ADHD and Chronic Fatigue

The Link Between Fatigue and ADHD

Fatigue is one of the often symptoms associated with ADHD. It is easy to overlook that since a lot of attention is placed on the more restless, frenetic, and impulsive side of the condition.

There is increasing, though not yet definitive, evidence of a link between chronic fatigue and ADHD in adults. There are likely other distinctive sources of fatigue, such as sleep difficulties, which are common to adults with ADHD, or any health conditions for which adults with ADHD might be at elevated risk due to poor health monitoring. Tiredness is also an effect of many prescribed stimulants as they wear off later in the day.

Why ADHD Can Cause Fatigue

There are a number of underlying reasons for the exhaustion often experience by individuals with ADHD. These include:

  • Cognitive load – This refers to the strain on one’s working memory. Working memory is one of the main areas of difficulty in adult ADHD. Other components of cognitive load include decision-making and emotional management. All of these processes guide behavior, including task management.
  • Sleep issues – Problems falling asleep or getting quality sleep are common with ADHD. Often the sleep cycle is shifted by several hours which can mean being out of synch with the way today’s world is designed to work.
  • Anxiety – ADHD is often accompanied by the comorbidities of depression and anxiety, both of which can leave you feeling exhausted.

So, if you have ADHD and are experiencing chronic fatigue, what can you do?
