Apraxia of speech and dyslexia are two different disorders that can impact a person’s ability to communicate effectively. Apraxia of speech involves difficulty with planning and coordinating the muscle movements necessary for speech, while dyslexia affects a person’s ability to read, write, and spell. While these two disorders may seem unrelated, recent research suggests that they may be more connected than previously thought.
Understanding the connection between apraxia of speech and dyslexia can help improve assessment and treatment strategies for individuals with these disorders. This article will explore the similarities and differences between apraxia of speech and dyslexia, as well as the latest research on their connection.
What is Apraxia of Speech?
Apraxia of speech is a neurological disorder that affects a person’s ability to plan and coordinate the muscle movements necessary for speech. It is also known as verbal apraxia or dyspraxia. Individuals with apraxia of speech may know what they want to say, but have difficulty producing the correct sounds, words, and sentences.

Symptoms of Apraxia of Speech
- Inconsistent errors in speech
- Difficulty initiating speech
- Difficulty imitating speech sounds
- Difficulty with intonation and rhythm of speech
- Simplification of words or using alternative words to communicate the intended meaning
- Struggles with repeating longer phrases or sentences
Causes and Risk Factors
- Neurological damage or injury to the parts of the brain responsible for speech planning and production
- Stroke, traumatic brain injury, or degenerative diseases like Parkinson’s or ALS
- Genetics or family history of apraxia of speech
Diagnosis
- A comprehensive assessment by a speech-language pathologist
- Examining the patient’s speech and language abilities
- Assessing the patient’s ability to perform oral-motor movements
- Conducting an imaging test like an MRI or CT scan to identify any neurological damage

Treatment
- Treatment for apraxia of speech may include a combination of different techniques.
- Speech therapy focused on improving articulation, motor planning, and coordination.
- The use of visual and auditory cues to facilitate speech production.
- Practice exercises to improve speech sound production and sequencing.
Some patients may also benefit from alternative communication methods like sign language or assistive technology devices.
What is Dyslexia?
Dyslexia is a learning disorder that affects a person’s ability to read, write, and spell. Individuals with dyslexia may have difficulty decoding words, recognizing sight words, and comprehending written text.
Symptoms of Dyslexia
- Difficulty decoding words and recognizing sight words
- Slow reading speed and accuracy
- Difficulty comprehending written text
- Difficulty with spelling and writing
- Struggles with phonological awareness and phonemic awareness
- Difficulty with verbal memory and recall
Causes and Risk Factors
- Genetics or family history of dyslexia
- Neurological differences in the brain’s language processing areas
- Environmental factors such as premature birth, low birth weight, or exposure to toxins during pregnancy
Diagnosis
- A comprehensive evaluation by a psychologist or educational specialist
- Assessment of reading, writing, and spelling abilities
- Examination of cognitive and language processing skills
- Observation of classroom behavior and academic performance
Treatment
- Evidence-based interventions for dyslexia may include a combination of different techniques.
- Phonics instruction to improve decoding and word recognition
- Reading fluency training to improve reading speed and accuracy
- Comprehension strategies to improve reading comprehension
- Writing instruction to improve spelling and writing skills
- Use of assistive technology such as text-to-speech software or audiobooks
The connection between Apraxia of Speech and Dyslexia
Recent research has suggested a possible connection between apraxia of speech and dyslexia. While these two disorders affect different areas of communication, they share some similar characteristics and may impact each other’s development.
Shared Characteristics
- Both disorders involve difficulty with phonological processing, which is the ability to recognize and manipulate sounds in language.
- Both disorders may be linked to differences in the brain’s language processing areas.
Overlap in Diagnosis
- Dyslexia and apraxia of speech can sometimes co-occur in individuals.
- Some individuals with dyslexia may also have difficulty with speech production and motor planning, which are characteristic symptoms of apraxia of speech.
- Some individuals with apraxia of speech may also have difficulty with phonological awareness and decoding, which are characteristic symptoms of dyslexia.
Overlap in Treatment
- Interventions for dyslexia may also benefit individuals with apraxia of speech, as they focus on improving phonological processing and decoding skills.
- Speech therapy techniques for apraxia of speech may also be helpful for individuals with dyslexia who struggle with speech production and motor planning.
Strategies for Supporting Individuals with Apraxia of Speech and Dyslexia
Individuals with apraxia of speech and dyslexia may benefit from a variety of strategies and interventions to support their communication and learning needs. Here are some strategies that may be helpful:
Early Intervention
Early identification and intervention for both apraxias of speech and dyslexia are crucial. The earlier these disorders are detected and treated, the better the outcomes are likely to be.Â
Parents, teachers, and caregivers should be aware of the signs and symptoms of these disorders and seek professional help as soon as possible.
Multidisciplinary Approach
A multidisciplinary team approach involving speech-language pathologists, educators, psychologists, and other professionals may be necessary to fully support individuals with apraxia of speech and dyslexia.
This team can work together to develop individualized education plans (IEPs) or treatment plans that address the specific needs of each individual.
Assistive Technology
Assistive technology can be a helpful tool for individuals with apraxia of speech and dyslexia.
Speech-to-text software, text-to-speech software, and audiobooks can help with reading, writing, and communication. Electronic communication devices can also be used to assist with speech production.
Direct Instruction
Direct instruction in phonological processing, decoding, and spelling can be beneficial for individuals with dyslexia. For individuals with apraxia of speech, direct instruction in speech production and motor planning can be helpful. A speech-language pathologist can provide this type of instruction.
Accommodations and Modifications
Individuals with apraxia of speech and dyslexia may require accommodations and modifications to access the curriculum and communicate effectively.
Examples of accommodations may include extended time on tests, preferential seating, or access to audiobooks. Modifications may include simplified language or alternative assignments.
Social-Emotional Support
Individuals with apraxia of speech and dyslexia may experience frustration, anxiety, and low self-esteem related to their communication and learning difficulties.
Social-emotional support from parents, teachers, and other professionals can be helpful in building confidence and improving well-being.
Conclusion
Apraxia of speech and dyslexia are two different communication disorders, but they share some common characteristics and may impact each other’s development.
Both disorders involve difficulty with phonological processing and may be linked to differences in the brain’s language processing areas.
While more research is needed to fully understand the connection between these two disorders, a multidisciplinary approach to assessment and treatment can help improve outcomes for individuals with either or both disorders.
Strategies such as early intervention, assistive technology, direct instruction, accommodations and modifications, and social-emotional support can all be helpful in supporting individuals with apraxia of speech and dyslexia.
