Tracking Personal Baselines to Detect Significant Change

When you're caring for someone with dementia, it can feel like changes happen so gradually that you're not sure if anything is really different—or so suddenly that you panic. Tracking a personal baseline means you have a simple, honest snapshot of how your loved one is doing right now, so you can spot when something truly shifts. This isn't about becoming a medical expert; it's about being a careful observer with a few practical tools. You can do this, and it will help you feel more confident and less alone.

Key points

  • A baseline is a simple record of what is normal for your loved one right now—not years ago.
  • Track just a few key areas: eating, sleeping, mood, communication, and mobility.
  • Write down one sentence a day. It takes 30 seconds and can prevent a crisis.
  • A sudden change from baseline is a medical red flag—don't assume it's 'just dementia.'
  • Use the 'sudden change' script when calling the doctor: 'This is a change from baseline, and I'm worried about an infection.'
  • You don't need expensive tools—a notebook, a pen, and a recent photo are enough.

Why a Baseline Matters More Than a Single Snapshot

Without a baseline, every moment looks like it could be the new normal—or a crisis. As Teepa Snow explains, if you don't measure how often, how intense, or how long something lasts, you might not notice a 50% change because it feels the same as before. A baseline is simply a record of what is typical for your person: how they sleep, eat, move, communicate, and handle daily tasks. Once you have that, you can compare later observations and see if something is truly different or just a variation within their usual pattern.

The Danger of 'Diagnostic Overshadowing'

A common trap is blaming every new symptom on dementia itself. As Dementia Careblazers point out, healthcare providers may dismiss a sudden change as 'just the disease,' leaving you feeling confused and guilty. But a sudden change from a well-documented baseline—like new confusion, a fall, or a change in appetite—could signal an infection, medication side effect, or another medical issue. Your instincts matter, and having a baseline gives you the language to say, 'This is a sudden change from baseline, and I'm concerned something medical is happening.'

What to Track: The Core Domains

Focus on a few key areas that are easy to observe without being intrusive. Dr. Camille Sinclair recommends tracking functional decline: can they still prep meals, dress themselves, or use the bathroom safely? Also note changes in mood (more anxious or withdrawn), sleep patterns (up at night, napping more), eating habits (weight loss, forgetting to eat), and communication (fewer words, trouble finding names). The goal is not to create a medical chart but to have a simple record—bullet points in a notebook or a note on your phone—that you can share with their care team.

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

Step-by-step

  1. Start a simple log today. Use a small notebook, a notes app on your phone, or a calendar. Each day, write one or two sentences about how your loved one seemed: 'Ate half their breakfast, seemed tired, walked with a shuffle.' Do this for at least three to seven days to establish a rough baseline.

  2. Pick three to five specific things to watch. For example: how much they eat at meals, how many times they get up at night, how many words they speak in a conversation, whether they need help with the toilet, and their general mood (calm, irritable, withdrawn). Write these down once a day at the same time, like after dinner.

  3. Take a recent photo of your loved one's face and full body. As the Dementia Caregivers Academy advises, faces change with age, so a picture from five years ago won't help. Keep this photo on your phone to compare if you notice swelling, paleness, or a new look that might signal illness.

  4. Create a 'phone chain' of two to three people who can help if you live far away or need backup. Write down their names and numbers. If you notice a sudden change, you can call them to come check or to help you decide if you need to call the doctor.

  5. Once a week, do a quick 'frailty check' using the Clinical Frailty Scale (available online). Rate your loved one from 1 (very fit) to 9 (terminally ill) based on their energy, mobility, and independence. This gives you a number you can track over weeks and months.

  6. If you notice a sudden change—like new confusion, a fall, not eating for a day, or a big mood shift—write down exactly when it started, what you saw, and what was different from the baseline. Then call their primary care provider and say, 'I have a baseline record, and this is a sudden change. I'm worried about an infection or another medical issue.'

  7. Use technology if it helps. Some families use motion sensors or simple apps that track movement and sleep patterns. As StackCare describes, after a few days these systems establish a baseline and alert you if someone hasn't gotten up by their usual time or is using the bathroom excessively. This can be especially helpful if you don't live with your loved one.

  8. Review your log every two weeks. Look for patterns: are they sleeping more? Eating less? More irritable in the afternoons? These slow trends are just as important as sudden changes. Share your observations with the doctor at every visit, even if nothing seems urgent.

What not to do

  • Don't rely on memory alone. You might think, 'They seem worse,' but without notes, you can't say how much. Write it down, even if it's just a few words. Memory is unreliable, especially under stress.

  • Don't wait until you're sure something is wrong. If you notice a change, document it and mention it to the care team. As Dr. Allyson Palmer says, caregivers notice subtle changes that physicians might miss. Early reporting can prevent a crisis.

  • Don't compare your loved one to how they were years ago. Their baseline is now, not five years ago. A person who was once a marathon runner may now walk slowly—that's their new normal. Track from where they are today.

  • Don't blame every change on dementia. A sudden decline in cognition or behavior could be a urinary tract infection, dehydration, a medication side effect, or even pain. Always consider other causes first, especially if the change is sudden.

  • Don't overwhelm yourself with tracking everything. Pick a few key areas and stick with them. Too much data can be confusing and stressful. Simplicity is your friend.

  • Don't keep your observations to yourself. Share them with the doctor, the home health aide, or a trusted family member. A second set of eyes can help you see patterns you missed.

Practical tools

  • The One-Sentence Daily Log

    Each evening, write one sentence about how your loved one was today. Example: 'Ate well, walked to the mailbox, seemed happy.' Or: 'Refused lunch, slept most of the day, seemed confused about where he was.' This takes 30 seconds and gives you a powerful record.

  • The 'Sudden Change' Script

    When you call the doctor, say: 'I have been tracking my loved one's baseline. This is a sudden change from that baseline. I'm concerned there may be an underlying medical issue like an infection. Can we get them seen today?' This phrase is direct and respectful, and it signals that you are an informed observer.

  • The Frailty Scale Card

    Print or save the Clinical Frailty Scale (9-point scale). Once a week, rate your loved one. Write the number and date. Over months, you'll see if they are slowly declining or stable. This is a simple, validated tool used by healthcare professionals.

  • The Photo Check-In

    Take a new photo of your loved one's face and full body every month. Store it in a folder on your phone. If you notice a change in skin color, swelling, or weight loss, you can compare it to the most recent photo and show the doctor.

  • The Motion Sensor or App (if accessible)

    Consider a simple motion sensor system like StackCare or a similar app that tracks movement and sleep. After a few days, it establishes a baseline and alerts you to unusual patterns. This is especially useful if you don't live with your loved one or if they live alone.

  • The Phone Chain List

    Write down the names and phone numbers of two to three people who can help in an emergency. Keep it on your fridge or in your wallet. If you notice a sudden change, call the first person on the list to come check or to help you decide next steps.

Discuss with your clinician

Ask your doctor: 'What specific changes should I track for my loved one's type of dementia? Are there any red flags I should call you about immediately?'

Ask: 'If I notice a sudden change in cognition or behavior, how quickly should I bring them in? Should I go to the ER or call your office first?'

Ask: 'Are there any medications or supplements that could cause sudden changes in my loved one's baseline? Should I watch for any side effects?'

Ask: 'What is the best way to share my tracking log with you? Should I bring it to appointments or email it beforehand?'

Ask: 'If my loved one has a sudden change and I suspect an infection, what tests should I request (e.g., urine culture, blood work)?'
