How This Sign During Showering May Signal Early Alzheimer’s Disease

Our sense of smell, or olfaction, is more than just a means to enjoy pleasant aromas; it’s intricately linked to brain function and memory.

The olfactory system has direct connections to the hippocampus and amygdala, areas of the brain responsible for memory and emotion. This close relationship means that changes in smell perception can reflect alterations in brain health.

In the context of Alzheimer’s disease, the olfactory bulb and related brain regions are among the first to exhibit pathological changes. This early involvement can lead to a reduced ability to detect and identify odors, a condition known as anosmia. Notably, this sensory decline can precede more recognizable cognitive symptoms by several years.
