We talk a lot about cycles in dementia. The diagnostic cycle. The grief cycle. The cycle of good days and bad ones. But there's one that is so prevalent across the world with family carers that I haven't heard anyone in positions of power yell about — the Exhaustion Cycle.

I came across it this week in the most personal way possible. I'm ill. Nothing major, just a cold. But it was while sitting half-medicated, answering messages on the Dementia Life Instagram page, that the injustice of it crystallised for me.

What the Exhaustion Cycle Actually Looks Like

It starts with exhaustion. Real, bone-deep exhaustion. Not the kind that goes away after a decent night's kip. This is the kind that accumulates slowly over months, because you never fully switch off. Your brain is always on. Half-listening, even when nothing is happening. Tracking.

That kind of exhaustion wears you down physically. It means your immune system isn't working the way it should. And so you pick things up. Colds. Bugs. Whatever's going round.

And then you get ill.

And you can't rest.

Because the caring doesn't stop because you have a temperature. The medication still needs giving. The meals still need making. The questions still need answering — quite possibly the same question that you answered twenty minutes ago and twenty minutes before that. You don't get sick days. There's no one to fuss over you with a hot drink while you lie on the sofa.

So you push through. And the cold that should have been three days becomes ten. And by the time it clears, you're more depleted than before. And the cycle starts again.

The Hierarchy of the Exhaustion Cycle

I'm in a more fortunate position than most. After a day with my mum, working from my parents' dining room, I can go home. Home to my own space, my fiancée and pets. That line between carer and not-carer — however blurry — exists for me.

But it doesn't exist for everyone. For live-in carers, for spouses, for partners who sleep in the same bed as someone with dementia and spend the night listening for movements in the dark — the Exhaustion Cycle hits differently. There's no clocking off. There's no walk home to reset. It just continues, into the evening, into the night.

I think about those people a lot.

Why Nobody Talks About the Physical Cost

The physical toll of caring for someone with dementia doesn't get talked about enough. We've made progress on the conversation around the emotional impact — the grief, the loneliness, the invisible labour of it. But the physical cost of never stopping? Of running on fumes for months, for years, because someone you love needs you to? That's still largely unseen.

The NHS doesn't have a pathway for it. Your GP doesn't have a referral for it. Nobody sends you home with a leaflet that says:

"By the way, long-term unpaid caring will compromise your immune system, your sleep, and your blood pressure, and we have absolutely nothing in place to help with that."

It just happens. Quietly. Invisibly.

You get run down, you get ill, you get up and do it again.

The Exhaustion Cycle Needs to Be Part of the Conversation

At Dementia Life, we're committed to changing this. The Family Impact Study is gathering the evidence — documenting the physical and emotional toll that dementia places on families, friends, and carers across the UK. Because until that evidence exists in a form that policymakers can't ignore, nothing will change.

If you're in the Exhaustion Cycle right now, I want you to know this: what you're experiencing is real, it's measurable, and it matters. You are not making it up. You are not weak. You are running a marathon that nobody entered you into, and you're doing it without a support team.

We see you. Dementia Life is here to support you. Our Online Meetings give you the chance to have genuine, open and frank conversations with others that know the exhaustion cycle and make you feel less alone
