Mental Retardation https://greenmedinfo.com/taxonomy/term/3244/all en A meta-analysis reveals that thimerosal containing vaccines significantly increase the risk of neurodevelopmental disorders. https://greenmedinfo.com/article/meta-analysis-reveals-thimerosal-containing-vaccines-significantly-increase-ri BACKGROUND: Thimerosal is an ethylmercury-containing compound (49.6% mercury by weight) used as at the preservative level in vaccines (0.005% to 0.01%). METHODS: Statistical modeling in a meta-analysis epidemiological assessment of the Vaccine Adverse Event Reporting System (VAERS) for neurodevelopment disorders (NDs) reported following Diphtheria-Tetanus-whole-cell-Pertussis (DTP) vaccines in comparison to Diphtheria-Tetanus-whole-cell-Pertussis-Haemophilus Influenzae Type b (DTPH) vaccines (administered: 1994-1997) and following Thimerosal-containing Diphtheria-Tetanus-acellular-Pertussis (DTaP), vaccines in comparison to Thimerosal-free DTaP vaccines (administered: 1997-2000), was undertaken. RESULTS: Significantly increased adjusted (sex, age, vaccine type, vaccine manufacturer) risks of autism, speech disorders, mental retardation, personality disorders, thinking abnormalities, ataxia, and NDs in general, with minimal systematic error or confounding, were associated with TCV exposure. CONCLUSION: It is clear from the results of the present epidemiological study and other recently published data associating mercury exposure with childhood NDs, additional ND research should be undertaken in the context of evaluating mercury-associated exposures, especially from Thimerosal-containing vaccines.

Abstract:  OBJECTIVE: To observe the effect of acupuncture on intelligence quotient (IQ) in children with mental retardation (MR).METHODS: One hundred children with MR were randomly divided into an acupuncture group and a control group, 50 in each. There were 37 and 36 cases with complete data in the former and latter group respectively. Four-week treatment constituted a course, the comprehensive therapeutic effect of two groups was compared after 3 courses of treatment, and the influence of acupuncture on IQ was estimated.RESULTS: The total effective rate in the acupuncture group was 78.4%, better than 30.56% in the control group, the difference being significant (P https://greenmedinfo.com/article/acupuncture-improves-intelligence-children-mental-retardation#comments Intelligence Quotient (IQ): Low/Impaired Mental Retardation Acupuncture Human Study Fri, 21 Jan 2011 16:50:35 +0000 greenmedinfo 60301 at https://greenmedinfo.com Congenital hypothyroidism and mental retardation may be linked to iodine and trace mineral deficiencies. https://greenmedinfo.com/article/congenital-hypothyroidism-and-mental-retardation-may-be-linked-iodine-and-trac PMID:  Sante. 2007 Jan-Mar;17(1):41-50. PMID: 17897901 Abstract Title:  [Reflections on mental retardation and congenital hypothyroidism: effects of trace mineral deficiencies]. Abstract:  While deficiencies of trace minerals and vitamins are rare in humans eating a variety of food, they can occur in premature infants and those with disturbances in dietary behavior for physical or psychological reasons and during parenteral or enteral nutrition. Some deficiencies - such as iron and iodine - cause such serious specific disorders that they must be considered separately. Congenital hypothyroidism induced by iodine deficiency is a major problem. Its public health importance comes from the neurological complications that lead to the most severe forms of endemic congenital hypothyroidism (cretinism). In areas without iodine deficiency, the standard incidence of this disease in the West is 1/4,500 live births. In areas with iodine deficiency, however, its incidence varies from 1 to 5%! It is nonetheless underestimated, because the screening methods revolutionized 20 years ago are still not applied systematically. Additional factors include the thiocyanates in cassava, the selenium deficiency resulting in selenium-dependent glutathione peroxidase deficiency, and the natural goitrogens in some foods: milk, millet, walnuts, and bacterial and chemical water pollutants. Adolescents and adults need 100 microg/day, children aged 1-10 years 60-100 microg, and babies under one year, 35-40 microg, but these daily requirements are not necessarily met. This threat weighs on a billion people, 50-100 million in Europe, especially pregnant women, fetuses, newborns, and young children whose cerebral development may be negatively affected in the womb and in early life. According to some authors, subjects with cretinism syndrome should be found in places where goiter prevalence exceeds 20%. Evaluation of diffuse intellectual impairment in the population would require tools too specific for most studies. Generations of children are the victims throughout wide swaths of the African ecosystem in which it is endemic and associated with poor adaptation to the environment. But studies of isolated places cannot be transposed to entire populations. Because pregnancy in women with hypothyroidism is often thought to have a very negative prognosis, the two cases we report merit attention. In one case, despite certainly insufficient thyroid hormone replacement treatment, the child was born alive and healthy. In the second case, where hypothyroidism followed a thyroidectomy in a woman with Graves disease, a hydrocephalic child was liveborn, without any replacement treatment. In her next pregnancy, she received optimal hormonal treatment and delivered a healthy liveborn child. The disorders due to severe iodine deficiency did not affect our two patients. In a series of 166 cases of congenital hypothyroidism in newborns, only two cases had maternal antithyroid antibodies. Elsewhere, 9 women with hypothyroidism had 11 pregnancies, 9 normal children, 1 premature child (mother had eclampsia), and 1 with Down syndrome and an Ostium primum defect (mother aged 41 years). Ontogenesis of the hypothalamo-pituitary-thyroid axis of the fetus still appears today to develop independently of the mother in cases of hypothyroidism. An important role is played by type III deiodinase, which is especially active in the placenta during pregnancy, probably involving the T3 activity on nuclear and also mitochondrial receptors. The maturation of these receptors is not well understood. https://greenmedinfo.com/article/congenital-hypothyroidism-and-mental-retardation-may-be-linked-iodine-and-trac#comments Hypothyroidism Iodine Deficiency Mental Retardation Anti-Inflammatory Agents Diseases that are Linked Human Study Tue, 23 Mar 2010 17:04:47 +0000 greenmedinfo 53528 at https://greenmedinfo.com Rates of autism, speech disorders, mental retardation, infantile spasms, and thinking abnormalities were higher in children exposured to higher thimerosal levels. https://greenmedinfo.com/article/rates-autism-speech-disorders-mental-retardation-infantile-spasms-and-thinking PMID:  J Toxicol Environ Health A. 2006 Aug;69(15):1481-95. PMID: 16766480 Abstract Title:  An evaluation of the effects of thimerosal on neurodevelopmental disorders reported following DTP and Hib vaccines in comparison to DTPH vaccine in the United States. Abstract:  Thimerosal is an ethylmercury (49.55% mercury by weight) preservative historically added to some vaccines. Toxicokinetic studies showed children in the United States received doses of mercury from Thimerosal-containing vaccines (TCVs) in excess of safety guidelines. In the United States during the 1990s, diphtheria-tetanus-pertussis (DTP) and Haemophilus influenzae type b (Hib) vaccines (maximally, 50 mug mercury per joint administration) and diphtheria-tetanus-pertussis-Haemophilus influenzae type b (DTPH) vaccines (25 mug mercury per administration) were given to children in the same childhood vaccination schedule at 2, 4, 6, and 15-18 mo, so that children receiving DTP and Hib vaccines may have maximally received an additional 100 mug more mercury exposure from TCVs than children administered DTPH vaccines. A case-control epidemiological study of neurodevelopmental disorders (NDs) reported to the Vaccine Adverse Event Reporting System (VAERS) (online public access version; updated 31 August 2004) following administration of DTP vaccines in comparison DTPH vaccines manufactured by Lederle Laboratories (Pearl River, NY) from 1994 through 1998 was undertaken. Significantly increased odds ratios for autism, speech disorders, mental retardation, infantile spasms, and thinking abnormalities reported to VAERS were found following DTP vaccines in comparison to DTPH vaccines with minimal bias or systematic error. Additional ND research should be undertaken in the context of evaluating mercury-associated exposures, especially since in 2005 the Institute of Medicine issued a report calling into question handling of vaccine safety data by the National Immunization Program of the Centers for Disease Control and Prevention. https://greenmedinfo.com/article/rates-autism-speech-disorders-mental-retardation-infantile-spasms-and-thinking#comments Autism Cognitive Decline/Dysfunction Infantile Spasms Mental Retardation Neurodevelopmental Disorders Neurotoxic Thimerosal Meta Analysis Thu, 06 Jan 2011 23:31:25 +0000 greenmedinfo 60146 at https://greenmedinfo.com Retardation: Mental https://greenmedinfo.com/disease/retardation-mental <div class="field field-image"> <div class="field-items"> <div class="field-item odd"> <img class="imagefield imagefield-field_image" width="450" height="193" alt="" src="//cdn.greenmedinfo.com/sites/default/files/MentallyChallenged_0.jpg?1486067897" /> </div> </div> </div> <div class="field field-copyright"> <div class="field-items"> <div class="field-item odd"> Copyright: &lt;a href=&#039;http://www.123rf.com/profile_bakhtiarzein&#039;&gt;bakhtiarzein / 123RF Stock Photo&lt;/a&gt; </div> </div> </div> <fieldset class="fieldgroup group-facebook-like-info"><legend>Facebook Like Info</legend><div class="field field-facebook-total-count"> <div class="field-items"> <div class="field-item odd"> 0 </div> </div> </div> </fieldset> Mental Retardation Tue, 14 Apr 2009 07:25:34 +0000 greenmedinfo 21837 at https://greenmedinfo.com There is an association between neurodevelopmental disorders and thimerosal-containing vaccines. https://greenmedinfo.com/article/there-association-between-neurodevelopmental-disorders-and-thimerosal-containi PMID:  Exp Biol Med (Maywood). 2003 Jun;228(6):660-4. PMID: 12773696 Abstract Title:  Neurodevelopmental disorders after thimerosal-containing vaccines: a brief communication. Abstract:  We were initially highly skeptical that differences in the concentrations of thimerosal in vaccines would have any effect on the incidence rate of neurodevelopmental disorders after childhood immunization. This study presents the first epidemiologic evidence, based upon tens of millions of doses of vaccine administered in the United States, that associates increasing thimerosal from vaccines with neurodevelopmental disorders. Specifically, an analysis of the Vaccine Adverse Events Reporting System (VAERS) database showed statistical increases in the incidence rate of autism (relative risk [RR] = 6.0), mental retardation (RR = 6.1), and speech disorders (RR = 2.2) after thimerosal-containing diphtheria, tetanus, and acellular pertussis (DTaP) vaccines in comparison with thimerosal-free DTaP vaccines. The male/female ratio indicated that autism (17) and speech disorders (2.3) were reported more in males than females after thimerosal-containing DTaP vaccines, whereas mental retardation (1.2) was more evenly reported among male and female vaccine recipients. Controls were employed to determine if biases were present in the data, but none were found. It was determined that overall adverse reactions were reported in similar-aged populations after thimerosal-containing DTaP (2.4 +/- 3.2 years old) and thimerosal-free DTaP (2.1 +/- 2.8 years old) vaccinations. Acute control adverse reactions such as deaths (RR = 1.0), vasculitis (RR = 1.2), seizures (RR = 1.6), ED visits (RR = 1.4), total adverse reactions (RR = 1.4), and gastroenteritis (RR = 1.1) were reported similarly after thimerosal-containing and thimerosal-free DTaP vaccines. An association between neurodevelopmental disorders and thimerosal-containing DTaP vaccines was found, but additional studies should be conducted to confirm and extend this study. https://greenmedinfo.com/article/there-association-between-neurodevelopmental-disorders-and-thimerosal-containi#comments Autism Mental Retardation Neurodevelopmental Disorders Thimerosal Human Study Tue, 03 Aug 2010 02:01:47 +0000 greenmedinfo 55875 at https://greenmedinfo.com Vaccines and flu shots containing mercury may contribute to severe neurological diseases and/or death in children. https://greenmedinfo.com/article/vaccines-and-flu-shots-containing-mercury-may-contribute-severe-neurological-d PMID:  J Pediatr. 2009 Apr;154(4):514-520.e4. Epub 2008 Dec 3. PMID: 19205900 Abstract Title:  Are toxic biometals destroying your children&#039;s future? Abstract:  Cadmium, arsenic, lead, and mercury have been linked to autism, attention deficit disorder, mental retardation and death of children. Mercury in thimerosal found in many vaccines and flu shots contributes significantly to these problems. Decomposition of the thimerosal can produce more toxic compounds, either methylethylmercury or diethylmercury, in the body. These compounds have a toxicity level similar to dimethylmercury. Within the human body, a mitochondrial disorder may release the more toxic form of mercury internally. Young children and pregnant women must minimize internal exposure to the vaccines and flu shots containing mercury. https://greenmedinfo.com/article/vaccines-and-flu-shots-containing-mercury-may-contribute-severe-neurological-d#comments Attention Deficit Disorder Attention Deficit Disorder with Hyperactivity Autism Autism Spectrum Disorders Child Mortality Infant Mortality Mental Retardation Vaccine-induced Toxicity Vaccination: All Thimerosal Commentary Wed, 02 Sep 2009 01:28:36 +0000 greenmedinfo 46759 at https://greenmedinfo.com
