Autism Clinical Trial - Sensory Phenotypes of Autism Spectrum Disorder

Status Recruiting

Clinical Trial Summary

This project plans to establish sensory phenotypes of a Taiwanese ASD cohort across lifespan, including variety of sensory modalities, sensory domains, and clinical correlates. Also, we will clarify the relationship between sensory phenotypes and social impairment by two specific sensory-social paradigms targeting eye gaze avoidance and social touch anxiety, as well as the atypical neural representation of ASD during eye gaze and viewing social touch by fMRI and EEG.

Clinical Trial Description

Sensory disturbance of autism spectrum disorder (ASD) are life-long highly-impairing challenges for the individual. Anxiety and fear around the sensory issues significantly threatens the psychological and mental health. As a newly introduced diagnostic criteria of ASD, sensory characteristics becomes a recent focus of ASD research. The ASD population is aging, how their sensory features naturally change with age is particular relevant for their adaptation. However, current literature are limited to childhood and young adults and mostly rely on behavioral report, lacking a clear whole picture of changing sensory phenotype in terms of different sensory modality and sensory domains. Besides, how sensory characteristics in ASD can be quantified by objective measures or explored by qualitative approach, how the sensory sensitivity contributes to the core social deficits in ASD such as eye gaze or social touch avoidance are unclear. This project plans to achieve the following aims: 1. Establish sensory phenotypes of a Taiwanese ASD cohort across lifespan, including variety of sensory modalities (i.e., visual, tactile, auditory, smell/taste, proprioception, etc.), sensory domains (i.e., low registration, sensory seeking, sensory sensitivity, and sensory avoiding), and clinical correlates. 2. Clarify the relationship between sensory phenotypes and social impairment by two specific sensory-social paradigms targeting eye gaze avoidance and social touch anxiety, which are hallmarks of ASD. Factors of emotion types as well as familiarity of faces or social/object touch will be manipulated to examine how they moderate eye tracking and pupil response. 3. Identify the atypical neural representation of ASD during eye gaze and viewing social touch by fMRI and EEG. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
