Abstract

Background: The dorsolateral prefrontal cortex (DLPFC) is implicated in neuropsychiatric disorders. It is a primary target region for noninvasive brain stimulation (NIBS). BeamF3 is a simplified method of localization of DLPFC for neuromodulation. However, the accuracy of this method has not been examined in children.

Aim: To compare the localization of DLPFC via BeamF3 and 10-20 electroencephalogram (EEG) systems in adolescents with neuropsychiatric disorders.

Methods: Twenty adolescents (10-15 years) were recruited from the in-patient child and adolescent psychiatry unit of our center. DLPFC localization was done and compared between the BeamF3 and 10-20 EEG systems. DLPFC localization based on the BeamF3 method at anterior/anterolateral/lateral position was compared with 10-20 EEG systems in 70% of adolescents.

Results: The mean difference in DLPFC localization was 1.10 ± 0.81 cm (0-3 cm), with a difference of ≥1 cm in 70% of adolescents. This study found a difference between Beam F3 and 10-20 EEG systems in terms of localization of DLPFC in adolescents.

Conclusion: Comparison of these methods with MRI-guided methods may be necessary, especially when highly focal stimulation is desired for treatment in adolescents.

定位青少年背外侧前额皮质进行无创脑刺激：BeamF3和10-20脑电图系统的比较：一项横断面研究。

背景：背外侧前额叶皮层（DLPFC）与神经精神疾病有关。它是无创脑刺激（NIBS）的主要靶区。BeamF3是一种简化的DLPFC定位方法，用于神经调节。然而，这种方法的准确性尚未在儿童中得到检验。目的：比较BeamF3和10-20脑电图（EEG）对青少年神经精神障碍患者DLPFC定位的影响。方法：从我中心住院儿童青少年精神科招募20名10 ~ 15岁的青少年。对BeamF3和10-20脑电系统进行了DLPFC定位并进行了比较。在70%的青少年中，采用BeamF3方法在前位/前外侧/侧位定位DLPFC，并与10-20个EEG系统进行比较。结果：DLPFC定位平均差值为1.10±0.81 cm (0 ~ 3 cm)， 70%青少年DLPFC定位差值≥1 cm。本研究发现F3波束与10-20波束脑电图系统在青少年DLPFC定位方面存在差异。结论：将这些方法与mri引导的方法进行比较可能是必要的，特别是当青少年需要高度局部刺激治疗时。
