Understanding the SAGE Test for Early Alzheimer's Detection
The SAGE test is a short self-administered cognitive screening tool designed to detect early signs of Alzheimers disease and other brain impairments. SAGE stands for Self-Administered Gerocognitive Exam.
The SAGE test was created by renowned neurologist Dr. Douglas Scharre as an affordable and practical way to identify mild cognitive issues in the earliest stages when lifestyle changes and treatment interventions may help delay progression.
About Dr. Douglas Scharre and His Motivation to Develop the SAGE Test
Dr. Douglas Scharre is an accomplished cognitive neurologist and Director of the Division of Cognitive Neurology at Ohio State Universitys Wexner Medical Center.
After decades specializing in memory disorders and dementia care, Dr. Scharre recognized the pressing need for simple, accurate tools to detect mild cognitive impairment (MCI) and early-stage Alzheimer's.
By developing an inexpensive and easy-to-administer cognitive exam, Dr. Scharre aimed to empower more healthcare providers and the general public to identify these conditions sooner.
How the SAGE Screening Test Works
The SAGE test includes brief assessments across several cognitive domains most impacted by Alzheimers disease and related dementias:
- Orientation
- Language
- Reasoning/Computation
- Visuospatial Functioning
- Executive Function
- Memory Recall
Administration only takes about 15 minutes and scoring is simple, with abnormal results in two or more areas signaling reason for full diagnostic workup.
The SAGE test is available online or as a paper version. No special training is required to give or interpret the screening.
Advantages of the SAGE Test for Cognitive Screening
Compared to longer pen-and-paper exams or costly PET brain scans, the SAGE test offers many advantages for clinicians and patients concerned about brain health including:
Minimally Invasive
The SAGE exam uses non-invasive paper and verbal assessments, avoiding intimidating high-tech medical tests.
Patient Friendly
The self-administered format empowers patients and doesnt rely on having friends/family notice changes.
Accessible & Affordable
Freely available online or for under $30 to purchase paper kits, making cost no obstacle for screening.
Efficient
The SAGE test takes just 15 minutes to complete, with easy instant scoring.
Sensitive for Subtle Changes
Design detects early cognitive abnormalities when lifestyle interventions and treatment may help most.
Interpreting SAGE Test Results
The SAGE exam provides an overall score plus individual subsection scores to reveal areas of concern. In general:
- Scores 85-100 = Normal cognition
- 80-84 = Possible mild cognitive impairment
- 70-79 = Likely early dementia
- Under 70 = Significant cognitive impairment
However, any abnormalities should prompt fuller evaluation, as causes range from treatable conditions like depression or vitamin deficiencies to Alzheimers disease.
Follow-Up Testing After Abnormal SAGE Results
If SAGE scores reveal deficits, Dr. Scharre advises comprehensive workup including:
- Physical exam to check vision, heart, etc.
- Lab tests to assess hormone, nutrient, and protein levels
- Genetic testing to identify dementia risk factors
- PET scan provides definitive diagnosis if Alzheimers suspected
Catching subtle decline early expands options to slow progression toward dementia through medications, dietary changes, brain training exercises, social engagement, and more.
The SAGE Test as a Routine Dementia Screening Tool
Due to high patient acceptability and accuracy for detecting early cognitive changes, Dr. Scharre envisions the SAGE test becoming a routine preventative screening tool for older adults like colonoscopies or mammograms.
Widespread use of simple, self-administered screenings could revolutionize early intervention against dementia on a population scale.
Dr. Scharre continues advocating for cognitive check-ups to become standard protocol, driving improved brain health and quality of life as people age.
Just as addressing heart disease risks early prevents later decline, detecting cognitive issues sooner results in better outcomes. Public access to easy, affordable brain screening empowers patients and physicians to get ahead of dementia.
FAQs
Who created the SAGE dementia screening test?
The SAGE test was developed by Dr. Douglas Scharre, an accomplished cognitive neurologist and Director of Cognitive Neurology at Ohio State University’s Wexner Medical Center.
What does the SAGE test assess?
The SAGE exam evaluates key cognitive areas impacted by Alzheimer's disease and dementia including orientation, language, reasoning, visuospatial skills, executive function, and memory recall.
How long does the SAGE test take?
Administering the SAGE test takes approximately 15 minutes. It is a simple, efficient screening tool for subtle cognitive decline.
What should I do if I score poorly on SAGE?
Abnormal SAGE results in two or more subgroups signals potential cognitive impairment requiring fuller evaluation. Follow up with physical/lab exams, genetic testing, and potentially PET scan for definitive Alzheimer’s diagnosis.
