New research offers fresh hope for diagnosing Alzheimer’s via a blood test, potentially years before symptoms emerge.<\/p>\n

The memory-robbing disease has no set test, with specialists assessing suspected patients via memory analyses, mental-agility evaluations and brain scans.<\/p>\n

The concept of an Alzheimer’s blood test is not new, with past studies suggesting biomarkers circulate in a patient’s blood before they show signs of the disease.<\/p>\n

Cutting-edge technology has now enabled scientists from the University of Manchester to uncover previously-unseen blood biomarkers in mice with the memory-robbing condition.<\/p>\n

Alzheimer’s is considered incurable, however, treatments can temporarily ease symptoms, with these being more effective when administered early in the disease’s onset.<\/p>\n

Alzheimer’s is the most common form of dementia, an umbrella term for syndromes associated with an ongoing loss of brain function.<\/p>\n

More than 850,000 people had dementia in the UK in 2019,\u00a0with Alzheimer’s affecting 50% to 75% of these patients. In the US,\u00a0over 6 million people have Alzheimer’s.<\/p>\n

Blood biomarkers are believed to be present in Alzheimer’s patients, however, their minute level makes them difficult to detect.<\/p>\n

The Manchester scientists therefore created a specific nanotechnology \u2013 “the study and application of extremely small things” \u2013 that allowed them to extract blood signals from mice with the disease.<\/p>\n

These signals could then be magnified, enabling the team to look for signs of Alzheimer’s.<\/p>\n

“Hidden information in blood is likely to echo the complex cascade of events occurring in the brain of Alzheimer’s disease patients,” said lead author Dr Marilena Hadjidemetriou.<\/p>\n

“We wanted to engineer a nanotechnology blood-mining platform in order to uncover this information and identify early signs of Alzheimer\u2019s disease at the pre-disease state, before the onset of amyloid plaque formation in the brain.\u2019”<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
