patients with right basal ganglia hemorrhage
To the failure of detecting the blood flow, and 15 subjects were excluded for the abnormal blood flow velocities on one or both sides[8]
Summary
Spontaneous intracerebral hemorrhage (ICH) accounts for 10% to 30% of all strokes[1]. There are several modifiable risk factors for spontaneous ICH. Hypertension is by far the most important and prevalent risk factor, directly accounting for about 60% to 70% of cases[2,3]. Hypertensive ICH typically occurs in the basal ganglia (putamen, thalamus, or caudate nucleus), pons, cerebellum, or deep hemispheric white matter[4]. More than 50% of all spontaneous ICH occurs in the basal ganglia[5]. Based on the hematoma location, basal ganglia hemorrhages can be divided into left basal ganglia hemorrhages and right basal ganglia hemorrhages
