Asymptomatic Moyamoya disease (MMD) impairs hemodynamic and cognitive function. The relationship between these changes, cerebral blood flow (CBF), and network connectivity remains largely unknown. The aim of this study was to increase understanding of the relationship between CBF, functional networks, and neurocognition in adults with asymptomatic MMD. We compared CBF and functional status in 26 patients with MMD and 20 healthy controls using arterial spin labeling and resting state functional magnetic resonance imaging sequences. At the same time, a detailed cognitive test was performed in 15 patients with no cerebral or lumen infarction who were selected by magnetic resonance imaging-T2 FLAIR screening. Compared to the controls, the patients showed varying degrees of decline in their computational ability (simple subtraction, p = 0.009; complex subtraction, p = 0.006) and short-term memory (p = 0.042). The asymptomatic MMD group also showed decreased CBF in the left anterior central and left inferior frontal gyri of the island flap with multiple node abnormalities in the brain network and reduced network connectivity. There was a significant association of these changes with cognitive decline in the MMD group. In patients with asymptomatic MMD, disturbance of CBF and impaired brain network connections may be important causes of cognitive decline and appear before clinical symptoms.

无症状烟雾病成年患者的脑灌注、执行控制网络、拓扑特征和神经认知受损

无症状烟雾病 (MMD) 会损害血流动力学和认知功能。这些变化、脑血流量 (CBF) 和网络连接之间的关系在很大程度上仍然未知。本研究的目的是增加对无症状 MMD 成人 CBF、功能网络和神经认知之间关系的理解。我们使用动脉自旋标记和静息状态功能磁共振成像序列比较了 26 名 MMD 患者和 20 名健康对照的 CBF 和功能状态。同时,对通过磁共振成像-T2 FLAIR筛查选出的15例无脑梗塞或管腔梗塞的患者进行了详细的认知测试。与对照组相比,患者的计算能力出现不同程度的下降(​​简单减法,p = 0.009;复减法,p = 0.006)和短期记忆(p = 0.042)。无症状 MMD 组还显示岛状皮瓣左前中央和左额下回的 CBF 降低,脑网络中存在多个节点异常,网络连接性降低。这些变化与 MMD 组的认知能力下降显着相关。在无症状 MMD 患者中,CBF 障碍和脑网络连接受损可能是认知能力下降的重要原因,并出现在临床症状之前。临床试验注册-网址:http://www.chictr.org.cn 唯一标识符:ChiCTR1900023610 无症状 MMD 组还显示岛状皮瓣左前中央和左额下回的 CBF 降低,脑网络中存在多个节点异常,网络连接性降低。这些变化与 MMD 组的认知能力下降显着相关。在无症状 MMD 患者中,CBF 障碍和脑网络连接受损可能是认知能力下降的重要原因,并出现在临床症状之前。临床试验注册-网址:http://www.chictr.org.cn 唯一标识符:ChiCTR1900023610 无症状 MMD 组还显示岛状皮瓣左前中央和左额下回的 CBF 降低,脑网络中存在多个节点异常,网络连接性降低。这些变化与 MMD 组的认知能力下降显着相关。在无症状 MMD 患者中,CBF 障碍和脑网络连接受损可能是认知能力下降的重要原因,并出现在临床症状之前。临床试验注册-网址:http://www.chictr.org.cn 唯一标识符:ChiCTR1900023610 CBF 障碍和脑网络连接受损可能是认知能力下降的重要原因,并出现在临床症状之前。临床试验注册-网址:http://www.chictr.org.cn 唯一标识符:ChiCTR1900023610 CBF 障碍和脑网络连接受损可能是认知能力下降的重要原因,并出现在临床症状之前。临床试验注册-网址:http://www.chictr.org.cn 唯一标识符:ChiCTR1900023610
