The GEMS Approach to Dementia Staging: A Brighter, More Practical Way to Understand Your Loved One

Traditional dementia stages (like the 7-stage GDS or 3-stage model) can feel rigid and scary, often leaving you trying to fit your loved one into a box that doesn't quite work. The GEMS approach, created by dementia care expert Teepa Snow, offers a different way: instead of focusing on what's lost, it highlights what remains and what support is needed right now. Think of it like looking at a gemstone under different lights—each stage is a unique 'gem' with its own beauty and challenges. This article will explain how GEMS works, how it differs from traditional staging, and give you concrete steps to use it today to reduce stress and improve care.

Key points

  • The GEMS approach (Sapphire, Emerald, Amethyst, Ruby, Pearl, Diamond) focuses on what remains, not what's lost, reducing caregiver grief and anxiety.
  • Unlike traditional stages, GEMS is fluid—your loved one can move between states, and that's normal.
  • Use GEMS to communicate with your care team: describe the current gem and its specific needs, not a stage number.
  • Track functional changes weekly with bullet points, not by trying to fit your loved one into a rigid box.
  • The GEMS approach works across all dementia types, but you may need to adjust for specific conditions like LBD or FTD.
  • Teach the GEMS language to everyone involved in care to create consistency and reduce conflict.

What Is the GEMS Approach and Why Does It Matter?

Traditional dementia staging models, like the Global Deterioration Scale (GDS) or the Functional Assessment Staging Tool (FAST), are helpful for doctors to estimate life expectancy and track cognitive decline. But for you as a caregiver, these stages can feel like a cold checklist of losses—'stage 4 means they can't do this, stage 5 means they'll lose that.' This often leads to anxiety, grief, and a focus on what's gone rather than what's still there. The GEMS approach flips that script. Developed by Teepa Snow and her Positive Approach to Care team, it uses gemstone names—Sapphire, Emerald, Amethyst, Ruby, Pearl, and Diamond—to describe the changing abilities and needs of a person living with dementia. Each gem represents a different 'state' of being, not a fixed stage, and it emphasizes the person's retained strengths and the care strategies that work best for that state.

How GEMS Differs from Traditional Staging: A Shift in Perspective

The biggest difference is that GEMS is not about predicting the future or labeling your loved one. Traditional stages often give a false sense of clarity, as Dr. Camille Sinclair warns: they only show a few symptoms and miss the important functional changes you need to track. GEMS, on the other hand, is a tool for communication and support. It helps you ask: 'What support does my loved one need right now, based on what I'm seeing?' Instead of saying 'Dad is in stage 6,' you might say 'Dad is in a Ruby state—he needs help with all daily tasks but still enjoys music and touch.' This shifts your focus from loss to connection. It also acknowledges that people can move between gems—they might be an Amethyst in the morning (needing some help but still social) and a Ruby by evening (very confused and needing full assistance). This fluidity is more realistic and less frightening.

The Six GEMS States at a Glance

Here's a quick overview of the six GEMS states, from highest function to highest need: - **Sapphire (Early Stage):** The person is still very capable, but may have some memory lapses or trouble with complex tasks. They are like a sapphire—hard, clear, and valuable, but may need a gentle polish. Care focuses on maintaining independence and using memory aids. - **Emerald (Early-Mid Stage):** The person has more noticeable changes, like trouble with planning or finding words. They are like an emerald—beautiful but with natural inclusions (flaws) that need careful handling. Care involves simplifying routines and using visual cues. - **Amethyst (Mid Stage):** This is often the longest state. The person may be restless, anxious, or have trouble with communication. They are like an amethyst—vibrant but with a tendency to 'crack' under stress. Care focuses on calming environments, redirection, and validation. - **Ruby (Late-Mid Stage):** The person needs help with almost all daily activities, may not recognize familiar faces, and may have physical changes like trouble walking. They are like a ruby—precious but needing a strong setting (full support). Care involves gentle hands-on assistance and sensory engagement. - **Pearl (Late Stage):** The person is very frail, often bed-bound, and may have lost most verbal communication. They are like a pearl—formed from irritation, but smooth and beautiful. Care focuses on comfort, pain management, and connecting through touch and voice. - **Diamond (End of Life):** The person is nearing the end of life, often sleeping most of the time and having irregular breathing. They are like a diamond—formed under extreme pressure, but brilliant and enduring. Care is about peace, dignity, and saying goodbye.

Remember: these are not rigid boxes. Your loved one may show traits of multiple gems at once, and that's okay.

General caregiving information, not medical advice. Check medications and major care changes with your clinician.

Step-by-step

  1. Each week, note what your loved one can still do and where they need help—like 'still makes toast but forgets to turn off the stove.' This tracking of functional decline is more useful than any stage number.

  2. Before assuming a shift to a new gem state, check for unmet needs: hunger, thirst, pain, bathroom, or overstimulation may cause a temporary change.

  3. Match care to the current gem state—e.g., for agitation, try folding towels; for withdrawal, use gentle touch and a soft voice. Let the gems guide 'what works now.'

  4. Use GEMS language with doctors, aides, and family: 'Mom is in a Ruby state—needs full help with bathing, but still smiles at her favorite music.' This clarifies abilities and needs.

  5. Teach care partners the same GEMS vocabulary so everyone can adapt together. Post a simple chart on the fridge to reduce confusion.

  6. For medical needs (hospice, insurance), keep traditional stages but pair them with GEMS to see the person, not just the disease.

What not to do

  • Do NOT force one gem label—traits may mix (e.g., feeds self but doesn't recognize you). Observe and adapt daily.

  • Do NOT use stages to predict timeline or compare with others—each journey is unique. GEMS focuses only on the present.

  • Do NOT forget your own state—check if you need support each day to care well.

Practical tools

  • GEMS State Quick Reference Card

    Print a card listing all six gems with retained abilities and care tips. Keep it on the fridge or in your wallet. When stuck, glance at it and ask 'Which gem fits now?' then try the suggested approach.

  • The 'What Remains' Journal

    Each day, write one thing your loved one can still do—e.g., 'Dad hummed along to You Are My Sunshine.' This shifts focus from loss to ability and highlights moments of connection.

  • Gem-Shift Alert System

    Use color-coded sticky notes on the door or calendar (blue=Sapphire, green=Emerald, purple=Amethyst, red=Ruby, white=Pearl, clear=Diamond) so everyone instantly knows the day's approach.

  • GEMS-Based Activity Menu

    List activities per gem state: Sapphire—crosswords; Emerald—folding laundry; Amethyst—listening to music; Ruby—hand massage; Pearl—gentle hair brushing; Diamond—quiet hand-holding. Rotate as the gem changes.

Discuss with your clinician

Ask your doctor: 'Based on the GEMS approach, what state do you think my loved one is in, and what medical supports would be appropriate for that state?'

If your loved one is in a Ruby or Pearl state, discuss whether hospice or palliative care might be appropriate. The GEMS approach can help frame this conversation around comfort rather than 'giving up.'

If you notice sudden shifts in GEMS states (e.g., from Emerald to Ruby overnight), discuss this with the clinician—it could signal an infection, medication side effect, or other medical issue that needs attention.

Ask about medications that might help with specific GEMS-related challenges, like agitation in an Amethyst state or sleep issues in a Ruby state. Always discuss risks and benefits.
