Fats in the blood may predict who will get Alzheimer's disease

Scientists have developed a blood test that can diagnose who is at risk for Alzheimer's disease with ninety percent accuracy three years before symptoms appear. The blood test measures levels of 10 lipids, or fats in the blood that are already known to be risk factors for developing Alzheimer's disease.

The development of an early risk assessment for dementia and Alzheimer's disease (AD) means clinicians could intervene early when treatment would be most effective.

Alzheimer's disease rates are expected to soar as baby boomers become the largest segment of the US population, making treatment and management of AD a focus of researchers.

There is no cure for Alzheimer's disease that affects 35.6 million people worldwide. The disease is expected to strike 115.4 million people by 2050. Thee study's corresponding author Howard J. Federoff, MD, PhD, professor of neurology and executive vice president for health sciences at Georgetown University Medical Center suggests most drugs that are prescribed for AD are given too late in the disease process, which is why they fail.

Identifying those at risk early would mean new approaches to managing Alzheimer's disease.


"The preclinical state of the disease offers a window of opportunity for timely disease-modifying intervention," Federoff said in a press release. "Biomarkers such as ours that define this asymptomatic period are critical for successful development and application of these therapeutics."

All of the drugs developed have failed for Alzheimer's disease. Federoff explains biomarkers for the disease have been developed for the first time that can be used to help identify people at risk for Alzheimer's disease that could in turn help delay the onset of symptoms.

Can someone tell me which lipids were thought to be significant in the Alzheimer's lipid study?I am 78 & just very slowly beginning to get mid memory loss( mainly short term)Also can someone let me have the original scientific paper which first mentioned this work?
Hi Dr. McGarry - No, they did not say which lipids were tested exactly. The media contact at the research facility is Karen Teber E mail: You may want to contact directly to learn more.
