Attention Deficit Hyperactivity Disorder or ADHD is a highly prevalent, neurobiological disorder which generally has an early onset of symptoms (Biederman, 2005). Children of both genders are affected and symptoms often persist into adolescence and adulthood. It often includes varying degrees of age-inappropriate behaviors such as impulsivity, inattention, and hyperactivity (Barkley, 2002). These behavior traits must be prominent enough to cause impairment in the individual’s functioning. ADHD is considered a developmentally relative deficit. This means that diagnosable ADHD cases are often the extreme cases of normal traits, or result from an abnormal delay in normal traits. Evidence exists that the disorder runs in families, and it is assumed to be heritable (Biederman, 2005). Polanczyk, Silva de Lima, Horta, Biederman, & Rohde (2007) point out that this disorder has become a major public health concern because of its prevalence, early onset, and the serious financial burden for both families and society, that is often associated with it. Common predicaments with ADHD include overdiagnosis, stimulant medications as treatment, and the issue regarding worldwide prevalence, namely, whether or not it is more common in the United States. Attention Deficit Hyperactivity Disorder has been studied extensively, often with controversial findings, which implies that much more research is necessary. ADHD appears quite diverse over varying cases, but the general signs and symptoms are similar. Biederman (2005) describes frequent personality traits such as distractibility, daydreaming, and difficulty focusing on single tasks for extended periods of time, as being the obvious signs of the inattention component of ADHD. The hyperactivity component is more obvious through behaviors such as excessive talking, restlessness, and…...

...31, 2012 Research Paper ADHD Medications and their Abuse Today The medications used to treat Attention Deficit-Hyperactivity Disorder (ADHD) are powerful, especially when abused, and have lasting impacts on the patients and the abusers. Treatment, in the form of prescription drugs is available to help these individuals, yet is harmful to others who either are misdiagnosed or abuse it. Additional laws and policies implemented by our elected officials will help ensure the prescribed medications reach the intended patients resulting in lower abuse. ADHD is described as the “most common neurological disorder” (“Facts”) and is a condition that affects many children and adults all over the world. The diagnosis and treatment for ADHD is on the rise in this country, and the signs and symptoms are important for people to notice. ADHD first appears in children who may show a combination of disruptive problems including impulsive behavior, low self-esteem, hyperactivity, and poor performance in school/work. Children, treated for this disorder, are more likely to carry it until adolescence, but for some, ADHD may become a life-long adjustment into adulthood. Specifically for males, hyperactivity is a huge signal that they need to be tested for attention deficit. For females, the signs are the opposite, leading to many underdiagnosed women. According to Centers for Disease Control and Prevention, “boys were more likely than girls to have ever been diagnosed with ADHD” (“Data”)...

...Do Schools and School Districts Recognize ADHD as a Learning Disability? Anne Smith University of California Riverside Do Schools and School Districts Recognize ADHD as a Learning Disability? A twelve year old boy named Mike, who fidgeted, played with small pieces of paper, paid more attention to events happening out the window then the paper on his desk. Mike has an IQ of 145, yet had a 2.4 grade point average. He could carry on intelligent, sophisticated conversations with adults who were engineers, teachers, veterinarians, and businessmen yet couldn’t pass an essay test on the book he read. His teachers and schools classified him as lazy. Let’s roll the clock forward twenty years, to another twelve year old boy named Orion, much like Mike; he too is classified as lazy, with an IQ of 139. Both boys were tested for learning disabilities and none were found but were diagnosed by psychiatrist and treated with medication for Attention Deficit Disorder with Hyperactivity (ADHD). It would seem that over the past twenty years little progress has been made in recognizing ADHD as a legitimate learning disorder. One can still ask the question ‘Do schools and school Districts recognize ADHD as a learning disability?’ Research bears out that they do not fully recognize ADHD as a true learning disability. Parents still must jump through many hoops to get the necessary educational help. ADHD is considered a “neurological glitch in......

...Matt Forster Benson, CA 3 3rd Hour Is ADHD Real of fake and can it be cured? If you ask anyone about ADD or ADHD, they’ll probably either have heard of it or have known of it. But not everyone has the same opinion on it and the medication prescribed for it. The diagnosis of this “mental disorder or disease” has become very prevalent in society, unlike 30 years ago when nobody had any idea of what it was. ADHD stands for, “Attention Deficit Hyper Disorder; ADHD or ADD are very similar. They are conditions in which sufferers generally appear restless or distracted and have difficulty focusing on even simple tasks. I believe that it is important that ADHD and ADD should be treated and eventually cured. The diagnosis of the disease is found by a psychiatrist. If the psychiatric doctor believes you have ADD or ADHD, he writes you a note for your doctor suggesting you be prescribed stimulants to help the patient focus better. Some Examples of the prescribed drugs for ADHD are Ritalin, which is the most common one, Adderall, Vyvance, and Dexedrine. These sets of stimulants are similar to amphetamine and cocaine. Responsible amounts are prescribed to the patients by the doctor. Most of the diagnoses are in children; because of this some doctors will not prescribe this medication for safety measures. The stimulants are very powerful drugs that could bear harmful results to younger constituents. The medications enhance cognitive learning and help when trying to study and......

...Attention Deficit Hyperactivity Disorder (ADHD) Attention Deficit Hyperactivity Disorder Have you ever known someone who struggles with being unorganized, unable to listen, have behavior problems or interrupts conversations frequently? Have you ever thought that their brain is wired a little differently? That question is the essence of ADHD. ADHD stands for Attention Deficit Hyperactivity Disorder. ADHD is defined as a “persistent pattern of inattention and / or hyperactivity-impulsivity that is more frequent and severe than is typically observed in individuals at a comparable level of development (APA, p. 78).” Since there is an abundance of information concerning this topic, this paper will focus on the nature and effects of ADHD, highlighting cognitive and genetic research, while taking into consideration the role of culture. Nature of ADHD The clinical history of the behavioral syndrome underlying the ADHD diagnosis can be traced back over 200 years in medical literature (Palmer and Finger, 2001). Currently, ADHD is a diagnosis formulated by the American Psychiatric Association (APA, 1994) on the basis of clinical criteria. The criteria describes chronic behavioral symptoms of inattention, impulsiveness and hyperactivity that are presented to a degree that significantly interfere with a person’s family and peer relations as well as their educational and or occupational functioning.

...Attention Deficit Hyperactive Disorder or more commonly known as ADHD is a disorder that is common in childhood that continues into adolescence. ADHD is a neurological disorder that affects how the brain receives, processes and responds to information (The National Center for Learning Disabilities, 2014). The main symptoms of ADHD include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (Brady). Many children suffer from ADHD without being diagnosed because the symptoms are different from child to child. There are three different categories of ADHD. These include predominantly hyperactive impulses, predominantly inattentive, and combined hyperactive-impulses and inattention (Brady). A child can be diagnosed with one of these three categories of ADHD depending on their specific symptoms but most children have a combination of hyperactive-impulses and inattention. The cause of ADHD is unknown but researchers are continually searching for answers. There are many different indications as to what causes ADHD such as genes, environmental factors and possibly the central nervous system (Mayo Clinic Staff, 2013). Several environmental factors have been identified as supposed risk factors for ADHD. In utero events such as maternal stress during pregnancy (Talge, Neal, & Glover, 2007), prenatal exposure to tobacco, alcohol and other drugs/environmental toxins, (Ribas-Fitó et al., 2006) (Pineda et a., 2007), pregnancy/birth......

...this and can use their creativity to come up with these strategies for teaching. Some strategies may not work, so instructors must put much thought into how they are going to accommodate to these particular students. A very common disorder in children is attention deficit hyperactivity disorder or ADHD. These students have a difficult time holding attention due to the lack of the ability to concentrate. These students tend to act impulsively, have attention deficits, and sometimes exude hyperactive behaviors. Children that have ADHD do not qualify for special education unless they also have another disability. Approximately 7.8 percent of children from the ages of 4 to 17 have been diagnosed with ADHD, research also shows that males are more likely to be diagnosed with ADHD over women. These ratios vary from 4:1 to 9:1. These students with ADHD can be impulsive, which means they act before they think or before considering the situation that they are currently in. They also have a hard time concentrating and find it difficult to sit still. There are medications for ADHD, and they are prescribed often, there are also a variety of drugs that have been proven to make a child with ADHD more attentive and improve their academic performance.

...Roark HCA/240 September 27th 2015 Kim Dankert ADHD is defined as attention deficit hyperactivity disorder. Individuals that have this disorder cannot keep their attention focused for very long, or on one particular subject for very long. Individuals can also be over active and very impulsive. The cause of this disorder has not been determined but there has been evidence that ADHD is a genetic disorder. ADHD use to be considered strictly ADD (attention deficit disorder), and it was once used to only describe school-aged children, but it is no longer considered a DSM diagnosis. In children, if they were hyper, they were considered ADHD, even if they really were not. Children can be hyper but not have this disorder. There are some misconceptions when it comes to ADHD. It is believed that ADHD is limited to only childhood. It has a chronic lifelong course and, if left untreated, results can be found in school and work failure, substance use disorders, legal difficulties, car accidents and fatalities. There are several different medications that have been used for treatment for this disorder. The most known medication is an oral medication called Ritalin.

...medical disorder called ADHD (attention deficit hyperactivity disorder). ADHD is a common behavioral disorder that affects school aged children. This percentage has increased from 7.8% in 2003. With this disorder increasing 3% per year, some begin to wonder if it is the children that are needing to be “fixed” or is it the way we teach our children. Are there alternatives to helping children with their focus other the medication? Medicating children due to ADHD is not always the answer and often alters the child’s personality. There are alternate teaching methods available for students before having them medicated. Teachers can perform these teaching methods to help children focus better in school and not get bored. Parents can help by also delivering these methods at home. Kids with ADHD may have trouble with focus, acting without thinking, hyperactivity and troubles knowing what is expected of them because they have a difficult time sitting and paying attention, so focusing on something is very difficult. The symptoms that they experience typically happen over a long period of time and do not just come in go like with children that just may be excited or anxious about something. There are no test that can diagnose ADHD. In order to evaluate the child a Dr. will meet with the child in the office as well as getting evaluations from the schools and from home to be sure that there are not issues at home that are causing the behaviors.

Do you imagine green, bloody, brain-eating monsters or small, skinny, sleep deprived children? In many cases this is what ADHD medicine turns many children into – zombie-like creatures. Stephanie’s daughter, Hannah, had always been a handful. Even as a preschooler, she would tear through the house like a tornado, shouting, roughhousing, and climbing on the furniture. Nothing seemed to have Hannah’s attention for very long. She would run away in the grocery store or in the mall. It was a full-time job parenting Hannah. Stephanie thought that her little girl was a normal child that got overly excited sometimes. Hannah’s second grade teacher began to notice how hard it was for her to calm Hannah down when she got too excited in class, so she talked to Stephanie about Hannah’s inattentiveness and disruptive behavior. “It was a struggle to get her to do simple tasks such as, homework, coloring, and brushing her teeth. She was so energetic and hyper all of the time. She couldn’t stay focused on anything for long. She would get annoyed and move on to the next thing that caught her attention,” Stephanie says. Her concerns lead her to Hannah’s pediatrician who recommended an evaluation for attention deficit hyperactivity disorder. ADHD is a common behavioral disorder that affects an estimated eight to ten percent of school-age children. Boys are about three......
