Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterised by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and otherwise age-inappropriate.
Methylphenidate, sold under the brand names Ritalin and Concerta among others, is a potent central nervous system (CNS) stimulant used medically to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, narcolepsy. It is a primary medication for ADHD ; it may be taken by mouth or applied to the skin, and different formulations have varying durations of effect. For ADHD, the effectiveness of methylphenidate is comparable to atomoxetine but modestly lower than amphetamines, alleviating the executive functioning deficits of sustained attention, inhibition, working memory, reaction time and emotional self-regulation.
Developmental disorders comprise a group of psychiatric conditions originating in childhood that involve serious impairment in different areas. There are several ways of using this term. The most narrow concept is used in the category "Specific Disorders of Psychological Development" in the ICD-10. These disorders comprise developmental language disorder, learning disorders, developmental coordination disorders, and autism spectrum disorders (ASD). In broader definitions, attention deficit hyperactivity disorder (ADHD) is included, and the term used is neurodevelopmental disorders. Yet others include antisocial behavior and schizophrenia that begins in childhood and continues through life. However, these two latter conditions are not as stable as the other developmental disorders, and there is not the same evidence of a shared genetic liability.
Dexmethylphenidate, sold under the brand name Focalin among others, is a potent central nervous system (CNS) stimulant used to treat attention deficit hyperactivity disorder (ADHD) in those over the age of five years. It is taken by mouth. The immediate release formulation lasts up to five hours while the extended release formulation lasts up to twelve hours. It is the more active enantiomer of methylphenidate.
Adult Attention Deficit Hyperactivity Disorder is the persistence of attention deficit hyperactivity disorder (ADHD) into adulthood. It is a neurodevelopmental disorder, meaning impairing symptoms must have been present in childhood, except for when ADHD occurs after traumatic brain injury. Specifically, multiple symptoms must be present before the age of 12, according to DSM-5 diagnostic criteria. The cutoff age of 12 is a change from the previous requirement of symptom onset, which was before the age of 7 in the DSM-IV. This was done to add flexibility in the diagnosis of adults. ADHD was previously thought to be a childhood disorder that improved with age, but recent research has disproved this. Approximately two-thirds of childhood cases of ADHD continue into adulthood, with varying degrees of symptom severity that change over time and continue to affect individuals with symptoms ranging from minor inconveniences to impairments in daily functioning.
Cognitive disengagement syndrome (CDS) is an attention syndrome characterised by prominent dreaminess, mental fogginess, hypoactivity, sluggishness, slow reaction time, staring frequently, inconsistent alertness, and a slow working speed. To scientists in the field, it has reached the threshold of evidence and recognition as a distinct syndrome.
Russell Alan BarkleyFAPA is a retired American clinical neuropsychologist who was a clinical professor of psychiatry at the VCU Medical Center until 2022 and president of Division 12 of the American Psychological Association (APA) and of the International Society for Research in Child and Adolescent Psychopathology (ISRCAP). Involved in research since 1973 and a licensed psychologist since 1977, he is an expert on attention-deficit hyperactivity disorder (ADHD) and has devoted much of his scientific career to studying ADHD and related fields like childhood defiance. He proposed the renaming of sluggish cognitive tempo (SCT) to cognitive disengagement syndrome (CDS).
Guanfacine, sold under the brand name Tenex (immediate-release) and Intuniv (extended-release) among others, is an oral alpha-2a agonist medication used to treat attention deficit hyperactivity disorder (ADHD) and high blood pressure. Guanfacine is FDA-approved for monotherapy treatment of ADHD, as well as being used for augmentation of other treatments, such as stimulants. Guanfacine is also used off-label to treat tic disorders, anxiety disorders, and post-traumatic stress disorder (PTSD).
Attention deficit hyperactivity disorder predominantly inattentive, is one of the three presentations of attention deficit hyperactivity disorder (ADHD). In 1987–1994, there were no subtypes or presentations and thus it was not distinguished from hyperactive ADHD in the Diagnostic and Statistical Manual (DSM-III-R). In DSM-5, subtypes were discarded and reclassified as presentations of the same disorder that change over time.
Jack Gantos is an American author of children's books. He is best known for the fictional characters Rotten Ralph and Joey Pigza. Rotten Ralph is a cat who stars in twenty picture books written by Gantos and illustrated by Nicole Rubel from 1976 to 2014. Joey Pigza is a boy with attention-deficit hyperactivity disorder (ADHD), featured in five novels from 1998 to 2014.
Despite the scientifically well-established nature of attention deficit hyperactivity disorder (ADHD), its diagnosis, and its treatment, each of these has been controversial since the 1970s. The controversies involve clinicians, teachers, policymakers, parents, and the media. Positions range from the view that ADHD is within the normal range of behavior to the hypothesis that ADHD is a genetic condition. Other areas of controversy include the use of stimulant medications in children, the method of diagnosis, and the possibility of overdiagnosis. In 2009, the National Institute for Health and Care Excellence, while acknowledging the controversy, stated that the current treatments and methods of diagnosis are based on the dominant view of the academic literature.
Joey Pigza Swallowed the Key is a children's novel by Jack Gantos, published in 1998. It is the first of a series of books featuring the character Joey Pigza. The book was a National Book Award finalist.
Edward McKey Hallowell is an American psychiatrist, speaker, New York Times best-selling author and podcast host. He specializes in ADHD and is the founder of the Hallowell ADHD Centers. Hallowell is the author of 20 books, including the Distraction series, co-authored with Dr. John Ratey.
Attention deficit hyperactivity disorder management options are evidence-based practices with established treatment efficacy for ADHD. Approaches that have been evaluated in the management of ADHD symptoms include FDA-approved pharmacologic treatment and other pharmaceutical agents, psychological or behavioral approaches, combined pharmacological and behavioral approaches, cognitive training, neurofeedback, neurostimulation, physical exercise, nutrition and supplements, integrative medicine, parent support, and school interventions. Based on two 2024 systematic reviews of the literature, FDA-approved medications and to a lesser extent psychosocial interventions have been shown to improve core ADHD symptoms compared to control groups.
Central nervous system diseases or central nervous system disorders are a group of neurological disorders that affect the structure or function of the brain or spinal cord, which collectively form the central nervous system (CNS). These disorders may be caused by such things as infection, injury, blood clots, age related degeneration, cancer, autoimmune disfunction, and birth defects. The symptoms vary widely, as do the treatments.
Joseph Biederman was an American academic psychiatrist. He was Chief of the Clinical and Research Programs in Pediatric Psychopharmacology and Adult ADHD at the Massachusetts General Hospital and a professor of psychiatry at Harvard Medical School.
Mental disorders diagnosed in childhood can be neurodevelopmental, emotional, or behavioral disorders. These disorders negatively impact the mental and social wellbeing of a child, and children with these disorders require support from their families and schools. Childhood mental disorders often persist into adulthood. These disorders are usually first diagnosed in infancy, childhood, or adolescence, as laid out in the DSM-5 and in the ICD-11.
Hyperactivity has long been part of the human condition, although hyperactive behaviour has not always been seen as problematic.
The Swanson, Nolan and Pelham Teacher and Parent Rating Scale (SNAP), developed by James Swanson, Edith Nolan and William Pelham, is a 90-question self-report inventory designed to measure attention deficit hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms in children and young adults.
I Am Not Joey Pigza is a 2007 children's novel by Jack Gantos. It is the fourth book of a series featuring the character Joey Pigza, a boy with attention deficit hyperactivity disorder.
