The method for treating traumatic brain injury in an individual includes the step of administering a therapeutically effective amount of a pharmaceutically acceptable gallium compound to a blood brain barrier of the individual within a therapeutically effective time period subsequent to the injury so as to reduce secondary injury in a brain of the individual. Secondary injuries include swelling of the brain after the initial injury, secondary lesions, hematomas, and edema. The effective amount and effective time period for the step of administering are established by test results disclosed in the present invention. Gallium compounds are shown to reduce oxidative stress levels in the brain, a metric for treatment of traumatic brain injury or concussion.

1. A method of treating traumatic brain injury in a mammalian individual, said method comprising the steps of: administering a therapeutically effective amount of a pharmaceutically acceptable gallium compound to a blood brain barrier of the individual within a therapeutically effective time period
1. A method of treating traumatic brain injury in a mammalian individual, said method comprising the steps of: administering a therapeutically effective amount of a pharmaceutically acceptable gallium compound to a blood brain barrier of the individual within a therapeutically effective time period subsequent to the injury so as to reduce secondary injury in a brain of the individual. 2. The method of treating traumatic brain injury, according to claim 1, wherein the effective amount reduces oxidative stress in said brain. 3. The method of treating traumatic brain injury, according to claim 1, wherein the effective amount ranges from 2-50 mg/kg. 4. The method of treating traumatic brain injury, according to claim 1, wherein the effective amount ranges from 2-20 mg/kg. 5. The method of treating traumatic brain injury, according to claim 1, wherein the effective time period ranges from 15 minutes to 30 minutes. 6. The method of treating traumatic brain injury, according to claim 1, wherein the effective time period is 30 minutes. 7. The method of treating traumatic brain injury, according to claim 1, wherein the effective time period ranges from 15 minutes to 24 hours. 8. The method of treating traumatic brain injury, according to claim 1, wherein the effective time period is as along as the rate oxidative stress increases, after said initial injury. 9. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is selected from a group consisting of: gallium nitrate, gallium citrate, gallium chloride, gallium fluoride, gallium phosphate, gallium carbonate, gallium acetate, gallium tartrate, gallium oxalate, gallium formate, gallium oxide, gallium sulfate, gallium arsenide, gallium maltolate, gallium 8-quinolinolate and hydrated gallium oxide, gallium pyridinones, gallium succinate, gallium gluconate, gallium 3-hydroxy-4-pyrone, gallium palmitrate, the tridocosahexaenonic acid salt of gallium, or other tri(alkylcarboxylato) gallium (III) compounds, gallium prophyrins, gallium transferrins, gallium pyridoxal isonicotinoyl hydrazine, and combinations thereof. 10. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is comprised of gallium nitrate. 11. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is comprised of a docosahexaenonic acid salt of gallium with one to three of the gallium ligands being from docosahexaenonic acid. 12. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is administered orally. 13. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is administered by injection. 14. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is administered by intraperitoneal injection. 15. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is administered by transdermal patch. 16. The method of treating traumatic brain injury, according to claim 1, wherein said gallium compound is administered by nasal spray. 17. The method of treating traumatic brain injury, according to claim 1, further comprising the step of: administering another therapeutically effective amount of said pharmaceutically acceptable gallium compound to said blood brain barrier of the individual after said therapeutically effective time period subsequent to the injury so as to continue reducing secondary injury at a brain of the individual. 18. The method of treating traumatic brain injury, according to claim 17, further comprising the step of: administering still another therapeutically effective amount of said pharmaceutically acceptable gallium compound to said blood brain barrier of the individual after administering said another therapeutically effective amount so as to continue reducing secondary injury at a brain of the individual.
