»Laughing and being happy - for healthy people this is normal. During my TPS® treatments, I notice that this is no longer normal for my patients. Many are sad and seem withdrawn. This is understandable when you can no longer do things the way you used to. I am all the more pleased when relatives call me after the first TPS® treatments with the NEUROLITH® or write to me that their loved ones are now happier again and that they are smiling more often.
