Angelman Syndrome (AS) is a genetic disorder that affects the nervous system and can cause developmental disabilities. It is caused by a deletion of genetic material on the 15th chromosome. Symptoms of Angelman Syndrome include severe intellectual disability, absence of speech, ataxia (loss of muscle coordination), and frequent laughter and smiling.
Speech Development in Angelman Syndrome
Most people with Angelman Syndrome are nonverbal due to the severe intellectual disability and lack of speech development. Research indicates that only about 10 percent of individuals with AS can develop enough speech to communicate basic needs. For those who do, it may take longer to learn to speak than usual.
Causes of Nonverbalism in Angelman Syndrome
There are several factors that can contribute to nonverbalism in individuals with Angelman Syndrome. These include the following:
• Developmental delays: Many individuals with AS experience delays in development, which can affect their ability to learn language and speech.
• Cognitive dysfunction: Angelman Syndrome is associated with cognitive dysfunction, which can further impede language and speech development.
• Motor impairment: Individuals with AS may experience motor impairments, such as difficulty with fine and gross motor coordination, which can also contribute to nonverbalism.
Treatment for Nonverbalism in Angelman Syndrome
Although there is no cure for Angelman Syndrome, there are treatments available to help individuals with AS communicate. Speech therapy can help individuals learn to use alternative forms of communication, such as sign language, picture cards, and other methods of augmentative and alternative communication (AAC).
In addition, there are several technologies and tools that can help individuals with AS communicate, such as speech-generating devices (SGDs), and text-to-speech software. It is important to remember that each individual with AS is different, and it may take some trial and error to find the right method of communication for them.
Conclusion
Individuals with Angelman Syndrome are often nonverbal due to the severe intellectual disability and lack of speech development associated with the disorder. However, there are treatments available to help individuals with AS communicate, such as speech therapy, augmentative and alternative communication (AAC) methods, and various technologies and tools. Each individual is different, so it may take some time to find the right method of communication for them.
