Normal Quantitative EEG (qEEG) Dataset (NormalEEG)

August 8, 2022 updated by: Intermountain Health Care, Inc.

Normal Quantitative EEG (qEEG) Dataset for the Use in Comparison With Patients Suffering Carbon Monoxide (CO) Poisoning

In this study, the investigators will collect EEG data in normal, healthy volunteers without a history of prior brain injury. This data will be analyzed by computer (quantitative, or qEEG) and stored in a normative database so that, in the future, the investigators can better understand and characterize the brain damage that can result from carbon monoxide (CO) poisoning and other types of brain injury.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a pilot, prospective, non-comparative, non-invasive, minimal risk research study to obtain qEEG data on normal, healthy individuals to include in a normal control database for use in comparison with patients with CO poisoning and other types of brain injury. The use of anti-depressant medication use is relatively common in the general adult population. There is varying opinion whether anti-depressant medication alters an otherwise normal clinical EEG. We have included healthy individuals taking anti-depressant medication to determine if those medications influence the EEG. The EEG data will be collected, analyzed, and stored for use in future research studies and for clinical care. Evaluating patients with qEEG methodology may assist in diagnosis and treatment.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 55 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Ages 18-35, no antidepressant use
Ages 18-35, up to 15 males and 15 females, no antidepressant use
Procedure: Electroencephalography
Electroencephalography (EEG) is a relatively inexpensive measurement of basic brain activity. Traditional EEG techniques rely on the clinician to visually examine the electrical current waveforms to identify abnormal signal patterns and slowing. Abnormalities on EEG have been reported following CO poisoning, though the literature is scarce. While current EEG technologies record EEG signals digitally, rather than writing directly to paper, computer-assisted analysis of the data (quantitative EEG, or qEEG) has not been widely embraced, in part because clinicians are unsure what patterns revealed by computer-assisted analysis represent abnormal activity.
