Scientists made a significant breakthrough in unfurling the possibility of using brain scans as a diagnostic tool to detect the possibility and progression of Alzheimer’s disease. Accumulation of amyloid plaques is considered to be the key factor in the onset of Alzheimer’s. This is being assisted by the deposition of Tau plaques which increases the chances of incidence of Alzheimer’s. Screening of the APOE gene variants gives the possibility of identifying people at risk from the condition from those who are safe.
It is reported from studies that deposition of tau plaques in the temporal lobe of cerebrum is a normal event as the brain ages. But presence of the same at parts of the brain beyond the median temporal lobe is a sure indication of rapid progression of Alzheimer’s. Though the number of people living with dementia is on the rise worldwide, still researches are hopeful that within a very short timespan it would be possible to check the progression of this disease. Brain scans using PET (POSITRON EMISSION TOMOGRAPHY) has showed tremendous potential in checking the number of amyloid and tau plaques much before brain death of the person suffering from Alzheimer’s. Though initially the study was carried out on a handful of people of different age groups, researchers were really encouraged about the findings and were determined to carry out a more determined insight to stop the plaques from creating havoc at old age.
