There are four cycles we talk about at Dementia Life. The Diagnostic Cycle. The Exhaustion Cycle. The Grief Cycle. And this one — the one that, in some ways, is the most quietly cruel.

The Good Day/Bad Day Cycle.

It sounds straightforward enough. Dementia fluctuates. Some days are better than others. Most people who've heard anything about dementia understand this much.

What they don't tell you is what good days do to you.

What a Good Day Actually Looks Like

A good day is not a cure. It is not a reversal. It is a window — sometimes an hour, sometimes a whole afternoon — where the person you love is more fully present than usual. Where the words come more easily. Where there's a joke, or a memory, or a moment of connection that feels completely real and completely them.

Recently, my mum laughed. Properly, unselfconsciously laughed, at something on the television. I can't tell you exactly what it was that hit me in that moment — partly joy, partly something harder to name.

A good day is a gift. That part is genuinely true. But a good day is also a reset.

Why Good Days Make the Bad Days Harder

When you've had a good day — or a run of good days — your nervous system recalibrates. Quietly, without you deciding to, your baseline shifts upward. You start moving through the world at a slightly higher level of hope.

And then the next bad day comes.

A bad day after a run of good ones lands harder than a bad day after a run of bad ones. Because you've been reminded, viscerally, of what is possible. And then it's taken back.

This is the mechanism of the Good Days/Bad Days Cycle. It is not a steady decline. It is a series of ascents and drops. And every ascent recalibrates you. And every drop resets you lower.

The Problem of Good Days With Other People

There's a particular complication that many dementia carers will recognise. A family member visits — someone who doesn't see your loved one every day — and they catch a good day. A really good day. And they come away from it thinking: they seemed fine to me.

And you don't know whether to laugh or cry.

Because fine is a snapshot. Fine is one afternoon. Fine is not the Tuesday morning two weeks ago when everything was very different.

Good days can, without anyone meaning any harm, create a distorted picture of what daily life actually looks like. And that distorted picture — the 'they seemed fine when I saw them' version — is one of the most isolating experiences in dementia caring.

The Joy That Hurts

I want to say something carefully here, because I don't want to sound like I'm arguing against good days. I'm not. I would not trade a single one.

But I think there's something important in naming the fact that joy in dementia caring is often complicated. It is real joy. And it co-exists with something else — something that is hard to describe to someone who hasn't experienced it.

When my mum has a good day, I feel it completely. And at the same time, there is a part of my brain that is noting it, filing it, knowing that this is not a trajectory but a moment. And that part is where the grief lives. Quietly, alongside the joy.

Riding the Cycle

There is no way to opt out of the Good Day/Bad Day Cycle. It is the nature of dementia. What you can do — and this is easier said than done, I know — is resist the urge to interpret either extreme as the whole picture.

A very bad day is not the end. A very good day is not a sign that things are improving.

Both are true. Both are real. Both deserve to be felt fully, without too much weight being placed on either.

And when you're in the middle of it — when you're recalibrating again after another drop — I want you to know that we see the cycle you're on. We understand the cost of it.

If you want to talk about the never-ending exhaustion of cycling through good days, bad days and all the days in between our Online Meetings are here for you. Talk to others who know what you're going through and can properly understand.
