Attention Deficit Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) are neurodevelopmental conditions that can often coexist. When both conditions are present, this is sometimes referred to as AuDHD (ADHD and Autism). Though, not a term used by doctors when giving diagnoses, people commonly use it to signify they have both conditions.
In this feature, the symptoms of ADHD and autism will be explored separately and then what the combination presents as.

Feeling unsure whether it’s ADHD, autism, or both can be overwhelming - especially when you’re not sure where to turn. Our experienced clinicians offer thoughtful, in-depth assessments tailored to you, helping you understand your symptoms and what comes next. Skip the uncertainty and long waits, and take a positive step forward today.

What are the symptoms of ADHD?
ADHD is a common neurodevelopmental disorder and symptoms can vary greatly between people but are typically grouped into three categories - inattention, hyperactivity, and impulsivity. This means they primarily affect attention, impulse control, and activity levels and symptoms mainly present and are evident before the age of 12, however in some cases they may not appear obvious before the age of 12.
Inattention symptoms of ADHD
If you have ADHD, you may struggle to maintain focus and stay organised, which can significantly affect academic performance, performance at work, and everyday activities.
Common signs include:
Difficulty focusing on tasks or conversations.
Frequently forgetting or misplacing items.
Trouble following through on instructions or completing tasks.
Easily distracted by external stimuli or irrelevant thoughts.
Difficulty staying organised and managing time effectively.
Hyperactivity symptoms of ADHD
Hyperactivity in ADHD is not just about being physically active; it also refers to a sense of internal restlessness which may present in the form of a 'busy brain'.
Common signs of hyperactivity in people with ADHD include:
Fidgeting or squirming.
Talking excessively.
Difficulty sitting still or staying quiet when expected.
Restlessness or a constant sense of being ‘on the go’.
Thinking about many things all at once.
Impulsivity symptoms of ADHD
Impulsivity refers to acting without considering the consequences.
If you have ADHD, you may:
Interrupt conversations or others’ activities.
Struggle to wait your turn.
Make decisions quickly without planning ahead.
Have trouble controlling emotions or reactions.
What are the symptoms of autism?
Autism Spectrum Disorder (ASD) is a developmental condition that primarily affects social interactions, communication, and behaviour. The symptoms are almost always present in early childhood, though they may not fully manifest until demands exceed capacity and start to cause impact on day to day life. The signs of autism can vary widely but typically include:
Social communication and interaction symptoms of autism
People with autism often have difficulty understanding and responding to social cues.
Some common signs include:
Struggling with understanding or using non-verbal communication - for example, gestures, facial expressions, tone of voice.
Difficulty maintaining eye contact or interpreting it in social situations.
Preference for direct or literal communication.
Challenges with small talk or forming friendships.
Limited understanding of social rules and expectations.
Repetitive behaviours and restricted interests
Autism is also characterised by patterns of repetitive behaviour and a strong focus on specific interests.
Los síntomas comunes incluyen:
Engaging in repetitive movements or behaviours - known as 'stimming'.
Intense focus on specific topics or hobbies.
A preference for routine and predictability, with distress when routines are disrupted.
Sensory sensitivities - for example, sensitivity to light, sound, touch, or smells.
The overlap between ADHD and autism (AuDHD)
While ADHD and autism are distinct conditions, they share many similar symptoms, which can make it difficult to distinguish between them, especially in people who may have both (AuDHD).
AuDHD (ADHD and Autism) reflect traits of both conditions.
Key symptoms of AuDHD
The cluster of the symptoms of AuDHD are a result of a combination of both ADHD and ASD.
1. Executive functioning challenges
If you have AuDHD, you may often experience significant difficulties with executive functioning, a cognitive process that includes planning, organisation, time management, and decision-making.
This may manifest as:
Inconsistent attention - you might find it hard to stay focused, jumping from task to task without completing them, which is characteristic of ADHD.
Difficulty organising thoughts - you may have a tendency to become overwhelmed with large amounts of information, making it hard to prioritise tasks, a trait shared with both ADHD and autism.
Time management difficulties - like ADHD, AuDHD can make it hard to judge time effectively, leading to procrastination or lateness.
2. Sensory sensitivities and overload
If you have AuDHD, you may experience heightened sensory sensitivity due to the combination of ADHD and autism symptoms.
This can include:
Overreacting to sensory stimuli - lights, sounds, textures, or smells that others might ignore can cause stress or discomfort. This is typical of autism.
Difficulty filtering sensory input - in addition to autism-related sensory challenges, if you have AuDHD, you may also struggle with ADHD-like distractibility, making it harder to tune out irrelevant stimuli.
3. Emotional regulation and impulsivity
Emotional dysregulation is a significant feature of both ADHD and autism, but in AuDHD, this can be more pronounced.
You may experience:
Cambios de humor - rapid shifts in emotional states, such as irritability or frustration, which can occur due to challenges in managing impulses and emotions.
Impulsivity - as with ADHD, people with AuDHD may act without thinking, leading to outbursts, impulsive decisions, or risky behaviour. Combined with the rigidity often seen in autism, these impulsive actions might appear unpredictable.
4. Social interaction difficulties
Social difficulties in AuDHD reflect traits from both conditions. While autism leads to struggles in interpreting social cues and establishing relationships, ADHD can contribute to impulsivity in conversations and difficulty maintaining focus in social settings.
Los síntomas pueden incluir:
Interrupting others - as seen in ADHD, a person with AuDHD might speak over others or struggle to wait their turn in conversations.
Difficulty understanding social norms - due to the social communication challenges of autism, you might not recognise appropriate conversational flow or cues, such as body language or tone.
Social fatigue - the demands of socialising might lead to burnout, as people with AuDHD may find it mentally exhausting to navigate social interactions.
5. Intense interests combined with distractibility
In AuDHD, you might experience both the narrow, intense interests often seen in autism and the distractibility of ADHD.
This can look like:
Hyperfocus on specific topics - you may become deeply absorbed in a specific interest or hobby, a hallmark of autism, but still be easily distracted by external stimuli or other topics, reflecting ADHD symptoms.
Difficulty switching attention - moving from one topic to another or shifting focus from a preferred activity can be challenging, even if you are interested in a different subject.
Puntos clave
The symptoms of ADHD and autism combined results in an experience which is unique to each person. The combination can create challenges in areas such as executive functioning, social interactions, sensory processing, and emotional regulation. Understanding these overlapping and distinct traits can help you get the right support, tailored to your needs.
Support for ADHD, autism, and AuDHD
If you recognise traits of ADHD, autism, or both, getting the right support can dramatically improve your quality of life. Here are a few options for support:
Clinical diagnosis and treatment
Getting a formal diagnosis from a qualified healthcare professional is the first step toward understanding your condition. For ADHD, medication such as stimulants may help with focus and impulse control, while autism may benefit from therapies focused on social communication and sensory management.
Therapy and support
Terapia cognitivo-conductual (TCC) - this type of therapy can help manage both ADHD and autism symptoms by addressing negative thinking patterns and teaching coping strategies.
Terapia ocupacional - for sensory processing difficulties and executive functioning challenges, occupational therapy can provide tailored strategies.
Coaching and life skills support - ADHD coaching can help with time management and organisational skills, while autism coaching may focus on social skills and self-regulation.
Educational and workplace adjustments
Both ADHD and autism may require adjustments in the workplace or educational settings.
Ejemplos incluyen:
Extended deadlines or reduced distractions.
Support with social interactions and communication.
Flexible schedules or breaks to manage sensory overload.
Building understanding and acceptance
Educating yourself and others about ADHD, autism, and how the combined presentation can look like is key. Support groups and community networks can provide a sense of connection, and understanding from family, friends, and colleagues is invaluable in creating an accepting environment.
Resumen
ADHD and autism are distinct conditions, but their symptoms can overlap significantly, especially when both are present together. Understanding the unique and shared symptoms of these conditions is crucial for seeking the right support and making informed decisions about treatment.
By seeking a formal diagnosis and engaging in therapy and support, you can better manage your symptoms, improve social relationships, and thrive in both personal and professional settings.

Preguntas frecuentes
¿Qué es AuDHD?
AuDHD es un término utilizado para describir a las personas que tienen una combinación de Trastorno por Déficit de Atención e Hiperactividad (TDAH) y Trastorno del Espectro Autista (TEA). Refleja la presencia de rasgos de ambas condiciones, resultando en desafíos y fortalezas únicas.
¿Existen tipos específicos de terapia que puedan ayudar con AuDHD?
Sí, varios tipos de terapia pueden ser beneficiosos para AuDHD. La terapia cognitivo-conductual (TCC) puede ayudar a manejar los síntomas al abordar patrones de pensamiento negativos y enseñar estrategias de afrontamiento. La terapia ocupacional ofrece estrategias personalizadas para las dificultades de procesamiento sensorial y los desafíos de funcionamiento ejecutivo. El coaching y el apoyo en habilidades para la vida, como el coaching para el manejo del tiempo en el TDAH o el coaching para habilidades sociales en el autismo, también pueden ser muy útiles.
¿Cómo se pueden ajustar los entornos educativos o laborales para alguien con AuDHD?
Los ajustes en entornos educativos o laborales pueden ayudar significativamente a las personas con AuDHD. Ejemplos incluyen plazos extendidos o reducción de distracciones para mejorar la concentración. También se puede proporcionar apoyo con las interacciones sociales y la comunicación. Se pueden ofrecer horarios flexibles o descansos para manejar la sobrecarga sensorial y prevenir el agotamiento.
¿Cómo se manifiestan las sensibilidades sensoriales en AuDHD?
En el AuDHD, las sensibilidades sensoriales pueden estar aumentadas. Puede que descubras que las luces, los sonidos, las texturas o los olores que otros apenas notan pueden causar un estrés o malestar significativo. Esto a menudo es difícil de manejar porque las personas con AuDHD también pueden tener dificultades con la distracción similar al TDAH, lo que hace más difícil filtrar la información sensorial irrelevante.
¿Qué tipo de grupos de apoyo están disponibles para AuDHD?
Los grupos de apoyo y las redes comunitarias desempeñan un papel crucial en la construcción de comprensión y aceptación para las personas con AuDHD. Estos grupos pueden proporcionar un sentido de conexión, permitiéndote compartir experiencias y estrategias de afrontamiento con otros que entienden tus desafíos únicos.
