GDNF (Glial Derived Neurotrophic Factor) was discovered way back in 1993. In 2005, a study was carried out on human beings in Bristol, England, on 7 patients. One of those patients died from an unrelated heart problem but the condition of all the others managed to improve quite considerably. This story about GDNF has been on and off ever since 2005, with the manufacturers stopping manufacture of the GDNF and the stopping of all trials. Then pressure was brought to bear on the manufacturer to start producing the GDNF again and then new trials continued, but with no promising results so far.
In 2006, at the 1st World Parkinson's Congress, held in Washington DC, it was announced by Doctor Beth Fisher that human beings produce this GDNF, in the brain, when they do certain types of energetic exercise. The studies carried out by Dr Fisher proved that the condition of all those taking part improved considerably, due to the damage to the brain cells being repaired by the GDNF.
Why is it that neurologists are not telling us all about this GDNF. Why are they not telling us all to start doing regular hard walking, to produce this GDNF in our brains, which repairs the damaged brain cells and causes our condition to improve. Why are they carrying on with producing artificial GDNF - which then has to be implanted into the brain - when we could all be producing it naturally, by walking regularly? I think I know the answer to this question, but I will leave that to you to draw your own conclusions.
Have you heard about GDNF? Should it not be common knowledge by now?
