尽管关于自闭症谱系障碍(ASD)潜在神经机制的报道有限,但几种运动障碍伴随自闭症谱系障碍(ASD)已广为人知。运动相关皮质区的γ-氨基丁酸(GABA)水平调节健康参与者的几种运动表现。我们假设,异常的GABA浓度在主要运动区(M1)和辅助运动区(SMA)与不同的运动困难的ASD青少年/成人。我们发现,使用1H磁共振光谱测量的M1中GABA浓度增加,在需要增加肌肉力量的任务中显示出较低的运动表现,而SMA中GABA浓度较低与测量身体协调性的测试中得分较低相关。M1和SMA区域的神经抑制程度将有助于自闭症运动障碍的不同方面。
Several motor disabilities accompanied with autism spectrum disorder (ASD) are widely known despite limited reports of underlying neural mechanisms. Gamma-aminobutyric acid (GABA) levels in the motor-related cortical areas modulate several motor performances in healthy participants. We hypothesized that abnormal GABA concentrations in the primary motor area (M1) and supplementary motor area (SMA) associate with different motor difficulties for ASD adolescents/adults. We found that increased GABA concentrations in M1 measured using1H-magnetic resonance spectroscopy exhibited lower motor performance in tasks requiring increased muscle strength while lower GABA concentrations in SMA were associated with lower scores in tests measuring body coordination. The degrees of neural inhibition in the M1 and SMA regions would contribute to different dimensions of motor disabilities in autism.
