There is a common link between attention deficit hyperactivity disorder (ADHD) and fatigue. Though the exact reason for the connection is unknown, many people with ADHD will experience mental or physical exhaustion that can lead to burnout if left unaddressed,
This article will provide information on ADHD fatigue, potential causes, ADHD and burnout, and ways to address fatigue.
Can ADHD Make You Feel Tired?
There is a strong correlation between ADHD and tiredness or fatigue, and people with ADHD often report experiencing more tiredness, stress, and fatigue than those without it. Some people also experience central fatigue syndrome, which causes tiredness and long-term fatigue. Conversely, those with central fatigue syndrome are often found to have ADHD symptoms.
Fatigue looks and feels different for everyone, and it can be mental or muscular and result from lack of sleep or depression.
Fatigue Is a Warning Sign
Fatigue is one of the ways the body signals a warning. Experiencing fatigue is your body's way of telling your brain it needs to rest.
The Relationship Between ADHD and Sleep
What Does ADHD Fatigue Feel Like?
ADHD fatigue can bring feelings of physical and mental exhaustion and difficulty sleeping. Some people also experience pain and less awareness of body movements. Periods of worsened or more intensified ADHD symptoms can make it difficult to relax and get rest.
For many people with ADHD, fatigue feels overwhelming. Competing tasks and priorities become challenging to manage, and it's common to be distracted and forgetful and to struggle with staying organized and on track.
How the ADHD Brain Is Wired Differently
What Causes ADHD Fatigue?
There are varying possible reasons why people experience ADHD fatigue, including other co-occurring disorders, medication, or burnout from managing symptoms.
One possible cause of ADHD fatigue is the association between hypermobility spectrum disorders (HSD) or hypermobile Ehlers-Danlos syndrome (hEDS) and ADHD. Though a person can have HSD or hEDS without ADHD, the two are often linked. HSD and hEDS often cause sleep problems and overall fatigue.
It is also common for people with ADHD to experience central fatigue syndrome (CFS). CFS occurs when there is increased plasma tryptophan in the brain, which causes feelings of tiredness and overall fatigue.
ADHD medications can also cause fatigue or drowsiness in some people, and for others, not being able to "turn off" their brains can cause difficulty sleeping and tiredness throughout the day.
ADHD and Brain Fog
ADHD and brain fog have similar symptoms. Distractibility, trouble organizing thoughts and tasks, and losing track of conversations and items are commonly experienced by those with ADHD as well as those with brain fog due to other conditions, like long COVID(symptoms that persist for an extended period of time after having had COVID-19), illness, or lack of sleep.
For some people who have never experienced ADHD symptoms before, sudden brain fog is likely due to another cause, such as diet, medication, or illness. Talking with a healthcare provider is the best way to determine the cause of brain fog. A provider can help you understand any factors contributing to brain fog through psychological and physical testing and a complete medical history.
ADHD Burnout
It's common for adults with ADHD to overcompensate for their difficulties with concentration, organization, and time management by overly focusing on tasks and work responsibilities to the point of exhaustion or even burnout. People with ADHD often find it difficult to relax or take breaks and are therefore at higher risk of overwork or hyper-focusing on tasks.
It can also be difficult for people with ADHD to manage life responsibilities, like parenting and managing appointments. These responsibilities can be taxing and difficult to organize which can feel exhausting.
Adult ADHD and Sick Leave
Adults with ADHD are at higher risk of exhaustion and burnout and take twice as much sick leave as their peers.

Other, Similar Symptoms
People with ADHD have a hard time staying focused and often have to work harder than others to complete tasks, stay on track, and accomplish goals. This extra work can lead to ongoing stress and difficulty coping. ADHD also often leads to marital problems, difficulty on the job, financial issues, and other challenges.
People with ADHD also often report feeling sensitive to criticism, especially at work. Ongoing criticism can be tiresome and lead to burnout as well. For some people, being understimulated can lead to boredom, which may appear as fatigue.

- Avoid things that trigger or worsen symptoms.
Summary
Fatigue is a common symptom in those with ADHD. Fatigue often brings tiredness and stress and can lead to burnout. Though the exact cause can be unknown and vary from person to person, ADHD-related fatigue may be due to other coexisting disorders, medication, or burnout from managing ADHD symptoms. Using organizational tools and techniques can help prevent fatigue and avoid burnout.
