Early Memory & Cognitive Health Screening
A free, validated screening questionnaire to help you or a loved one check everyday memory changes—and generate a clear report ready for your doctor.
Over half of adults noticing memory decline have never mentioned it to a healthcare provider.
Average wait time between first noticing cognitive changes and receiving a medical evaluation.
Early mild cognitive changes are frequently missed in rushed 15-minute routine checkups.
Patient pages give a plain-English summary & card breakdown. The final page provides clinical scores for your physician.
How CogniGlass Works in 3 Simple Steps
Designed for effortless reading, zero medical jargon for you, and complete clinical precision for your doctor.
Choose Who It Is For
Select "For Myself" (which includes 18 everyday questions plus 3 short word-memory, date, and sequence activities) or "For a Loved One" (an observational questionnaire for a spouse, parent, or relative).
Check Everyday Routines & Health Factors
Move one card at a time at your own pace. Along with everyday memory and routine questions, we check for common sleep aids, allergy pills, and health conditions (like sleep quality, thyroid, or hearing) that can cause reversible "brain fog."
Print or Save Your Report
Receive your results immediately with no sign-up or email required. Keep the Patient Summary & Card Breakdown pages for yourself and hand the Physician Report (final page) directly to your primary care doctor/specialist at the start of your next appointment.

Construct-Aligned Alzheimer's & Dementia Screening Architecture
To eliminate redundant questions while giving physicians comprehensive data for Alzheimer's and Mild Cognitive Impairment (MCI) risk assessment, our original 18-item questionnaire and 3 brief activities compute construct-aligned estimates across 6 established clinical domains:
1. 8-Item Change Index (0–8)
An 8-item intra-individual change index (AD8-aligned construct) that detects early longitudinal shifts in memory, temporal orientation, everyday judgment, and hobbies (clinical cutoff ≥ 2).
2. 14-Item Subjective Drift Index (0.0–14.0)
A 14-item subjective 1-year cognitive drift index (CFI-aligned construct) designed to capture subtle, early perceived cognitive decline before formal bedside testing turns abnormal (cutoff ≥ 4.0).
3. 10-Item Functional Independence Index (0–30, Prorated)
A 10-item instrumental daily activities scale (FAQ / IADL-aligned construct) measuring independence in complex tasks (finances, forms, shopping, meal prep, travel), with proration for tasks never performed historically (cutoff ≥ 9).
4. 4-Word Controlled Cued Recall (0–8)
Uses 4-word controlled category learning and delayed category-cued recall (Buschke paradigm) from an original 160-word bank to help physicians distinguish retrieval slowing (which improves with hints) from true encoding deficits.
5. Temporal Orientation (0–4)
Standardized 4-item bedside time orientation assessment (Year, Month, Date of Month with ±1 day tolerance, and Day of the Week) modeled on standard primary-care temporal screens.
6. Digital Trail-Making A & B
Measures Part A motor tapping speed (1–5) and Part B alternating executive switching (1-A-2-B-3-C-4-D-5-E), subtracting baseline motor speed so physical arthritis or tremor is not mistaken for cognitive slowing.
Note: Construct-aligned pre-visit estimates using original CogniGlass items; not an official administration of the copyrighted AD8®, ADCS CFI, or Einstein MIS.
Privacy, Ethics & Non-Diagnostic Notice
100% Private & Anonymous: CogniGlass never asks for your name, email address, phone number, street address, or birth date. Your complete report is generated directly in your browser. If you optionally leave the research box checked on the setup screen, only de-identified numeric scores are contributed to our public-health research cohort.
Communication Aid, Not a Diagnosis: CogniGlass is designed to organize observations and performance metrics for a primary care physician, geriatrician, or neurologist. It does not replace a formal medical evaluation.
Psychometric Copyright, Licensing & Construct-Alignment Disclosure: CogniGlass uses 100% original question wording, an original 160-word semantic stimulus bank, and custom bedside micro-tasks to generate construct-aligned pre-visit estimates; it is not an official administration of any third-party copyrighted instrument:
- Instruments Subject to Commercial Copyright / Licensing: The official AD8® Dementia Screening Interview (copyrighted & trademarked by Washington University in St. Louis; free for non-profit clinical/research use, commercial license required), the Alzheimer's Disease Cooperative Study Cognitive Function Instrument (ADCS CFI) (copyrighted by UC San Diego / ADCS; permission required for commercial use), and the official Buschke Memory Impairment Screen (MIS) word forms (copyrighted by Albert Einstein College of Medicine / Yeshiva University; commercial license required) are proprietary instruments. CogniGlass does not reproduce their verbatim forms or proprietary word lists, and instead computes an original 8-Item Change Index (AD8-aligned construct), 14-Item Subjective Drift Index (CFI-aligned construct), and 4-Word Controlled Cued Recall (Buschke paradigm).
- Public-Domain / Open Clinical Paradigms: The Trail-Making Test (Parts A & B) paradigm (originally developed for the 1944 U.S. Army Individual Test Battery), standard 4-item Calendar & Temporal Orientation questions (Year, Month, Date, Day of Week), the Anticholinergic Cognitive Burden (ACB) / AGS Beers Criteria® medication class groupings, and the general 10-domain Instrumental Activities of Daily Living (IADL / Pfeffer FAQ) functional framework represent open clinical literature or U.S. government public-domain paradigms, implemented here with original CogniGlass wording and motor-normalized scoring math.
- Intended Non-Commercial Scope & Normative Notice: CogniGlass is provided as a free public-health and educational pre-visit communication aid. All trademarks and instrument names cited in clinical literature references remain the property of their respective academic institutions. Because items are harmonized into a single 18-question intake flow and administered digitally without a psychometrician present, scores represent construct-aligned pre-visit screening estimates rather than official normed administrations.
