A child with autism may find it hard to express their emotions, and they may not use the common cues of conversation like gestures or eye contact. A child with ADHD, on the other hand, may talk non-stop, always interrupting and not really noticing how their words affect others.
ADHD is a neurodevelopmental condition whose hallmark signs include hyperactivity, impulsivity, and inattention. Autism is also a neurodevelopmental condition, but one characterized by social skills challenges like social interactions, communications, and repetitive behaviors.
Attention deficit hyperactivity disorder (ADHD) and autism can look a lot alike. Children with either one can be very active and impulsive, and can have trouble focusing and interacting with other people. In fact, it can be hard to tell the difference between the two.
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.
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.
Those with ADHD or other neurodevelopmental disorders are more likely to exhibit signs of sensory overload than those without these conditions. A child with sensory overload may react by throwing a temper tantrum, screaming, crying, kicking, or trying to hide.
ADHD meltdowns are sudden outbursts of frustration and anger that seem to come out of nowhere. If your child is struggling to control their emotions, there are ways to help them. For children with attention deficit hyperactivity disorder (ADHD), impulsivity can present in many ways.
Overstimulation is a state of feeling overwhelmed by the situation you are in. This might take the form of physical or emotional discomfort and feeling like your brain is frozen or you're unable to think or process anything that's happening.
Roughly two-thirds of children with ADHD have at least one comorbid condition, and autism is among those that commonly occur with ADHD. Some studies suggest that nearly half of autistic children also have ADHD.
Autism is very distinct from ADHD, but the core symptoms of ADHD-Combined type, i.e., attention deficit, impulsivity, and hyperactivity, would appear to also be features of autism. ASD and ADHD are neurobiological disorders characterized by similar underlying neuropsychological “deficits”.
Many adults and children living with ADHD never have had significant behavior problems; they have difficulty focusing their attention on necessary tasks and using working memory effectively, making ADHD a cognitive disorder, a developmental impairment of executive functions (EFs) — the self-management system of the ...
Sensory overload can happen to anyone, but it is more common in autistic people and people with ADHD, PTSD, and certain other conditions. It causes feelings of discomfort and being overwhelmed.
Hyperactivity with Sensory Disorders
Hyperactivity and impulsivity can be symptoms of a sensory disorder as well. A child who can't sit in his seat may be “seeking” more sensory input, or trying to escape an overwhelming sensation.
Some people with ADHD are very sensitive to touch and the feel of certain fabrics and tactile experiences, ie. the texture of some foods. These people find it difficult to tolerate tags in their clothes, the feel of specific foods in their mouths, scratchy or otherwise uncomfortable fabrics.
