Detecting whether or not someone is going to recrudesce Alzheimer ’s would revolutionize the intervention of a severe disease that bear upon millions of hoi polloi each year . Now there could be hope on the horizon as investigator claim they have founda non - invasive accurate testfor the condition .
One of the main problems with judge to formulate a way to cover Alzheimer ’s is the simple fact that by the prison term someone has been diagnosed with the disease , it is often too late . There are no known ways to reverse Alzheimer ’s once it has set in , meaning that there has been a big deal of focus on trying to find a way in which doctor and researchers can detect the disease before the symptoms set in .
Again , however , this raises issue . In guild to corroborate that a reliable mark for Alzheimer ’s has been identified , researchers have to monitor the affected role in their study to see which ones go on to develop the disease . If they deal to recognise any markers , by that point it is too late to do anything to keep its progression .
But this has not prevented many radical of researchers from hunt for theelusive biomarkers , with many dissimilar routeshaving been explored . One such avenue is wait in the cerebrospinal fluid of patients for protein associated with Alzheimer ’s called beta - amyloid , as it has been suggest that these may change with the patterned advance of the disease . But others are peachy to get hold non - invasive approaches .
This latest sketch , published inHuman Brain Mapping , used magnetoencephalography to scan the genius of people reporting the symptoms of Alzheimer ’s as well as those of people who were not , register their encephalon bodily function . They found that in healthy people , the prefrontal regions of the genius reacted to auditory tests , while in people with Alzheimer ’s symptoms , they did not .
“ It is highly probable that these individuals were captured in a presymptomatic [ Alzheimer ’s ] phase angle since they show both neuropsychological and neurophysiological impairments characteristic of an [ Alzheimer ’s ] type of dementia , although they did not yet meet clinical criteria for the early phase of diagnostic [ Alzheimer’s],”saidSanja Josef Golubic , the study ’s lead author .
The scientists exact that their trial is extremely precise in pick up on the early signs of the disease , and if it establish successful in further test , it could be significant . It is significant , however , to note that the sample sizing for this initial research was very small , with only 20 people tested , so more evidence will be needed before it can be used clinically .
