Attention Deficit Hyperactivity Disorder Three corresponding research areas for the brain are: perception, cognition, and action. Perception relates to the senses such as sight, sound, taste, smell, and touch. Cognition refers to how the brain processes information, and connects an emotional response to a certain problem or situation. Action is the outcome of what is observed from perception and understood from cognition. Any issue in these areas can lead to brain disorders. For instance, Autism is a disorder relating to cognition whereas Parkinson’s Disease relates to movement disabilities (Desimone 2007). Likwise, Attention Deficit Hyperactivity Disorder, more commonly referred to as ADHD, is a disorder, which causes a person to easily loose focus and/or be hyperactive. It is a common disorder that affects around 6.4 million American children (Holland and Riley 2014). …show more content…
The cortex is involved with thinking, perceiving, and language. Also for an individual with the disorder, the corpus callosum, which is responsible for connecting the right and left hemispheres of the brain, has defects (National Institutes of Health 2012). ADHD relates to genetics because it can be passed down through generations. In addition, individuals with the diagnosis show low levels of dopamine in the brain when compared to a normal functioning brain. Plus, certain children with ADHD have thin layer of brain tissue, which is gene related, however the tissue can grow as the child ages. This can cause a child’s symptoms to lower as well (Martin

It needs to be analyzed what is the root cause of this problem and what in the last few years has caused Attention Deficit Disorder or Attention Deficit hyperactivity disorder to rapidly become one of the most frequently observed disorder among children. Children are being observed at homes, schools and various vantage points to check whether they are suffering from such a disorder. Awareness is also increasing about the disorder in order to assist the children and their fa...
Dopamine gives a person the willingness, and attention span, to work; which means with higher levels of dopamine in synapses, the willingness to work is also higher. In a body with ADHD, the dopamine levels are substantially lower ...
Attention Deficit Hyperactivity Disorder (ADHD) is a developmental disorder that displays as distracted, hyperactive, and unable to focus on tasks and activities. Also known as Hyperkinetic Impulse Disorder, Hyperkinesis, Hyperactive Syndrome, Minimal Brain Damage, Minimal Brain Dysfunction, and Undifferentiated Deficit Disorder, ADHD is the most commonly diagnosed neurological disorder in children. Although many children with ADHD are quite intelligent, their lack of focus can frequently lead to poor grades and a low self esteem. The exact cause of ADHD is still unknown, but it is considered highly inheritable. Results from numerous international studies on twins have found that ADHD may have a genetic link. The occurrence of ADHD in one twin is more often mirrored an identical twin who has the same genetic makeup, then in a fraternal twin whose genetics are similar but not identical. It is also believed that if a parent, uncle, or grandparent had ADHD, it is more likely their family may develop it as well. No gene has been discovered that directly relates to the disorder. MRI studies comparing the brains of children with and without the condition have shown that children with ADHD have weaker brain activity in the frontal area of the brain when responding to tasks that require inhibition. Because of this, it is thought that ADHD affects certain sections of the frontal cortex, parietal lobe, and possibly parts of the cerebellum.
Attention-Deficit Hyperactivity Disorder (ADHD), once called hyperkinesis or minimal brain dysfunction, is one of the most common mental disorders among children. (Elia, Ambrosini, Rapoport, 1999) It affects 3 to 5 percent of all children, with approximately 60% to 80% of these children experiencing persistence of symptoms into adolescence and adulthood, causing a lifetime of frustrated dreams and emotional pain. There are two types of attention deficit hyperactivity disorder: an inattentive type and a combined type. The symptoms of ADHD can be classified into three categories: inattention, hyperactivity, and impulsivity. This behaviour stops ADHD sufferers from focussing deliberately on organising and completing a specific task that they may not enjoy, learning new skills or information is proved to be impossible. An example of such behaviour is recognised by the report written by the National Institute of Mental Health where one of the subjects under study was unable to pass schooling examinations due to her inattentive behaviour. Such behaviour can damage the person's relationships with others in addition to disrupting their daily life, consuming energy, and diminishing self-esteem. (National Institute of Mental Health 1999) There are also secondary symptoms which are associated with ADHD, such as learning disorders, anxiety, depression and other mood disorders, tic disorders, and conduct disorders. (Spencer, Biederman, and Wilens 1999 in Monastra V, Monastra D, George, 2002)

As such no single etiology has been identified for ADHD. ADHD is a heterogeneous condition currently thought to result from a complex interaction between the psychosocial stressors, environmental factors, neuro-chemical/ neuro-anatomical factors, familial and genetic factors.
Attention-Deficit/ Hyperactivity Disorder, otherwise known as ADHD, is the most common psychiatric condition effecting 9.5% of school-aged children in the United States (intuniv, 2013). If the disorder goes untreated, it will cause more long-term side effects and difficulties for the individual as an adult. Adults who have this condition face several adversities in every day life, such as impulsive behavior, low self-esteem and poor work performance. People are not aware of the complications that come with ADHD in adults. Not knowing the symptoms of the disease can cause people to not be sympathetic when they are interacting with someone with disorder.
The frontal lobe comprises a third of the brain and it enables us to engage in higher cognitive functions such as planning and problem solving (Jonides & Smith, 1999). The frontal lobe is divided into 3 regions, the motor cortex, premotor cortex, and prefrontal cortex. The motor cortex is located in the precentral gyrus and directs fine motor coordination. The premotor cortex is involved in planning, organizing, and integrating body movements. The prefrontal is involved in executive functions, including short-term memory, working memory, decision making, and prioritizing behaviors (Wilson, 2003). Some of the frontal lobe disorders than can cause brain damage and behavioral changes are Huntington’s disease, infection, stroke, tourettes, dementia, epilepsy, Parkinson’s disease, tumors, closed head injury and traumatic brain injury (Chow, 2000).
ADHD, or Attention deficit hyperactivity disorder, is one of the most common childhood disorders and can continue through adolescence and adulthood. There are many symptoms associated with ADHD but the most common include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity. Scientists are not exactly sure of what causes ADHD but they are more comfortable with the idea that a lot of different factors play a role in its development, such as, genes, environment, brain injuries, sugar, and food additives. The most widely used treatment is the drugs but this is not the only way to treat ADHD.
Historically, cognitive psychology was unified by an approach based on an resemblance between the mind and a computer, (Eysenck and Keane, 2010). Cognitive neuroscientists argue convincingly that we need to study the brain while people engage in cognitive tasks. Clearly, the internal processes involved in human cognition occur in the brain, and several sophisticated ways of studying the brain in action, including various imaging techniques, now exist, (Sternberg and Wagner, 1999, page 34).Neuroscience studies how the activity of the brain is correlated with cognitive operations, (Eysenck and Keane, 2010). On the other hand, cognitive neuropsychologists believe that we can draw general conclusions about the way in which the intact mind and brain work from mainly studying the behaviour of neurological patients rather than their physiology, (McCarthy and Warrington, 1990).
Do you know there is a medically diagnosed disorder that affects over two American children?” Experts on the subject say there are many more undiscovered cases out there and the cause is still unknown. It sounds like we have a really big problem. The thing is, the disorder that affects all these children, isn’t a disorder at all.
Before all else, the most important part to understand, about this disorder, is the symptoms that the suffer has. One of the most common symptoms of this disorder is inattentiveness. Inattentiveness is when a person is being heedless and is not focusing of paying attention to a matter being put in fron...
...evidence also showed that ADHD is polygenic with many different genes being involved. Yet, there is still confusion about the question which genes can be associated with ADHD. The contradicting findings suggest that ADHD is genetically complex and more molecular genetic studies are necessary to provide a more sophisticated account on the matter. Nevertheless, environmental factors seem to have a profound influence on the expression of the genes that cause ADHD. An evolutionary advantage of ADHD might exist, however the evidence points in a different direction. The provided studies showed that individuals diagnosed with ADHD were more likely to exhibit behavior that is not of much use to an academic environment and can lead to conflicts with the law enforcement, which might indicate that ADHD is in the view of a modern society clearly a disability with no upside.
