What Is The Cause Of Dyspraxia
Whilst the exact cause of dyspraxia is unknown, research suggests that it is more than likely a result of a delayed or impaired development of neurones in the brain, rather than brain damage.
Dyspraxia is not hereditary, but members of the same family sometimes display similar dyspraxic symptoms.
Can you have dyslexia and dyspraxia?
Learning difficulties which affect the way information is processed are known as Specific Learning Difficulties and include:
Dyspraxia Attention Deficit Disorder Attention Deficit Hyperactivity Disorder
It is fairly common for someone with dyspraxia to also have other learning difficulties such as dyslexia and ADD . These are known as co-occurring difficulties and symptoms can vary in severity from person to person.
Can Dyslexia Be Like Autism
Can dyslexia have the same behavioural issues as autism? Ive been told I have had dyslexia for a while but people have said i should get checked for autism. Can it seem the same? Have a good day

Horse shoe theory.
Basically we can have very similar traits, but the reasons for them can come from opposite ends of a reasoning.
For instance autistics often become obsessed by smaller detail. Dyslexics often seek the broadest understanding of a given subject. But to the outside observed they just see an obsession with a subject.
Also misdiagnosis is rift you can go to 5 different people each will tell you have completely different things. When i was 5 my teacher thought i was deaf. At 8 diagnosed with dyslexia. By one of the best specialists apparently then only recently at 23 diagnosed with high functioning Aspergers. The overlap happens allot consider doing youre own research in my subjective experience experts are clueless always get stuff wrong but that is my experience do what you think is best.
Could Dyslexia Be A Comorbidity Of An Autism Spectrum Disorder
Both autism spectrum disorders and dyslexia can be classified as neurodevelopmental conditions with rising prevalence amongst children. Officially an autism spectrum disorder is an exclusionary criterion for a diagnosis of dyslexia and vice versa .
There are, however, significant symptoms that are shared by these two conditions and which inform the opinion that, although autism and dyslexia are distinct conditions, they can occur in the same individual. Research concerning the connection between ASD and dyslexia is scant, but studies have explored a gene shared between the two neurodevelopmental conditions.

Do Dyslexics Confuse Left And Right
In left-right confusion, a person has trouble distinguishing right from left. Individuals with this disorder may have trouble with directions or reading maps. This is sometimes called directional dyslexia, but thats inaccurate. As with dyscalculia, it may appear with dyslexia, but its not a form of dyslexia.
What Is Pathological Demand Avoidance
Pathological Demand Avoidance or PDA is a new proposed subset of Autism, which is not in the official diagnostic manuals. As a result, some have labelled it as a distinct condition in the same way Aspergers was once used. Pathological Demand Avoidance is also often used as a term to describe how an individual will experience an overwhelming need to avoid or resist demands .
It is really important to understand that when a child is avoiding demands, it is because of anxiety, even if it doesnt look like anxiety. This is very important to keep in mind, because parents can often respond with more demands which then increases the anxiety further. Sometimes autistic children will avoid demands with challenging behaviours, but the underlying cause is still anxiety. This means that the most important thing to do is to search for the cause of the anxiety and support that. Your child might be screaming or kicking or biting and running away but it is important to remember that although this might not look like typical anxiety this is something that is causing your child distress and anxiety and something they need to be supported with.

How Do The Symptoms Of Asd And Ld Overlap
ASD and learning disabilities share some common characteristics:
- Both are lifelong conditions
- Both can significantly impact a persons life
- Early detection and intervention is important in both
- Sensory processing issues, emotional dysregulation , and trouble with social skills are common in ASD and all learning disabilities
These and other overlapping symptoms can make both ASD and LDs difficult to diagnose:
- ASD, social communication disorder, ADHD, and receptive language learning disabilities may all include trouble reading non-verbal cues, including determining other peoples feelings based on facial expressions. A person with any one of these conditions may be a literal thinker who often does not understand puns, riddles, sarcasm, and figures of speech.
- ASD and ADHD both share difficulties with executive function, including organization, time management, problem solving, and emotional dysregulation.
- ASD, ADHD, and sensory processing disorders all include sensory issues. People with sensory issues may either seek out or avoid sensory input.
- ASD, dyspraxia, dysgraphia, and sensory processing disorders can all cause motor skill problems, clumsiness, and poor handwriting.
- ASD, language-based learning disabilities, and nonverbal learning disabilities can all make it difficult to verbally express yourself, follow conversations, and speak at an appropriate volume and/or inflection.
Attention Deficit Hyperactivity Disorder
Symptoms of ADHD include:
- finding it hard to concentrate and getting distracted easily
- acting without thinking
- finding it hard to sit still
People with ADHD may need extra support at school or work. Sometimes they need to take medicine.
- problems with reading, writing and spelling
- clumsy movements and problems with organisation and following instructions
Extra support at school can often help.

Trauma Dyslexia Also Referred To As Acquired Dyslexia
When an adult or child has a brain injury from trauma or disease, they can sometimes develop difficulties with language processing, which result in dyslexia.
If you are looking into the research, you’ll find references to many other so-called ‘types’ too. The term Perceptual Dyslexia, is associated with people who have trouble recognizing whole words, which causes slow reading. Linguistic Dyslexia is sometimes brought up when individuals read quickly but still make mistakes and struggle with comprehension. There are some people who discuss Auditory, Spatial or even Math Dyslexia. For this last one, it is hard to pinpoint where a ‘Math Dyslexia’ type and dyscalculia would differ.

Reading Spelling And Handwriting Difficulties
As mentioned before, the challenges of dyslexia become more apparent as children learn to read and write. As reading and writing depend on similar underlying processes, children with dyslexia often have writing difficulties .
Handwriting challenges may apply to autistic children too. According to Fuentes et al. children with ASD showed a worse performance on handwriting tasks in comparison to age and intelligence matched children in the control group.
As far as reading deficits are concerned, an overview of neuroimaging studies titled Reading, dyslexia and the brain reveal that a convergence of studies show the dyslexic brain is characterized by under-activation of the vital neural networks for reading.
This biological basis of dyslexia disproves the hurtful sentiment that dyslexic children should just try harder. Once teachers and peers realize that, for dyslexic children, learning and reading difficulties may stem from deficits in processing the sound system of language, such myths will hopefully be dispelled.
With regards to reading in children with autism, the spectrum nature of the condition once again means some autistic individuals excel at reading while others face severe reading impairments. Reading impairments in autistic children are especially prevalent when it comes to comprehension. Autistic children may figure out how to decode words and appear to read well but comprehension of what they are reading may be negatively affected.
Is Dyslexia A Form Of Autism
Autism and dyslexia link which each other in the way the brain processes information. This is the reason it is not uncommon for people on the spectrum to consider the diagnosis of dyslexia.
People suffering from dyslexia face difficulties in reading, writing, and spelling moreover in interpreting maps, graphs, sequences, and patterns.
While the people on the spectrum, have additional frustration of being unable to read or write can lead to feelings of even greater isolation and frustration. Sometimes they can be angry and uncooperative without any reason.
People having dyslexia and autism should undergo the best treatment to overcome both issues.

Arg853 Is A Unique Site Of Dock4 Among All Dock Families And Is Highly Conserved During Evolution
Arg853 of human Dock4 is located in the linker region between DHR1 and DHR2 domains , a region that has no known molecular function yet. We searched the UniProtKB Protein knowledgebase1 and compared the sequence of amino acid sequences of Dock4 among different species, including frog , mouse , rat , marmoset , rhesus macaque , chimpanzee , and human . By using the Multiple Sequence Alignment analysis tool of Clustal Omega2, we found that the Arg853 and its flanking sequences are highly conserved during evolution . However, this region is not conserved in other Dock family members , suggesting that this region is unique in Dock4.
Orthographic Dyslexia: Its Not Just About Phonology
by Sarah C. Wayland, Ph.D. | Mar 5, 2019 | Special Needs Care Navigation, Therapy |
I recently had a conversation with my colleague, Donna Henderson, Psy.D., about a form of dyslexia that she has noticed in some of her clients with autism. My curiosity was piqued because I had noted similar patterns of spelling errors in a number of my clients, but couldnt find a description of the phenomenon in books and articles describing more common forms of developmental dyslexia. When I asked Dr. Henderson for details, she sent the following essay, which she has graciously agreed to allow me to post. Sarah Wayland
Poor awareness of the sounds of language or a lack of understanding of the spelling-sound correspondence is the cause of the most common type of dyslexia. People with this type of dyslexia will make spelling errors that do not make phonetic sense . In contrast, I have noticed that some of the children I work with have an unusual pattern of spelling errors. These kids seem to understand which letters go with which sounds, but they actually over-rely on the letter-sound correlation. For example, they might spell the word garbage as garbij or the word wiggle as wigul.
To understand these different types of errors, its important to first understand how children learn to read as well as what typical dyslexia looks like. It all starts with the phoneme.
Beginning readers and writers must use the phonological form of the word to determine how say or spell it.

Learning Solutions For Dyslexia
Approaches may vary depending on the symptoms, but most individuals with dyslexia respond well to technology that breaks learning down into bite-size units. It allows them to proceed through a course at their own pace, learning one step at a time and repeating modules until they are ready to move on.
Overlearning is another hepful strategy that can also benefit children with attention deficit disorder/ attention hyperactive disorder and other specific learning difficulties.
Similarities Between Autism & Dyslexia
Dyslexia and autism both tie into how the brain processes information, so it fairly common for people with autism to also be diagnosed with dyslexia.
Although there may be some co-occurrence of autism and dyslexia, these are different disorders and they are not closely linked. Autism is a developmental disorder, while dyslexia is a learning disability, which is a term encompassing various struggles with the learning process.
Overlap between learning disabilities like dyslexia and developmental conditions like autism include the following:
- Neither has a cure, though both have treatment options.
- Both are lifelong conditions.
- Both impact the individuals life and make some parts of functioning in society more difficult.
- Early detection and management are important for both.
Emotional and behavioral issues appear in both, including:
- Emotional dysregulation.
- Sensory processing issues.
- Trouble with social skills.
Neurotypical children begin learning about phonemes and the basics of reading while they are in preschool, starting around 4 years old. Early elementary school is when the reading process truly begins, so many children are found to be dyslexic around 6 years old. This means they can have access to special reading programs and learn ways to process textbooks, like audiobooks or reading with special fonts.
Children with autism are no more likely to have dyslexia than their neurotypical peers, but it may be harder to detect dyslexia in children on the autism spectrum.

Teaching Solutions For Dyslexia
Teachers can help dyslexic students in the classroom by being aware of learning difficulties and providing extra time for students to process and learn new material. For example, children can benefit greatly by learning how to read sight words.
These are service words and prepositions that are commonly found in classroom reading materials. Nonetheless, they can be difficult words for dyslexic children to remember as they are less amenable to mnemonic devices. Teaching sight words through extensive repetition via a spelling program is often the best solution.
Allowing students to type assignments when possible is another good strategy. It can help reduce the time a dyslexic child needs to complete assignments by removing the mechanics of writing from the task, and giving them access to spell checkers.
You may also try to teach specific strategies for spelling. Above all, provide plenty of praise. Developing literacy skills is a challenge and your students will need the encouragement. Learn more about teaching students with dyslexia.
What Are The Symptoms Of Autism Spectrum Disorder
ASD is a neurodevelopmental disorder that affects how people process certain types of information. The main symptoms are:
- difficulty with social interactions
- engaging in repetitive or ritualistic behaviors
- obsessions with certain topics of interest
Individuals with ASD may share some symptoms in common, such as difficulty in social interactions and repetitive behaviors. But because it is a spectrum disorder, these symptoms can range from mild to severe. Everyone experiences ASD differently. Some children with autism have speech or intellectual delays some do not. Some may have average or above-average IQs. Some may be high-functioning and others may have a severe disability.

Evidence Of Symptom Overlap Asd And Adhd
Various studies have looked for ADHD or ADHD symptoms in samples of children with autism or ASD. Rates of ADHD have ranged from 28% to 78% of these samples . Studies that look at ADHD symptoms have reported even higher numbers: for example, Sturm, Fernell, & Gillberg, looked at a sample of around 100 high functioning children with ASD and found 95% had attention problems, 75% had motor difficulties, 86% had problems with regulation of activity level, and 50% had impulsiveness. About three-quarters had symptoms compatible with mild or severe ADHD, or had deficits in attention, motor control, and perception, indicating a considerable overlap between these disorders and high-functioning ASD in children.
In an large analysis of nine hundred forty-six twins, Reierson and colleagues assigned DSM-IV ADHD diagnoses, and measured autistic traits using the Social Responsiveness Scale. The study showed that there are clinically significant elevations of autistic traits in children meeting diagnostic criteria for ADHD. These findings confirm results in earlier studies . Santosh and Mijoovic which found children with ADHD had elevated levels of impairment in all three autistic symptom domains, namely social deficits, communication and stereotyped behaviors. Clark et al found 65-80% of parents of children with ADHD reported difficulties in social interaction and in communication . So the presence of autistic traits in children with ADHD appears common .
