Werbach, M.D. Senile dementia is a progressive degenerative brain disease associated with old age. Its symptoms include short-term memory loss, slowness in thought and movement, confusion, disorientation, depression, difficulty communicating, and loss of physical function. Alzheimer's disease accounts for about half of all senile dementia cases. Although there are many theories about what causes Alzheimer's, the fact is, its origins remain poorly understood. One theory proposed that the common occurrence of being exposed to aluminum could cause Alzheimer's dementia. Aluminum, the theory postulated, becomes concentrated in the characteristic lesions (senile plaques and neurofibrillary tangles) that develop in the brain during the course of the disease. At first, medical scientists thought this theory was absurd. Aluminum, they believed, accumulated merely as a result of a destructive process caused by some other factor. In recent years, however, the aluminum hypothesis has been gaining respect. For example, studies have discovered a direct association between the level of aluminum in municipal drinking water and the risk of Alzheimer's dementia. One study found aluminum in drinking water was related to only this specific type of dementia;1 another found that the probability of the association being due to chance was only 1 in 24, with a 46 percent increased risk for people drinking water with the highest aluminum levels.2 The use of aluminum-containing antiperspirants--but not the use of antiperspirants and deodorants in general--has also been associated with a risk of Alzheimer's dementia, with a trend toward a higher risk corresponding with increasing frequency of use.3 This relationship does not extend to aluminum-containing antacids,4 which may simply be evidence that the aluminum in antacids is not absorbed--the process of absorption through the gut mucosa is quite different from absorption through the skin. We also know that serum aluminum concentrations increase with age. Aluminum may accumulate slowly over our lifetimes or we may absorb it more easily as we age. Moreover, there is evidence that people with probable Alzheimer's disease have serum aluminum levels that are often significantly higher than those of people with other types of dementia, as well healthy people of similar ages.5 Further evidence that aluminum fosters the development of Alzheimer's dementia comes from a scientific (placebo-controlled) trial of desferrioxamine, a drug that removes aluminum from the body by binding with it. While regular administration of the drug failed to stop the disease from progressing, desferrioxamine did significantly reduce the rate of decline in the ability of a group of people with Alzheimer's dementia to care for themselves.6 Although the aluminum/Alzheimer's link remains unproven, I believe that waiting for definitive proof before taking a few easy and protective measures is foolhardy--and more scientists are starting to agree.7,8 Perhaps one person in 10 age 65 or older suffers from dementia; by age 80 that figure rises to one in five. This is too common an illness to ignore preventive measures until we can know for certain why it develops. Ways To Avoid Aluminum Here are my suggestions for minimizing your exposure to aluminum. * Drinking water should be low in aluminum. Some bottled-water companies provide an analysis of the aluminum content of their water. You might also find out from your public water company what the aluminum level is in the local drinking water. * Aluminum-containing antiperspirants can easily be avoided, as can aluminum utensils and even, to play it safe, aluminum-containing antacids. * Commercially processed foods such as cake and pancake mixes, frozen doughs and self-rising flour are sources of dietary aluminum, so their ingestion should be minimized. Watch for and avoid sodium aluminum phosphate, an ingredient in baking powder. Pickles and cheese should also be avoided. * There is a close relationship between silicon and aluminum in Alzheimer brain lesions, as the two substances bind together to form aluminosilicates.9 High levels of silica in drinking water in the form of silicic acid do seem to protect against the adverse effects of aluminum ingestion, and silicic acid ingestion increases urinary aluminum excretion.10,11 Whether silica supplements protect against the development of dementia has yet to be determined. * Besides minimizing aluminum exposure, taking the Recommended Dietary Allowance (RDA) of calcium, magnesium and zinc should help to protect against aluminum accumulation.12-14 Deficiencies of these important minerals are common among the elderly.15 Yet, unless there is laboratory evidence of a zinc deficiency, I would not recommend zinc supplementation to help prevent Alzheimer's disease, for two reasons. First, beta-amyloid protein, the major substance found in the brain lesions (usually in a liquid form), binds with zinc. At concentrations only slightly higher than those normally found in the brain, excess zinc may convert the protein to the solid form that is found in Alzheimer lesions.16 This suggests that, at least in theory, excess zinc could actually promote the development of the disease. Second, there is a lack of adequate research demonstrating the efficacy of zinc supplementation in preventing Alzheimer's, although in one study all six relatively young dementia victims had some memory improvement following supplementation with zinc aspartate.17 References 1.

But--you knew that. http://www.altcorp.com/DentalInforma...umvaccines.htm == Health Health Archives Vaccines show sinister side By pieta woolley Publish Date: 23-Mar-2006 If two dozen once-jittery mice at UBC are telling the truth postmortem, the world's governments may soon be facing one hell of a lawsuit. New, so-far-unpublished research led by Vancouver neuroscientist Chris Shaw shows a link between the aluminum hydroxide used in vaccines, and symptoms associated with Parkinson's, amyotrophic lateral sclerosis (ALS, or Lou Gehrig's disease), and Alzheimer's. Shaw is most surprised that the research for his paper hadn't been done before. For 80 years, doctors have injected patients with aluminum hydroxide, he said, an adjuvant that stimulates immune response. "This is suspicious," he told the Georgia Straight in a phone interview from his lab near Heather Street and West 12th Avenue. "Either this [link] is known by industry and it was never made public, or industry was never made to do these studies by Health Canada. I'm not sure which is scarier." Similar adjuvants are used in the following vaccines, according to Shaw's paper: hepatitis A and B, and the Pentacel cocktail, which vaccinates against diphtheria, pertussis, tetanus, polio, and a type of meningitis. To test the link theory, Shaw and his four-scientist team from UBC and Louisiana State University injected mice with the anthrax vaccine developed for the first Gulf War. Because Gulf War Syndrome looks a lot like ALS, Shaw explained, the neuroscientists had a chance to isolate a possible cause. All deployed troops were vaccinated with an aluminum hydroxide compound. Vaccinated troops who were not deployed to the Gulf developed similar symptoms at a similar rate, according to Shaw. After 20 weeks studying the mice, the team found statistically significant increases in anxiety (38 percent); memory deficits (41 times the errors as in the sample group); and an allergic skin reaction (20 percent). Tissue samples after the mice were "sacrificed" showed neurological cells were dying. Inside the mice's brains, in a part that controls movement, 35 percent of the cells were destroying themselves. "No one in my lab wants to get vaccinated," he said. "This totally creeped us out. We weren't out there to poke holes in vaccines. But all of a sudden, oh my God-we've got neuron death!" At the end of the paper, Shaw warns that "whether the risk of protection from a dreaded disease outweighs the risk of toxicity is a question that demands our urgent attention." He's not the only one considering that. The charge that there's a sinister side to magic bullets isn't new. With his pen blazing, celebrity journalist Robert F. Kennedy Jr. popularized vaccine scepticism with his article arguing that mercury in vaccines causes autism, which ran in the June 2005 Rolling Stone and on-line at Salon.com. So did last year's vaccines-linked-to- autism bestseller, Evidence of Harm by David Kirby (St. Martin's Press). But there's a potential public-health cost to all the controversy, according to the B.C. Centre for Disease Control. "Vaccines have been a victim of their own success," spokesperson Ian Roe told the Straight in a telephone interview from Ottawa. Diseases such as polio, which killed his father-in-law, are almost eradicated and therefore no longer serve as a warning to parents. But the epidemic threat is still real. "If everyone decided to not get vaccinated, we'd live in a very different world." Canada's last national immunization conference, in December 2004, heard a report that vaccine coverage is sometimes low. For diphtheria, the Public Health Agency of Canada found that just 75 percent of two-year-olds are immunized; the target is 99 percent. For tetanus, just 66 percent of 17-year-olds are immunized, compared to a target of 97 percent. Dr. Ronald Gold, the former head of the infectious-disease division at Toronto's Hospital for Sick Children, told the conference that "we will never be without an anti-vaccine movement," but "in reality, there is no scientific evidence for these myths." Shaw acknowledges that there's a lot of pressure on parents to vaccinate their children. "You're considered to be a really bad parent if you don't vaccinate," he said-and your child can't attend public school. "But I don't think the safety of vaccines is demarcated. How does a parent make a decision based on what's available? You can't make an intelligent decision." Conservatively, he said, if one percent of vaccinated humans develop ALS from vaccine adjuvants, it would still constitute a health emergency. It's possible, he said, that there are 10,000 studies that show aluminum hydroxide is safe for injections. But he hasn't been able to find any that look beyond the first few weeks of injection. If anyone has a study that shows something different, he said, please "put it on the table. That's how you do science." Neuroscience research is difficult, Shaw said, because symptoms can take years to manifest, so it's hard to prove what caused the symptoms. "To me, that calls for better testing, not blind faith." He pointed out that George W. Bush passed legislation that opens the door for the USA to order a nationwide anthrax immunization campaign, with the threat of bioterrorism. Shaw's paper is currently undergoing a peer review. http://www.straight.com/content.cfm?id=16717 == Safety of Aluminum Added to Vaccines as a Vaccine Adjuvant E-mail from Dr. Philip Rudnick Ph.D. Professor Emeritus, Chemistry West Chester University of Pennsylvania Date: Sun, 08 Dec 2002 15:08:06 -0500 From: To: Subject: Aluminum Neurotoxicity http://www.altcorp.com/TESTFoundation/thimelililly.htm Thimerosal is certainly a very potent neurotoxin.

Pharmacol Toxicol 1992 Apr;70(4):278-80. Aluminium-adjuvanted vaccines transiently increase aluminium levels in murine brain tissue. Division of Bacteriology, National Institute for Biological Standards and Control, Herts., UK. Aluminum is widely used as an adjuvant in human vaccines, and children can often receive up to 3.75 mg of parenteral aluminum during the first six months of life. We show that intraperitoneal injection of aluminum adsorbed vaccines into mice causes a transient rise in brain tissue aluminum levels peaking around the second and third day after injection. This rise is not seen in the saline control group of animals or with vaccine not containing aluminum. It is likely that aluminum is transported to the brain by the iron-binding protein transferrin and enters the brain via specific transferrin receptors.

To minimize reactions after immunization with DPT vaccine due to impurities in the toxoids, the use of toxoided purified toxins is suggested. Neurotoxicology of the brain barrier system: new implications. Zheng W. J Toxicol Clin Toxicol. 2001;39(7):711-9. College of Physicians and Surgeons, Columbia University, New York, New York 10032, USA. The concept of a barrier system in the brain has existed for nearly a century. The barrier that separates the blood from the cerebral interstitial fluid is defined as the blood-brain barrier, while the one that discontinues the circulation between the blood and cerebrospinal fluid is named the blood-cerebrospinal fluid barrier. Evidence in the past decades suggests that brain barriers are subject to toxic insults from neurotoxic chemicals circulating in blood. The aging process and some disease states render barriers more vulnerable to insults arising inside and outside the barriers. The implication of brain barriers in certain neurodegenerative diseases is compelling, although the contribution of chemical-induced barrier dysfunction in the etiology of any of these disorders remains poorly understood. This review examines what is currently understood about brain barrier systems in central nervous system disorders by focusing on chemical-induced neurotoxicities including those associated with nitrobenzenes, N-methyl-D-aspartate, cyclosporin A, pyridostigmine bromide, aluminum, lead, manganese, 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, and 3-nitropropionic acid. Contemporary research questions arising from this growing understanding show enormous promises for brain researchers, toxicologists, and clinicians. Aluminum, NO, and nerve growth factor neurotoxicity in cholinergic neurons. Szutowicz A. J Neurosci Res. 2001 Dec 1;66(5):1009-18. Chair of Clinical Biochemistry, Department of Laboratory Medicine, Medical University of GdaÅ"sk, Debinki 7, 80-211 GdaÅ"sk, Poland. Several neurotoxic compounds, including Al, NO, and beta-amyloid may contribute to the impairment or loss of brain cholinergic neurons in the course of various neurodegenerative diseases. Genotype and phenotypic modifications of cholinergic neurons may determine their variable functional competency and susceptibility to reported neurotoxic insults. Hybrid, immortalized SN56 cholinergic cells from mouse septum may serve as a model for in vitro cholinotoxicity studies. Differentiation by various combinations of cAMP, retinoic acid, and nerve growth factor may provide cells of different morphologic maturity as well as activities of acetylcholine and acetyl-CoA metabolism. In general, differentiated cells appear to be more susceptible to neurotoxic signals than the non-differentiated ones, as evidenced by loss of sprouting and connectivity, decreases in choline acetyltransferase and pyruvate dehydrogenase activities, disturbances in acetyl-CoA compartmentation and metabolism, insufficient or excessive acetylcholine release, as well as increased expression of apoptosis markers. Each neurotoxin impaired both acetylcholine and acetyl-CoA metabolism of these cells. Activation of p75 or trkA receptors made either acetyl-CoA or cholinergic metabolism more susceptible to neurotoxic influences, respectively. Neurotoxins aggravated detrimental effects of each other, particularly in differentiated cells. Thus brain cholinergic neurons might display a differential susceptibility to Al and other neurotoxins depending on their genotype or phenotype-dependent variability of the cholinergic and acetyl-CoA metabolism. Copyright 2001 Wiley-Liss, Inc. Aluminium impairs the glutamate-nitric oxide-cGMP pathway in cultured neurons and in rat brain in vivo: molecular mechanisms and implications for neuropathology. Canales JJ, Corbalan R, Montoliu C, Llansola M, Monfort P, Erceg S, Hernandez-Viadel M, Felipo V. J Inorg Biochem. 2001 Nov;87(1-2):63-9. Laboratory of Neurobiology, Instituto de Investigaciones Citológicas, Fundación Valenciana de Investigaciones Biomédicas, Amadeo de Saboya 4, 46010 Valencia, Spain. Aluminium (Al) is a neurotoxicant and appears as a possible etiological factor in Alzheimer's disease and other neurological disorders. The mechanisms of Al neurotoxicity are presently unclear but evidence has emerged suggesting that Al accumulation in the brain can alter neuronal signal transduction pathways associated with glutamate receptors. In cerebellar neurons in culture, long term-exposure to Al added 'in vitro' impaired the glutamate-nitric oxide (NO)-cyclic GMP (cGMP) pathway, reducing glutamate-induced activation of NO synthase and NO-induced activation of the cGMP generating enzyme, guanylate cyclase. Prenatal exposure to Al also affected strongly the function of the glutamate-NO-cGMP pathway. In cultured neurons from rats prenatally exposed to Al, we found reduced content of NO synthase and of guanylate cyclase, and a dramatic decrease in the ability of glutamate to increase cGMP formation. Activation of the glutamate-NO-cGMP pathway was also strongly impaired in cerebellum of rats chronically treated with Al, as assessed by in vivo brain microdialysis in freely moving rats. These findings suggest that the impairment of the Glu-NO-cGMP pathway in the brain may be responsible for some of the neurological alterations induced by Al. Effects of aluminium exposure on brain glutamate and GABA systems: an experimental study in rats. Nayak P, Chatterjee AK. Food Chem Toxicol. 2001 Dec;39(12):1285-9. Biochemistry and Nutrition Research Laboratory, Department of Physiology, University of Calcutta, 92 A.P.C. Road, 700 009, Calcutta, India. It has been postulated that the neurotoxic effects of aluminium could be mediated through glutamate, an excitatory amino acid. Hence the effects of aluminium administration (at a dose of 4.2mg/kg body weight daily as aluminium chloride, hexahydrate, intraperitoneally, for 4 weeks) on glutamate and gamma-amino butyrate (GABA), an inhibitory amino acid, and related enzyme activities in different regions of the brain were studied in albino rats. The glutamate level increased significantly in the cerebrum, thalamic area, midbrain-hippocampal region and cerebellum in response to in vivo aluminium exposure. The aluminium insult also caused significant increases in glutamate alpha-decarboxylase activity in all the brain regions. However, on aluminium insult, the GABA content was not significantly changed except in the thalamic area, where it was elevated. On the contrary, the GABA-T activities of all the regions were reduced significantly in all regions except the midbrain-hippocampal region. However, the succinic semi-aldehyde content of all brain regions increased, often significantly. The aluminium-induced modification of the enzyme activities may be either due to the direct impact of aluminium or due to aluminium-induced changes in the cellular environment. The aluminium-induced differential regional accumulation of glutamate or other alterations in enzymes of the glutamate-GABA system may be one of the causes of aluminium-induced neurotoxicity. Dementia in patients undergoing long-term dialysis: aetiology, differential diagnoses, epidemiology and management. Rob PM, Niederstadt C, Reusche E. CNS Drugs. 2001;15(9):691-9. Nephrologisches Zentrum am Klinikum Süd, Kalhlhorststrasse 31, D-23552 Lübeck, Germany. Dementia in patients undergoing long-term dialysis has not been clearly defined; however, four different entities have been described. Uraemic encephalopathy is a complication of uraemia and responds well to dialysis. Dialysis encephalopathy syndrome, the result of acute intoxication of aluminium caused by the use of an aluminium-containing dialysate, was a common occurrence prior to 1980. However, using modern techniques of water purification, such acute intoxication can now be avoided. Dialysis-associated encephalopathy/dementia (DAE) is always associated with elevated serum aluminium levels. Pathognomonic morphological changes in the brain have been described, but the mechanism for the entry of aluminium into the CNS is incompletely understood. The mechanisms involved in the pathogenesis of the neurotoxicity associated with aluminium are numerous. Although only a very small fraction of ingested aluminium is absorbed, the continuous oral aluminium intake from aluminium-based phosphate binders, and also of dietary or environmental origin, is responsible for aluminium overload in dialysis patients. Age-related dementia, especially vascular dementia, occurs in patients undergoing long-term dialysis as frequently as it does in the general population. The differential diagnoses of dialysis-associated dementias should include investigation for metabolic encephalopathies, heavy metal or trace element intoxications, and distinct structural neurological lesions such as subdural haematoma, normal pressure hydrocephalus, stroke and, particularly, hypertensive encephalopathy and multi-infarct dementia. To prevent DAE, dietary training programmes should aim to achieve the lowest phosphate intake and pharmacological tools should be used to keep serum phosphate levels below 2 mmol/L. To prevent vascular dementia, lifestyle modification should be undertaken, including optimal physical activity and fat intake, nicotine abstinence, and targeting optimal blood glucose, cholesterol and triglyceride levels, and blood pressure, to those outlined in current recommendations. The toxicology of aluminum in the brain: a review. Yokel RA. Neurotoxicology. 2000 Oct;21(5):813-28. College of Pharmacy and Graduate Center for Toxicology, University of Kentucky Medical Center, Lexington, USA. Aluminum is environmentally ubiquitous, providing human exposure. Usual human exposure is primarily dietary. The potential for significant Al absorption from the nasal cavity and direct distribution into the brain should be further investigated. Decreased renal function increases human risk of Al-induced accumulation and toxicity. Brain Al entry from blood may involve transferrin-receptor mediated endocytosis and a more rapid process transporting small molecular weight Al species. There appears to be Al efflux from the brain, probably as Al citrate. There is prolonged retention of a fraction of Al that enters the brain, suggesting the potential for accumulation with repeated exposure. Al is a neurotoxicant in animals and humans. It has been implicated in the etiology of sporadic Alzheimer's disease (AD) and other neurodegenerative disorders, although this is highly controversial. This controversy has not been resolved by epidemiological studies, as only some found a small association between increased incidence of dementia and drinking water Al concentration. Studies of brain Al in AD have not produced consistent findings and have not resolved the controversy. Injections of Al to animals produce behavioral, neuropathological and neurochemical changes that partially model AD. Aluminum has the ability to produce neurotoxicity by many mechanisms. Excess, insoluble amyloid beta protein (A beta) contributes to AD. Aluminum promotes formation and accumulation of insoluble A beta and hyperphosphorylated tau. To some extent, Al mimics the deficit of cortical cholinergic neurotransmission seen in AD. Al increases Fe-induced oxidative injury. The toxicity of Al to plants, aquatic life and humans may share common mechanisms, including disruption of the inositol phosphate system and Ca regulation. Facilitation of Fe-induced oxidative injury and disruption of basic cell processes may mediate primary molecular mechanisms of Al-induced neurotoxicity. Avoidance of Al exposure, when practical, seems prudent. Aluminum neurotoxicity in preterm infants receiving intravenous-feeding solutions. Bishop NJ, Morley R, Day JP, Lucas A. N Engl J Med. 1997 May 29;336(22):1557-61. Comment in: N Engl J Med. 1997 Oct 9;337(15):1090-1 PMID: 9324646 Medical Research Council (MRC) Dunn Nutrition Unit, Cambridge, United Kingdom. BACKGROUND: Aluminum, a contaminant of commercial intravenous-feeding solutions, is potentially neurotoxic. We investigated the effect of perinatal exposure to intravenous aluminum on the neurologic development of infants born prematurely. METHODS: We randomly assigned 227 premature infants with gestational ages of less than 34 weeks and birth weights of less than 1850 g who required intravenous feeding before they could begin enteral feeding to receive either standard or specially constituted, aluminum-depleted intravenous-feeding solutions. The neurologic development of the 182 surviving infants who could be tested was assessed by using the Bayley Scales of Infant Development at 18 months of age. RESULTS: The 90 infants who received the standard feeding solutions had a mean (+/-SD) Bayley Mental Development Index of 95+/-22, as compared with 98+/-20 for the 92 infants who received the aluminum-depleted solutions (P=0.39). In a planned subgroup analysis of infants in whom the duration of intravenous feeding exceeded the median and who did not have neuromotor impairment, the mean values for the Bayley Mental Development Index for the 39 infants who received the standard solutions and the 41 infants who received the aluminum-depleted solutions were 92+/-20 and 102+/-17, respectively (P=0.02). The former were significantly more likely (39 percent, vs. 17 percent of the latter group; P=0.03) to have a Mental Development Index of less than 85, increasing their risk of subsequent educational problems. For all 157 infants without neuromotor impairment, increasing aluminum exposure was associated with a reduction in the Mental Development Index (P=0.03), with an adjusted loss of one point per day of intravenous feeding for infants receiving the standard solutions. CONCLUSIONS: In preterm infants, prolonged intravenous feeding with solutions containing aluminum is associated with impaired neurologic development. == Of course you have never read * A Dragon by the Tail*................. http://www.hpakids.org/holistic-heal...Tail/print/183 Of course--you did.

The fact of the matter is that aluminum is in vaccines because it helps the vaccine work better. Jeff Prove it. http://www.nal.usda.gov/awic/pubs/antibody/overview.htm The FACT is Aluminum is an established neurotoxin. Further fact, you dismissed all studies that have been posted. You are a waste of time. Please show that the aluminum, in the doses used, is a neurotoxin or an unacceptable risk. Jeff |

"john" wrote in message ... "Jeff" wrote in message k.net... No child can escape poisons. Wrong again. Children can escape vaccine poisons by not being vaccinated. They also would have to not drink water, not eat cooked meat, not be around electric motors, not be in a city, etc. Sorry, but there are poisons in very small quantities all around us. The benefits of vaccinations greatly outweigh the risks. The so-called poisons are not toxic at the doses used and help the vaccines work better. Jeff |
