In spite of language losses suffered by an individual with Alzheimer’s, many skills that support communication are remarkably preserved and remain for a long time. When working with the AD individual, the caregiver should keep in mind six abilities that are nearly always preserved.
1) The Use of Procedural Memories
Individuals with AD begin to lose memory for words, information and events quite rapidly, but procedural memory, or the knowledge of how to perform familiar tasks remain relatively intact until the later stages of dementia. The research suggests that this is because procedural memory is the most elemental of human memory systems and is the only memory system capable of operating independently. This system can sustain some very complex human activity such as walking, washing hands, or even driving a car. Procedural memory is like a computer program whereas other types of memory are like data stored in the computer. Alzheimer patients begin to lose data rapidly but still function. They may forget where they are going, but they still know how to walk. They may forget what they are saying, but they still know how to talk.
