Evaluating a Novel Method of EEG Evoked Response Potential Analysis in Concussion Assessment, Young Adults and Adults

Concussion, Brain Clinical Trial

Official title: Clinical Trial Protocol for the Evaluating a Novel Method of EEG Evoked Response Potential Analysis in Concussion Assessment, Young Adults and Adults

Status Withdrawn

Clinical Trial Summary

Concussion is widely recognized as a major public health concern in the United States and worldwide. Although many concussions resolve completely and spontaneously, almost 1 in 4 patients will go on to experience post-concussion syndrome (PCS). In the United States, PCS diagnoses have increased 100% from 2010-2015. Concurrently, recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. The purpose of this study is to explore the use of BNA in individuals who are diagnosed with PCS or have the risk of experiencing PCS due to a recent injury.

Clinical Trial Description

Mild traumatic brain injury, also known as concussion, occurs commonly in sport. The Centers for Disease Control and Prevention estimate that as many as 3.8 million sport-related concussions occur annually in the United States. Although many concussions resolve completely and spontaneously, almost 1 in 4 patients will go on to experience post-concussion syndrome (PCS). In the United States, PCS diagnoses have increased 100% from 2010-2015. Concurrently, recent advances in EEG evoked response potential analysis have led to a novel technique for assessing brain network activation (BNA) patterns. The purpose of this study is to explore the use of BNA in individuals who are diagnosed with PCS or have the risk of experiencing PCS due to a recent injury.

ElMindA, the sponsor of this study, has developed a novel method to automatically reveal functional networks of brain activity based on analysis of EEG Event Related Potential (ERP) data. This technological platform is capable of providing new metrics of brain function which can assist in patient evaluation and management. The analysis is done in two separate processes which are entirely separate and are performed independently of one another. First EEG data are recorded and analyzed from a group, or several groups, of subjects to establish a set of group patterns which characterized the brain network activity of the group. Second, EEG data from a single subject are processed to enable subject evaluation, as compared to the established group patterns. This individual analysis is the basis of the BNA scores computed for an individual subject.

Primary Objective:

• Exploratory (e.g. Hypothesis-generating) study designed to collect data that will aid in future understanding of the relationship between Post Concussion Syndrome and Electrophysiology. The results are primarily intended for scientific inquiry and development purposes.

Additional objectives:

• Exploring the relationship between the characteristics of early/acute stage Mild Traumatic Brain Injury and the subsequent development of PCS

• Collecting electrophysiological and clinical data that will serve as the basis for athlete brain health case studies.

Arm 1: Study staff will contact subjects tested in the past with BNA and were diagnosed with Post-Concussion Syndrome at their medical facility.

Arm 2: Eligible subjects treated at the study medical facility for acute concussion or Post Concussion Syndrome will be approached by the study staff.

Interested volunteers will complete a brief initial in person or phone consultation with a member of the study team and those who meet eligibility criteria and wish to participate will be invited for a study visit in the testing facility. During this visit, a member of the study team will describe the study in greater detail, verify subject eligibility, obtain informed written consent/assent for study participation, and record relevant demographic, medical history information, concussion history and clinical assessment questioners as provided by the subject or as available from subject's medical records. The subject will then have the EEG electrode cap placed on their head and will undergo the BNA test after a brief training and instructional session. ;
