Abstract
The aim of this report was to investigate the clinical outcome of deep brain stimulation (DBS) for autism spectrum disorder (ASD) and the functional and structural changes in the brain after DBS. We present a 14-year-old boy with ASD and self-injurious behavior (SIB) refractory with medical and behavioral therapy. He was treated by bilateral nucleus accumbens (NAc) DBS. Remarkable clinical improvement was observed following NAc DBS. Brain fluorodeoxyglucosepositron emission tomography (FDG-PET) and magnetic resonance imaging (MRI) volumetric studies revealed that the metabolism in the prefrontal and the frontal cortex as well as the occipital cortex was markedly decreased in association with the decreased cortical volumes in those areas 2 years after NAc DBS. The therapeutic potential of NAc DBS is suggested for the clinical improvement of patients with ASD and SIB with structural and functional changes after DBS.
