Abstract

OBJECTIVE

We used the amplitude of low-frequency fluctuation (ALFF) method to investigate spontaneous brain activity in patients with optic neuritis (ON) in specific frequency bands.

DATA AND METHODS

A sample of 21 patients with ON (13 female and eight male) and 21 healthy controls (HCs) underwent functional magnetic resonance imaging (fMRI) scans in the resting state. We analyzed the ALFF values at different frequencies (slow-4 band: 0.027-0.073 Hz; slow-5 band: 0.01-0.027 Hz) in ON patients and HCs.

RESULTS

In the slow-4 frequency range, compared with HCs, ON patients had apparently lower ALFF in the insula and the whack precuneus. In the slow-5 frequency range, ON patients showed significantly increased ALFF in the left parietal inferior and the left postcentral.

CONCLUSION

Our results suggest that ON may be involved in abnormal brain function and can provide a basis for clinical research.

摘要

目的

我们采用低频振幅（ALFF）方法研究视神经炎（ON）患者特定频段的自发脑活动。

数据与方法

21例ON患者（13例女性，8例男性）和21名健康对照者（HCs）在静息状态下接受功能磁共振成像（fMRI）扫描。我们分析了ON患者和HCs在不同频率（慢4频段：0.027 - 0.073 Hz；慢5频段：0.01 - 0.027 Hz）下的ALFF值。

结果

在慢4频率范围内，与HCs相比，ON患者脑岛和楔前叶的ALFF明显较低。在慢5频率范围内，ON患者左侧顶叶下部和左侧中央后回的ALFF显著增加。

结论

我们的结果表明，ON可能与脑功能异常有关，可为临床研究提供依据。
