Executive functions (EFs) encompass a range of cognitive processes such as working memory, selective attention, planning, and inhibitory control. EF processes are governed by the prefrontal cortex, a region of the brain only found in primates such as humans and apes. The prefrontal cortex plays a central role in:

• Information processing

• Cognitive flexibility

• Decision-making

• Forethought

• Time management

• Planning/organization

• Learning from consequences

• Emotion regulation

• Task motivation

• Working memory/reconstruction of information

Collectively, these metacognitive processes constitute what we know as EFs. Similar to the role of an executive within a company, EFs are responsible for receiving, processing, and disseminating information. Their core functions are to self-regulate and inhibit behaviours.

What is EF Impairment?

Many mental health disorders, including attention deficit and hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and traumatic brain injury (TBI), among others, are characterized by deficits in EF. Virtually all EFs can be impacted in individuals with ADHD. For inattentive subtype of ADHD, individuals can commonly experience difficulties with organization, sustained attention, attention to details, frequently losing items, and time management. For hyperactive subtype of ADHD, individuals can commonly experience restlessness, blurting out answers to questions, interrupting others, difficulty waiting one’s turn, and difficulty with staying seated. For combined inattentive and hyperactive subtype of ADHD, individuals commonly experience a combination of these challenges.

Can EF Impairment be Treated?

Yes! Fortunately, EF impairment can be managed and improved with the right strategies and supports. While there is no one-size-fits-all approach, the following interventions and strategies have been shown to be beneficial:

• Medication and supplements - Medication is a first-line treatment for EF impairment, with the most frequently prescribed medications being stimulants and antidepressants. In addition, supplements such as Omega 3-6-9 are also commonly used to treat EF difficulties. For specific information and guidance on medication or supplements, be sure to consult with your physician.

• Cognitive Behavioural Therapy (CBT) - CBT has the most evidence demonstrating its effectiveness in alleviating EF impairments by enhancing cognitive processes, improving problem-solving, and promoting adaptive behavioural strategies.

• Mindfulness meditation - Meditation has been directly associated with reduced EF impairment within the research literature. Individuals who engage in regular meditation exhibit more developed brain regions associated with EF as compared to non-meditators.

• Accommodations - Accommodations are ways that environments can be adapted to help achieve one’s potential and perform at the same level as one’s peers. Whether at work or school, research shows that accommodations help individuals with EF impairments to navigate organizational and functioning challenges.

• Practicing good self-care - Good self-care can play a vital role in supporting individuals with EF challenges by providing a structured routine and stress reduction strategies, including adequate sleep, good nutrition, and movement.

• Exercise and movement - Regular movement and exercise have been shown to be highly beneficial for individuals with EF impairment. Physical activity can enhance cognitive functions, promote better focus, and reduce symptoms such as impulsivity,
