Your nose could detect Alzheimer’s years before symptoms begin

Your nose could detect Alzheimer’s years before symptoms begin

Losing your sense of smell might signal Alzheimer’s far earlier than expected. Scientists found that immune cells in the brain actively destroy smell-related nerve fibers after detecting abnormal signals on their surfaces. This damage begins in early stages of the disease, well before cognitive decline. The discovery could help identify at-risk patients sooner and improve treatment timing.

Early warning sign of alzheimer’s

A recent study has found that a reduced sense of smell may be one of the earliest and most important signs of Alzheimer’s disease. Surprisingly this change can appear even before clear memory problems begin. Scientists from Germany including researchers at DZNE and Ludwig Maximilian University of Munich (LMU) have explored why this happens. Their findings show that the brain’s immune system plays a key role in this process.  However the problem …

Why does gut smell loss relate to Alzheimer’s?

Loss of smell as an early clue to Alzheimer’s A new finding points to smell impairment as a potential early indicator of Alzheimer’s disease—years before other classic symptoms appear. The key reported mechanism links early Alzheimer’s changes to the brain’s immune system. What the researchers…
