ADD vs ADHD: what the old name means today
If you or your child were told you "have ADD", you may have wondered whether that still counts. It does. Here is where the name came from, what it is called now, and what inattentive ADHD looks like in children and adults.

In short
- ADD is an old name. It was the official diagnosis from 1980 to 1987, when it was renamed attention deficit hyperactivity disorder (ADHD).
- What people call ADD is now ADHD, predominantly inattentive presentation: trouble with attention, organisation and follow-through without much hyperactivity.
- ADHD has three presentations: inattentive, hyperactive-impulsive and combined. A child needs six symptoms from a list, a person aged 17 or over needs five, with several present before age 12.
- Presentations can change over a lifetime. Hyperactivity tends to fade earlier than inattention, so many adults with ADHD fit the inattentive picture.
- Inattentive ADHD is the most common presentation in the population and the easiest to miss, especially in girls and women. It is assessed and treated like any ADHD.
Is ADD still a diagnosis?
ADD stands for attention deficit disorder. It was the official name for the condition in the 1980s and is no longer used in the diagnostic manuals. Since 1987 the diagnosis has been attention deficit hyperactivity disorder (ADHD), and what people mean by ADD is now called ADHD, predominantly inattentive presentation: ADHD where the main difficulties are with attention, organisation and follow-through rather than hyperactivity and impulsivity.
Healthdirect, the Australian government's health information service, puts it in one line: ADHD used to be called ADD.
So nobody is diagnosed with ADD today, but nobody has lost a diagnosis either. A child described in 1985 as having ADD without hyperactivity, or in 2005 as having ADHD, predominantly inattentive type, has the condition a clinician would now record as inattentive ADHD. The word hyperactivity sits in the name whether or not the person is hyperactive, which is why the old name has hung around: for many people, ADD describes them better.
Where the name ADD came from
The names come from the Diagnostic and Statistical Manual of Mental Disorders (DSM), the American Psychiatric Association's manual, which Australian clinicians use alongside the World Health Organization's ICD. Each edition changed the label.
| Year | Manual | What it called the condition |
|---|---|---|
| 1980 | DSM-III | Attention deficit disorder (ADD), with or without hyperactivity |
| 1987 | DSM-III-R | Attention deficit hyperactivity disorder (ADHD) |
| 1994 | DSM-IV | ADHD with three subtypes: inattentive, hyperactive-impulsive, combined |
| 2013 | DSM-5 | The same three groups, renamed presentations |
| 2022 | DSM-5-TR | No change to the ADHD criteria |
In 1980 DSM-III introduced attention deficit disorder, with or without hyperactivity, so a child could be diagnosed for attention problems alone. In 1987 DSM-III-R brought in the name used today. DSM-IV (1994) described three subtypes, and DSM-5 (2013) renamed them presentations because the subtype a person was given had proved unstable, shifting with setting, with who was reporting and with age.
You will sometimes read that DSM-5 removed ADD in 2013. ADHD became the name in 1987; what changed in 2013 was that subtypes became presentations.
The three presentations of ADHD today
ADHD has two symptom lists, nine for inattention and nine for hyperactivity-impulsivity. The presentation depends on which list a person reaches the threshold on.
- Predominantly inattentive presentation. Enough inattention symptoms, not enough hyperactive-impulsive ones. This is what most people mean by ADD.
- Predominantly hyperactive-impulsive presentation. The reverse.
- Combined presentation. Both thresholds met.
The threshold is six symptoms from a list for children and five for people aged 17 and over. The other rules are the same for every presentation: symptoms have lasted at least six months, several were present before age 12, they show up in two or more settings such as home and school or work, they clearly interfere with daily life, and nothing else explains them better.
Presentations change over a lifetime
The presentation describes how ADHD looks now, not a fixed type. The US National Resource Center on ADHD notes that a person can change presentations during their lifetime. A review of 546 studies by Willcutt and colleagues, done to inform DSM-5, found marked instability in all three DSM-IV subtypes over time, which is why DSM-5 stopped treating them as distinct forms of the disorder. Hyperactivity tends to fade first: in a study that followed 128 boys with ADHD over four years, hyperactive and impulsive symptoms declined earlier and faster than inattention. Australia's ADHD guideline notes that inattention often becomes more evident as children move through school, and that adults are more likely to keep inattentive symptoms than obvious hyperactivity.
In the general population the inattentive presentation is the most common of the three; children with the combined presentation are more likely to be referred to clinics, so clinic waiting rooms give a different impression.
The nine inattention symptoms in plain words
These are the nine inattention symptoms in the current criteria, in everyday language. Each has to happen often, be out of step with the person's age, and show up across settings. Everyone does some of these sometimes; the question is how many, how often, and at what cost.
| Symptom | In a child | In an adult |
|---|---|---|
| Misses details, makes careless mistakes | Rushed schoolwork full of avoidable errors | Typos in emails, skipped steps on forms |
| Trouble keeping attention on a task | Drifts off during lessons, stories or games | Loses the thread in meetings, rereads the same page |
| Seems not to listen when spoken to | Has to be asked twice, looks switched off | Nods along without taking it in; others feel ignored |
| Does not follow through | Starts homework or chores and does not finish | Projects started and abandoned, half-done jobs at home |
| Trouble organising tasks and time | Messy desk, lost worksheets, no idea what is due when | Missed deadlines, poor sense of time |
| Avoids tasks that need sustained mental effort | Puts off homework, especially anything long or dull | Puts off tax, paperwork and long reports until urgent |
| Loses things needed for tasks | School hats, jumpers, pencil cases, library books | Keys, phone, wallet, glasses, again and again |
| Easily distracted | Pulled off task by noise, movement or their own thoughts | Open tabs, notifications, one thought leading to another |
| Forgetful in daily life | Forgets to hand in notes, bring equipment, do chores | Forgets appointments, bills and return calls |
A child needs six of these for the inattentive presentation; a 17-year-old or adult needs five. Not every dreamy child or forgetful adult has ADHD, and the Australian guideline asks assessors to check for other conditions and medicines that can look like it. Sorting this out is what an assessment is for.
Why inattentive ADHD gets missed, especially in girls and women
Hyperactivity gets noticed because it disrupts other people. Inattention mostly costs the person themselves. Australia's ADHD guideline tells clinicians that many children and adults never show the visible symptoms of hyperactivity and impulsivity, that inattentive symptoms may not be identified until secondary school or later, when organisation and independent study are expected, and that people may have built compensation strategies that mask them.
The same guideline warns that ADHD could be under-recognised in girls and women, who are less likely to be referred for assessment, and may be more likely to have undiagnosed ADHD or to be given an incorrect diagnosis such as an anxiety or depressive disorder. Healthdirect says ADHD is more commonly diagnosed in young males but is underdiagnosed in young females and in adults.
Research backs this up. In a US clinic study of 140 girls and 140 boys with ADHD, girls were more likely to have the predominantly inattentive type and less likely to show problems at school; the authors warned this could bias referrals against girls. A 2014 review concluded that inattentiveness is more common than hyperactivity in girls with ADHD, that teachers are less likely to notice inattention because it is less disruptive, that girls with anxiety or depressive symptoms may be treated for those without ADHD being considered, and that women tend to be older than men when diagnosed.
Raising Children Network makes the point for parents: inattentive characteristics can be subtle, so it may just seem that a child daydreams. See ADHD in women and girls and, for late diagnosis generally, ADHD in adults.
How inattentive ADHD is assessed and treated in Australia
Assessment
The presentation does not change who can diagnose or how. In Australia, ADHD is diagnosed by paediatricians, psychiatrists and psychologists, usually on referral from a GP. The national guideline, published by the Australasian ADHD Professionals Association in 2022, says an assessment should include a full clinical and psychosocial assessment, a developmental, mental health and medical history, and reports from observers such as a teacher, with symptoms confirmed in more than one setting. Rating scales help but a diagnosis should not rest on them alone. For an adult, that means tracing attention problems back to childhood, which is where old school reports and family memories come in.
A psychologist can diagnose ADHD but cannot prescribe, and who can prescribe depends on your state or territory; our ADHD assessment page sets out the rules. The free ADHD test is a short screener; it cannot diagnose, and an assessment can conclude ADHD, not ADHD, or something else.
Treatment
The guideline makes no separate recommendations by presentation. It recommends medication, which it says is most effective at reducing core ADHD symptoms, alongside supports that help with day-to-day impact, such as parent and family training for children and cognitive behavioural therapy for adults.
Where symptoms cause significant impairment, the guideline recommends a stimulant (methylphenidate, dexamfetamine or lisdexamfetamine) first, for children aged 5 to 17 and for adults, and a non-stimulant (atomoxetine or guanfacine, with clonidine also an option for children) if stimulants are unsuitable, not tolerated or do not work. The evidence does not support treating the inattentive presentation differently: the 546-study review found minimal support for a difference between inattentive and combined types in treatment response, and a small double-blind crossover trial of 25 children (10 inattentive, 15 combined) found both groups improved on methylphenidate with no difference in response. Medication suits some people and not others, and the decision sits with the prescribing doctor. Our ADHD medication guide covers the options, side effects and Schedule 8 rules.
What to do if an old report says ADD
An old report is not wrong, just dated. Depending on when it was written, ADD may have been the full diagnostic name (1980 to 1987), shorthand for the DSM-IV subtype (1994 to 2013), or a clinician's informal way of saying ADHD without much hyperactivity. In each case it describes what is now called ADHD, predominantly inattentive presentation.
- Keep the report. For an adult assessment, the hardest thing to establish is that symptoms were present before age 12. A childhood report, whatever it calls the condition, is evidence of that.
- Check what the paperwork is for. Schools, universities, employers and prescribers each decide what documentation they accept. Some take an old report; others want something current. Ask before paying for a new assessment.
- Expect the current criteria to be applied. Anyone assessed today is measured against the current criteria: five symptoms from age 17, several present before 12, in two or more settings, with impairment. A childhood diagnosis does not guarantee the adult threshold is still met, and the presentation may have changed.
- Say ADD if that is the language you have. Clinicians know what it means; a new report would call it ADHD, predominantly inattentive presentation.
Questions people ask
Is ADD still a diagnosis?
Not under that name. Since 1987 the diagnosis has been attention deficit hyperactivity disorder (ADHD), and what used to be called ADD is now ADHD, predominantly inattentive presentation. The condition has not gone anywhere; only the label changed.
What is the difference between ADD and ADHD?
Today there is no difference in substance. ADD was the official name from 1980 to 1987 and survives as shorthand for ADHD without much hyperactivity. ADHD is the umbrella diagnosis with three presentations: inattentive, hyperactive-impulsive and combined. What people call ADD is the inattentive presentation.
What are the symptoms of ADD in adults?
Trouble holding attention, missing details, not following through, poor organisation and time management, putting off anything that needs sustained effort, losing things, distractibility and forgetting daily tasks. An adult needs at least five of the nine inattention symptoms, with several present before age 12 and affecting more than one part of life. Hyperactivity may be slight or absent.
Can you have ADD without hyperactivity?
Yes. That is the predominantly inattentive presentation of ADHD, the most common presentation in population studies. The word hyperactivity is in the name, but a person does not need hyperactive or impulsive symptoms to meet the criteria. Hyperactivity also tends to fade with age while inattention persists, so many adults with ADHD fit this picture.
Is inattentive ADHD less serious?
No. A review of 546 studies found that people who meet ADHD criteria have significant and persistent difficulties in social, academic, work and everyday functioning, and that differences between presentations mostly reflect how many of each symptom a person has. Inattentive symptoms also persist longer than hyperactive ones. The particular risk is going unrecognised for years.
Does inattentive ADHD need medication?
Not automatically. Australia's ADHD guideline recommends medication where symptoms cause significant impairment, as part of a plan that also includes supports such as parent training or cognitive behavioural therapy. It makes no separate recommendation by presentation, and research shows the inattentive and combined presentations respond to stimulants in the same way. The decision is made with the prescribing doctor.
