About

The goal of this clinical trial is to find out if sulforaphane (SFN) can improve social skills and behavior in people with Autism Spectrum Disorder (ASD). ASD is a developmental disorder that affects how children and teenagers interact with others. The number of people diagnosed with ASD has been rising, putting a lot of pressure on families and society. The investigators hope this study will lead to new treatments.

The main questions the investigators want to answer are:

Can sulforaphane help improve social communication in people with ASD? How does sulforaphane affect the balance of certain chemicals in the brain?

The investigators will recruit 50 participants aged 12 to 34 diagnosed with ASD and 30 healthy volunteers for comparison. Participants will:

Take 3 capsules of sulforaphane each day for 8 weeks. Complete regular psychological tests, undergo brain scans, and have their brain activity monitored to assess the treatment's effectiveness.

Through this study, the investigators aim to discover the potential benefits of sulforaphane for individuals with ASD and provide new insights for future treatment options.

Full description

This study aims to investigate the mechanisms by which sulforaphane (SFN) ameliorates the excitatory/inhibitory imbalance in patients with Autism Spectrum Disorder (ASD). ASD is a pervasive developmental disorder characterized by impairments in social communication, interaction, and stereotyped behaviors. In recent years, the prevalence of ASD has been rising, imposing a significant burden on families and society. Although current primary interventions focus on educational training, there is a lack of effective biological treatments. Preliminary studies have demonstrated that sulforaphane can safely and effectively improve core clinical symptoms in Chinese patients with ASD, showing significant associations with metabolites related to excitatory/inhibitory balance, such as taurine and phosphatidylserine.

This open-label study will recruit 50 ASD patients aged 12-34 years and 30 healthy controls for an 8-week clinical trial. The study will employ psychological and behavioral assessments, electroencephalography (EEG), and magnetic resonance imaging (MRI) to comprehensively evaluate changes in clinical phenotype and neurotransmitter levels in ASD patients. The primary outcome measure will be improvements in social communication, while secondary measures will include changes in other clinical symptoms and neurophysiological characteristics.

Through this study, the investigators aim to gain a deeper understanding of the effects of sulforaphane on ASD patients, providing a new theoretical foundation and clinical evidence for the precise treatment of ASD.
