Attention deficit hyperactivity disorder
Attention deficit hyperactivity disorder (ADHD or AD/HD or ADD) is a developmental disorder. It is characterized primarily by "the co-existence of attentional problems and hyperactivity, with each behavior occurring infrequently alone" and symptoms starting before seven years of age.
ADHD is the most commonly studied and diagnosed psychiatric disorder in children, affecting about 3 to 5 percent of children globally and diagnosed in about 2 to 16 percent of school aged children.[5] It is a chronic disorder with 30 to 50 percent of those individuals diagnosed in childhood continuing to have symptoms into adulthood. Adolescents and adults with ADHD tend to develop coping mechanisms to compensate for some or all of their impairments. It is estimated that 4.7 percent of American adults live with ADHD. Standardized rating scales such as WHO's Adult ADHD Self-Report Scale can be used for ADHD screening and assessment of the disorder's symptoms' severity.
ADHD is diagnosed two to four times more frequently in boys than in girls, though studies suggest this discrepancy may be partially due to subjective bias of referring teachers. ADHD management usually involves some combination of medications, behavior modifications, lifestyle changes, and counseling. Its symptoms can be difficult to differentiate from other disorders, increasing the likelihood that the diagnosis of ADHD will be missed.[15] In addition, most clinicians have not received formal training in the assessment and treatment of ADHD, in particular in adult patients.
ADHD and its diagnosis and treatment have been considered controversial since the 1970s. The controversies have involved clinicians, teachers, policymakers, parents and the media. Topics include the actuality of the disorder, its causes, and the use of stimulant medications in its treatment. Most healthcare providers accept that ADHD is a genuine disorder with debate in the scientific community centering mainly around how it is diagnosed and treated. The American Medical Association concluded in 1998 that the diagnostic criteria for ADHD are based on extensive research and, if applied appropriately, lead to the diagnosis with high reliability.
Classification
ADHD may be seen as one or more continuous traits found normally throughout the general population. It is a developmental disorder in which certain traits such as impulse control lag in development. Using magnetic resonance imaging of the prefrontal cortex, this developmental lag has been estimated to range from 3 to 5 years. However, the definition of ADHD is based on behaviour and it does not imply a neurological disease. ADHD is classified as a disruptive behavior disorder along with oppositional defiant disorder, conduct disorder and antisocial disorder.
ADHD has three subtypes: ? Predominantly hyperactive-impulsive o Most symptoms (six or more) are in the hyperactivity-impulsivity categories. o Fewer than six symptoms of inattention are present, although inattention may still be present to some degree. ? Predominantly inattentive

o The majority of symptoms (six or more) are in the inattention category and fewer than six symptoms of hyperactivity-impulsivity are present, although hyperactivityimpulsivity may still be present to some degree.
o Children with this subtype are less likely to act out or have difficulties getting along with other children. They may sit quietly, but they are not paying attention to what they are doing. Therefore, the child may be overlooked, and parents and teachers may not notice symptoms of ADHD. ? Combined hyperactive-impulsive and inattentive
o Six or more symptoms of inattention and six or more symptoms of hyperactivityimpulsivity are present.
o Most children with ADHD have the combined type.
Signs and symptoms
Hyperactivity is commonly seen in ADHD Inattention, hyperactivity, and impulsivity are the key behaviors of ADHD. The symptoms of ADHD are especially difficult to define because it is hard to draw the line at where normal levels of inattention, hyperactivity, and impulsivity end and clinically significant levels requiring intervention begin. To be diagnosed with ADHD, symptoms must be observed in two different settings for six months or more and to a degree that is greater than other children of the same age. The symptom categories of ADHD in children yield three potential classifications of ADHD—predominantly inattentive type, predominantly hyperactive-impulsive type, or combined type if criteria for both subtypes are met: Predominantly inattentive type symptoms may include:
? Be easily distracted, miss details, forget things, and frequently switch from one activity to another
? Have difficulty maintaining focus on one task ? Become bored with a task after only a few minutes, unless doing something enjoyable ? Have difficulty focusing attention on organizing and completing a task or learning something new or trouble completing or turning in homework assignments, often losing things (e.g., pencils, toys, assignments) needed to complete tasks or activities ? Not seem to listen when spoken to ? Daydream, become easily confused, and move slowly ? Have difficulty processing information as quickly and accurately as others ? Struggle to follow instructions. Predominantly hyperactive-impulsive type symptoms may include:[29] ? Fidget and squirm in their seats ? Talk nonstop ? Dash around, touching or playing with anything and everything in sight ? Have trouble sitting still during dinner, school, and story time ? Be constantly in motion ? Have difficulty doing quiet tasks or activities. and also these manifestations primarily of impulsivity:[29] ? Be very impatient

? Blurt out inappropriate comments, show their emotions without restraint, and act without regard for consequences
? Have difficulty waiting for things they want or waiting their turns in games Most people exhibit some of these behaviors, but not to the degree where such behaviors significantly interfere with a person's work, relationships, or studies—and in the absence of significant interference or impairment, a diagnosis of ADHD is normally not appropriate. The core impairments are consistent even in different cultural contexts. Symptoms may persist into adulthood for up to half of children diagnosed with ADHD. This rate is difficult to estimate, as there are no official diagnostic criteria for ADHD in adults. ADHD in adults remains a clinical diagnosis. The signs and symptoms may differ from those during childhood and adolescence due to the adaptive processes and avoidance mechanisms learned during the process of socialisation. A 2009 study found that children with ADHD move around a lot because it helps them stay alert enough to complete challenging tasks.
Comorbid disorders
Inattention and "hyperactive" behavior are not the only problems in children with ADHD. ADHD exists alone in only about 1/3 of the children diagnosed with it. Such combinations can greatly complicate diagnosis and treatment. Many co-existing conditions require other courses of treatment and should be diagnosed separately instead of being grouped in the ADHD diagnosis.
Anxiety and depression are some of the disorders that can accompany ADHD. Academic studies, and research in private practice suggest that depression in ADHD appears to be increasingly prevalent in children as they get older, with a higher rate of increase in girls than in boys, and to vary in prevalence with the subtype of ADHD. Where a mood disorder complicates ADHD, it would be prudent to treat the mood disorder first, but parents of children with ADHD often wish to have the ADHD treated first, because the response to treatment is quicker.
Some of the associated conditions are: ? Oppositional defiant disorder (35%) and conduct disorder (26%), both of which
characterized by antisocial behaviors such as stubbornness, aggression, frequent temper tantrums, deceitfulness, lying, or stealing, inevitably linking these comorbid disorders with antisocial personality disorder (ASPD); about half of those with hyperactivity and ODD or CD develop ASPD in adulthood.
? Borderline personality disorder, which was according to a study on 120 female psychiatric patients diagnosed and treated for BPD associated with ADHD in 70 percent of those cases.
? Primary disorder of vigilance, which is characterized by poor attention and concentration, as well as difficulties staying awake. These children tend to fidget, yawn and stretch and appear to be hyperactive in order to remain alert and active.
? Mood disorders. Boys diagnosed with the combined subtype have been shown likely to suffer from a mood disorder.
? Bipolar disorder. As many as 25 percent of children with ADHD have bipolar disorder. Children with this combination may demonstrate more aggression and behavioral problems than those with ADHD alone.

? Anxiety disorder, which has been found to be common in girls diagnosed with the inattentive subtype of ADHD.
? Obsessive-compulsive disorder. OCD is believed to share a genetic component with ADHD and shares many of its characteristics.
Cause
The specific causes of ADHD are not known. There are, however, a number of factors that may contribute to, or exacerbate ADHD. They include genetics, diet and the social and physical environments.
Management
Methods of treatment often involve some combination of behavior modification, life-style changes, counseling, and medication. A 2005 study found that medical management and behavioral treatment is the most effective ADHD management strategy, followed by medication alone, and then behavioral treatment. While medication has been shown to improve behavior when taken over the short term, they have not been shown to alter long-term outcomes.[130] Medications have at least some effect in about 80% of people. Psychosocial
The evidence is strong for the effectiveness of behavioral treatments in ADHD. It is recommended first line in those who have mild symptoms and in preschool aged children. Psychological therapies used include psychoeducational input, behavior therapy, cognitive behavioral therapy (CBT), interpersonal psychotherapy (IPT), family therapy, school-based interventions, social skills training and parent management training. Parent training and education have been found to have short-term benefits. There is a deficiency of good research on the effectiveness of family therapy for ADHD, but the evidence that exists shows that it is comparable in effectiveness to treatment as usual in the community and is superior to medication placebo. It may be worth noting that parents of children with ADHD are more likely to divorce than parents of children without ADHD, particularly when their children are younger than eight years old. Several ADHD specific support groups exist as informational sources and to help families cope with challenges associated with dealing with ADHD. Medication
Methylphenidate (Ritalin) 10 mg tablets Stimulant medication are the medical treatment of choice. There are a number of nonstimulant medications, such as atomoxetine, that may be used as alternatives. There are no good studies of comparative effectiveness between various medications, and there is a lack of evidence on their effects on academic performance and social behaviors. While stimulants and atomoxetine are generally safe, there are side-effects and contraindications to their use. Medications are not recommended for preschool children, as their long-term effects in such young people are unknown. There is very little data on the long-term benefits or adverse effects of stimulants for ADHD. Any drug used for ADHD may have adverse drug reactions such as psychosis and mania, though methylphenidate-induced psychosis is uncommon.[142] People with ADHD have an increased risk of substance abuse, and stimulant medications reduce this risk. Stimulants medications in and of themselves however have the potential for abuse and dependence. Guidelines on when to use medications vary internationally, with the UK's National Institute of Clinical Excellence, for

example, recommending use only in severe cases, while most United States guidelines recommend medications in nearly all cases.
Treatment:
1、EEG biofeedback 2、Sensory integration therapy 3、Occupational therapy 4、Balance biofeedback
