Certain aluminum compounds have been found to be an important component of the neurological damage characteristics of Alzheimer’s Disease (AD). Much research over the last decade has focused on the role of aluminum in the development of this disease. At this point, its role is still not clearly defined. Since AD is a chronic disease which may take a long time to develop, long-term exposure is the most important measure of intake. Long-term exposure is easiest to estimate for drinking water exposures. http://www.ehso.com/ehshome/alzheimers.htm

Dementia develops when the parts of the brain that are involved with learning, memory, decision-making, and language are affected by one or more of a variety of infections or diseases. The most common cause of dementia is Alzheimer’s disease, but there are as many as 50 other known causes. Most of these causes are very rare.

ALZHEIMER’S DISEASE AND DEMENTIA – IMPORTANT NEW STUDY SHOWS GRAVE IMPLICATIONS FROM INTERACTION OF ALUMINUM AND LOW DOSE FLUORIDE
The latest edition of the peer-reviewed medical journal, Brain Research, (vol.784:l998), reveals that aluminum-induced neural degeneration in rats is greatly enhanced when the animals were fed low doses of fluoride. The presence of fluoride enhanced the bio-availability of aluminum (Al) causing more aluminum to cross the blood-brain barrier and become deposited in the brain. The aluminum level in the brains of the fluoride-treated group was double that of the controls.

Fluoride, Dentists “Magic Bullet” is Shooting Blanks
SOURCE: New York State Coalition Opposed to Fluoridation, Inc.

Poor Not Helped; Money Wasted; Kids in Dental Pain; Viable Alternatives Shunned 
New York – January 20, 2012 — Despite decades of water fluoridation in New York State, the Journal of the American Dental Association reports that emergency treatment for NYS toddlers’ severe tooth decay has grown substantially in numbers and costs, many require general anesthesia, (1)reports the New York State Coalition Opposed to Fluoridation, Inc. (NYSCOF) 
Fluoridation is touted as an effective cavity preventive that will save money. But this study and others proves it’s doing neither. 
In 72% fluoridated NYS, 25,622 children, under six-years-old, made cavity-related emergency dental visits from 2004 though 2008. Visits grew from 4,361 in 2004 to 5,683 in 2008. Seventy-five percent required general anesthesia, up from 35% in 2004. Total costs: $121 Million ($18.5 million in 2004 increased to $31.3 million in 2008), most borne by taxpayers. 
“There is a limited number of dentists willing to treat patients younger than 6 and/or accept Medicaid” write the NYS researchers. 
More Statistics Show Fluoridation Fails New York State 
NYS Department of Health statistics reveal that, even when water is fluoridated, cavity-rates are extremely high in low-income third-graders. (2)

For example: 

• 85% of low-income third graders have tooth decay in WayneCounty(74% fluoridated)
• 83% in OntarioCounty(61% fluoridated)
• 82% in CayugaCounty(not fluoridated)
• 82% in AlleghenyCounty(14% fluoridated)
• 81% in LivingstonCounty(55% fluoridated)
• 67% in SchuylerCounty(not fluoridated)
• 58% in NassauCounty(not fluoridated) 

Fluoridation not only fails New York State but nationally children, the elderly and poor lack dental care.  The General Accounting Office estimates that 6.5 million children aged 2 through 18 in Medicaid had untreated tooth decay in 2005.(3) 
Oral health complications may be associated with adverse pregnancy outcomes, respiratory disease, cardiovascular disease, and diabetes. 
Annually, 164 million work hours and 51 million school hours are lost due to dental problems, according to the Institute of Medicine. (4)Also, a 2008 study of the armed forces reveals 52% of new recruits had oral health problems needing urgent attention, reports the Pew Charitable Trust.
“The American economy is hurt by dentists’ refusal to treat low-income Americans and by organized dentistry’s lobbying to outlaw cheaper dental care by viable dental professionals, such as dental therapists,” says attorney Paul Beeber, NYSCOF President. “Fluoridation is a false concept that must be abandoned.”
Past Studies Show that when fluoridation ceases so do cavities (5 )

• Cavity rates decreased six years after fluoridation was stopped in Kupio, Finland.
• Seven years after fluoridation ended in LaSalud, Cuba, cavity-free children increased dramatically
• Following the cessation of water fluoridation in the East German cities, Chemnitzand Plauen, a significant fall in caries prevalence was observed.
• After fluoridation ended in the East German cities, Spremberg and Zittau, cavities in 12-year-olds significantly decreased
• During an 11-month fluoridation break in Durham, NC,cavity rates remained stable but dental fluorosis declined in children born during that period
• In British Columbia, Canada, “the prevalence of caries decreased over time in the fluoridation-ended community while remaining unchanged in the fluoridated community.”
• In 1973, the Dutch town of Tielstopped fluoridation. Decayed, missing and filled surfaces dipped in 15-year-olds. Never-fluoridated Culemborg’s 15-year-olds had 72% less cavities over the same period.
