ADHD Children essays

ADHD Children essays In this day and age, drugs are being prescribed without hesitation. In fact, many of these drugs are being prescribed for children with various disorders. One of these disorders is called Attention Deficit Hyperactivity Disorder (ADHD). An estimated five to ten percent of children are diagnosed with this syndrome. One of the methods to treat this disorder is to use stimulants, specifically Ritalin. This method is controversial because it has many side effects and its long-term effects are unknown. It can also lead to addiction. Approximately two to three percent of elementary school children are taking some kind of stimulant to treat ADHD. Since so many children are taking this medication, new problems have arisen. Many of these children use these drugs in excessive amounts to get "high" with their friends. Some overdoses have even caused death. The alternative ways to treat this syndrome without medication are not adequately explored. Some doctors have found ways to combat this problem with little or no drugs. Why arent more doctors looking into these alternative methods? What kind of example is this excessive drug use setting for the children? Finally, what actions can be taken to solve this problem? Attention Deficit Hyperactivity Disorder (ADHD) is a syndrome caused by a biochemical imbalance and uniqueness. It has hundreds of symptoms that appear selectively in a certain children. Some of these symptoms include distractibility, confusion, faulty abstract thinking, inflexibility, poor verbal skills, aimlessness, perceptual difficulties, constant movement, varied rates of development, food cravings, allergies, and sleeping and coordination problems. The children have "little ability to block out noises in order to concentrate". Many qualities to look for in ADHD children are self-centeredness, impatience, recklessness, extreme emotionalism, and weak consciences. AD...

Cell Theory essays

Cell Theory essays Cell theory- all organisms are made of one or more cells and the products of those cells. An organism may be a single cell, such as a bacterium, or many cells organized to function together as in an animal or plant. In many celled organisms, there may be intercellular material made by the cells. All cells carry on life activities. The life activities of a many celled organism are the combined result of the activities of its individual cells. New cells only arrive from other living cells by the process of cell division. This is where the DNA is kept and RNA is transcribed. RNA is transported out of the nucleus through the nuclear pores. Proteins needed inside the nucleus are transported in through the nuclear pores. The nucleolus is usually visible as a dark spot in the nucleus (note the dark nucleolus in this electron microscope photo of a nucleus), and is the site of ribosome formation. Ribosomes are the sites of protein synthesis, where RNA is translated into protein. Protein synthesis is extremely important to cells, and so large numbers of ribosomes are found throughout cells (often numbering in the hundreds or thousands). Ribosomes exist floating freely in the cytoplasm, and also bound to the endoplasmic reticulum (ER). ER bound to ribosomes is called rough ER because the ribosomes appear as black dots on the ER in electron microscope photos, giving the ER a rough texture. These organelles are quite small, made up of 50 proteins and several long Ranks intricately bound together. Ribosomes have no membrane. Ribosomes disassemble into two subunits when not actively synthesizing protein. Mitochondria (singular: mitochondrion) are the sites of aerobic respiration, and generally are the major energy production center in eukaryotes. Mitochondria have two membranes, an inner and an outer, clearly visible in this electron microscope photo of a mitochondrion. Note the reticulations, or many enfolding, of the inner...
