Autism/ADHD & Fatigue

Executive Function Load:

Both ADHD and autism involve challenges with executive functioning – skills like planning, organizing, focusing, and switching attention. Tasks that are automatic for neurotypical people require more deliberate mental effort, which drains energy.

This constant mental juggling can lead to cognitive fatigue, as the brain is working overtime to stay organized and on task.

Sensory Processing Differences:

Many individuals with ADHD or autism have atypical sensory sensitivities. Everyday environments (noise, lights, crowds, touch, etc.) can bombard them with stimuli, forcing the brain to constantly filter and manage sensory input.

This near-constant state of sensory vigilance is exhausting – for example, loud noises or bright lights that others might tune out can be overwhelming and mentally draining over time.

Emotion Regulation & Masking:

Regulating emotions (like frustration, anxiety, or overwhelm) also consumes more energy. Autistic and ADHD people often engage in masking – suppressing or hiding their natural behaviours to fit in socially.

Masking demands continuous cognitive and emotional effort, which leads to profound exhaustion Over time, the stress of holding in true feelings or coping with frequent misunderstandings can result in what’s often called burnout, where the person feels mentally and emotionally spent.

Sleep Disturbances:

Both groups are prone to sleep problems that compound daytime fatigue. ADHD and autism are frequently linked with insomnia, irregular sleep cycles, or poor sleep quality (e.g. due to differences in melatonin regulation, hyperarousal, or racing thoughts at night).

Many struggle with falling asleep or staying asleep, and unrefreshing sleep means they start the day already depleted. Over weeks and months, chronic sleep deficit magnifies difficulties with concentration and energy during the day.

We help people with Autism/ADHD or AuDHD (or suspected) who are experiencing fatigue that is affecting their quality of life and/or the ability to sustain working or other activities that matter to them.

Our aim is to help people to understand that the role that neurodivergence plays in the complex picture of fatigue- recognising that it is not just a secondary symptom, but often a primary factor. From there, our programmes are bespoke and identify a meaningful and sustainable pathway forward for each person.

You do not need to have had a formal diagnosis to engage in one of our rehabilitation programmes to start easing the way that symptoms of fatigue are impacting your life.
