Understanding your child with non or very limited verbal communication: 

The implications of communication barriers in having HD + DS means your child will have a difficult time communicating to you what hurts and how much it hurts. 

Children with Down syndrome often face significant challenges in developing language and communication skills, which can impact their ability to understand, respond to, and produce spoken language. Here are some key points regarding these challenges and their underlying causes:

Communication Challenges

1. Understanding Spoken Language

   • Difficulty in processing verbal information.

   • Challenges in auditory discrimination and auditory processing.

2. Responding to Spoken Language

   • Delayed response time.

   • Difficulties in organizing and sequencing thoughts.

3. Producing and Using Speech

   • Speech may be slurred or imprecise due to low muscle tone.

   • Difficulty in forming words clearly.

4. Sequencing Thoughts and Ideas

   • Challenges in organizing ideas in a logical order.

   • Trouble with constructing coherent sentences.

5. Putting Words into Sentences

   • Struggles with syntax and grammar.

   • May use telegraphic speech (omitting non-essential words).

Possible Reasons for Communication Challenges

1. Anatomical Differences

   • Low Muscle Tone: Hypotonia in the tongue, lips, and jaw can lead to unclear speech.

   • Larynx Size and Shape: Smaller larynx and incomplete development of sinus structures affect voice quality.

   • Open Mouth Posture: Often leads to mucosal issues and a need for higher fluid intake.

2. Verbal Short-Term Memory Difficulties

   • Problems with retaining and processing spoken information.

   • Difficulty in following multi-step instructions.

3. Hearing Loss

   • Common in children with Down syndrome, affecting both expressive and receptive language skills.

4. Auditory Processing Issues

   • Deficits in distinguishing and interpreting sounds.

5. Hypotonia

   • Reduced muscle tone contributes to a gruff or low-pitched tone of voice.

Strategies to Aid Communication

1. Early Intervention Therapies

   • Speech Therapy: To improve articulation and clarity of speech.

   • Occupational Therapy: To enhance fine motor skills and oral motor control.

2. Alternative and Augmentative Communication (AAC)

   • Sign Language: Helps bridge the gap while verbal skills develop.

   • AAC Devices: Electronic devices that assist in communication.

   • Picture Exchange Communication System (PECS): Uses pictures to communicate needs and desires.

   • Spellers Method: Emerging research suggests it may be beneficial, though more evidence is needed.

3. Whole Word Reading

   • Encourages recognition of whole words to support language comprehension and production.

4. Parental Intuition and Support

   • Parents play a crucial role in interpreting and understanding their child's needs and finding effective communication strategies.

Additional Insights

• Energy Expenditure for Voice Initiation

  • People with Down syndrome require nearly twice the energy (131.57 microvolts) compared to the average person (72.52 microvolts) to initiate vocal cord vibrations necessary for speech【https://cdn.dseonline.app/pubs/a/reports-39.pdf】.

Conclusion

Understanding the specific challenges faced by children with Down syndrome in language and communication development is crucial. Tailored interventions, early support, and the use of alternative communication methods can significantly aid in improving their ability to communicate effectively.
