You’ve had multiple concussions in sport. Do you have

If so, you’re probably afraid that you may have the early signs of chronic traumatic encephalopathy (CTE) and that it’ll be downhill all the way with this incurable condition.

But maybe it’s not as bad as that?

There’s another common effect of repeated concussions that causes all these symptoms too, plus others such as reduced muscle-mass, baldness (in men), social isolation, a risk of fractures, extra weight around the waist and heart trouble. You could have growth hormone deficiency. The good news is this can be treated, often very effectively.

To test for it you need to take a stim test. This could be the insulin stress test, the glucagon stimulation test or the RHGH-arginine test. If the test shows you’re deficient, you will need regular growth hormone replacement, probably for life. Replacement has a good effect on energy, sleep, mood and motivation, and your ability to think and remember.

If you have difficulty getting an appropriate test, contact Christopher Lane Trust for information and support.
