ADHD
Attention-Deficit/Hyperactivity Disorder, often known as ADHD, is a neurodevelopmental condition that can affect attention, activity levels, impulsivity, organisation and everyday life. ADHD and autism can also co-occur, so understanding the overlap can help people receive the right support.
What is ADHD?
ADHD is a neurodevelopmental disorder characterised by persistent patterns of inattention, hyperactivity and impulsivity that are more significant than expected for an individual’s age.
ADHD can affect both children and adults and may impact areas of life such as school, work, relationships, home life, organisation and everyday tasks.
Inattention
Difficulty staying focused, being easily distracted, making careless mistakes, losing items or struggling to complete tasks.
Hyperactivity
Restlessness, fidgeting, difficulty sitting still, needing to move often or feeling constantly “on the go”.
Impulsivity
Acting without thinking, interrupting others, finding it difficult to wait, or making quick decisions without considering consequences.
Different presentations of ADHD
ADHD can present in different ways. Some people mainly experience inattention, some experience more hyperactive and impulsive traits, and many people experience a combination of both.
ADHD and Autism: Co-occurrence and Overlap
ADHD and autism are both neurodevelopmental conditions. They are separate diagnoses, but they can co-occur, meaning a person may be autistic and also have ADHD.
They can share some overlapping features, including differences with attention, regulation, sensory processing, routines, social interaction and managing everyday demands.
Key differences between ADHD and autism
- Social interaction: Autistic people may experience differences with social communication and understanding social cues, while people with ADHD may be socially active but struggle with impulsivity in social situations.
- Focus and attention: ADHD is often linked with difficulty regulating attention, while autism may involve deep focus on specific interests or routines.
- Sensory sensitivities: Sensory differences are commonly associated with autism, but people with ADHD may also experience sensory overload, especially in busy or overstimulating environments.
Common Signs of ADHD in Autistic People
When someone is both autistic and has ADHD, some behaviours may overlap. This can sometimes make it harder to understand which needs relate to ADHD, autism, or both.
- Impulsive behaviour: Difficulty controlling impulses, interrupting, acting quickly or engaging in risky behaviour.
- Difficulty with focus: Finding it hard to stay engaged with activities that are not interesting or motivating.
- Restlessness: Fidgeting, needing movement, difficulty relaxing or struggling to sit still.
- Mood fluctuations: Emotional outbursts, frustration, overwhelm or difficulty regulating emotions.
Diagnosis and Assessment
Diagnosing ADHD in autistic people can be complex, as some ADHD traits can overlap with autism-related traits. A thorough assessment by experienced healthcare professionals is important.
Assessment may include:
- Developmental history: Gathering information about milestones, behaviours, family history and early development.
- Standardised testing: Questionnaires, rating scales and psychological assessments to explore ADHD and autism traits.
- Observation and interviews: Speaking with parents, carers, teachers or the individual to identify patterns across different settings.
It is important that professionals understand both ADHD and autism so that an accurate diagnosis and suitable support plan can be developed.
Support and Strategies for Managing ADHD and Autism
For people who are both autistic and have ADHD, support should be tailored to the individual. Strategies often work best when they consider sensory needs, communication preferences, routines, emotional regulation and executive functioning.
- Medication: Some people may be prescribed medication to help manage ADHD symptoms such as focus, impulsivity or hyperactivity. This should always be discussed with a healthcare professional.
- Structured routine: Predictable routines, visual schedules, reminders and timers can help reduce anxiety and support transitions.
- Sensory management: Sensory breaks, quiet spaces, noise-cancelling headphones, movement opportunities or fidget tools may help with regulation.
- Social skills support: Some people may benefit from support to understand social cues, manage impulsive responses and build confidence in social situations.
- Educational support: Schools and colleges may need to provide tailored support, reasonable adjustments and, where appropriate, an Education, Health and Care Plan.
- Parent and carer support: Families may benefit from advice, training, peer support and practical strategies to support both ADHD and autism needs.
Understanding the whole person
ADHD and autism are both complex conditions. Understanding how they overlap, and how they differ, can help ensure people receive support that reflects their individual strengths, needs and experiences.
With the right support, understanding and adjustments, autistic people with ADHD can thrive and lead fulfilling lives.
