I was researching damage to the hippocampus, (see hippocampus on Wiki or equal),& found that many of the disease states listed from ADD to Alzheimers are very prevalent in society & many of the drugs prescribed for treatment contain in one form or another fluoride. Approximately 1500 antidepressants contain fluoride. A friend was prescribed a compound of cortisone cream for dermatitis which contained fluoride. Its everywhere folks, & its earlier use goes all the way back to guess who, Hitler. There are a few states that do not use fluoride in their drinking water & Hawaii as of 2-yrs ago was voting to remove its use from their water.
