Executive Dysfunction and ADHD: Signs and What Helps

Short answer: Executive dysfunction means ongoing difficulty with executive functions: the mental skills you use to plan, stay focused, hold information in mind and stop yourself acting on impulse. It’s closely linked with ADHD,¹ but it isn’t a diagnosis on its own and it isn’t proof of ADHD, because depression, brain injury and lack of sleep can affect the same skills.²³⁴ Practical strategies, psychological therapy and, where ADHD is the cause, medication can all help.

What is executive dysfunction?

Executive functions are the mental skills that help you manage yourself and your tasks. In ADHD research, the ones most often discussed are working memory, planning, sustained attention and inhibitory control.¹

• Working memory: holding information in mind and using it, like remembering a phone number while you dial it
• Planning and organising: working out the steps to reach a goal, in the right order
• Sustained attention: staying with a task, especially one that isn’t interesting
• Inhibitory control: stopping yourself acting on impulse, and tuning out distractions so you can focus

“Executive dysfunction” isn’t a formal diagnosis. It describes a pattern of ongoing difficulties with these skills, and that pattern can have different causes.

Signs of executive dysfunction

Executive difficulties tend to show up in ordinary, everyday ways:

• Starting tasks: knowing exactly what you need to do but not being able to begin. See ADHD paralysis.
• Planning and prioritising: not knowing where to start on a big job, or doing the easy tasks first and leaving the important ones
• Managing time: underestimating how long things take, or looking up to find hours have gone. Research has found differences in timing and time perception in ADHD.⁵ See ADHD and time blindness.
• Working memory: forgetting what you walked into a room for, losing track of instructions, or losing your place halfway through a task
• Organisation: in adults with ADHD, this can look like losing keys and paperwork and finding it hard to organise tasks and activities⁶
• Staying on task: drifting off partway through dull tasks, or ending up with several half-finished jobs. The Better Health Channel lists finding it hard to sustain attention and to follow instructions or finish tasks among the signs of ADHD in adults.⁶
• Emotional regulation: feelings that build quickly and are hard to settle. Emotion dysregulation is common in ADHD throughout life and is a major contributor to impairment.⁷

Everyone has days like this. Executive dysfunction is when the difficulties are persistent and get in the way of work, study, relationships or running a household.

Executive dysfunction and ADHD

Neuropsychological studies show that ADHD is associated with difficulties in executive functions such as working memory, planning, sustained attention and inhibitory control, and with keeping performance consistent over time.¹ Brain imaging also shows that people with ADHD have less activation in brain regions linked to executive functions such as inhibitory control.¹ See the ADHD brain.

Not everyone with ADHD has the same profile, though. The Australian ADHD Guideline describes marked variation in how people with ADHD perform on neuropsychological tests: some have few difficulties across these areas, while others have many more.¹

That has two practical consequences. A normal result on cognitive testing doesn’t rule ADHD out, and executive difficulties on their own don’t rule it in. There’s no single test for ADHD; diagnosis involves a comprehensive assessment by a qualified clinician.⁸

Other causes of executive dysfunction

Executive difficulties aren’t specific to ADHD. Similar problems can come with:

• Depression, which can cause problems concentrating, reduced motivation and being less productive at work or study²
• Autism, some features of which overlap with ADHD⁹
• Brain injury: after an acquired brain injury, some people have problems with memory, concentration and planning or organisation, or with controlling their emotions³
• Lack of sleep, which can affect memory, attention and emotional regulation, and even short-term sleep loss can impair these functions⁴

These conditions can also occur alongside ADHD: in adults with ADHD, co-occurring conditions can include anxiety, depression, sleep difficulties, learning differences and autism.⁶ So executive difficulties can have more than one cause at once.

See a GP if executive difficulties are affecting your work, study or relationships, if they’re new or getting worse, or if they started after a head injury. A GP can help work out what’s behind them. If you’re feeling low or overwhelmed, you can call Lifeline on 13 11 14 or Beyond Blue on 1300 22 4636, 24 hours a day, 7 days a week. In an emergency, or if you or someone you know is in crisis, call 000.¹⁰

Practical strategies that help

Many strategies work by moving the load out of your head and into your surroundings, so you rely less on memory and willpower:

• Write it down. Use one calendar, alarms and a visible to-do list rather than trying to remember.
• Break tasks into the next step. Turn “do my tax” into “find last year’s return”, and set a timer for 10 minutes.
• Make time visible. Use timers and clocks you can see, and add buffer time before appointments.
• Build routines. Keep keys and wallet in the same place and do things in the same order each morning, so there are fewer decisions to make.
• Cut distractions. Put your phone in another room, turn off notifications and keep one tab open.
• Work alongside someone. Body doubling, or working next to another person in person or online, helps some people get started.
• Move your body. In adults with ADHD, a meta-analysis found exercise had a moderate benefit for inhibitory control, though the authors describe the evidence as preliminary.¹¹

Coaching can help you build these systems and stick with them. The Australian ADHD Guideline says ADHD coaching could be considered as part of a treatment plan for adults,¹² and the Better Health Channel describes coaching and skills-based supports as helping with organisation, time management, planning, prioritisation, goal setting and maintaining routines.⁶ For more ideas, see effective strategies for managing ADHD in daily life.

Therapy and medication

Cognitive behavioural therapy (CBT)

CBT is a psychological treatment that may help you develop strategies and skills for learning and managing your behaviour.¹³ For adults with ADHD, the Better Health Channel describes it as a way to develop practical strategies for managing everyday challenges.⁶

The Australian ADHD Guideline recommends that cognitive-behavioural interventions be offered to adults with ADHD. This is an evidence-based recommendation, although the guideline rates the certainty of the evidence as low.¹² Psychologists provide CBT, and your GP can talk to you about referral options.

Medication

For people with ADHD, medication can help with some of these difficulties. Stimulant medicines are thought to work by adjusting chemical messengers such as dopamine and noradrenaline, which play a role in behaviour, impulsiveness, attention and memory.¹⁴ The Australian ADHD Guideline notes that medication is the most effective treatment for reducing core ADHD symptoms, while non-medication treatments provide additional support with the day-to-day impact.¹²

Your doctor may suggest combining psychological approaches with medicine.¹³ Whether medicine could help depends on what’s causing your difficulties, so talk to your doctor or pharmacist about what’s suitable for you.

Frequently asked questions

What is executive dysfunction?

It means ongoing difficulty with executive functions, the mental skills you use to plan, stay focused, hold information in mind and control impulses. It describes a pattern of difficulties rather than being a diagnosis in itself.

Is executive dysfunction a sign of ADHD?

It can be. Executive function difficulties are common in ADHD, but people with ADHD vary a lot, and similar difficulties also occur with depression, brain injury and lack of sleep. A health professional can help work out the cause.

What does executive dysfunction feel like?

Often it feels like knowing what you need to do but not being able to start, losing track of time, forgetting what you were doing halfway through, struggling to prioritise, or drifting off before a task is finished.

How do you treat executive dysfunction?

It depends on the cause. Strategies that put structure outside your head, such as reminders, routines and breaking tasks into small steps, help many people. When ADHD is the cause, CBT, coaching and medication can also help.

Can ADHD medication help with executive dysfunction?

For people with ADHD, medication can reduce core symptoms and help with attention and impulsiveness, and it’s often combined with other approaches. Talk to your doctor or pharmacist about whether it’s suitable for you.
