Ableism

Accommodations

Adaptive vs Maladaptive

When a person develops a particular behavior in order to cope with difficult situation, that behavior tends to fall into 2 categories: either adaptive or maladaptive.

Adaptive: adjusting to prompting stimuli in a way that is effective for the long term & does not create added difficulty.

Maladaptive: According to this educational paper from Columbia University, a maladaptive behavior “may work in the heat of the moment or for short-term relief, but ultimately lead to more stress and damage. This is because these strategies fail to reduce negative affective states and do not successfully maintain or increase positive affective states.”

ADHDAttention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder, also known as ADHD, is largely considered by the neurodiversity community as a neurotype. It is defined by the clinical psychology & medical community as a neurodevelopmental disorder (in my opinion, these things can be true at the same time).

In previous years, there were considered to be 2 separate diagnoses: ADD (attention deficit disorder) & ADHD. Now, ADD is no longer used and instead ADHD is used.

According to the DSM-V, the book which clinicians in the US reference for diagnostic criteria, ADHD is defined in the following ways:

  • Under the umbrella of Neurodevelopmental Disorders
  • Qualified as mild, moderate or severe
  • Symptoms must be present before age 12

Types: inattentive/distractible, impulsive/hyperactive, or combined.

Inattentive Type

  • “poor listening skills”
  • “losing items easily”
  • easily sidetracked
  • forgets daily activities
  • lacks ability to complete various tasks
  • avoids tasks which require concentration
  • fails to focus on details/makes “thoughtless” mistakes easily

Hyperactive Type

  • displays signs of impulsivity
  • struggles to sit still, refrain from squirming, “marked restlessness”
  • appears to be “driven by a motor”
  • lacks ability to engage in activities in a quiet manner
  • “overly talkative”

Combined Type: expresses symptoms of both types of ADHD for a period of 6 months or more

(source for summary of DSM-V definition)

From my understanding as a clinician in the neurodivergent space, I see that our understanding of ADHD is rapidly growing & changing in ways the DSM-V has yet to acknowledge.

Sonny Jane, aka Lived Experience Educator, as well as many others in the community describe the dimensions of ADHD in alternative ways. I think this can be super helpful to consider alongside the approach of the DSM-V when it comes to diagnosing & understanding ADHD.

  • attention differences
  • internal hyperactivity
  • external hyperactivity
  • differences in time perception
  • impulsivity
  • executive functioning differences
  • sensory & stimulation.

What do I mean by “dimensions?” My definition is that each dimension represents an aspect of ADHD. In order to have ADHD, one must have symptoms within each dimension. However, the severity of those symptoms within those dimensions varies quite a bit dependent on the individual.

Here is a visual representation of this concept, created by Sonny Jane.

Many of us reject the idea of diagnostically qualifying the severity of ADHD, as it is something that can be expressed in varying ways over time, dependent on co-ocurring diagnoses & neurotypes, and differing life experiences. As a clinician myseld, I see ADHD as a lens through which an ADHDer’s mental health is expressed, and that that expression can look different depending on the state of their well being.

Many individuals have a combination of ADHD & autism, also known as AuDHD.

Many theorize that genetics play a role when it comes to the occurrence of ADHD & autism. I have seen this in my experience & research, you often times see ADHD & autism occurring in families. For example: maybe one sibling has ADHD, the other autism, and one of the parents have AuDHD.

ADHD Paralysis

Alexithymia

ARFID Avoidant/Restrictive Food Intake Disorder

The difference in someone with ARFID and a “picky” eater is essentially the severity of the impact of the person’s eating habits. As described by Walden Eating Disorders, some of the things to look for are significant weight loss/struggle to maintain a healthy weight, as well as a change in psychosocial functioning.

In my experience as a clinician to several folks with ARFID, it is a disorder which is something that can develop/increase/flare with stress. For instance, choosing a meal requires several things:

  • First, for the person to identify their hunger cues (something that many neurodivergent people struggle with)
  • Then the decision making part of the process (which can feel like a demand & be very hard if someone is experiencing demand avoidance)
  • Then trying to decipher if the food feels safe or not which at times can be unpredictable
  • Then the executive functioning of putting the meal together/organizing how you will get the food
  • Then eating the food & hoping you will like it, as sometimes eating food you don’t like or want can be very dysregulating to someone with a sensitive nervous system/sensory processing difficulties.

On the flip side, safe foods just in general are very regulating can be helpful to give consistency & reliability for autistic people, which are things that we need to thrive.

See why a neurodivergent person might avoid eating?

If you are noticing an strong impact on your life/your loved one’s life due to selective eating habits, I’d recommend speaking to a professional who is versed in ARFID.

Treatment for ARFID can include things such as nutritional assessment, counseling support, medical care and feeding therapy. In my experience some of the best support can be 1. Reducing demands around food as much as possible, this includes allowing safe foods at all times 2. Creating a list of safe foods (not foods they HAVE to eat, but just a way of having them documented to help visualize choices) 3. Working to improve interoceptive awareness

RD’s (registered dieticians) for Neurodiversity have some great education & resources on understanding ARFID & neurodiversity.

Aphantasia

The inability to “picture” things in one’s mind. For instance, if I say think of an apple, a person with aphantasia would struggle to visualize one in their mind.

Applied Behavioral Analysis (ABA)

Overall this is a nuanced, difficult and very important issue in the autistic community, especially when it comes to autistic folks of intersecting marginalized identities. I highly encourage you to further educate yourself on the topic. I will provide a brief summary of what insight I have here. And for more resources, including the history & ethics of ABA, folks who are working to change ABA, & where to find alternatives to ABA, click here.

I cannot overstate: ABA can be & has been extremely harmful for many autistic folks.

There is a large number of autistic individuals who report having experienced a high level trauma due to ABA, and that cannot & should not be dismissed. Because of this, many folks in the autistic community believe that both ABA and behaviorist approaches should be altogether abolished.

Now, there are some folks who try to honor the trauma ABA has caused and want to use that information to create neuroaffirming, positive change in the field of ABA. I myself have connected with providers who are autistic themselves & working in the field of ABA (mostly running their own, very small practices) and those are the people I believe are going to bring about these much-needed changes. I have also found these folks are VERY much in the minority & rarely if ever given space to voice their concerns in places such as professional ABA conferences. This illustrates to me how to the larger ABA system is still very much ableist & an unsafe space for autistics.

It is extremely common for larger ABA clinics to require 20-40 hours a week of ABA therapy, which is something I would never, ever recommend subjecting anyone to. No matter how “neuroaffirming” they may claim to be. There are also still many folks in ABA who believe it to be a form of “treatment” for autism, and that is not an appropriate claim to make. In the world of ABA academics & trainings, there also remains a severe lack of centering autistic voices, which I think is a big part of the problem.

I hope to have a podcast episode on this soon. I will link it here when that is done!

AuDHD

I am working to expand my definition of this neurotype, however in the meantime this is a great article that explains AuDHD further.

Augmentative and Alternative Communication (AAC)

Autism

Autism is is considered by the neurodiversity community as a neurotype. It is defined by the clinical psychology & medical community as a neurodevelopmental disorder (in my opinion, these things can be true at the same time).

According to the DSM-V, the book which clinicians in the US reference for diagnostic criteria, autism, which they call Autism Spectrum Disorder, is defined in the following ways (everything in quotes below is taken directly from the DSM-V text)

  • Diagnosed by levels of 1, 2 or 3 dependent on “severity” & client’s “level of functioning.”
  • Must specify as to whether or not intellectual disability is co-occuring
  • Must specify as to whether or not language impairment is co-occuring
  • Must specify as to whether or not catatonia is co-occuring
  • Must specify if associated with a known medical or genetic condition or environmental factor

The DSM-V madates that diagnosed autistic individuals must also have symptoms in the following areas:

  • A. “Persistent deficits in social communication and social interaction across multiple contexts”
  • B. “Restricted, repetitive patterns of behavior, interests, or activities”
  • C. “Symptoms must be present in the early developmental period”
  • D. “Symptoms cause clinically significant impairment”
  • E. “These disturbances are not better explained by intellectual disability”

I believe this article provides a great breakdown of the DSM-V definition of autism to provide both critique & context. It was written by psychologists who are they themselves autistic.

As more & more autistic folks are openly sharing their experiences & contributing to the community as a whole, our definition of autism is shifting in ways the DSM-V has yet to recognize.

The way many of us choose to define autism is through a circular spectrum (pictured below) that is commonly comprised of various dimensions. I will say, there is variance in how some people define these dimensions.

What do I mean by “dimensions?” My definition is that each dimension represents an aspect of autism. In order to be autistic, one must have symptoms within each dimension. However, the severity of those symptoms within those dimensions varies quite a bit dependent on the individual.

However they are all virtually the same concepts, just titled & divided differently at times. To me, the infographic below is the most accurate definition of the varying dimensions. But I digress:

Dimensions of autism that are widely accepted by autistics with lived experience are most typically comprised of:

  • sensory processing
  • language differences
  • perception differences
  • executive functioning
  • motor skills
