Brain Activity Flow Patterns Analysis Using Evoked Response Potentials in Youth With ADHD, Bipolar Disorder, or Autism Spectrum Disorders: A Preliminary Study
An observational study of Attention Deficit Hyperactivity Disorder and Autism Spectrum Disorder, run by Massachusetts General Hospital at 1 site in United States.
Trial summary
The study aims to evaluate whether or not an EEG (a type of brain scan) is useful in diagnosing youth with either ADHD, BPD, ASD. Youth with ADHD, BPD, ASD, and healthy controls (without ADHD, BPD, and ASD) will undergo an EEG, and the results will be analyzed using brain activity flow pattern analysis (BAFPA).

About this study
The study aims to evaluate whether or not an EEG (a type of brain scan) is useful in diagnosing youth with either ADHD, BPD, ASD. Youth with ADHD, BPD, ASD, and healthy controls (without ADHD, BPD, and ASD) will undergo an EEG, and the results will be analyzed using brain activity flow pattern analysis (BAFPA). Twenty subjects with each disorder and twenty without any of the disorders under study (controls) will be evaluated. All subjects will be comprehensively assessed with structured diagnostic interviews and neuropsychological testing. All EEG analyses will be conducted under blind conditions. Conditional probability and receiver operating characteristic (ROC) analyses will examine the diagnostic utility of the EEG scan, using the clinical diagnosis of ASD as the gold standard.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
| Study group | Role | What they receive |
|---|---|---|
| ADHD | Youth diagnosed with ADHD. | |
| ASD | Youth diagnosed with an Autism Spectrum Disorder (ASD). | |
| BPD | Youth diagnosed with Bipolar Disorder. | |
| Healthy Controls | Youth not diagnosed with any psychiatric/psychological disorder. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Agreement between clinical diagnoses and the results of brain activity flow pattern analysis (BAFPA).
Subjects will undergo clinical diagnostic interviews and a comprehensive neuropsychological assessment, and then complete 1 EEG scan of approximately 1 hour. The results of the BAFPA will be compared to the results of the clinical diagnostic interviews.
Measured: Baseline
