Official title

Imaging Biomarkers of Social Cognition and Pharmacologic Target Engagement in Autism Spectrum Disorder

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder that is increasing in prevalence, and is characterized by deficits in social communication and interaction across multiple contexts, and restricted, repetitive patterns of behavior, interests, or activities. The majority of individuals with ASD have poor outcomes in the area of social functioning; however, there are no medical treatments available that target the core social communication deficits. The goal of the proposed research is to understand the neurobiological role of an imbalance in excitatory (glutamate) and inhibitory (gamma-aminobutyric acid, GABA) neurotransmission in the social cognition deficits in ASD, and to develop proton magnetic resonance spectroscopy as a measurement of target engagement to measure the ability of a medication, gabapentin, to increase cortical GABA levels. Spectrally-edited proton magnetic resonance spectroscopy (1H-MRS) provides an ideal method for measuring cortical GABA levels. All proposed studies will be in 70 adolescents (male and female) with ASD (age 13 to 17 years). Specific Aim 1: To measure correlations of 1H-MRS GABA levels in the anterior cingulate cortex (ACC) and occipital cortex (OC) with clinical measures of social cognition at baseline. Specific Aim 2: To measure the effect of an initial one time dose of gabapentin on 1H-MRS GABA levels in the ACC and OC. The hypotheses are 1) that higher social cognition ability will be positively correlated with GABA in the ACC but not in the OC (a control, non-social cognition-related region) of individuals with ASD, and 2) that gabapentin will increase GABA levels in the ACC and OC of youth with ASD.
