I. Mission of Newsletter:
This is a newsletter written for parents and professionals. This newsletter discusses the increasingly important topic of Attention Deficit Hyperactive Disorder (ADHD) among children. This newsletter will provide a brief background on ADHD including statistical data on ADHDs prevalence, the causes behind ADHD, diagnostic criteria, and a general summary of the medications used to treat the disorder. The primary focus of this newsletter is to portray the impact ADHD has on various aspects of a childs life including his or her psychological development, family and peer relations, and academic performance.
II. Statement of problem
ADHD is a neurologically based disorder characterized by inappropriate levels of three observable behaviors: inattention, impulsivity, and hyperactivity. (1)
ADHD is caused by a deficiency of a specific neurotransmitter (norepinephrine and/or its precursors, dopa and dopamine) in a specific set of brain circuits. Individuals with ADHD do not produce a sufficient amount of this neurotransmitter in particular areas of the brain, specifically areas which regulate attention, hyperactivity and impulse control. (2)
The Diagnostic criteria for ADHD are outlined in the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV; American Psychiatric Association, 1994). The DSM-IV identifies an inattention cluster and a hyperactivity-impulsivity cluster, each with nine symptoms. An individual must exhibit at least six of the nine behaviors in a symptom cluster to be considered significantly inattentive or hyperactive-impulsive. Symptoms must have appeared before age 7, been persistent for a minimum of 6 months, and must be exhibited in a degree that exceeds the normal developmental expectation of the behavior. (3)
DSM-IV Criteria for ADHD I. Either A or B:
A. Six or more of the following symptoms of inattention have been present for at least 6 months to a point that is disruptive and inappropriate for developmental level:
Inattention
1. Often does not give close attention to details or makes careless mistakes in schoolwork, work, or other activities.
2. Often has trouble keeping attention on tasks or play activities.
3. Often does not seem to listen when spoken to directly.
4. Often does not follow instructions and fails to finish schoolwork, chores, or duties in the workplace (not due to oppositional behavior or failure to understand instructions).
5. Often has trouble organizing activities.
6. Often avoids, dislikes, or doesn't want to do things that take a lot of mental effort for a long period of time (such as schoolwork or homework).
7. Often loses things needed for tasks and activities (e.g. toys, school assignments, pencils, books, or tools).
8. Is often easily distracted.
9. Is often forgetful in daily activities.
B. Six or more of the following symptoms of hyperactivity-impulsivity have been present for at least 6 months to an extent that is disruptive and inappropriate for developmental level:
Hyperactivity
1. Often fidgets with hands or feet or squirms in seat.
2. Often gets up from seat when remaining in seat is expected.
3. Often runs about or climbs when and where it is not appropriate (adolescents or adults may feel very restless).
4. Often has trouble playing or enjoying leisure activities quietly.
5. Is often "on the go" or often acts as if "driven by a motor".
6. Often talks excessively.
Impulsivity
1. Often blurts out answers before questions have been finished.
2. Often has trouble waiting one's turn.
3. Often interrupts or intrudes on others (e.g., butts into conversations or games).
II. Some symptoms that cause impairment were present before age 7 years.
III. Some impairment from the symptoms is present in two or more settings (e.g. at school/work and at home).
IV. There must be clear evidence of significant impairment in social, school, or work functioning.
V. The symptoms do not happen only during the course of a Pervasive Developmental Disorder, Schizophrenia, or other Psychotic Disorder. The symptoms are not better accounted for by another mental disorder (e.g. Mood Disorder, Anxiety Disorder, Dissociative Disorder, or a Personality Disorder).
Based on these criteria, three types of ADHD are identified:
1. ADHD, Combined Type: if both criteria 1A and 1B are met for the past 6 months
2. ADHD, Predominantly Inattentive Type: if criterion 1A is met but criterion 1B is not met for the past six months
ADHD, Predominantly Hyperactive-Impulsive Type: if Criterion 1B is met but Criterion 1A is not met for the past six months. (4)
American Psychiatric Association: Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision. Washington, DC, American Psychiatric Association, 2000.
Demographics: Attention Deficit Hyperactive Disorder (ADHD) is estimated to affect between 3 to 7 of every 100 school-aged children (5). ADHD is more frequently diagnosed in boys than girls, with ratios of 3:1 to 6:1 reported in the literature (Batsche & Knoff, 1994). However, the gender difference in actual diagnosis may be due to the differing symptom pattern between boys and girls, because girls are less likely to exhibit hyperactive and aggressive symptoms than are boys. Boys are also more likely to have comorbid oppositional defiant disorder and conduct disorder and may be referred at a higher rate because of the disruptive consequences of the comorbid disorders (Goldstein, 1996). Of children referred to clinics for ADHD, 50% to 80% will continue to have symptoms of the disorder into adolescence.(6)

In Focus
ADHD and Academic Performance:
ADHD symptoms make it very hard for a child to meet the demands of the school. The demands of the classroom are not congruent with the behaviors of an ADHD child. While in the classroom, children are expected to perform a number of responsibilities such as sit still in their seats and not distract other classmates, remain quiet until called on by the teacher, pay attention and stay focused, be organized, and abide by the rules. Low levels of dopamine in the brain makes control of impulse behavior almost impossible in the ADHD Children (7) therefore, an ADHD has a lot of difficulty only speaking when called on and not speaking out of turn or distracting others. The ADHD child may also be easily distracted by external stimuli (i.e. other children in the hall way or other outside cues) and he or she finds it very difficult to stay focused and listen to the teacher. In addition, the hyperactive component of the disorder may cause the child to be very fidgety or restless; it requires a lot of effort on the childs part to remain in his or her seat for the duration of the class period. Furthermore, low levels of Norepinephrine make it very difficult for ADHD children to sustain their focus on a task, plan ahead, and understand such concepts as sequence and time. (8) This may cause the child to be unable to start and complete a task (such as homework or in-class work). Also, because ADHD children have an impaired understanding of sequencing and time (9), it is very hard for them to manage their time effectively which can result in completing and handing in work late and problems sequencing can make it very difficult for a child to make and/or understand the transition to or connection between two events or activities.
ADHD children typically have many academic problems. Despite being intelligent, academic performance is below grade level. The best way to visualize this difficulty is to imagine an automobile with a Rolls Royce engine (the IQ/ability) and a go-cart transmission (attention/concentration system). The power of the engine is not getting to the wheels due to a difference in the transmission capability. Engine performance is only as powerful and efficient as the transmission system. (10)
These academic problems can also be due to a learning disability accompanied with ADHD. In addition to the already existing ADHD behavioral problems shown in the classroom, LDs can further exacerbate the risk of academic failure among ADHD children. Twenty to Thirty percent of patients with ADHD have a LD (11). Dr. Larry Silver describes LD as being caused by faulty wiring in the cortex of the brain. The result is difficulty-processing information. These processing problems might involve language, motor, cognitive, or executive functioning problems. LD makes the individual unable to learn in the normal way, requiring intervention strategies to learn how to learn.(12)
Research has shown that when exposed to a challenging task, ADHD boys display more frustration than do non-ADHD subjects and ADHD-boys tend to quit before completing the task. Furthermore, ADHD boys attribute their failures to external factors such as effort. ADHD boys make these external attributions because of their previous experiences with effort and failures; children with ADHD have learned that despite all of the effort they exert on an activity, they will not encounter success; they feel as though their control over their successes and failures is out of their hands. ADHD children have come to this conclusion most likely as a result of receiving negative feedback from people in their environment such as their teachers or parents. These adults may blame the ADHD child for not doing well enough as a result of not trying hard enough. Children with ADHD may consider effort to be a stable and uncontrollable characteristic of themselves. Thus, trying harder would not be a relevant consideration for these boys. (13)
A child with ADHD may encounter poor academic performance, despite the extended effort on behalf of the child to do well. This can be extremely frustrating for that child; this child may figure that no matter how hard he or she tries, it never amounts to acceptable results The failure experienced in school because of ADHD impacts a childs perspective on future achievement outcomes. This may lead the child to develop a helpless response to all challenging tasks.
The learned helplessness response due to academic struggles can also provoke the onset other psychological problems such as low self-esteem and depression among children.
Research has been developed which has suggested that ADHD children have negative self-perceptions of themselves and they experience high levels of depression compared to non-ADHD children.
In one study, researchers used the Self Perception Profile for Children to measure the following things among ADHD children: childrens scholastic competence, social acceptance, athletic competence, physical appearance, behavioral conduct, and global self-worth. How children rate themselves on these dimensions reflects how competent they believe themselves to be in each aspect of their life. The results show that, with the exception of athletic competence, ADHD children rate themselves as being lower on all levels of the other competencies listed. In other words, they view themselves to be less competent than other children without ADHD. (14)
Other studies have shown that children with ADHD display more symptoms of depression when compared to other non-ADHD children. For example, a study was conducted using 114 ADHD boys and 87 non-ADHD boys, all ages 7-12 years old. The results show that the ADHD boys reported experiencing more depressive symptoms than the control group (non-ADHD boys) as well as lower academic and social self-esteem (than control group), less general happiness accompanied by increased feelings of anxiety. (15)
ADHD and its affect on the Family
Hyperactive children can emotionally bankrupt a family. (16) ADHD is a pervasive disorder because it occurs across situations. The hyperactive, impulsive, inattentive and disruptive behaviors displayed at school are also seen in the home as well. The primary pattern of disruption involved the child with ADHD doing something that needed attention or that affected others.(17) This behavior soon erupts into more following disruptions as a result of having to live in this type environment. For example, because of their impulsive and uncontrollable behavior, children with ADHD demand much of, of not all of, the parents attention. Siblings may become jealous that the parents are devoting all of their energy to their brother or sister. As a result of this jealously, the sibling may imitate the maladaptive behavior displayed by the ADHD child, in hopes of obtaining the same response from their parents. Also, the siblings may deal with their jealousy by taking it out on the ADHD child, creating conflict among the children. Other disruptions include inter-familial conflicts and the breakdown of communication among family members with the replacement of more fighting, yelling, anger, guilt, and denial.
Research was conducted to study siblings responses to living with a brother with ADHD. Living with a brother or sister that has ADHD can be extremely exhausting for siblings. Disruptive ADHD behaviors influence three aspects of the siblings experiences. These aspects include victimization, care taking, and sorrow and loss.
Many siblings feel as though their well-being and safety are threatened by their ADHD sibling(s). In the home environment, their ADHD brothers or sisters victimize siblings of ADHD children; siblings are the ADHDs target for verbal as well as physical acts of aggression and abuse. Verbal abuse can include the use of threats and insults and physical abuse can include punching, kicking, hitting, etc. Siblings have to constantly be on guard; because the ADHD brother or sister is often impulsive, it is impossible to predict when he or she will act out. Siblings reported that their violent and aggressive interactions with their ADHD brothers was not characteristic of normal sibling rivalry. In addition, siblings reported that in response to the ADHD childs behavior, parents tended to downplay or neglected to acknowledge the severity of the aggressive acts.
Siblings often feel as though the ADHD child controls and manipulates the home environment as well as the family activities. It is often the case that family outings will be ruined or cut short because of the ADHD childs antisocial behavior. At home, most of the time, all of the focus is placed on the ADHD child and the other children tend to feel ignored. Siblings describe feeling expected to be somewhat invisible-not requiring too much help or attention from the parents. Parents often minimized their needs because they seemed so much less significant than those of an ADHD child. (18) Siblings become resentful towards their parents for not exerting enough control over the ADHD child and for not providing equal and fair treatment among all of the children.
Siblings are often required to bear the burden of taking care of their ADHD sibling. Parents expect the other children in the family to be a playmate and a babysitter for their ADHD sibling. For siblings, this responsibility can be very difficult because on one hand the siblings are expected to supervise their brother or sister while at the same time, the siblings are being subjected to verbal and physical abuse from their ADHD brother or sister. These siblings are caught in the middle-having to caretake and supervise very difficult children while at the same time being physically attacked, threatened, and controlled by them, all without having any power over the situation and little recognition for what the work entailed. (19)
Another study suggests that siblings of ADHD children are at risk for developing deficiencies in areas of psychiatric, neuropsychological and psychosocial functioning. ADHD children and their siblings (biological) were assessed at a baseline and 1 and 4 years later. In terms of psychiatric disorders, siblings of ADHD children, after 4 years, showed significantly high rates of ADHD, conduct disorder, oppositional defiant disorder, and multiple anxiety disorders. The high-risk siblings also scored more poorly on tests of achievement and showed significant evidence of school failure. High-risk siblings also displayed signs of poor social functioning, which is explained by low scores measuring School-Behavior, Spare-Time Problems, Boy-Girl relationships, and Problems with Parents. Overall, high-risk siblings showed more signs of psychosocial and psychiatric impairment compared to the non-ADHD siblings. (20)
ADHD and Peer Rejection:
Parents of children diagnosed with attention deficit / hyperactive disorder (ADHD) are nearly three times more likely to report that their child has difficulty getting along with neighborhood children, more than twice as likely to say their child gets picked on, and half as likely to believe that child has many good friends, than parents of children without ADHD. (21)
In general, children with ADHD often have difficulty with social interactions; they tend to be aggressive, domineering, impulsive, immature, overly talkative, and too intense. Furthermore, children with ADHD have been shown to have more specific deficits in their ability to participate, cooperate, and communicate with peers. Among preschoolers with ADHD, social cooperation skills seem to be the largest deficit area, whereas ADHD children with comorbid learning disabilities have difficulty perceiving nonverbal cues. It has also been suggested that both impulsivity and noncommunitative speech can lead to social problems for children with ADHD. (22)
Boys and Peer Rejection: Boys with ADHD frequently encounter peer rejection. In a study which compared social interactions amongst two subtypes of ADHD (predominantly inattentive type and ADHD combined type). Boys in both subgroups (ADHD PI and ADHD-CT) were generally not accepted by their peers; both groups received significantly lower social preference scores in the classroom. Boys with ADHD-combined type are more likely to be described by their classmates as someone who initiates arguments and fights. On the other hand, ADHD-Combined type boys are more likely to be described by their peers as being shy and socially withdrawn; also, boys within this subgroup are typically portrayed as being teased by and excluded by their classmates. (23)
One explanation for ADHD boys peer rejections may be the result of the child's inability to appropriately regulate his emotional states. Childrens management of emotional experiences has shown to be a crucial determinant of competent social functioning. It has been demonstrated that childrens negative emotionality and poor emotion regulation are implicated in the risk for social maladaptation. Children who are able to keep cool under emotionally arousing conditions are more likely to devise competent and peer-oriented solutions that enable interpersonal harmony and cooperation with the rules. In contrast, children who become over stimulated or who cope unconstructively with emotion tend to withdraw, disrupt play, or behave aggressively. (24) In this research study, boys with more-aggressive ADHD were unable to efficiently control their emotional state; in other words, when faced with an obstacle which prevented the achievement of a particular goal, more-aggressive ADHD boys maintained a high level of arousal because they concentrated on the obstacle in their path. This maintenance of high arousal inhibited these boys from devising another approach to solving the problem. In a cooperative classroom setting, this emotional response style might prompt them to disengage (i.e. shut down) or rebel against the demands (leading to non-compliance). (25)
Peer rejection among girls: Girls with ADHD have also been shown to be prone to peer rejection. Researchers observed ADHD girls and non-ADHD girls during the course of three summer programs. Each summer program lasted 5 weeks and during each session, the camp enlisted 75-80 girls (both ADHD and non-ADHD), ages 6 to 12 years. Observations from the study suggest that girls with ADHD have difficulty developing and maintaining any stable relationships. The study also suggests that the girls inability to make friends is in part due to several factors such as higher levels of conflict, relational aggression within the friendship and relational aggression to others. (26)
In another study, which observed the peer relationships between ADHD and non-ADHD girls, it was also concluded that girls with ADHD demonstrated more aggressive behavior patterns in comparison with non-ADHD girls. ADHD girls experienced more peer rejection. In addition, girls with ADHD exhibited more depressive and anxiety symptoms. (27)
