This is a great question, and the short answer is “yes.” ADHD symptoms are something that exist on a spectrum or a continuum. But the longer answer is a little bit more complicated. There are two important factors to consider — the type of symptoms a child has and how intense they are.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
ADHD Spectrum: Not all Children Are the Same
ADHD is not a breakdown of the brain in one spot. It's a breakdown in the connectivity, the communication networks, and an immaturity in these networks. These brain networks are interrelated around emotion, attention, behavior, and arousal.
Asperger's and ADHD are both considered neurodevelopmental disorders, but ADHD does not fall under the autism spectrum. ADHD is far more common than Asperger's Syndrome, and according to the National Alliance on Mental Illness (NAMI), ADHD affects nine percent of children ages three through 17.
Some of the conditions that are most common among those who describe themselves as neurodivergent include: Autism spectrum disorder (this includes what was once known as Asperger's syndrome). Attention-deficit hyperactivity disorder (ADHD). Down syndrome.
In short, the answer is “no”. While autism and ADHD are both neurological conditions, they're not the same thing. There are, however, many overlapping symptoms between ADHD and autism and it's not uncommon for people to have a dual diagnosis.
But in fact, autism and ADHD often coincide. An estimated 30 to 80 percent of children with autism also meet the criteria for ADHD and, conversely, 20 to 50 percent of children with ADHD for autism.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children.
ADHD: a disabling condition
It is recognized as a disability under the 1992 Disability Discrimination Act.
Attention deficit hyperactivity disorder (ADHD) is a mental disability condition that is characterized by excessive impulsivity and hyperactivity. Those with ADHD may also have problems focusing on particular tasks or exhibit high inattention levels as well.
ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Although 2019 research suggests some symptoms of ADHD and ASD overlap, there are distinct differences. A person with ADHD may have attention, hyperactivity, and impulsivity challenges. But an autistic individual may have difficulties with communication, social interaction, and restricted or repetitive behaviors.
In total, 12.1% of children had obtained an ADHD diagnosis before being subsequently diagnosed with autism.
Attention deficit-hyperactivity disorder (ADHD) is a neurobehavioral disorder that affects 3-5 percent of all American children. It interferes with a person's ability to stay on a task and to exercise age-appropriate inhibition (cognitive alone or both cognitive and behavioral).
Regardless of how well he or she performs in school, a student who has trouble concentrating, reading, thinking, organizing or prioritizing projects, among other important tasks, because of ADHD may have a disability and be protected under Section 504.
Reasons for Misdiagnosis
Many symptoms of autism and ADHD overlap, such as difficulty concentrating, poor social skills, frequent pacing, and repetitive behaviors. Many children with these symptoms receive an ADHD diagnosis before their doctor eventually concludes that the true cause is autism.
Attention deficit hyperactivity disorder (ADHD) is a condition that affects people's behaviour. People with ADHD can seem restless, may have trouble concentrating and may act on impulse.
Clinical studies found that medication for attention-deficit/hyperactivity disorder (ADHD) is effective in coexisting autism spectrum disorder (ASD), but current research is based on small clinical studies mainly performed on children or adolescents.
Others will continue to experience ADHD symptoms through their adolescent years into adulthood. ADHD is not on the autism spectrum. However, both ADHD and autism spectrum disorders belong to the larger category of neurodevelopmental disorders.
Main signs of autism
finding it hard to understand what others are thinking or feeling. getting very anxious about social situations. finding it hard to make friends or preferring to be on your own. seeming blunt, rude or not interested in others without meaning to.
Barkley, PhD. “Children diagnosed with ADHD are not likely to grow out of it. And while some children may recover fully from their disorder by age 21 or 27, the full disorder or at least significant symptoms and impairment persist in 50-86 percent of cases diagnosed in childhood.
Sensory issues and sensory processing disorders are prevalent in people with ADHD. Although scientists are still researching the exact correlation, research has shown that kids and adults with ADHD are more likely than neurotypical people to experience sensory overload.
Thayer's study shows that the ADHD group of children had larger and more frequent variations. Fathers with ADHD will pass this code discrepancy to offspring. Barkley explains that the heritability of ADHD runs around 80 percent. Genetics account for 80 percent of the components that define ADHD.
Available evidence suggests that ADHD is genetic—passed down from parent to child. ADHD seems to run in at least some families. At least one-third of all fathers who had ADHD in their youth have children with the condition. What's more, the majority of identical twins share the ADHD trait.
