How to divide dementia-care responsibilities among siblings
Sibling tension during dementia care is extremely common, and it is usually misdiagnosed. It looks like a disagreement about values. It is more often the absence of an explicit agreement about work.
Once responsibilities are written down and assigned, a substantial share of the friction resolves without anyone changing their personality.
Write down everything that is currently happening
Before discussing fairness, make the work visible. List every recurring task: appointments, medication management, bill payment, insurance calls, groceries, laundry, home maintenance, emotional support, and daily check-ins.
Families are routinely surprised by the length of this list, and the primary caregiver is often surprised that anyone finally sees it.
Assign categories, with a named owner
Each category gets exactly one owner who is accountable for it, even if others help. Shared ownership without a named owner reliably produces gaps.
Distance is not an exemption. Finances, insurance calls, appointment scheduling, research, and paperwork can be handled entirely remotely, and doing so meaningfully reduces the local caregiver's load.
Money is part of the conversation
Where one sibling contributes substantially more time, it is reasonable to discuss whether others contribute financially, including toward respite care or paid help.
Have this conversation explicitly and early. Unspoken expectations about money are a frequent source of long-term resentment.
Agree on how decisions get made
Decide in advance who decides. Often it is the person with health care power of attorney, informed by input from the others. Without that agreement, every decision reopens the same argument.
Set a recurring check-in — monthly is usually enough — so adjustments happen on a schedule rather than during a crisis.
When agreement is not possible
Some families cannot reach consensus, particularly where longstanding conflict predates the diagnosis. In those situations, a neutral facilitated conversation, a family therapist, or an eldercare mediator can help.
The realistic goal is often a workable arrangement rather than genuine agreement.
