Compositions and methods for treating traumatic brain injury
The present invention relates, in certain embodiments, to methods for preventing and/or treating neurodegenerative damage (e.g., secondary cascade of neurodegenerative damage) and improving functional outcomes (e.g., outcomes associated with cognitive, behavior and sensorimotor function) caused by traumatic brain injury using neuroprotective lipoyl compounds. The present invention also provides, in various embodiments, compositions for use in treating and/or preventing TBI in a subject in need thereof, compounds for use in the manufacture of a medicament for treating and/or preventing TBI in a subject in need thereof, and methods of preparing a pharmaceutical composition for treating and/or preventing secondary brain damage caused by TBI.
1. A method for treating traumatic brain injury in a subject in need thereof, comprising administering to the subject an effective amount of a compound of the following structural formula:
or a pharmaceutically acceptable salt or prodrug thereof.
2. The method of claim 1 , wherein the method is a method for treating neurodegenerative damage caused by traumatic brain injury.
3. The method of claim 2 , wherein the neurodegenerative damage affects the hippocampus region of the brain.
4. The method of claim 3 , wherein the neurodegenerative damage to the hippocampus region of the brain affects cognitive function associated with learning and memory.
5. The method of claim 2 , wherein the neurodegenerative damage affects sensorimotor function.
6. The method of claim 2 , wherein the neurodegenerative damage is associated with a focal or diffused traumatic brain injury.
7. The method of claim 2 , wherein the neurodegenerative damage is secondary damage at a site other than the site of the primary lesion.
8. The method of claim 1 , wherein the method is a method for improving a functional outcome following traumatic brain injury.
9. The method of claim 8 , wherein the functional outcome is associated with cognitive, behavior or sensorimotor function in the subject.
