Russell Alan Barkley FAPA (born December 27, 1949) 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. [3] [4] [5] 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. [6] He proposed the renaming of sluggish cognitive tempo (SCT) to cognitive disengagement syndrome (CDS). [7]
Besides his clinical work, he is also an expert in the neuropsychology of executive function and self-regulation. He is board certified in three clinical specialties: clinical neuropsychology, clinical psychology, and clinical child and adolescent psychology. [4] [8]
Russell Alan Barkley was born in Newburgh, New York. He was one of five children, born to US Air Force Colonel Donald Stuart Barkley (27 February 1916 – 15 June 1999) and Mildred Minerva née Terbush (10 September 1914 – 25 April 2008). Barkley served in the United States Air Force from 1968 to 1972, including a tour of duty in Vietnam. [9] He had a fraternal twin brother, Ronald Foster Barkley, [10] [11] who was killed in a car crash on 24 July 2006. Barkley attributes his brother's history of dangerous and reckless behavior, including not wearing a seat belt and speeding at the time of his crash, to untreated ADHD. [12] Ronald was several times over the legal alcohol limit, speeding and not wearing a seat belt at the time of his fatal crash. [13]
Barkley earned an Associate of Arts from Wayne Community College in Goldsboro, North Carolina in June 1972, and a BA in psychology from the University of North Carolina at Chapel Hill. [14] He earned an MA and Ph.D. in clinical psychology from Bowling Green State University in Bowling Green, Ohio. [15] From July 1976 to 1977, Barkley was an intern at the University of Oregon Health Sciences Center in Portland, Oregon. [14] [16]
In 1977, Barkley began his professional career at the Medical College of Wisconsin and Milwaukee Children's Hospital, where in 1978, he founded the Neuropsychology Service and served as its chief until 1985. He then moved to the University of Massachusetts Medical School, where he served as Director of Psychology from 1985 to 2000. Barkley was professor of psychiatry and neurology at the University of Massachusetts Medical Center. [17] [18] [19] In 2005, he joined the State University of New York Upstate Medical University (SUNY) in Syracuse, New York, where he was a consultant and research professor of psychiatry. [20] [21] He taught at the Medical University of South Carolina from 2003 to 2016 and then moved to Virginia Commonwealth University Medical Center in Richmond, Virginia, where he taught in the Department of Psychiatry until 2020. [4] [5] [22] [ non-primary source needed ]
Until 2022, he served as president of the Section on Clinical Child Psychology (Division 12) of the American Psychological Association (APA) and of the International Society for Research in Child and Adolescent Psychopathology. [3] [4] [5] He is a fellow of the APA. [3] [23]
Barkley led the first International Consensus Statement on ADHD. [24] He is known for his research contributions [25] [26] [27] [28] [29] including multiple papers from his longitudinal study in Milwaukee, Wisconsin; [30] [31] the persistence of ADHD into adulthood; [32] [33] [34] his development of a theory of ADHD as a disorder of executive functioning and self-regulation; [35] [36] establishing the nature of emotional dysregulation in ADHD; [25] [37] early research on family interaction patterns in ADHD children; [38] his more recent studies on the nature of ADHD in adults; [39] initially researching the effects of stimulant medication; [40] [41] [42] early intervention for children at risk for ADHD; [43] training parents to manage ADHD and defiant behavior; [44] the pervasiveness of impairments and long-term risks associated with ADHD; [45] [46] and the nature of cognitive disengagement syndrome. [47]
He has given more than 800 invited lectures in more than 30 countries during his career, as part of his effort to disseminate science. [8] [48] [28] Barkley edited ''The ADHD Report'', a newsletter for clinicians and parents, until its 30th and final volume in 2022. [49] He has performed his forever last invited public lecture at the Centro Archimede Medical Centre, where he discussed ADHD, CDS and related topics, in Italy, September 30, 2023. [50] [51]
Besides his books, he has published six clinical rating scales related to ADHD, executive functioning, and impairment [4] [5] and clinical manuals for diagnosis and treatment. [52] [53] One of Barkley's rating scales for adult ADHD evaluates CDS, [54] a distinct syndrome from ADHD. [55]
In 1978, Barkley wrote that "Stimulant drug studies based primarily on measures of teacher opinion have frequently concluded that these drugs improve the achievement of hyperkinetic children. However, a review of those studies using more objective measures of academic performance revealed few positive short-term or long-term drug effects on these measures. What few improvements have been noted can be readily attributed to better attention during testing. The major effect of the stimulants appears to be an improvement in classroom manageability rather than academic performance". [56] In 1991, Barkley noted that "Psychostimulant medications (e.g., Ritalin) are highly effective treatments for the symptomatic management of children with ADHD as they can enhance significantly their attention span, impulse control, academic performance, and peer relationships". [56]
In response to critics who point to countries with lower rates of diagnoses and medication of children for ADHD, Barkley said, "So what? We do not let the rest of the world set our standards of care when we do more research on childhood disorders--specifically ADHD--than other countries combined?". [57]
Barkley believes that medications such as methylphenidate and dextroamphetamine should be downgraded to schedule III. [58]
During an interview in 2001, Barkley said that "All of the research we have indicates that these drugs are some of the safest that we employ in the field of psychiatry and psychology. That's not to say that we know everything about them. But we know a lot more than we know about cough medicines and Tylenol and aspirins and other things that children swill whenever they come down with a common cold. Nobody asks those questions about those over-the-counter medications, yet we know substantially less about them". [59]
Barkley has compared the symptomatic impairments of ADHD to a physical handicap, with accommodations and treatment being the equivalent of a wheelchair. [60] On 16 November 1998 he said that "[methylphenidate] will be ranked as one of the leading developments in this century for helping individuals". [61]

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by executive dysfunction occasioning symptoms of inattention, hyperactivity, impulsivity and emotional dysregulation that are excessive and pervasive, impairing in multiple contexts, and developmentally-inappropriate.
Methylphenidate, sold under the brand names Ritalin and Concerta among others, is a central nervous system (CNS) stimulant used medically to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, narcolepsy. It is a first-line treatment 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.
Atomoxetine, sold under the brand name Strattera, is a selective norepinephrine reuptake inhibitor medication used to treat attention deficit hyperactivity disorder (ADHD) and, to a lesser extent, cognitive disengagement syndrome. It may be used alone or along with psychostimulants. It enhances the executive functions of self-motivation, sustained attention, inhibition, working memory, reaction time and emotional self-regulation. Use of atomoxetine is only recommended for those who are at least six years old. It is taken orally. The effectiveness of atomoxetine is comparable to the commonly prescribed stimulant medication methylphenidate.
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.
Hyperfocus is an intense form of mental concentration or visualization that focuses consciousness on a subject, topic, or task. In some individuals, various subjects or topics may also include daydreams, concepts, fiction, the imagination, and other objects of the mind. Hyperfocus on a certain subject can cause side-tracking away from assigned or important tasks.
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.
Child psychopathology refers to the scientific study of mental disorders in children and adolescents. Oppositional defiant disorder, attention-deficit hyperactivity disorder, and autism spectrum disorder are examples of psychopathology that are typically first diagnosed during childhood. Mental health providers who work with children and adolescents are informed by research in developmental psychology, clinical child psychology, and family systems. Lists of child and adult mental disorders can be found in the International Statistical Classification of Diseases and Related Health Problems, 10th Edition (ICD-10), published by the World Health Organization (WHO) and in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), published by the American Psychiatric Association (APA). In addition, the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood is used in assessing mental health and developmental disorders in children up to age five.
Cognitive disengagement syndrome (CDS) is a syndrome characterized by developmentally-inappropriate, impairing and persistent levels of decoupled attentional processing from the ongoing external context and resultant hypoactivity. Symptoms often manifest in difficulties with staring, mind blanking, withdrawal, mental confusion and maladaptive mind wandering alongside delayed, sedentary or slow motor movements. To scientists in the field, it has reached the threshold of evidence and recognition as a distinct syndrome.
Neurodevelopmental disorders are a group of mental conditions affecting the development of the nervous system, which includes the brain and spinal cord. According to the American Psychiatric Association Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, (DSM-5) published in 2013, these conditions generally appear in early childhood, usually before children start school, and can persist into adulthood. The key characteristic of all these disorders is that they negatively impact a person's functioning in one or more domains of life depending on the disorder and deficits it has caused. All of these disorders and their levels of impairment exist on a spectrum, and affected individuals can experience varying degrees of symptoms and deficits, despite having the same diagnosis.
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.
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.
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.
In psychology and neuroscience, executive dysfunction, or executive function deficit is a disruption to the efficacy of the executive functions, which is a group of cognitive processes that regulate, control, and manage other cognitive processes. Executive dysfunction can refer to both neurocognitive deficits and behavioural symptoms. It is implicated in numerous psychopathologies and mental disorders, as well as short-term and long-term changes in non-clinical executive control. Executive dysfunction is the mechanism underlying ADHD paralysis, and in a broader context, it can encompass other cognitive difficulties like planning, organizing, initiating tasks and regulating emotions. It is a core characteristic of ADHD and can elucidate numerous other recognized symptoms.
Hyperactivity has long been part of the human condition, although hyperactive behaviour has not always been seen as problematic.

Virginia I. Douglas was a Canadian psychologist. She was a professor at McGill University in Montreal, Canada, noted for her contributions to the study of attention deficit hyperactivity disorder (ADHD).
The ADHD Rating Scale (ADHD-RS) is a parent-report or teacher-report inventory created by George J. DuPaul, Thomas J. Power, Arthur D. Anastopoulos, and Robert Reid consisting of 18–90 questions regarding a child's behavior over the past 6 months. The ADHD Rating Scale is used to aid in the diagnosis of attention deficit hyperactivity disorder (ADHD) in children ranging from ages 5–17.
