After a mild or moderate traumatic brain injury (TBI), most brain cells survive. Yet they cannot work efficiently, and this can leave lasting problems with thinking and behavior.

What they work on

  1. Test how acute metabolic depression after TBI changes brain functional connectivity and reorganization over time in rats, using resting-state functional MRI with connectome analysis plus behavioral testing.
  2. Determine whether DHF, a small molecule that activates the BDNF receptor TrkB, reduces early metabolic depression and later enhances synaptic plasticity and cognitive outcome.
  3. Test whether DHF and exercise, alone or combined and given early or delayed, boost brain connectivity and function in male and female rats.
  4. Use statistically driven, subject-level measures of tissue damage, swelling and atrophy as covariates to assess whether offsetting metabolic depression potentiates rehabilitation.

More about the research

One proposed reason is metabolic depression (MD), a drop in the energy brain cells can produce in the early period after injury. Without enough energy, neural circuits cannot meet demand or rewire through plasticity. MD may therefore limit how much patients gain from rehabilitation. This project asks whether restoring brain energy early can make later rehabilitation work better.

Why it matters

People recovering from concussion and other TBI often have lasting cognitive problems, and rehabilitation helps them unevenly. If early energy failure in brain cells limits recovery, then a drug like DHF given with exercise could make rehabilitation more effective. This could include patients whose rehabilitation is delayed by other injuries. The work may inform the timing and design of treatment after brain injury.
