Lead researcher Dr. Phillip Shaw said, "If you have a certain variant of this gene, you have a greatly increased risk of having ADHD." In the second study, scientists found that ADHD is associated with lowered dopamine production. ADHD is a real disease, which can not be cured but only treated. According to Journal of Child and Adolescent Psychopharmacrology, scientist recorded a study after conducting research on the long usage of IR-MPH, which they found children who took the 10 month trial of the medicine showed decreased signs of ADHD symptoms. Jeffrey Newcorn’s scholarly journal about Pychopharmacrologic Tretment recognizes methylphenidate and detroamphetamine as both good medicines to help control the symptoms of ADHD.
Grilly had found people with Parkinson’s disease (low levels of dopamine) who were taking the drug L-dopa to raise their levels of dopamine were developing schizophrenic type symptoms. There is a flaw with one of the key pieces of evidence to support the dopamine hypothesis. The drugs used to treat schizophrenia by blocking the dopamine receptors can actually increases it as neurons struggle to compensate for the sudden deficiency. Haracz, in a review of post-mortem studies of schizophrenics, found that most of those studied who showed elevated dopamine levels had received antipsychotic drugs shortly before death, unlike post-mortem of schizophrenics who hadn’t received medication these results showed that these individuals had normal levels of dopamine. Therefore, this evidence then in fact weakens the support for the dopamine hypothesis.
Beyond the science of pharmaceuticals is the science of care, a role which encompasses how pills affect our physiology. Critics argue that were placebos to be encouraged in the practice of medicine, patients could delay other treatments with longer- lasting benefits. Similar to the placebo effect, in which a fake medication can give patients the benefits of having taken the real drug, the nocebo effect is the little-studied fact that patients taking a fake drug can also experience real negative side effects. "In one remarkable case, a participant in an antidepressant drug trial was given placebo tablets—and then swallowed 26 of them in a suicide attempt. Even though the tablets were harmless, the participant's blood pressure dropped perilously low."
When larger amounts of quinine are consumed, it can constitute a health problem for some consumer groups. BfR sees risks in particular for quinine intakes during pregnancy. For instance, a newborn baby, whose mother had drunk more than 1 litre tonic water a day in the weeks up to its birth, suffered health disorders. Based on existing regulations in the medicinal product sector, BfR, therefore, advises pregnant women against drinking quinine-containing beverages on precautionary grounds. People who have been advised against taking quinine, cinchona bark or their preparations by their doctors because of their clinical pictures should not consume any quinine-containing soft drinks either.
According to Schull’s drug handbook (2006), Phytonadione acts on the liver to promote the production of active prothrombin, proconvertin, plasma thromboplastin component, and Stuart factor. In other words, it promotes blood clotting. The safe dose for neonate is 0.5 to 1 mg injected intramuscularly within one hour of birth. Adverse reactions include: hyperbilirubinemia, pain, swelling, tenderness at injection site, and anaphylactoid reactions. Because neonates in the first few hours of life usually don’t have adequate vitamin K in their blood stream, physician often prescribes Phytonadione to prevent hemorrhaging of the newborn.
In this essay I will examine how smoking, alcohol and the mother’s diet influence prenatal development. Cigarette smoking is proven to have a negative effect on the smoker so how could it be any different for a fetus exposed to nicotine. Researchers have found that smoking and drinking are associated with disturbances in the placental functioning and with changes in maternal physiology that lead to oxygen deprivation and may produce structural and functional changes in the brain of a fetus ( Mavis Hetherington & Ross Parke). Mothers that smoke have a higher increase of infants being born with growth deficiencies rather than non-smokers. Also common with maternal smoking is Sudden Infant Death Syndrom (SIDS).
Children, Asthma and Secondhand Smoke Introduction * A. Audience Hook 1. Approximately 774,000 ER visits were related to asthma in 2009 (American Lung Association, 2013) * An estimated 400,000 to 1 million children have their condition worsened by exposure to secondhand smoke. (American Lung Association, 2013) B. Thesis statement a. Research suggests that asthmatic children should not be exposed to environmental tobacco smoke because asthma is a chronic and sometimes life-threatening disease and children with asthma can have their condition worsened by exposure to environmental tobacco smoke.
While many people believe that marijuana may not be as harmful as these other drugs, it can still affect the infant in a few ways. The baby can have physical problems; for example low birth weight and/or a small head. Developmentally, the child may experience difficulty with memory or attention, depression, and/or inadequate problem-solving skills (Berk, 2008, p. 67). Tobacco and alcohol are two of the most common and harmful teratogens which affect an unborn baby’s growth. Extensive alcohol consumption during pregnancy can lead to a very detrimental and potentially fatal disorder known as fetal alcohol syndrome.
Assignment 3 Social factors that affect human health and drugs P5 2) The social implications of a friend taking drugs are, he might lose his job, he might steal goods or money to pay for his drug addiction, another scenario is losing family and friends through antisocial behaviour. If he or she is pregnant, giving birth to a low birth- weight baby who also has a dependence on the drug. However it is a risk of an early death due to suicide, infections or an overdose. 3) One mechanism that can maintain optimal health is the nervous system. The normal body temperature is (37 c) and it doesn’t usually change by more than (1-2) c the body works to keep the temperature at (37 c) using homeostasis, regulation of temperature, or thermoregulation, also involves the nervous system.
Certain mascara brands contain mercury. Mercury can harm the body by causing anything from skin reactions to neurotoxicity issues. Also, most mascara contains bronopol, and in vast amounts, can eventually cause blindness (Hartmantell). Out of thirty-three brands of lipsticks, sixty-one percent contained lead (Malkan). Lead is a neurotoxin and when exposed to the body for long periods of time it can cause health issues such as “lowered IQ, reduced school performance, and increased aggression” (Gavin).
