Smell Identification Test
In a long-term study involving more than 1,000 participants, researchers asked volunteers to identify a variety of common everyday scents.
Examples included:
• Soap
• Smoke
• Rose
• Leather
The researchers found that participants who had greater difficulty identifying these familiar odors were more likely to develop cognitive impairment during follow-up.
When combined with brief memory assessments, smell testing provided useful information and, in some situations, offered
results comparable to more advanced screening approaches.
Why Early Detection Matters
Early identification of cognitive changes may allow people to seek medical evaluation sooner and discuss lifestyle strategies, treatment options, or additional testing
