What Changes in Your Sense of Smell Could Reveal About Brain Health
We often move through the world without thinking much about our sense of smell. The scent of morning coffee, fresh laundry, or a familiar perfume usually blends into the background of daily life. But researchers are discovering that changes in smell may be more important than we once realized—especially when it comes to long-term brain health.
Why Smell Matters More Than You Think
Experts suggest that a persistent change in the ability to detect or identify scents may sometimes signal early neurological changes. According to research led by specialists such as Professor Davangere Devanand at Columbia University, the sense of smell is closely connected to areas of the brain involved in memory and emotion.
Unlike other senses, smell signals travel directly to brain regions such as the hippocampus, which plays a key role in memory, and the amygdala, which processes emotions. These are the same areas often affected early in conditions like Alzheimer’s disease and other forms of dementia. Because of this direct connection, changes in smell can sometimes appear before more noticeable symptoms, such as confusion or memory loss.
