A nanotechnology nasal spray is being developed that could transform the early detection and treatment of Alzheimer's. <\/p>\n
The device shoots tiny magnetic particles into the nose which enter the bloodstream and are carried to the brain. <\/p>\n
Each particle is fused to an antibody that targets and binds to rogue molecules believed to play an early role in the disease. <\/p>\n
Magnetic resonance imaging (MRI) can detect both the particles and the molecules. <\/p>\n
To date scientists have only tested the technique in the laboratory on human brain tissue cultures. <\/p>\n
But if it can be shown to work in human patients it could lead to a major leap forward in managing Alzheimer's. <\/p>\n
Scientists believe the changes that lead to Alzheimer's begin decades before the first symptoms appear. <\/p>\n
By the time a patient is diagnosed the disease is already far advanced, and experts suspect that is the main reason why a number of promising drugs have failed in patient trials. Identifying the disease much earlier could make it far easier to treat. <\/p>\n
Details of the new research were presented at the annual meeting of the Society for Neuroscience in New Orleans, US. <\/p>\n
Lead scientist William Klein, from Northwestern University, Chicago, said: \"We have created a probe that targets a unique marker of Alzheimer's disease. This technology is a promising tool for early AD diagnosis and for evaluating the efficacy of investigational new drugs at early stages of the disease.\" <\/p>\n<\/p>\n
