People with ADHD are not intelligent. This is nearly totally incorrect. In fact, lower IQ isn't directly associated to ADHD. Because they function differently from the rest of the population, people with ADHD are frequently seen as having poor intelligence. This opinion is completely wrong and unfair.
The majority of people with ADHD have average or above-average intelligence. Some studies show that up to 90% of people with ADHD have IQ scores in the normal to high range. Others report that as many as two-thirds of people with ADHD have IQ scores in the superior range. Regardless of the number, this means that about 10% of people with ADHD have intelligence levels below average.
It is very common for people with ADHD to receive low IQ scores because they fail the most basic requirement for taking an IQ test: paying attention. People who don't pay attention at home, in school, or at work can't be expected to perform well on tests that require focused attention. For this reason, it's safe to say that everyone with ADHD is inherently lacking in intelligence. However, the majority of people with ADHD have IQ scores that are in the normal to high range.
Many people, however, find solace in the idea that children with ADHD are smarter than those who do not have the disease. Intelligence and ADHD, on the other hand, do not go hand in hand. Some ADHD patients may have higher IQs. However, many others may appear to have lower IQ scores because they are more able to compensate for their disorder's symptoms by using their brains differently.
It is true that adults with ADHD tend to score higher on measures of intelligence than adults without the condition. However, this does not mean that children with ADHD are smart or that it is possible to tell how smart someone with the disorder is based on their age. The same can be said of adults with ADHD. Their higher-than-average scores on intelligence tests may simply reflect that they have better attention spans and are more likely to work hard at tasks that require effort rather than giving up easily.
Some studies have shown that adolescents and young adults with ADHD may show signs of high intelligence, but these results are controversial. There is no evidence to suggest that children or adults with ADHD are immune to learning disabilities. Indeed, many receive special education services due to poor academic performance.
Intelligence is defined as "the ability to learn" and those who have it are called intelligent persons. It is estimated that about 5% of children have ADHD.
For example, of the 18 research examined that did not clearly mention an IQ cut-off point, the mean range of IQ reported in the studies among adults with ADHD ranged from 102 to 110. Given that lower IQ is connected with ADHD, it stands to reason that people with ADHD may be misrepresented.... The overall median estimate was 105, with a range of 92 to 115.

It is important to note that there is no single "correct" way to measure intelligence. Different tests are used to assess different aspects of intelligence. The Wechsler scales are commonly used measures of general intellectual ability. They require only 15 minutes to complete and can be used with individuals from three years of age up through the elderly. The WISC-IV is designed to provide clinicians and researchers with multiple indicators of cognitive ability. It includes four primary indexes: FSIQ, VIQ, PIQ, and Processing Speed Index (PSI).
The WISC-IV Processing Speed Index is based on information gathered during the completion of four subtests that measure visual perception, visual-motor skills, auditory perception, and the speed at which one can process information obtained through these senses.
These data imply that ADHD is identical in children with high, normal, and low IQ, however high IQ may moderate some outcomes, such as reading achievement. ADHD diagnosis and treatment are critical for all children, regardless of cognitive ability.
Others who are unfamiliar with an ADHD diagnosis and the symptoms linked with the disorder may easily misinterpret it with carelessness or a lack of intelligence. However, those who know about ADHD understand that this is not true for anyone with the condition. People with ADHD can be very focused and intense-focus people who complete tasks without losing track of time.
Those who don't know anything about ADHD might think someone with this condition isn't quite right in the head. However, those with ADHD know better. In fact, those with ADHD experience the world through visual cues instead of listening to music while walking down the street or sitting in class. They also find it difficult to pay attention to more than one thing at a time. Finally, those who know nothing about ADHD might assume that someone who loses focus during class or work must be drunk or high. This is not the case for people with ADHD; they just need more time to get their thoughts together after being distracted.
People with ADHD know that they have a problem paying attention and tend to forget details. As a result, they often go over things in their minds repeatedly until they're sure of themselves. This may cause them to say or do things without thinking first. For example, they may offer an opinion on something before really knowing all the facts.
