Brief Summary

Traumatic Brain Injury (TBI) is a prevalent disorder developed by military personnel. While some individuals recover function within months after injury, others continue to suffer from cognitive problems months to years later and may not become evident immediately, particularly for the recently transitioned veteran. Chronic TBI cases may include persistent difficulties in cognition that negatively impact employment and personal relationships. The investigators will test and evaluate software-based interventions aimed at improving cognition in veterans experiencing everyday life cognitive deficits due to TBI. The interventions will be administered on a computer using a tele-health approach. Two conditions will be compared, an active condition challenging memory, inhibitory control and planning, and a context-matched control condition that is lower on these challenge levels.

    change is evaluated from the beginning of the intervention to after completion (1 month in between)

  • Task-based functional Magnetic Resonance Imaging (fMRI)

    change is evaluated from the beginning of the intervention to after completion (1 month in between)

  • Automated Neuropsychological Assessement Metrics (ANAM)

    change is evaluated from the beginning of the intervention to after completion (1 month in between)

  • Traumatic Brain Injury (TBI) Awareness Questionnaire

    change is evaluated from the beginning of the intervention to after completion (1 month in between)

Study Arms (2)

Expedition: Strategic Advantage

ACTIVE COMPARATOR

Software-based intervention simulating daily life cognitive challenges. Delivered 1 hour per day, 5 days per week for 4 weeks. Includes 8 check-in phone calls with an experimenter. Includes escalating challenge levels.

Behavioral: Expedition

Expedition: Informational Advantage

PLACEBO COMPARATOR

Software-based intervention simulating daily life cognitive challenges. Delivered 1 hour per day, 5 days per week for 4 weeks. Includes 8 check-in phone calls with an experimenter. Includes capped challenge levels.

Behavioral: Expedition

Interventions

ExpeditionBEHAVIORAL

On a laptop computer participants work on simulated daily life activities including packing for a trip, navigating a transit system, and learning at museum attractions. The intervention increases difficulty as participants accomplish goals. We are testing the effects of this performance challenge on executive function measures.

Eligibility Criteria

Age19 Years - 55 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • male and female military veteran adults between the ages of 19 to 55 years (served in the military (any branch))
  • who have sustained a traumatic brain injury at least 3 months previously
  • who can comprehend simple instructions, perform the tests, and take part in the intervention training
  • Selection criteria will also include participants who can safely have an MRI, who can tolerate at least 2 hours of intervention sessions at a time, and who can participate in tasks involving motor abilities such as use of at least one arm and hand
  • No racial/ethnic groups will be excluded, although the patients must be able to speak, read, and comprehend English well enough to participate in the testing and treatment sessions, since the assessments are not normed or translated in other languages at this time.

You may not qualify if:

  • someone who is not proficient in reading, comprehending, and speaking English,
  • has pre-existing cerebral palsy, mental retardation, autism, epilepsy, schizophrenia, or pervasive developmental disorder.
  • Individuals with psychosis, active behavioral disorder, or uncontrolled epilepsy will be excluded.
  • Pregnant women will be excluded, since the effects of the treatment or the procedures on a fetus are unknown.
