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.
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.
