An early diagnosing is necessary to intervene and slow down the progression of neurodegenerative disease , such as Alzheimer ’s disease ( AD ) . regrettably , the disease typically is n’t spotted until symptoms have already appeared and amyloid plaques have start to accumulate and cause impairment to the brain . A new blood line test claim to be capable to accurately identify Alzheimer ’s disease 10 twelvemonth before the onset of symptom .
The paper was published inThe Journal of the Federation of American Societies for Experimental Biology . lead-in author Dimitrios Kapogiannis from the National Institute on Aging in Baltimore presented the research this workweek at the2014 coming together of the Society for Neurosciencein Washington , DC .
The bloodline test was performed on 174 patient role with various degree of neurologic wellness : 84 of the participant were tidy adults , 20 were elderly adults with no dementia , and 70 had been diagnose with advertizing . The researchers also had accession to flash-frozen blood sample from 20 of the advertizement patients that had been taken anywhere from 1 - 10 years prior to the diagnosing .
“ This subject field demo that insulin resistance is a major key nervous organization metabolic abnormality in AD that contributes to neural cell hurt , ” senior author Edward Goetzl of the National Institute on Aging said in apress release . “ As insulin electric resistance is a known condition in case 2 diabetes mellitus and is treatable with several classes of existing drugs , these treatments may be utile as part of a multi - agent program for advert . ”
There have been other AD test announced this year that use different biomarkers to predict disease . Based on 10 proteins found in the blood , a team from Oxford predict onset of advertizing within a yr for over 1,100 participants , with87 % truth . A squad from Georgetown University screened for 10 lipoid in 525 player , and was90 % accuratein betoken disease in three age .
“ We believe our assays will prove instrumental in identifying early - stage AD patients for entry in clinical trials and thereby help to enrich the sketch population . We invite pharmaceutic fellowship and university researcher to adjoin us about collaborating or partnering to father additional data point , ” point out John Osth . Osth is President and CEO ofNanoSomiX , a California - based biotech society that helped fund the research and desire to make the test commercially practicable in the futurity .
