Augmentative and Alternative Communication, sometimes referred to as AAC is a method of communication used by individuals with a wide range of speech and language impairments, including congenital impairments such as cerebral palsy, intellectual impairment and autism, and acquired conditions such as amyotrophic lateral sclerosis (ALS) and Parkinson's disease.
AAC is for those individuals who are unable to use verbal speech, yet are cognitively able, or individuals whose speech is extremely difficult to understand. AAC can be a permanent addition to a person's communication or a temporary aid.
The evaluation of a user's abilities and requirements for AAC will include the individual's motor, visual, cognitive, language and communication strengths and weaknesses. The evaluation should include the input of family members, particularly for early intervention. You should also enlist the expert help of a Speech language pathologist, occupational therapist, or other AT professional to help with the decision. Here is a list of specific questions to consider.
