Personality-Based and GEMS-Adapted Care: Seeing Your Person as They Are Now

This guide helps you adapt your caregiving approach by honoring the person’s lifelong personality while meeting them where they are today. Dementia changes how someone expresses their core traits, but their essential self remains. By using Teepa Snow’s GEMS model and a positive, relationship-based approach, you can reduce conflict, increase cooperation, and find moments of genuine connection. The key is to know your person as they were, see them as they are now, and let go of what you can’t have while celebrating what’s still possible.

Key points

  • Know your person as they were, but see them as they are now—their lifelong personality still guides their needs and responses.
  • Use the GEMS model (Sapphire, Diamond, Emerald, Amber, Ruby, Pearl) to match your approach to their current abilities, not their past ones.
  • Adapt your communication style to their personality: direct and respectful for a former leader, gentle and slow for a shy person.
  • Offer two choices to preserve their sense of control without overwhelming them.
  • When they resist, pause and assess the person, the people (yourself), and the place before reacting.
  • Share a one-page personality profile with all caregivers to ensure consistent, person-centered care.

Why Personality Still Matters in Dementia

Even as dementia progresses, a person’s lifelong personality traits don’t vanish—they shift. Research shows that people with Alzheimer’s often become more neurotic (anxious, irritable), less extraverted (withdrawn, less social), and less conscientious (less organized, less able to follow through). But the core of who they are—their humor, their values, their favorite routines—remains. A person who was always a quiet bookworm will not suddenly become a party animal. A person who was fiercely independent will resist help, even when they need it. The mistake many caregivers make is treating the disease, not the person. As Teepa Snow says, 'Know your person as they were, but now see them as they are.' This means you don’t erase their history; you use it as a map to understand their current behavior and needs.

The GEMS Model: A Framework for Seeing Your Person Clearly

Teepa Snow’s GEMS model categorizes dementia stages using gemstone names: Sapphire (early, clear thinking), Diamond (still sharp but rigid), Emerald (green for early-mid stage, losing some abilities), Amber (mid-stage, sensory changes), Ruby (late stage, deep emotional connection), and Pearl (end stage, withdrawn). Each gem has a different set of abilities and challenges. A person who was always a 'take-charge' leader may become frustrated when they can’t follow a recipe (Diamond stage). A person who loved social gatherings may become overwhelmed by noise (Amber stage). By identifying which gem your person is in, you can adapt your approach to match their current abilities, not their past ones. This is not about labeling—it’s about seeing clearly so you can respond with compassion.

The Relationship Guide: Using Their History to Build Trust

Your relationship with the person is your most powerful tool. If they were a teacher, use a calm, instructive tone. If they were a jokester, use humor. If they were a private person, give them space and choices. The Alzheimer’s Association emphasizes that person-centered care means prioritizing individual preferences, routines, and sources of joy. For example, a person who always drank coffee and read the newspaper may still enjoy holding the paper and sipping coffee, even if they can’t understand the words. A person who loved gardening may find peace in touching soil or smelling flowers. By weaving their history into your daily interactions, you honor their identity and reduce the fear and confusion that often trigger distress.

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

Step-by-step

  1. Step 1: Identify their lifelong personality type. Ask yourself: Were they introverted or extroverted? Organized or spontaneous? A leader or a follower? A worrier or easygoing? Write down three core traits. Use these as a lens to interpret their current behavior. For example, a lifelong worrier may now express anxiety as repetitive questions or restlessness.

  2. Step 2: Determine their current GEMS stage. Observe their abilities: Can they follow multi-step instructions? Do they get overwhelmed by noise or crowds? Are they more emotional or withdrawn? Use the GEMS descriptions to match their current functioning. This will guide your communication and activity choices.

  3. Step 3: Adapt your communication style to their personality and stage. For a person who was always direct and independent (Diamond stage), avoid baby talk or commands. Instead, say, 'I need your help with this—could you hold this towel for me?' For a person who was shy and now is in Amber stage, approach slowly, speak softly, and give them time to process. Use their name and a gentle touch on the arm before speaking.

  4. Step 4: Use their favorite activities as bridges, not demands. If they loved cooking, invite them to stir a bowl of dry beans or tear lettuce—don’t expect them to follow a recipe. If they loved music, play their favorite songs from their youth and sing along. The goal is engagement, not accomplishment. Watch for signs of frustration or waning attention, and end the activity on a positive note.

  5. Step 5: Create a predictable routine that honors their preferences. A person who was a morning person will do better with bathing and dressing early. A night owl may resist morning care but cooperate in the afternoon. Schedule challenging tasks (like bathing or doctor visits) during their best time of day. Use visual cues (like laying out clothes in order) to reduce confusion.

  6. Step 6: Use the 'Positive Approach to Care' (PAC) technique: approach from the front, at eye level, with a warm smile. Say their name, state your intention simply, and wait for a response. For example, 'Hi, Mom. It’s time for lunch. I have your favorite soup.' Avoid asking open-ended questions like 'What do you want to eat?' which can overwhelm. Offer two choices: 'Would you like the red cup or the blue cup?'

  7. Step 7: When they resist care, pause and assess the 'three layers'—the person, the people, and the place. First, check the person: Are they in pain, hungry, tired, too hot or cold? Second, check yourself: Did you rush, use a harsh tone, or invade their space? Third, check the environment: Is it too noisy, bright, or cluttered? Adjust one layer at a time. Often, a simple change—like dimming the lights or playing soft music—can transform their mood.

  8. Step 8: Let go of tasks that no longer serve them. If they were always a perfectionist about cleaning, don’t insist on a spotless house. If they were a private person, don’t force group activities. Instead, find one-on-one moments that feel safe. As one caregiver shared, 'I focus on the person, not the label or the disease.' This shift from task-oriented to relationship-oriented care reduces your stress and theirs.

  9. Step 9: Share their personality profile with other caregivers. If you use respite care, a day program, or a facility, give staff a brief written summary: 'Dad was a high school principal. He responds best to a calm, respectful tone. He loves jazz music and hates being rushed. He becomes anxious in crowds.' This helps others see the person, not the patient. As one expert noted, 'When you’ve seen one person with dementia, you’ve only seen one person.'

  10. Step 10: Reassess regularly. Dementia changes, and so will their needs and responses. What worked last month may not work today. Stay flexible. Use a simple weekly check-in: What went well? What was hard? What can I try differently? Adjust your approach as their gem shifts. Remember, the goal is not to fix them but to connect with them.

What not to do

  • Don’t treat them like a child or use 'elderspeak' (baby talk, pet names like 'sweetie' or 'honey' unless they always used them). This can feel demeaning and trigger resistance. Instead, use the same respectful tone you would have used with them before dementia.

  • Don’t force them into activities they never enjoyed. If they hated bingo before, they will likely hate it now. Forcing it can cause agitation. Instead, offer activities that align with their lifelong interests—even if it’s just folding laundry or sorting coins.

  • Don’t correct their reality or argue about facts. If they say they need to go home (when they are home), don’t say 'You are home.' This can cause distress. Instead, validate the feeling: 'You miss home. Tell me about your home.' Then redirect to a comforting activity.

  • Don’t assume their personality has completely changed. A sudden 'personality change' may actually be a sign of pain, infection, or medication side effect. Always rule out medical causes first. Discuss any sudden changes with their clinician.

  • Don’t take their resistance personally. If they refuse care, it’s not about you—it’s about their fear, confusion, or loss of control. Step back, breathe, and try a different approach. As one expert said, 'Move out of a reflex and into a response.'

  • Don’t ignore your own personality and needs. If you are naturally impatient, you may need to practice slowing down. If you are a problem-solver, you may need to accept that some problems have no solution. Caregiver self-care is not optional—it’s essential for sustainable care.

Practical tools

  • The 'Know Your Person' One-Page Profile

    Create a single-page document with: their name, their three core personality traits, their favorite activities, foods, music, and phrases that calm them. Include their GEMS stage and what helps them feel safe. Share this with all caregivers, family, and facility staff. Update it every few months.

  • The Two-Choice Script

    When offering a choice, always give two options that are both acceptable to you. Say: 'Would you like to wear the blue sweater or the red one?' or 'Would you like to walk now or after lunch?' This gives them a sense of control without overwhelming them. Avoid 'Do you want to take a shower?' (too open-ended) or 'You need to shower now' (too commanding).

  • The 'Visual Cue' Setup

    Use their environment to guide behavior without words. For a person who loved coffee, set up a small coffee station with a mug and a jar of beans (for smell). For a person who loved gardening, place a pot of soil and a trowel on the table. Visual cues can trigger positive memories and reduce the need for verbal instructions.

  • The GEMS Stage Quick Reference Card

    Print a small card with the six GEMS stages and their key characteristics. Keep it in your wallet or phone. When you’re feeling frustrated, look at the card and ask: 'Which gem am I seeing right now? What does this stage need?' This helps you shift from frustration to understanding.

  • The 'Pause and Assess' Checklist

    When a behavior occurs, run through this mental checklist: (1) Person: Are they in pain, hungry, tired, too hot/cold? (2) People: Did I approach too fast, use a harsh tone, or invade their space? (3) Place: Is the room too noisy, bright, or cluttered? Change one thing at a time and observe the response.

  • The 'Favorite Things' Activity Kit

    Assemble a small box or bag with items that reflect their personality: a familiar book, a soft scarf, a photo album, a favorite lotion scent, a playlist of their music. When they are restless or anxious, offer the kit. Let them choose what to engage with. This is especially helpful during sundowning or transitions.

Discuss with your clinician

If you notice a sudden, dramatic personality change (e.g., from calm to aggressive, or from social to withdrawn), discuss with a doctor to rule out infection, pain, or medication side effects.

Ask your clinician about the GEMS model and whether it aligns with your loved one’s current diagnosis and stage. Some stages may require different medication or therapy approaches.

If the person with dementia is on medications for mood or behavior, discuss how these may interact with their personality traits. For example, a person who was always anxious may need different support than one who was always easygoing.

If the person is experiencing hallucinations or delusions that seem tied to their personality (e.g., a former teacher who thinks they are still grading papers), ask a clinician how to respond without causing distress.
