In our extensive clinical experience, we often recognise the signs of attention deficit hyperactivity disorder (ADHD) in autistic children and adults.? A recent research study has confirmed that 48% of autistic children and adolescents are both autistic and ADHD (Kerns et al., 2021). Even if an autistic person does not meet the full diagnostic criteria for ADHD, they often have fragments of ADHD in their profile of abilities.??
??
Being autistic and ADHD is associated with significantly poorer cognitive performance and social/adaptive abilities compared to autism without ADHD. The combination may have a distinctive pattern of abilities and neurology compared to autism without ADHD. Those who have both characteristics are also more likely to have greater difficulties with executive and social processing and to develop emotional/behavioural challenges, especially externalising behaviour (Rosello et al., 2022).??

Hannah Gadsby (2022, page 267) describes their autism, executive functioning, and attention difficulties in her autobiography:?
The bit of the brain that is responsible for prioritising, integrating and sorting out all the incoming – is just a bit sh** at its job. My brain is a Ferrari with bicycle brakes, it has no filing system or what medical professionals call ‘executive function.’?
?It’s not so much that I have a deficit in attention. I take it all in. I pay attention to everything. If anything, it’s attention overload. The deficit is working out what is important and dealing with it in a timely manner.?

New conceptualisations of ADHD?
Clinicians and researchers seek patterns of abilities and behaviour associated with ADHD and develop new conceptualisations. Two new conceptualisations of ADHD have recently been identified: Emotion Regulation Difficulties (ERD) and Sluggish Cognitive Tempo (SCT).?
Emotion Regulation Difficulties?
Forty to fifty percent of ADHD children have emotion regulation difficulties (ERD) characterised by anger, irritability, and low distress tolerance. (Faraone et al. 2019). There seems to be an emotional reaction without reflection, inhibiting the effectiveness of behaviour management strategies and cognitive behaviour therapy (CBT). There is also the risk of greater social rejection by peers due to episodic explosive reactions, family distress, reduced quality of life and educational and occupational outcomes. ERD may be linked to hyperactivity and impulsivity and may be a diagnostic subtype (Martel, 2009).?
Sluggish Cognitive Tempo?
Sometimes, a new term is associated with interesting imagery. Sluggish Cognitive Tempo (SCT) or Cognitive Disengagement Syndrome (CDS) has a distinct cognitive and motor pattern and occurs in 25-40% of ADHD teenagers and young adults (Becker et al., 2016). The characteristics include excessive daydreaming, being lost in a mental ‘fog’ underactive and slow moving. SCT is associated with social withdrawal and internalising symptoms, especially depression and is linked to inattention.?
There is discussion in the research literature as to whether ERD and SCT should be considered as part of the ADHD diagnostic criteria. Both descriptions could also be applied to autistic individuals with ADHD.?
The neurology of autism plus ADHD?
Research on the neurology of autism plus ADHD has confirmed that the combination is not simply an overlap of the associated neurological structures but a unique frontoparietal brain dynamic (Watanabe & Watanabe, 2023) with a distinct and robust neuroanatomical signature of widespread increases in cortical thickness and certain decreases in surface area (Bedford et al., 2023).??

The experience of autism plus ADHD?
Autism and ADHD have many distinct characteristics. When autism and ADHD combine, the characteristics of both neurotypes can create considerable confusion and internal conflict as to whether autism or ADHD is dominant in a specific situation. Examples are:?

Noah described his contrast between both and subsequent challenges:?
??
One of the biggest challenges I face is that my brain often works in non-linear ways. I can see connections and patterns that others miss, and I have a natural ability to think creatively and come up with unique solutions to problems. But at the same time, I also struggle with organization, executive functioning, and other challenges that can make it difficult for me to bring my ideas to fruition.?
??
An AuDHDer, their family members and teachers often have difficulty determining the dominance of an autistic or ADHD characteristic and how a compromise or resolution can be achieved. They will need access to expertise in both neurotypes.?

Autism plus ADHD and mental health?
Autistic plus ADHD children and adolescents are more likely to experience anxiety, depression, and other mental health conditions than those who have one neurotype (Casseus et al., 2023). There is also an association between autism, ADHD and substance abuse (Butwicka et al., 2017; Ressel et al., 2020) and suicide (Kolves et al. (2021).???
Autism plus ADHD and depression?
A recent study of those who are autistic and have ADHD has found a prevalence of depression at age 19 of 23% and 44% before the age of 30 (Thapar et al., 2023). The risk factors for depression in ADHD and Autism, according to the Thapar et al. study are:?
1: Genetic liability?
Both ADHD and autism are highly heritable and parents of those with ADHD and Autism have heightened rates of depression.?
2: Trauma?
The characteristics of both conditions increase the likelihood of trauma when combined with social-environmental stressors, which increase depression risk.?
3: Social-environmental mechanisms?
Friendship quality, peer problems, being victimised, loneliness, and lack of social support networks can contribute to depression.?
4: Academic competence?
Sluggish Cognitive Tempo (SCT) can lead to low academic achievements and low self-esteem, which may lead to depression.?
5: Other conditions?
This can include anxiety and alexithymia and the effects of emotion regulation difficulties (ERD) leading to emotion dysregulation and feelings of intense despair and suicidal ideation.?
?
Artificial Intelligence (AI)??
In the future, Artificial Intelligence (AI) tutors may help students who are autistic and ADHD to achieve greater academic success. They are often more patient than a human teacher and can incorporate data from cognitive assessments, learning profiles and personality to create an individualised curriculum. There is no waiting for teachers with real-time feedback, and AI can adjust the curriculum based on past and current performance. Another advantage is that you do not have to put your hand up in front of 30 students to ask for help.?

Where to from here?
Our Event, Autism, ADHD and Executive Function, will be webcast on the 10th of May. More information on the webcast is available using the following link. The event is very similar to our previous Event, Autism and ADHD, it is updated with new research. If you attended Autism and ADHD, and wish to attend this event you qualify for a 50% discount.?

8 个月I'm autistic/adhd and relate to a lot of what you describe. I would add insomnia to your list as it is really common among our AuDHD group.? I also have alexithymia, aphantasia, and sdam, and have met several others that deal with those issues too. The (aphantasia + sdam) research is still in its infancy, but I meet a lot of AuDHDers in both online groups that I'm a part of. https://www.spectrumnews.org/news/genome-scan-spots-common-variant-differences-between-autism-and-adhd/
Founder, Brainchild Developmental Program Limited - Programs that give neurodevelopment a second chance.
8 个月ADHD and autism have been described to be "comorbid" conditions" for many decades. They are collections of behaviours or symptoms, as observed. The overlap is not surprising as they are both developmental conditions. As such, they reflect the influence on the maturation of the brain. This means that all neurological function can be affected. It is the persistence of brain function left active from pre birth and early life that is the limiting factor. The person's neurodevelopmental profile may or may not match the labels of autism or ADHD or indeed dyslexia, dyspraxia, and the many developmental labels The aspects of the patchy developments that caused issues can be helped.
