Summary

This trial is testing whether growth hormone can improve cognitive function in retired professional football players with growth hormone deficiency.

Who is the study for?
This trial is for retired NFL players under 76 years old with growth hormone deficiency (GHD) diagnosed by a neurologist and endocrinologist. They must understand the study, be willing to participate, and have been retired for at least one year. Those with diabetes, pre-existing brain diseases other than concussion or TBI, conditions affecting assessments, contraindications to GH therapy, active cancer, acute illnesses or untreated hormonal deficiencies cannot join.
What is being tested?
The trial tests if growth hormone (GH) improves cognitive functions in these athletes compared to a placebo. Participants are randomly assigned to receive either GH or placebo without knowing which they're getting. After this phase ends, there's an open-label extension where everyone knows they're receiving GH.
What are the potential side effects?
Possible side effects of growth hormone therapy include joint pain, swelling due to fluid in the body's tissues (edema), carpal tunnel syndrome-like symptoms such as numbness and tingling of the hands and fingers, muscle pain and increased cholesterol levels.
