When we think of Alzheimer’s disease, memory loss and confusion often come to mind. However, recent research suggests that a subtle change in our daily routine—specifically, a diminished sense of smell during activities like showering—might be an early indicator of this neurodegenerative condition.
The Overlooked Sense: Olfaction and Its Role in Brain Health
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.
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.
