Attention-Deficit Hyperactivity Disorder
Attention-Deficit Hyperactivity Disorder is a disorder that affects large number of people.ADH, according to studies, have shown that boys are three times as likely to develop this disorder.Boys, scientific believe, are generally more prone to disorders of the nervous systems. Although the the onset can vary, specific behaviors that are typical of ADHD. usually arise between the ages of three and five. Studies estimate that between 2 and 9.5 percent of people worldwide of school age children have ADHD. Attention-Deficit Hyperactivity Disorder does not discriminate. Researchers have identified this disorder in every nation and in every culture. This disorder was once thought that children would out grow it. Researcher from the 1970`s show that about two thirds of 158 children with ADHD still showed tyoical patterns behaviors well into their twienties. Reasercher also show that those in the studies who no longer fit the description were having adjustment problems at work, ! Psychiatrists, since the early 1940`s have put several different labels on those whom are afflicted with Attention-Deficit. Some of these labels are as follows: ``minimal brain dysfunction,`` ``brain injured child syndrome,`
Rapoport and their collegues at the National Institute of Mental Health, in a 1996 study, have found that these two parts of the brain that regulate attention. Children are not able to learn as much because of the inability to have an appropriate attention span. Also exposure to high levels of lead during early childhood and brain injuries are non-genetic factors. These non-genetic factors account for 20 percent of boys afflicted with ADHD and less in girls. 526 identical twins and 389 fraternal twins were studied. The preffrontal cortex in the cerebellum and the basal ganglia with several clusters of nerve cells has been identified. It affects the lives of not only the children and adults afflicted, but also all those whom they come in contact with. He goes on to suggest that increasing the external use of prompts and cues about rules and time! interval should be strongely enforced. Studies to determine the reason why these brain areas to be smaller are still going on. Sundet of the University of Oslo together with Jim Stevenson of the University of Southamptom in England conducted one of the largest twin studies of ADHD. They went on to conclude that 80 percent of teh differences in attention, hyperactivity and impulsiveness between groups were explain by genetic factors. Studies show that this drug have been found to improve behavior in up to 90 percent of children afflicted with Attention- Deficit Hyperactivity Disorder older than five. Although no one knows the exact cause of Attention-Deficit Hyperactivity Disorder some theories have been explred. Although there is no cure for Attention-Deficit Hyperactivity Disorder there are ways to help people cope and manage with this disorder. It also causes problems because these children become too bossy when playing with other child with ADHA finds himself or herself playing alone.
