Dr. Arvid Carlsson, a Swedish scientist whose discoveries about the brain led to the development of drugs for Parkinson’s disease and earned him a Nobel Prize, died on Friday. He was 95.................
................In his later years, Dr. Carlsson was an outspoken critic of fluoridating water supplies to prevent cavities. He said that fluoride produces side effects, such as mottled teeth, and that fluoridation was contrary to the principles of modern pharmacology because there was no way to regulate the amount of fluoride individuals received. He argued that individualized preventive care was a better approach.
