In preparation for more tools that detect and measure the biology associated with Alzheimer's and other dementias earlier and with more accuracy, an Alzheimer's Association-led Workgroup has published appropriate use criteria (AUC) for lumbar puncture (spinal tap) and spinal fluid analysis in the diagnosis of Alzheimer's disease, according to a recent press release.
The AUC is available online by Alzheimer's & Dementia: The Journal of the Alzheimer's Association as an article in press, corrected proof.
"Early and accurate diagnosis of Alzheimer's disease is critical as therapies that have the potential to stop or slow the progression of the disease become available," said Maria C. Carrillo, Ph.D., Chief Science Officer at the Alzheimer's Association. "These criteria will arm medical professionals with necessary guidance when the use of lumbar puncture is an appropriate part of the process to diagnose Alzheimer's disease and other dementias, thereby giving people with dementia and their families the possibility of a head start in preparing for the course of their disease."
Alzheimer's disease is commonly diagnosed by a thorough examination of physical health, medical history and assessment of memory, thinking and reasoning. Lumbar puncture, while not currently in routine clinical practice in the U.S., is anticipated to be a safe and cost-effective way to retrieve cerebrospinal fluid (CSF) to test for biological markers of Alzheimer's disease, potentially delivering valuable diagnostic information to clinicians and their patients earlier in the course of the disease.
The Workgroup's efforts complement the 2013 AUC for brain amyloid PET scans developed by the Society of Nuclear Medicine and Molecular Imaging (SNMMI) and the Alzheimer's Association.
