Nanotechnology could enable test for early Alzheimer’s Disease

PUBLISHED

Nanotechnology could be used to test blood for evidence of Alzheimer’s disease years before symptoms appear, researchers have said.

Scientists used nanotechnology to extract previously unseen blood signals of neurodegeneration in a mouse model of Alzheimer’s disease.

They say tests that capture early signs of neurodegeneration in blood offer enormous potential for those who suffer from the disease, as well as dementia patients, to receive effective treatment or manage their progressive condition before significant brain damage occurs.

Alzheimer’s disease can currently be diagnosed using brain scans only after someone has been showing behavioural symptoms, such as memory impairment. By the time symptoms emerge, it is often too late to treat patients effectively.
