Angelman syndrome or “puppet syndrome” is a rare genetic disorder causing developmental disabilities and nerve-related symptoms. It usually isn’t detected until developmental delays become noticeable, usually around six to twelve months of age. Symptoms include lack of crawling or babbling, minimal speech, and frequent smiling and laughter. Inability to walk, move, or balance well (ataxia) is also a symptom.
Communication is greatly affected by the syndrome. Most children with Angelman syndrome have limited speech, up to four words, or no speech. Their comprehension/receptive skills are usually stronger than their expressive ones. Majority of those with Angelman syndrome express their needs by sign language, gestures, or picture communication. Speech therapy, along with occupational and physical, focuses on improving their communication, gross, and fine motor skills.
