There is a new study out that reinforces my observations that dementia, Alzheimer's Dementia in particular, involves more than just memory loss. In this study, researchers found that speech problems are early markers of AD. These problems worsen with progression of the disease and are labeled as Primary Progressive Aphasia (PPA), "aphasia" being a medical term for the loss of verbal expression.
Word Finding or Word Searching means the inability to immediately speak the correct word. We say "it's on the tip of my tongue" and while it happens to all of us at times, it is more common in people with neurological disorders like AD. Other verbal signs of PPA include a decrease in fluency and gramaticality, repetition, and difficulty naming things.
If someone you love starts developing these symptoms, try to get professional help. It is difficult because the person with early Alzheimer's will be the last one to recognize and acknowledge the problem. In fact, you may find yourself in a defensive position which, believe me, is not fun. The rest of this post is from an earlier one on the same subject.
