NCT07047976

Brief Summary

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.

Outcome Measures

Primary Outcomes (2)

  • Social communication changes index

    Assessed by the Social Response Scale (SRS-II). This scale is used to evaluate the severity of social symptoms associated with autism spectrum disorders and includes five subdimensions: social awareness, social cognition, social communication, social motivation, and autism behaviors. The change in social communication scores from baseline to the end of the study period will be the primary outcome of interest. The critical value is 59.5, and the total score is the sum of all entries, with the lowest score of 0 and the highest score of 3 for each entry. The total score of this scale represents the severity of social functioning impairments in the participants, with higher scores indicating greater severity.

    At baseline, week 4, and week 8

  • Autism assessment index

    Autism was assessed using the Oregon State University Autism Rating Scale, DSM-5 (OARS-5), which includes the signs and symptoms of autism spectrum disorders described in the DSM-5. The scores include :1; Total number of symptoms. Every symptom that occurs (i.e., 1, 2, or 3 points) is recorded in the symptom count. 2. Weighted average severity. The clinician scored each item on a scale of 0, 1, 2 or 3 based on the parent's description of the particular problem. 3. Damage index. In Section C of OARS-5, after discussion with the child/adolescent's caregiver, the clinician will rate the level of support on a scale of 0(no support) to 3(maximum support). In the OARS-5 scale, higher scores indicate more severe symptoms.

    At baseline, week 4, and week 8

Secondary Outcomes (25)

  • Functional E/I Ratio in EEG

    At baseline, week 4, and week 8

  • Concentration Ratios of Neurotransmitters in Magnetic Resonance Spectroscopy

    At baseline, week 4, and week 8

  • Eye Movement Parameters During Cognitive Tasks

    At baseline, week 4, and week 8

  • Performance on the 'Reading the Mind in the Eyes' Test

    At baseline, week 4, and week 8

  • Score on the Frith-Happe Animations Task

    At baseline, week 4, and week 8

  • +20 more secondary outcomes

Other Outcomes (2)

  • Plasma metabolite levels assessment

Study Arms (1)

Sulforaphane Intervention Group for Autism Spectrum Disorder

EXPERIMENTAL
Dietary Supplement: Sulforaphane

Interventions

SulforaphaneDIETARY_SUPPLEMENT

This intervention involves the administration of Sulforaphane, a compound derived from glucoraphanin found in cruciferous vegetables. Participants will receive Avmacol® tablets, each containing 30 mg of glucoraphanin (approximately 68 μmol per tablet). They will take 3 tablets daily, resulting in a total daily dosage of approximately 90 μmol of Sulforaphane. The intervention will last for 8 weeks, during which participants will be monitored for clinical and biological outcomes.
