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 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 founded and edited The ADHD Report, a peer-reviewed journal 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]
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]
