Concussions can cause us to lose our sense of smell. This, from researchers at University of Montreal.
This study analyzed 42 hospital patients involved in skiing accidents, within 24 hours of their accident: 20 of these individuals had mild concussions and 22 had broken bones but no concussions. The research team asked each individual to smell felt-tip pens and identify the odors, such as roses and garlic.
Researchers determined that more than half of the patients with mild concussions had a reduced sense of smell, compared to less than 25% of the patients with broken bones. Fortunately, a year later, these patients had a restored sense of smell.
Researchers say this study demonstrates the importance of reporting any loss of smell after an accident, as it might be an early indicator of a concussion and the need for medical attention.
