About this trial

This is an interventional treatment trial for Traumatic Brain Injury focused on measuring severe, hypoxic-ischemic encephalopathy, stroke, intracranial hemorrhage, cerebral palsy, chronic, neurological injury

Eligibility Criteria

18 Years - 55 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. adults between 18 and 55 years of age

  4. onset or diagnosis of the injury or disease process greater than 6 months
  5. ability to obtain consent from the subject of their legally authorized representative (LAR)
  6. ability to speak English or Spanish *required for validated neurocognitive outcome testing) -

Exclusion Criteria:

  1. known history of:

    a) intellectual deficiency or psychiatric conditions likely to invalidate our ability to assess changes in cognition or behavior, b) recently treated infection, c) renal disease or altered renal function (screening serum creatinine > 1.5 mg/dL), d) hepatic disease or altered liver function (screening SGPT > 150 U/L or T. Bilirubin >1.3 mg/dL), e) cancer, f) immunosuppression (screening WBC < 3, 000 cells/ml), g) HIV+, h) chemical or ETOH dependency that in the opinion of the investigator would preclude participation in the study, i) acute or chronic lung disease requiring significant medication, oxygen supplementation, or mechanical ventilation, j) bleeding disorders including immune-mediated heparin-induced thrombocytopenia, k) known sensitivity to heparin, Lovenox, and pork products, l) individuals with mechanical prosthetic heart valves.

  4. diagnosed with a genetic or metabolic disorder related to the neurologic condition
  5. other acute or chronic medical conditions that, in the opinion of the investigator, may increase the risks associated with study participation
