At-Home Smell Tests Help Detect Alzheimer’s Early

A recent study published in Nature: Scientific Reports discusses the AROMHA Brain Health Test (ABHT), an at home olfactory assessment designed to screen for cognitive impairment. This at-home test evaluates odor identification, discrimination, memory, and intensity, offering a noninvasive method to detect early signs of cognitive decline.​

What They Found:

• The test successfully identified differences between healthy individuals, people with mild cognitive impairment, and those experiencing subjective cognitive complaints.

• Performance on the test decreased with age, but scores were notably lower for people with mild cognitive impairment.

• The test worked equally well whether supervised or done independently at home.

• Results were consistent for both English and Spanish speakers, showing potential for broad use regardless of language.

  
  

Conclusion:The ABHT smell test is a promising, easy-to-use tool for screening individuals who might be at risk for dementia, potentially allowing earlier interventions to maintain cognitive health.

Why It Matters:

Olfactory dysfunction is one of the earliest indicators of neurodegenerative diseases like Alzheimer's. The ABHT provides a cost-effective, accessible tool for early screening, which is crucial for timely intervention and management.​

Takeaway:

Incorporating olfactory assessments into routine health checks could revolutionize early detection of cognitive impairments. As research progresses, such tools may become integral in proactive brain health maintenance.​ Until then, you can assess yourself at home and train your brain.
