Alzheimer disease is a form of dementia that slowly reduces a person's mental faculties to the point, where in the later stages, the person can no longer function physically. It is a progressive disease with no cure; however, there are new drugs on the market that can slow its progress, and there are some promising tests which may diagnose it in the early stages to allow for earlier treatment. Alzheimer's is the most common progressive dementia. We all, at times, feel or sometimes even say “I think I’m getting Alzheimer’s.”
We relate the disease to forgetting where we put the keys, or “that senior moment.” Really it’s not about forgetting where you put your keys it more about forgetting what your keys are for.
For the first time in 27 years, clinical diagnostic criteria for Alzheimer’s disease dementia have been revised, and research guidelines for earlier stages of the disease have been characterized to reflect a deeper understanding of the disorder.
The guidelines released April of 2011 cover the disease from pre-Alzheimer’s and across its many gradually changes over many years.
The original criteria were the first to address the disease and described only later stages, when symptoms of dementia are already evident.
The updated guidelines announced today cover the full spectrum of the disease as it changes over years. They describe the earliest preclinical stages of the disease, mild cognitive impairment, and dementia due to Alzheimer’s pathology. Importantly, the guidelines now address the use of imaging and biomarkers in blood and spinal fluid that may help determine whether changes in the brain and those in body fluids are due to Alzheimer’s disease.
Biomarkers are increasingly employed in the research setting to detect onset of the disease and to track progression, but cannot yet be used routinely in clinical diagnosis without further testing and validation. Read more: austindailyherald.com
