Detection of Hemodynamic Changes in TBI Population With Functional Near Infrared Spectroscopy

January 15, 2019 updated by: Ramon Diaz-Arrastia, Uniformed Services University of the Health Sciences
The goal of this project is to develop a test to assess frontal lobe function using a rapid, inexpensive, objective, and standardized method, without the need for expertise in cognitive test administration. Such methods would be particularly helpful in traumatic brain injury (TBI), where objective measures are needed, and would greatly expand the capacity to make such assessments in clinical practice and research.

Probability Sample

Study Population

Males and females (military health care beneficiaries and non military health care beneficiaries) age between 18 and 60 years who have a diagnosis of moderate or severe traumatic brain injury as well as age, gender, education matched non-TBI volunteers.

Description

Inclusion Criteria:

  • Able to read, write, speak and understand English

  • history of having sustained a TBI prior to enrollment. Evidence will be any one of the following 3 criteria:

    1. GCS 3 - 12
    2. Post-traumatic amnesia > 24 hours
    3. TBI-related abnormality on neuroimaging (either CT or MRI). (Some missing information about the initial injury (i.e. documentation of initial GCS) is not necessarily exclusionary if the bulk of the available history is indicative that the patient suffered a TBI and meets the inclusion criteria)

Exclusion Criteria:

  • Multiple sclerosis, pre- or co-existing
  • Stroke (other than stroke at the time of TBI)
  • Pre-existing developmental disorder
  • Pre-existing epilepsy
  • Pre-existing major depressive disorder
  • Pre-existing schizophrenia

Cohorts and Interventions

Group / Cohort
History of having sustained TBI
Males and females between 18 and 60 years who have a diagnosis of TBI
Control group
Control group with no history of TBI or concussion. Gender and age matched non-TBI volunteers

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measure of hemodynamic response function
Time Frame: Two years
In two population groups: TBI and non TBI, we will determine normative data for the cognitive parametric experiment by measuring the local hemodynamic response function with functional near infrared spectroscopy
Two years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Measure of the degree of impairment
Time Frame: Two years
Determine the relationship between hemodynamic response as measured by fNIRS and measures of neuropsychological and behavioral functioning obtained using measures from the NINDS Common Data Elements.
Two years
