摘要:

目的 采用功能性近红外光谱技术(fNIRS)探究汉语发展性阅读障碍(DD)儿童和典型发育(TD)的健康儿童在静息态下全脑网络的连接特征。

方法 2024年11月至12月,选取复旦大学附属儿科医院6~12岁DD儿童19例(DD组),同时招募年龄和性别匹配的TD儿童18例(TD组),选取额叶皮质(FC)、颞叶皮质(TL)、枕叶皮质(OL)和顶叶皮质(PL)脑区为感兴趣区,采用fNIRS采集两组全脑静息态数据,持续5 min。基于氧合血红蛋白在时间序列上的浓度,计算两组静息态下的功能连接强度,比较两组功能连接强度和脑网络的差异。

结果 DD组全脑功能连接强度高于TD组(t = 2.100, P < 0.05)。DD组右侧OL-右侧FC (t = 2.426, P < 0.05)、右侧OL-左侧FC (t = 2.483, P < 0.05)、右侧TL-右侧FC (t = 2.568, P < 0.05)和右侧TL-左侧FC (t = 2.304, P < 0.05)功能连接强度大于TD组。两组全脑功能连接差异的主要区域位于右侧背外侧前额叶皮质、右侧视觉联合皮质、右侧额叶皮质、左侧额眶区、左侧视觉联合皮质、左侧初级视觉皮质和右侧初级皮质运动区。

结论 DD儿童静息态下右侧枕叶、颞叶及二者与前额叶之间的连接强度较强,提示可能存在右脑代偿左脑阅读网络功能不足的现象。

Abstract:

Objective To examine resting-state whole-brain network connectivity in children with Chinese developmental dyslexia (DD) and typically developing (TD) children using functional near-infrared spectroscopy (fNIRS).

Methods From November to December, 2024, 19 DD children aged six to twelve years in Children's Hospital of Fudan University were enrolled, along with 18 TD children matching age and sex. Regions of interest included frontal cortex (FC), temporal lobe (TL), occipital lobe (OL) and parietal lobe (PL). Resting-state data were acquired by fNIRS for five minutes in both groups. Functional connectivity strength was calculated at rest, and between-group differences in connectivity strength and brain networks were compared, based on the time series of oxyhemoglobin concentration.

Results The whole-brain functional connectivity strength was higher in DD group than in TD group (t = 2.100, P< 0.05). Connectivity between the right OL-right FC (t = 2.426, P< 0.05), right OL-left FC (t = 2.483, P < 0.05), right TL-right FC (t = 2.568, P < 0.05) and right TL-left FC (t = 2.304, P < 0.05) were stonger in DD group than in TD group. The major regions exhibiting differences of whole-brain connectivity between two groups were the right dorsolateral prefrontal cortex, right visual association cortex, right frontal cortex, left orbitofrontal cortex, left visual association cortex, left primary visual cortex and right primary motor cortex.

Conclusion Children with DD exhibited significantly stronger connectivity in the right occipital and temporal lobes, as well as between these regions and the prefrontal cortex, suggesting possible right-hemispheric compensation for insufficiency in the left-hemisphere reading network.

Key words: developmental dyslexia, functional near-infrared spectroscopy, resting state, whole-brain functional connectivity
