What Do Comorbidity Studies Address
While the DSM-4 and ICD-10 give mutually exclusive diagnoses of ADHD and ASD, the DSM-5 mentions each condition in its description of the other, admitting the possibility of comorbidity.
Some studies have reported structural differences in attentional functions between ASD and ADHD patients, while others suggest these disorders present identical deficiencies .
Barnard-Brak reported varying ability to distinguish individuals with ASD from those with ADHD on the basis of their performance on different cognitive tasks that assess sustained attention. However, the rapid letter naming task, which is thought to predict surface reading ability and other reading skills, did reveal significant differences between ASD and ADHD children: the former spent more time on the task and performed better. Thus, the interpretation of performance on cognitive-attentional tasks evaluating sustained attention requires special caution to avoid confusing the two disorders. This study also highlighted the effect of environment on the performance of attentional tasks by those with ASD: the setting under which individuals complete diagnostic tests can greatly influence results.

Responding To Changes In Environment
Children with ADHD tend to become quickly bored with routines and structures that dont excite them. They typically require variety and diversity in their education and upbringing to maintain focus and attention.
Children with autism, however, do not respond well to unexpected changes and alterations to their schedules. Many children with ASD require intensely structured and established routines, and such a format might be the only way they feel comfortable in an academic or home setting.
Examples include consuming the same media or eating the same thing for dinner. A child with ADHD might become bored, distracted, or frustrated with a book or a TV show after just a few minutes or might want something else to eat after just a couple of bites.

Can You Have Adhd And Autism
Yes, itâs possible to have both conditions.
Itâs common for children with an autism spectrum disorder to also have signs of ADHD. Also, some kids whoâve been diagnosed with ADHD may also have a history of autism, with symptoms like trouble with social skills or being extra sensitive to textures of clothes.
One study found that children diagnosed with both conditions were more likely to have a combined type of ADHD, which includes hyperactive and impulsive symptoms plus trouble paying attention.
Some doctors have experience treating both conditions. If you canât find one who does, you may need to meet with more than one professional, like:
- Your childâs pediatrician
- A mental health specialist who treats ADHD and autism
Work with your childâs care team to find a treatment plan thatâs right for your little one. It might include both behavior therapy for autism and medication for ADHD.
Some doctors say that ADHD medication is important for children who have both conditions. ADHD drugs may help for certain autism symptoms that sometimes overlap with ADHD, like being hyper, impulsive, or inattentive. Stimulant ADHD medications may cause more side effects and might not work as well as they would for a child who has ADHD alone, though.

Autism In Women: Dispelling Myths
The medical establishment has been slow to develop an accurate profile of autism in women with low support needs.
Though our knowledge of autism, especially in women, is increasing, it has been slow to make its way into the mainstream. Its why common myths like the following persist, and why we must work to raise awareness:
1. Is ADHD on the autism spectrum? No. there is a clear distinction between the two. ADHD and autism are separate neurological differences that can both exist in the same person. Scientists have suggested that the two conditions have a biological connection, which causes a high rate of comorbidity.
2. Autistic people feel little or no empathy. This is categorically untrue. Some autistic people report feeling their emotions more intensely than most. This stereotype seems more connected to the social nuance used to convey emotion/empathy than to the actual experience of it.
3. You can immediately tell if someone is autistic. There is no way to know whether someone is autistic just by looking at or talking to them. Still, many people cant accept the fact that someone who isnt obviously disabled could be on the spectrum. In fact, I often hear people say to me, You dont look autistic!
Even though we have a long way to go toward neurodiversity empowerment, I encourage potentially autistic women to explore the possibility. As our ranks grow, perhaps the worlds understanding of us will grow as well.

Adhd & Asd: Differences
So intertwined is the relationship between ASD and ADHD that some have wondered if ADHD is itself an expression of autism. While it is clear that this is not the case, the close overlap between the two conditions, as well as public misunderstandings of their symptoms, gives rise to such misconceptions. ADHD and ASD are both neurodevelopmental disorders, the causes of which are not fully understood.
But for all the similarities between attention-deficit hyperactivity disorder and autism spectrum disorder, key differences make both conditions distinct.
For example, children who have ADHD typically struggle to pay attention to one subject and tend to get distracted quite easily. Children with autism may develop hyperfocus on one subject or object and will not focus on things of no interest.
An easy way to spot the difference between the two is when children do their homework. A child who has ADHD will likely not be able to concentrate on their assigned subject, even if it is a favorite. A child with autism will have an obsessive level of concentration on their favorite subject but will be unable to engage in subjects they are not interested in.
Conners Parent Rating Scale
As an analog to the dimensional CSBQASD score, we used the Conners Parents Rating Scale Revised-Long Version as a dimensional index of ADHD severity. Specifically, we used the combined raw score of the ratings on the DSM inattentive and DSM hyperactive/impulsive subscales as our measure of ADHD symptoms. In addition, we investigated the individual impact of the subscales by including their raw scores as separate regressors in supplementary analyses .

Adult Autism And Adhd
Though little research exists on autism and ADHD in adults, some studies estimate that the disorders coexist at rates between 20% and 37%.12
ADHD is characterized by symptoms of inattention, hyperactivity, and/or impulsivity different from the social communication symptoms and restricted behaviors associated with autism.
Still, some ADHD symptoms relate to the diagnostic criteria for autism. Not listening when spoken to directly, for example, is indicative of inattention, a common ADHD symptom. But given the strong social demands embedded in rating a person on this symptom, it could also indicate autism. If an adult is not making eye contact during a conversation, then it may give the appearance of not listening when spoken to directly. Differential psychiatric assessments as well as other diagnostic tools can help clinicians determine whether this symptom stems from distractibility or from deficits in social-emotional reciprocity and nonverbal communication .
Its critical for clinicians to consider whether an ADHD symptom appears in non-social situations. If a patient reports feeling distracted when working alone and without social demands, that may indicate ADHD more than autism. Distractions should be further analyzed is the patient daydreaming, or are they being pulled into a sound they hear that may be bothering them? The latter may indicate sensory sensitivity related to autism.
Getting The Proper Support
The first step in helping your child get the proper support is getting a correct diagnosis. You may need to seek out a child behavior disorder specialist.
A lot of pediatricians and general practitioners dont have the specialized training to understand the combination of symptoms. Pediatricians and general practitioners may also miss another underlying condition that complicates support plans.
Managing the symptoms of ADHD can help your child manage the symptoms of ASD, too. The behavioral techniques your child will learn may help lessen the symptoms of ASD. Thats why getting the proper diagnosis and adequate support is so vital.
Behavioral therapy can be helpful for ADHD, and is recommended as the first line of support for children under the age of 6. For children over the age of 6, behavioral therapy is recommended with medication.
Some medications commonly used to treat ADHD include:
- methylphenidate
- mixed amphetamine salts

Behavioural Analysis Of The Mid
Reaction times for both reward and non-reward conditions were transformed by a log10 transformation to conform to the equality of variance assumption. Trials with responses faster than 100 ms were excluded. RT for Reward and Non-Reward Hits were first compared across all participants in a paired t test using SPSS . Subsequently, linear mixed models were run in SPSS to model the effects of various factors on the RT for Reward Hits, Non-Reward Hits and the Reward HitNon-Reward Hit RT difference. Models included the relevant RT as its dependent variable and used dimensional scores of ASD and ADHD symptoms and their interaction, age, sex, IQ and scan site as fixed effects with Family ID modeled as a random effect. The ASD×ADHD interaction term was calculated as the element-wise multiplication of the centered ASD and ADHD variables. Medication use was added as an additional random effect in a separate model that included data from all participants for whom medication data was available. This model served as a sensitivity analysis to investigate the influence of medication usage.
Impact Of Comorbid Adhd And Asd
Diagnostic constraints have limited research on co-occurring ADHD and ASD, because many studies, in accordance with the DSM-IV, have excluded individuals with other psychiatric or developmental difficulties . There is preliminary evidence that when ADHD is comorbid with ASD, the risk for increased severity of psychosocial problems increases . Research comparing individuals with both diagnoses to individuals with a single diagnosis suggest that co-occurring symptoms are associated with greater impairment than a single diagnosis. By both parent and teacher reports children with ADHD and ASD experience more difficulty in daily life. Furthermore, these co-occurring conditions may be less responsive to standard treatments for either disorder. Children 48years old with ASD, whose parents report significant symptoms of ADHD, show lower cognitive functioning, more severe social impairment, and greater delays in adaptive functioning than children with ASD-only.

Make Time For Your Enjoyment
Both children and adults with ADHD or autism may benefit from having some downtime each day to do something they enjoy, such as reading, playing a musical instrument, or spending time with a pet. This can help to relieve stress and improve overall mood and focus. Also, when you choose to make time for yourself it directly impacts your ability to be more patient, present, and understanding with your loved ones who have ADHD or autism.
Summary And Future Directions
Research specifically focusing on co-occurring ADHD and ASD has only recently evolved, being previously limited by the DSM-IV exclusion criteria. What we have so far learned is that both disorders frequently co-occur, and when they do, they cause greater morbidity, and create a more complicated clinical challenge. The new DSM-V, allowing for a dual diagnosis, will hopefully facilitate research, by eliminating the exclusion of many patients and allowing the study of broader phenotypes. Most recent research focuses on etiology and clinical presentations, with less direct work on treatment and early intervention protocols. Very few studies have looked at pre-school children presenting with both conditions, on the impact of early intervention in this age group and its effect on developmental trajectory. Furthermore, many of the above quoted studies have used parent and/or teacher rating scales to assess clinical profiles, rather than direct clinical diagnoses of the two co-existing disorders. In the future, as a dual diagnosis is officially possible, studies using direct clinical assessment of both comorbid diagnoses are essential.

Possible Etiologies For The Co
Due to the previous DSM-IV diagnostic constraints, research concerning the possible etiologies of the co-occurrence of ADHD and ASD is scarce. The central focus of available research is in the fields of neuropsychology, genetics, and neuroimaging.
Although there are some important differences between the two disorders, as mentioned in the introduction, ASD and ADHD share many similar impairments in developmental and cognitive domains. Both are more common in males, have a strong comorbidity with intellectual disability, and are also associated with other specific learning and developmental difficulties, notably language, reading, and motor problems. Executive functions deficits are common in both disorders, together with response inhibition deficit. EF measures hardly discriminated between ADHD and HFA, but compared to children with ADHD, the HFA group showed more difficulty with cognitive flexibility and planning . Children with ADHD have pragmatic language difficulties similar to children in the ASD spectrum . Further neuropsychological similarities are suggested by a study of emotional recognition and theory of mind which showed that children with ADHD could not be distinguished from those with ASD .
When Adhd & Asd Occur Together
Although the two conditions are distinct, they often occur together, resulting in confusion and consternation. Almost 3 in 10 young children who have autism also show signs of ADHD, which is three times higher than for children in the general population.
Researchers published in the Autism journal noted that it isnt surprising that whatever might cause autism to develop in the brain could conceivably also cause a second developmental outcome, such as ADHD.
Past research has also theorized that autism and ADHD are two independent disorders that occur together through a third independent factor. What that factor might be is an ongoing question, but the most supported school of thought is that a genetic component is at play.
Several genetic studies have supported the theory that both ADHD and ASD have their origins in familial factors. The researchers who have examined this perspective suggest that shared genetic and neurobiological factors suggest why ADHD and ASD can occur with such frequency within the same family and the same patient.

Autism And Adhd: Overlaps And Differences
Kim attempted to open the door to her algebra class only to drop half of what was in her hands. Frustrated, she picked up her belongings, pushed her glasses back to her forehead, and tried again. School was a place where she could pour herself into her studies. She liked that, but she wished she didnt have to go from place to place making conversation with people and trying to make sure all her books were the correct match for whichever class she was attending.
Her autism made her day complicated enough, sometimes she wondered though, could there be something else at play? When she talked to her mom about it, her mom said, I wonder if you might have autism and ADHD.
At the same time? Kim inquired. Also, what is ADHD?
Her mom answered: Its attention deficit hyperactivity disorder.
They soon decided to call Kims doctor and find out if Kim did indeed have both conditions.
Like Kim and her mom, you may be wondering if someone can have autism and attention deficit hyperactivity disorder together. Lets explore this topic.
How Does Treatment For Adhd And Autism Differ
Treatments for both ADHD and autism can vary depending on the severity of the condition and how much the symptoms affect everyday life.
Behaviour therapy and medication can help with both these conditions. With autism, however, extra therapy may be recommended such as counselling, education support, speech therapy and occupational therapy.
With both, an early diagnosis can help children and their families to manage the condition. If you are at all concerned that your child has either ADHD or autism, its a good idea to speak to your doctor or paediatrician as soon as possible.

Fmri Analysis Of Reward Anticipation
All fMRI analyses were controlled for effects of age, sex, IQ, scan site and ODD/CD comorbidity. Reward anticipation was associated with significant activation in a network of brain areas including the ventral striatum, amygdala, insula, cingulate cortex and visual areas . Non-reward anticipation was related to stronger activity in the posterior cingulate and bilateral inferior parietal cortex.

How Adhd And Autism Are Related
As we are now aware of these two disorders, it is important to understand how they are related. Both ADHD and autism share some common symptoms and differences too. It is believed that both these disorders have a genetic basis. So, if you have a family member with autism, you are at an increased risk of developing ADHD.
Both these disorders can cause problems in your overall quality of life. Lets further deal with the similarities and differences between ADHD and autism.

Is Adhd A Form Of Autism
Although attention deficit hyperactivity disorder is not a form of autism spectrum disorder , the two conditions are related in several ways. Many symptoms of ASD and ADHD overlap, making correct diagnosis challenging at times. They are linked in various ways, but it is important to understand that ADHD is not ASD.
Having one of the illnesses may increase your risk of getting the other. Both ASD and ADHD tend to run in families and are specified by the Diagnostic and Statistical Manual of Mental Disorders , a handbook used by healthcare professionals in the United States for the diagnosis of mental disorders. A comparison of ADHD and ASD is given below.
Definition as per DSM
Autism Spectrum Disorder :
- A neurodevelopmental disorder that causes social communication difficulties, repetitive behaviors, and restricted interests. Consistent symptoms must appear before three years of age.
- A neurodevelopmental condition characterized by inattention, hyperactivity, and impulsivity.
