Chapter 1: Executive Dysfunction Explained

What exactly is executive dysfunction, particularly in the context of ADHD and autism? This exploration delves into the various categories of executive function, highlighting the specific challenges faced by individuals with these neurodivergent conditions.

In discussions within neurodivergent communities, particularly concerning autism and ADHD, the term "executive dysfunction" frequently arises. While we generally grasp its implications, the comprehensive aspects of executive functioning remain somewhat unclear, leaving many individuals unaware of the specific areas in which they encounter difficulties.

To clarify, I compiled a comprehensive list of executive functioning categories from various sources. These definitions often present overlapping skills, indicating that some areas might merge or interrelate. From my research, including insights from novellaprep.com and embrace-autism.com, I identified 16 primary domains of executive function.

The key areas of executive function include:

• Response Inhibition (self-control/impulsivity)
• Working Memory
• Emotion Regulation
• Task Initiation
• Sustained Attention
• Planning/Prioritization
• Organization
• Time Management
• Behavioral Flexibility
• Metacognition (awareness of one’s thought processes)
• Stress Tolerance
• Defining and Achieving Goals
• Observation
• Persistence
• Processing Speed
• Visuospatial Abilities (analyzing and integrating spatial relationships)

Individuals on the autism spectrum often face challenges with behavioral flexibility. Sudden changes can lead to significant distress, as many prefer predictable routines. This inflexibility can result in a unique form of anxiety linked to maintaining routines, potential sensory overload, or losing access to special interests.

On the other hand, those with ADHD typically face greater difficulties in areas like organization, task initiation, and planning. Deficiencies in these skills can lead to increased feelings of depression and lower daily functioning. Moreover, individuals with ADHD may experience heightened rates of addiction and binge-eating disorders, stemming from the trauma associated with societal judgment regarding their challenges.

For those who identify with both autism and ADHD, executive function issues may become even more pronounced. Although I self-diagnosed my co-occurring ADHD and couldn't afford a formal assessment, I took the Executive Skills Questionnaire (ESQ) to better understand my strengths and weaknesses.

The ESQ evaluates 12 areas of executive function, revealing my strengths in metacognition, organization, and sustained attention, while highlighting challenges in working memory, emotional control, and time management. This was unsurprising given my recent experiences with menopausal changes and a prolonged autistic burnout, which have adversely affected my working memory and emotional regulation.

In addition to the ESQ, I also completed the ESQ-R, which categorizes executive skills differently. Here are the condensed categories from this assessment:

• Plan Management: Planning and managing tasks effectively.
• Time Management: Estimating and allocating time appropriately.
• Organization: Maintaining systems and tracking information.
• Emotion Regulation: Managing emotions to achieve goals.
• Behavior Regulation: Exercising self-control and considering the consequences of actions.

My results from the ESQ-R echoed those of the original assessment, showcasing consistent patterns in my executive function capabilities. Determining whether autism or ADHD plays a more significant role in my specific challenges feels like an endless cycle of confusion.

While claims about the distinct executive function challenges associated with ADHD and autism are widespread, a recent study conducted by Canadian researchers in December 2023 titled "Do ASD and ADHD Have Distinct Executive Function Deficits?" suggested otherwise. Their findings indicated no significant comparative differences in executive dysfunction between children and adolescents with these conditions. However, the study did limit its scope to a few specific areas of executive function, which may impact its conclusions.

Given my experience with both conditions, I find it imperative to address how co-morbidity influences executive function evaluations. Through my research and assessment experiences, I have gained insight into my strengths and can better focus on my challenges.

It was refreshing to find assessments that acknowledge our strengths, as discussions surrounding autism and ADHD often fixate on deficits, neglecting the potential benefits that neurodiversity can offer to our communities.
