In this post, I discuss ADHD's intersections with three common co-morbid disorders and/or neurotypes and how understanding overlapping symptoms and traits can in turn help educators accommodate these students in social-emotional situations. Comorbidity is defined as more than one physical or mental health disorder co-occurring in the same person, as well as the effect that secondary conditions might have on one primary condition, in our case ADHD (Cucunic 2021). Three common disorders that co-occur with ADHD include autism spectrum disorder, anxiety disorder(s), and sensory processing disorder. Although these three disorders have numerous symptoms that affect all aspects of the child's life (that could be turned into an entire research project itself), I will specifically focusing on differences in regulating emotions and social communication.
Autism Spectrum Disorder (ASD)
Although the DSM-V lists ADHD as an exclusion criteria for ASD, 30-50% of people with ASD show symptoms of ADHD, and 2/3 of those with ADHD show symptoms of ASD (Davis and Kollins 2012, Leitner 2014); both disorders affect the central nervous system: a region responsible for "movement, language, memory, and social and focusing skills" (CHADD). The main difference between the two disorders is that ADHD is characterized by differences in the regulation of attention, impulsivity, and emotions, ASD typically manifests as "core social dysfunction and restrictive-repetitive behaviors" (Leitner 2014). When these conditions co-occur or a student shows traits of both (whether they are diagnosed for neither, one, or both), they shape the child's social-emotional experiences in significant ways. Children with ASD might have language differences (often called "delays") or difficulty reading both body language and social cues, as well as in their responses to and processing of sensory stimuli (e.g., textures in clothing and food). Autistic children may also interpret figurative language literally, avoid eye contact, isolate themselves, and/or engage in self-stimulatory behaviors (i.e., stimming) (CHADD, Leitner 2014). Children with ADHD but not ASD can typically read social cues if they are successful in focusing on them. However, inattention, emotional dysregulation, or overstimulation during conversations makes this difficult, as do issues with impulsivity in making them appear rude and/or socially awkward (HowToADHD, CHADD). Children with ADHD, like their autistic counterparts, also sometimes engage in stimming behaviors for the reason of managing external sensory information.
When ADHD and ASD traits are co-morbid in a child, the child is likely to exhibit impulsivity and inattention coupled with social/communication differences and sensory issues. Additionally, children with ADHD, ASD, or both "could not be distinguished from one another" in their "emotional recognition" and that neurodivergent students "used lower levels of social perspective taking coordination in their definition of problems, identification of feelings, and evaluation of outcomes" (Leitner 2014). Research has also shown that low dopamine levels, inattention, and impulsivity can make students with ADHD appear self-centered or narcissistic (Edge Foundation). This is not to say that a child with ADHD and/or ASD do not have empathy for others; this is a dangerous stereotype that prevents us from meeting our students' actual needs and viewing their traits and capabilities from an asset-based perspective (Rudy 2020). This misunderstanding also prevents us from examining how normed, arbitrary (read: neurotypical) standards for socializing and managing students' social-emotional health may not work for some neurotypes, and that the greater problem is actually a lack of societal flexibility and acceptance (Autism Self-Advocacy Network).
If a child with ADHD has co-morbid ASD or shows traits of ASD, it is important to accommodate a child's social-emotional needs in an inclusive way that does not fault the child. It's important for educators to view their students as both individuals separate from their dis/abilities and as individuals inextricable from their ASD and/or ADHD, understanding that this inextricability is in no way negative. Educators must know their students' specific social, emotional, and sensory profiles, their unique interests and communication styles, in order to accommodate them in inclusive (e.g., UDL) settings. Making weighted blankets and sensory toys available and varying the noise/light levels in the classroom, for instance, will help children with traits of ASD and ADHD to feel more comfortable in that environment and mitigate the effects of sensory overload on social interactions with peers (Children's Hospital of Philadelphia). Additionally, encouraging other students to use concrete language in social and academic interactions, creating a culture of unconditional patience and inclusion in the classroom (a difficult process which I discuss more in-depth in Interventions), using social stories (in a non-coercive, non-ableist way), and talking through social behaviors with children can help them process stimuli (e.g., their peers' behaviors) and make sense of their environments.
- children with an anxiety disorder ... experience more than a general lack of focus or a restless response to boredom. Their anxiety and worry are clear-cut, often focusing on specific situations or thoughts. They may seem tense, irritable, tired, or stressed out. They may not sleep well, and may even experience brief panic attacks -- involving pounding heart, difficulty breathing, nausea, shaking, and intense fears -- that occur for no apparent reason. While their school performance may be equivalent to that of children with ADHD alone, they tend to experience a wider variety of social difficulties and have more problems at school than children with ADHD alone. (2004)
People with ADHD are often bullied, feel that they don’t fit in, struggle academically and socially in school, and are admonished by adults for behaviors over which they have little control. The body’s chronic stress response is commonly referred to as the “fight or flight” response. Another name for it is “sympathetic arousal,” because it is an activation of the sympathetic nervous system. Sympathetic arousal is the body’s involuntary response to danger and causes adrenaline and cortisol to rush through the body, heart rate to increase, muscles to become tense. If this response happens repeatedly -- as it does for individuals with ADHD navigating daily disappointments, admonishments, and blows to their self-esteem -- the body learns to treat everything it encounters as a dangerous threat. Over time, it creates fixed action patterns in the body’s tissues, such as habitual muscle tension (clenching jaw or raised shoulders), digestive distress, and neurons that fire the same way repeatedly (defensive behavior patterns). All of these are signs of dysregulation. The nervous system has learned to respond to past events as if they are happening in the present. (2020)
If a child is diagnosed with or suspected to have ADHD, an anxiety disorder, or both, it's crucial for educators to show patience and to give children what they need. Children with ADHD and high levels of anxiety must be made to feel safe in their classrooms and find a sense of belonging. Establishing classroom routines, providing quiet work time and sensory-friendly spaces, supporting and monitoring social interactions, and being consistent and restorative in terms of behavior management are some examples of interventions for helping these children feel welcome in the classroom.
