Why They Seem 'Fine' With Others and Not With You: Understanding Showtime and Fluctuating Ability

You are not imagining things, and you are not being fooled. What you are witnessing is a real and common symptom of dementia called 'showtime' — a temporary ability to mask symptoms in certain situations or with certain people. This happens because the brain is working incredibly hard to use social reflexes and stored routines, but it comes at a huge cost: deep exhaustion afterward. Understanding this can protect your relationship and help you plan for more sustainable support.

Key points

  • Showtime is a real symptom, not manipulation. The person is not in control of it.
  • After showtime, expect a crash — exhaustion can last days. Plan for recovery.
  • Fluctuating ability (good days/bad days) is normal. Sudden, dramatic worsening may be delirium — get medical help.
  • You are not a fool. You are the person who sees the full picture. Trust your observations.
  • Use tools like a log, video evidence, and a recovery plan to advocate for your person and protect your own sanity.
  • Seek support from other caregivers — they will understand this experience immediately.

What Is Showtime?

Showtime is when a person with dementia appears to be 'normal' or much more capable in front of others — doctors, friends, family who visit rarely — but then struggles significantly when alone with you. This is not a deliberate act of deception. It is a brain-driven survival strategy. The person is drawing on deeply ingrained social reflexes and stored routines that are still intact, even as other cognitive functions decline. They are not thinking, 'I will put on a show.' Their brain is automatically adapting to the environment and the social cues present. This is why a person who cannot remember what they ate for breakfast can still carry on a polite conversation with a guest for 20 minutes.

Why Does It Happen?

The brain of a person with dementia is constantly trying to compensate for damage. In a familiar, safe environment with you, the brain can relax its guard — and that is when the real struggles emerge. With strangers or in novel settings, the brain activates a kind of emergency performance mode. This is fueled by adrenaline and intense concentration, but it is not sustainable. After the visitor leaves or the doctor's appointment ends, the person crashes. They may be exhausted for days, sometimes over a week. This is not a sign that they are 'faking' with you. It is a sign that they trust you enough to let their guard down, and that they have spent all their energy pretending to be okay for others.

The Role of Fluctuating Ability and Delirium

Dementia itself is not a steady decline. People have good days and bad days, good hours and bad hours. This is called fluctuating ability. It is normal and expected. However, if you see a sudden, dramatic worsening over hours or a day or two — not the usual pattern — this could be delirium, a medical emergency often caused by infection (like a UTI), medication side effects, or dehydration. Delirium is different from dementia progression because it comes on fast and can be reversible if treated quickly. Always rule out delirium before assuming the dementia has simply progressed.

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

Step-by-step

  1. 1. Recognize and name the pattern: When you see your person act 'fine' with others, say to yourself, 'This is showtime. It is a real symptom, not a personal rejection.' This reframe protects you from feeling hurt or foolish.

  2. 2. After any social visit or appointment, plan for a recovery period: Expect that your person will need extra rest, quiet, and low stimulation for at least 24 to 48 hours. Cancel non-essential activities. Offer a calm, familiar routine with simple meals and no new demands.

  3. 3. When a visitor or professional says 'they seem fine,' gently educate: Say, 'I understand why you think that. Dementia is often invisible in short interactions. The real challenges show up over time and in familiar settings. I am glad they had a good moment, but please know that this is not the full picture.'

  4. 4. Keep a simple log of 'good days' and 'bad days': Note what happened before each — sleep, visitors, time of day, medications, meals. This helps you identify patterns and also gives you concrete data to share with the doctor when they ask, 'How are things going?'

  5. 5. Use the 'call out' technique for tasks: If your person struggles to find or recognize an object (like a pen or a cup), literally name it as you hand it over: 'Here is your pen.' Keep the environment uncluttered and predictable. This reduces the cognitive load and can help them perform better.

  6. 6. Protect your own credibility with professionals: Record a short video (with permission) of a typical difficult moment at home — confusion, repetition, or frustration. Show this to the doctor or care manager. It is far more persuasive than describing it.

  7. 7. When you feel like you are 'looking like a fool' to others, remind yourself: You are not the fool. You are the one who sees the full picture. The person with dementia is not being manipulative. Their brain is doing its best to cope. Your role is to be the steady witness and advocate.

What not to do

  • Do not accuse the person of 'faking it' or 'putting on a show' on purpose. This will cause shame and confusion. They cannot control this. Instead, say, 'I see you worked so hard to be with our guest. That must have been exhausting. Let's rest now.'

  • Do not try to 'prove' to others that the person has dementia by pushing them into a stressful test. This can cause agitation and a crisis of trust. Instead, let the person have their good moment, and then share your log or video later.

  • Do not assume that a good day means the dementia is 'not that bad.' Fluctuation is normal. A good day does not erase the struggles of the bad days. Plan for the worst, enjoy the best.

  • Do not isolate yourself out of embarrassment. Join a caregiver support group (online or in person). Other caregivers will immediately understand this experience and can offer practical tips and emotional validation.

  • Do not ignore a sudden, dramatic worsening that lasts more than a day. This could be delirium. Contact the doctor immediately and ask them to check for infection, medication changes, or dehydration.

Practical tools

  • The 'Showtime Recovery' Plan

    Create a simple written plan for after any visitor or appointment: 1) Quiet environment (dim lights, no TV), 2) Offer a familiar snack and drink, 3) Allow for a nap or rest without interruption, 4) Cancel any other plans for 24-48 hours. Post this where you can see it.

  • The 'One-Liner' for Skeptical Family

    When a relative says, 'But she seemed fine to me,' respond calmly: 'I am so glad she had a good moment with you. Dementia is tricky — it comes and goes. The real challenges show up in daily life, and I am the one who sees them. I appreciate your support.'

  • The 'Good Day/Bad Day' Log

    Keep a small notebook or a note on your phone. Each day, write one word: 'Good,' 'Fair,' or 'Bad.' Then note any possible triggers: 'Slept well,' 'Had a visitor,' 'New med,' 'Seemed restless.' Over two weeks, patterns will emerge that you can share with the doctor.

  • Video Evidence (with consent)

    If you are comfortable and it is legal in your area, record a short (30-second) video of a typical struggle at home — e.g., your person asking the same question repeatedly, or being unable to find a familiar object. Show this to the doctor or care manager. It is worth a thousand words.

  • Environmental Cues for Better Function

    Reduce clutter in the room where your person spends most time. Use labels on drawers and cupboards (e.g., 'Spoons,' 'Socks'). Keep a consistent routine for meals and sleep. Predictable environments reduce the need for the brain to 'perform' and can reduce showtime crashes.

Discuss with your clinician

If you notice a sudden, dramatic worsening over hours or a day or two, ask the doctor: 'Could this be delirium? Can we check for a urinary tract infection, medication side effects, or dehydration?'

If your person is prescribed any new medication, especially an antipsychotic, ask: 'Is this safe for someone with Lewy body dementia or other dementia? What are the risks of side effects?'

If the person has visual hallucinations that seem to distress them, ask: 'Could this be related to their dementia type? Are there non-medication strategies we can try first?'

If you are struggling with the emotional impact of showtime, ask your doctor or a social worker: 'Are there caregiver support groups or counseling services you can recommend?'
