Scrutinising Mental Health Policy + Practice
Not Anti-Psychiatry - Anti-Bad Psychiatry
How is ADHD Diagnosed?
"There are no objective, scientific, diagnostic tests. The diagnosis is based on reports, usually from teachers and parents, that a child 'often' exhibits impulsive/inattentive behaviours, like fidgeting, forgetting and interrupting."
Professor Jon Jureidini, Child Psychiatrist, School of Medicine, University of Adelaide
Despite numerous hyped claims of imminent technological diagnostic breakthroughs, it remains the case that “no biological marker is diagnostic for ADHD”. Nonetheless, many people, including some patients and parents, mistakenly believe ADHD is diagnosed using a series of 'scientific' tests.
In reality the behavioral criteria listed below from DSM-5, produced by the American Psychiatric Association, remain the basis for a diagnosis.

ADHD Diagnostic Criteria.
To meet the DSM5 diagnostic criteria a child should display either:
six of the behavioural criteria below at 1 (Predominantly Inattentive Subtype - sometimes referred to as passive ADHD or ADD)
six of the behavioural criteria below at 2 (Predominantly Hyperactive/Impulsive Subtype)
or six of both 1 and 2 (Combined Subtype)
for at least six months to an extent that is inconsistent with their age and significantly impairs their social and academic functioning. For adolescents 17+ and adults five are sufficient.
often fails to give close attention to details or makes careless mistakes in schoolwork, work, or during other activities
often has difficulty sustaining attention in tasks or play activities
often does not seem to listen when spoken to directly
often does not follow through on instructions and fails to finish schoolwork, chores, or duties in the workplace
often has difficulty organizing tasks and activities
often avoids, dislikes or is reluctant to engage in tasks that require sustained mental effort (such as schoolwork or homework)
often loses things necessary for tasks or activities (e.g., toys, school assignments, pencils, books, or tools)
is often easily distracted by extraneous stimuli
is often forgetful in daily activities
2. Hyperactivity and Impulsivity
often fidgets with hands or feet or squirms in seat
often leaves seat in classroom or in other situations in which remaining seated is expected
often runs about or climbs excessively in situations in which it is inappropriate
often unable to play or engage in leisure activities quietly
is often “on the go” or often acts as if “driven by a motor”
often talks excessively
often blurts out answers before questions have been completed
often has difficulty awaiting turn
often interrupts or intrudes on others (e.g., butts into conversations or games)
DSM5 also recognizes two additional categories of ADHD where children “do not meet the full criteria for ADHD”.
Other Specified ADHD – when clinician “chooses to communicate the specific reason that the presentation does not meet the criteria for ADHD”.
Unspecified ADHD – when the clinician “chooses not to communicate the specific reason that the presentation does not -meet” these criteria.
Editors Comment: Part of the reason I (Dr Martin Whitely) am a critic of ADHD is that I consider it is absurd that normal childhood behaviours like fidgeting, disliking homework, playing loudly, climbing and talking excessively, are regarded as evidence of a childhood psychiatric disorder. What do you think?
Clinicians don't even need to observe ADHD type behaviours. They diagnose children or adolescents with ADHD by relying on third party reports of children exhibiting the above behaviours. Usually parents and teachers are asked to complete a questionnaire detailing if their child always, often, sometimes or never displays these behaviours.
How often is often? How ‘often’ a child or adolescent ‘fidgets’ or ‘interrupts’ or ‘avoids homework’ or ‘fails to remain seated’ or is ‘distracted’ so that they exhibit ‘some impairment’ is not defined in DSM5. Except for those aged 17 and over being required to display less criteria (five instead of six), the diagnostic criteria are identical for pre-schoolers and adults
Bad teachers can cause ADHD type behaviours and then be the first to suggest a child has ADHD (and then provide the evidence used to diagnose it). Many of the diagnostic criteria, in particular "making careless mistakes, not seeming to listen, failing to finish school work, being disorganised, disliking schoolwork or homework, blurting out answers and leaving a seat when remaining seated is expected", are all evidence of a student’s failure to thrive or comply in a school environment. Children is classes controlled by competent, engaging teachers are obviously far less likely to misbehave and are therefore less likely to qualify for a diagnosis. However, a diagnosis of ADHD shifts the focus away from what might be wrong with the teacher or the school and assumes the child's biochemistry is the problem.
As well as being a primary source of the information used by clinicians to diagnose ADHD, research indicates that, in the majority of cases, teachers are the first to suggest a student be referred for diagnosis. There is a high degree of variability in teacher responses to ADHD in regards participation in the diagnostic process, teaching practice and acceptance of the validity of the diagnosis. A child's chances of being diagnosed with ADHD are therefore highly dependent on who there teacher is.
Teacher attitude and practice is just one of many non-biological factors that have been shown to effect rates of ADHD diagnosis and medication use. Variations in both parent and clinician attitudes and practice have a strong impact on a child’s chances of being diagnosed and ‘medicated’ (or 'drugged' depending on your perspective). Arguably a diagnosis of ADHD says more about the adults in a child’s life (parents, teachers and doctors) than it does about the child.
Many other factors including gender (with boys 3x more likely to be diagnosed as girls), ethnicity of students and teachers, divorce, low maternal education, lone parenthood and the receipt of social welfare, sexual abuse, sleep deprivation, perinatal issues, artificial food additives, mobile phone use, postcode and regulatory capture (drug company influence), have all been associated with an increased risk of an ADHD diagnosis. Despite this, and the absence of any supporting evidence, it is widely assumed that a child with ADHD has a neurodevelopmental disorder caused by faulty brain chemistry and function.

 DSM-5 implicitly recognises that boring environments create bored students who misbehave. It states: "Signs of the disorder may be minimal or absent when the person is receiving frequent rewards for appropriate behaviour, is under close supervision, is in a novel setting, is engaged in especially interesting activities, has consistent external stimulation (e.g., via electronic screens) or is in a one-to-one situation (e.g., the clinician’s office)”DSM-5 p. 61
