Developmental Verbal Dyspraxia (DVD), also known as Childhood Apraxia of Speech (CAS), is a speech disorder that affects a person’s ability to coordinate the movements needed for speech. This condition can make it challenging for individuals, especially children, to communicate effectively. In this article, we will explore what DVD is, its types, common causes, symptoms, diagnostic tests, available treatments, and medications, as well as surgical options when necessary.
Developmental Verbal Dyspraxia, or DVD for short, is a speech disorder that affects the ability to plan and execute the movements needed for speech. It primarily impacts children, making it difficult for them to speak clearly and form words properly. This condition can be frustrating for both children and their parents, as it can hinder effective communication.
Types of Developmental Verbal Dyspraxia:
There are various types of DVD, including:
- Childhood Apraxia of Speech (CAS): This is the most common type of DVD and usually affects children from a young age.
- Acquired Apraxia of Speech: This type of DVD occurs as a result of brain damage due to injury, stroke, or other medical conditions.
Common Causes of Developmental Verbal Dyspraxia:
The exact cause of DVD is not always clear, but there are several factors that can contribute to its development. These include:
- Genetic Factors: Some children may inherit a predisposition for DVD from their parents.
- Neurological Conditions: Brain abnormalities or damage can lead to DVD.
- Premature Birth: Babies born prematurely may have a higher risk of developing DVD.
- Muscle Weakness: Weak muscles in the mouth and tongue can make it difficult to coordinate speech movements.
- Neurodevelopmental Disorders: Conditions like autism or Down syndrome can be associated with DVD.
- Environmental Factors: Exposure to toxins or infections during pregnancy may increase the risk.
- Hearing Impairments: Difficulty hearing can impact a child’s ability to learn and develop speech.
- Traumatic Brain Injury: Head injuries can damage the brain’s speech centers, leading to DVD.
- Low Birth Weight: Babies with low birth weight may be more susceptible to DVD.
- Inadequate Speech Exposure: Limited exposure to language in early childhood can contribute to DVD.
- Family History: A family history of speech disorders may increase the risk.
- Neuromuscular Disorders: Conditions affecting muscle control can lead to DVD.
- Metabolic Disorders: Some metabolic conditions can impact speech development.
- Brain Tumors: Tumors in the brain can disrupt speech-related brain areas.
- Cleft Palate: Structural abnormalities in the mouth can affect speech.
- Infections: Certain infections during pregnancy or early childhood may play a role.
- Sensory Processing Issues: Difficulty processing sensory information can affect speech development.
- Nutritional Deficiencies: Lack of essential nutrients can impact overall development, including speech.
- Lack of Stimulation: Insufficient speech stimulation in the child’s environment can hinder development.
- Environmental Toxins: Exposure to environmental toxins may contribute to DVD.
Common Symptoms of Developmental Verbal Dyspraxia:
Identifying the symptoms of DVD can help in early diagnosis and intervention. Common symptoms include:
- Difficulty Pronouncing Words: Children with DVD may struggle to form and pronounce words correctly.
- Limited Vocabulary: They often have a smaller vocabulary than their peers.
- Inconsistent Speech Errors: DVD can lead to inconsistent errors in speech sounds.
- Difficulty with Longer Words: Longer words can be especially challenging to pronounce.
- Difficulty with Sequences: Children with DVD may have trouble saying sequences of sounds or syllables.
- Frequent Pauses: They may pause frequently when speaking.
- Difficulty with Intonation: DVD can affect the natural rise and fall of speech.
- Repetition of Sounds: Repeating sounds or syllables is common.
- Frustration with Communication: Children may become frustrated when others have difficulty understanding them.
- Groping Movements: They may make repeated attempts to produce a sound, using groping movements of the tongue and lips.
- Difficulty with Speech Therapy: DVD can make speech therapy progress slower and more challenging.
- Struggles with Nonverbal Communication: Some children with DVD may also have difficulty with nonverbal communication, like gestures and facial expressions.
- Limited Expressive Language: Their ability to express themselves through language may be limited.
- Speech Sound Omissions: They may leave out certain speech sounds when speaking.
- Difficulty with Reading and Writing: DVD can impact literacy skills.
- Social Challenges: Communication difficulties can lead to social challenges and isolation.
- Frustration and Low Self-esteem: Children with DVD may experience frustration and low self-esteem due to their speech difficulties.
- Difficulty Following Directions: Understanding and following spoken directions can be challenging.
- Misarticulation of Sounds: DVD can lead to the misarticulation of sounds in words.
- Persistent Speech Issues: Symptoms of DVD may persist over time if not addressed.
Common Diagnostic Tests for Developmental Verbal Dyspraxia:
Diagnosing DVD typically involves a comprehensive evaluation by a speech-language pathologist (SLP). Here are some common diagnostic tests and assessments:
- Oral Motor Assessment: Evaluates the coordination and strength of oral muscles involved in speech.
- Speech Sound Assessment: Assesses the ability to produce specific speech sounds.
- Phonological Assessment: Analyzes the patterns of speech sound errors.

- Anti-seizure Medications: In cases where seizures co-occur with DVD.
- Beta-Blockers: May help with physical symptoms of anxiety.
- Sleep Medications: If sleep disturbances are an issue.
- Non-Stimulant ADHD Medications: An alternative to stimulant medications for managing attention difficulties.
- Antihistamines: Occasionally used for sedative effects.
- Melatonin: For sleep regulation.

Surgical Options for Developmental Verbal Dyspraxia:
Surgery is not a primary treatment for DVD, but it may be considered in specific cases where structural abnormalities contribute to the condition. Here are 10 surgical options that could be explored:
- Frenectomy: If a tight lingual frenulum (the tissue connecting the tongue to the floor of the mouth) restricts tongue movement, it can be surgically released to improve speech.
- Cleft Palate Repair: For individuals with a cleft palate, surgical repair may be necessary to improve speech and overall oral function.
- Tonsillectomy and Adenoidectomy: Enlarged tonsils or adenoids can obstruct the airway, leading to speech difficulties. Surgery to remove them can help.
- Pharyngeal Flap Surgery: In cases of severe velopharyngeal dysfunction (difficulty closing the opening between the nose and mouth during speech), a pharyngeal flap may be created surgically.
- Laryngeal Surgery: If vocal cord issues contribute to speech difficulties, surgical procedures may be considered.
- Cochlear Implants: In individuals with both DVD and hearing impairment, cochlear implants can improve communication.
- Tongue Reduction Surgery: In cases of macroglossia (an unusually large tongue), surgery may be performed to reduce tongue size.
- Nasal Surgery: To address nasal obstructions that affect speech.
- Throat Surgery: Surgical interventions for conditions that affect the throat and vocal cords.
- Gastrostomy Tube Insertion: In severe cases of DVD where oral feeding is not possible, a gastrostomy tube may be surgically inserted for nutrition.
Surgical options are typically considered after a thorough evaluation by a medical team and when non-surgical treatments have been ineffective or when there are structural issues that require correction.
