Forty Gifted Children in a Disability Queue

What the research found

A team at Sapienza University in Rome pulled the clinical records of 456 school-aged children who had been referred to their child neuropsychiatry unit over two years for suspected specific learning disorders (SLD) or attention-deficit/hyperactivity disorder (ADHD). None of these children arrived with a question about giftedness. They arrived because a parent or teacher thought something was wrong.

The researchers then applied a cognitive filter. They kept only the children whose General Ability Index (GAI) was above 120. The GAI is a score derived from the verbal and reasoning parts of the Wechsler intelligence test; unlike the more familiar Full-Scale IQ, it deliberately leaves out working memory and processing speed. That matters, because those two areas are often where bright children with a learning difficulty or attention problem score lower, which can drag a Full-Scale IQ down and hide the underlying ability. Using the GAI instead lifted the proportion of children who counted as gifted in this clinic from about 5 percent to 8.8 percent. Forty children met the threshold.

The forty were not evenly split. Ninety percent were boys. Their mean age was 9.3 years, and their mean GAI was 130.2. When the full assessments were complete, only 4 of the 40 (10 percent) had giftedness and no other diagnosis. The rest carried at least one recognised condition: 15 (37.5 percent) had a neurodevelopmental disorder such as SLD or ADHD, 8 (20 percent) had a psychopathological condition such as anxiety or depression, and 13 (32.5 percent) had both. On the authors’ reckoning in the discussion, roughly 85 percent of the sample qualified as twice-exceptional, meaning gifted and disabled at once.

The most striking numbers concern the gap between what was suspected and what was found. ADHD was the leading worry at referral, named in 55 percent of cases, yet it was confirmed in only 22.5 percent. Learning disorders ran the other way: fewer children were referred for a suspected SLD than were eventually diagnosed with one, which the authors read as evidence that able children can mask academic difficulty with sheer cleverness until it finally surfaces. Attention concerns, by contrast, were frequently better explained by boredom, over-excitability or the mismatch between a quick mind and an unchallenging classroom.

One finding held across every group, including the four children with no diagnosis at all. On average, working memory (mean 106.7) and processing speed (mean 97.7) sat well below the reasoning-based GAI of 130.2. In more than half the sample the four index scores were so uneven that the overall Full-Scale IQ could not be read as a single number. The authors take this as a sign that the dip in working memory and processing speed is, to some degree, a feature of giftedness itself, not proof of a separate disorder.

What it means for you and your child

The honest headline is a modest one. This is a retrospective look at forty children in a single Italian clinic, all of whom were already in the system because someone suspected a problem. That is a heavily filtered group. It tells you nothing about how common giftedness or twice-exceptionality is in the general population, and it cannot establish that one thing causes another. The authors themselves flag the clinical setting, the exclusion of autism, and the absence of any long-term follow-up as real limits. Treat the figures as a careful description of who walked through one door, not as a law about all bright children.

Within those limits, two practical points are worth holding onto. The first is that a referral for a difficulty is not the opposite of a referral for a gift. In this sample the two travelled together far more often than not. If your child is clearly able yet struggling in a way that has prompted talk of assessment, the more useful question is rarely “gifted or disabled?” It is usually “both, and in what proportion?” A thorough evaluation should be able to hold that complexity rather than force a single label.

The second point is a caution about attention in particular. Here, the majority of children referred for suspected ADHD did not meet the criteria on close examination. Restlessness, impatience and inattention in a very able child can genuinely reflect ADHD, and where they do, the study is clear that the condition deserves proper treatment. But those same behaviours can also come from a child who has finished the work three times over and has nowhere to put the energy. Distinguishing the two takes a careful clinician, not a checklist, and it is worth pressing for that care before a diagnosis is settled.

There is a quieter message in the four children who left with no diagnosis at all. Giftedness on its own can make school and friendships hard. A bright child who is out of step with the pace around them may look, to a worried adult, like a child with a disorder. That is not a reason to dismiss real difficulty. It is a reason to ask what a child actually needs, which is often a more stretching curriculum and better-matched teaching, rather than to assume the difficulty must have a clinical name. If your child is gifted and unhappy, both possibilities deserve a hearing.
