Group of molecules for diagnosing Alzheimer’s disease

A group has been found molecules that may improve the early diagnosis of Alzheimer’s disease. This is the conclusion reached by a group of researchers from the Nutrition and Metabolic Health Group at the University of Rovira e Virgili (URV) in Tarragona.

Magazine Cell and biological sciences published the results of this study, which revealed 15 small non-coding RNA moleculeswhich are present in 85% of participants are at greatest risk development of the disease.

The sample of the experiment consisted of 192 people with mild cognitive impairment and risk presence of Alzheimer’s disease.

These discoveries, from a study in which the Pere Virgili Health Research Institute (IISPV) also collaborated, will make it possible to diagnose the disease in the most vulnerable patients. years ahead.

Currently, the disease is diagnosed using clinical symptomswhich are complemented neurological imaging tests to the patient. Also tests cerebrospinal fluid through lumbar puncture.

Research shows that integrating this RNA analysis in diagnostic methods, would improve the quality of patient care reducing the use of invasive procedures.

These molecules nucleotide chains short, which, despite the presence of genetic information, They do not have the ability to encode proteins, the university emphasized. Lead author of the study Laya Gutierrez-Torderaassured that these molecules “have the potential to improve the prognosis of Alzheimer’s disease and its early diagnosis.”
