Dementia: why do early planning and care matter?

What is dementia?

Dementia is a group of conditions in which brain deterioration affects memory, language, judgement, orientation and self-care. It is long-term and progressive, and is not an inevitable part of normal ageing. It is one of the common causes of mental incapacity in older people, gradually eroding a person's ability to handle financial and medical decisions on their own. This section is for general understanding only and cannot be used for self-diagnosis; whether someone has it, and how severe it is, must be assessed by a doctor.

• Common early signs include forgetting recent events, repeating questions, struggling with money or bills, and poorer orientation or judgement.
• It usually progresses over time, and the ability to handle complex matters (such as signing documents or managing finances) may be affected relatively early.
• An early assessment by a doctor helps the family use the window while capacity remains to complete planning.

This section is general health education, not a diagnosis or medical advice; if dementia is suspected, seek medical help early for a professional assessment.

Why plan early, while mental capacity remains?

Because several key legal documents require the person to still have 'mental capacity' at the time of signing. While cognition is still clear, arrange an enduring power of attorney (EPA) and advance directive (AMD) and a will early, so the person's wishes are fully recorded and can be carried out later; if you wait until cognition has clearly declined, it may no longer be possible to sign these documents validly, and the options narrow sharply.

• Enduring power of attorney (EPA): lets the person appoint an attorney in advance to manage financial matters if they later lose mental capacity; it must be signed while capacity remains and registered at the High Court of Hong Kong.
• Advance directive (AMD): expresses in advance the wish to accept or refuse life-sustaining treatment in specified circumstances.
• Will: sets out how the estate is distributed, reducing later disputes and delay.

This is an overview only; for each document's signing requirements, witnessing and registration, see the three essential end-of-life documents. This article is not legal advice; for formal arrangements, consult a solicitor and a doctor.

What happens if the EPA is not done in time?

If the person did not complete an enduring power of attorney before losing mental capacity, the family generally cannot use their bank deposits or deal with their property on their own, and must apply to the Guardianship Board (under the Mental Health Ordinance, Cap. 136) for a guardianship order. Compared with an EPA arranged in advance, the guardianship process is slower and the financial powers the guardian can exercise are limited, which may not flexibly meet every need. This is the difference between planning early and fixing it after the fact.

This is a general comparison, not legal advice; an EPA must be signed while capacity remains and registered at the High Court of Hong Kong, and a guardianship order's exact powers and process are subject to the Mental Health Ordinance (Cap. 136) and the latest rules of the Guardianship Board.

How can you plan early, step by step?

Use the window while capacity remains and work through it in order, dealing first with the documents that most need the person's own signature, then extending to care and financial arrangements. If you are unsure where to start, first see how we help to clarify priorities.

1. 1. Get a doctor's assessment earlyIf you notice changes in memory or judgement, seek a medical assessment early — both to intervene early and to confirm the person currently still has the capacity to sign documents.
2. 2. Complete the EPA and advance directiveWhile capacity remains, arrange an enduring power of attorney and advance directive with a solicitor and doctor, and complete the required witnessing and High Court registration.
3. 3. Make or update a willSet out how the estate is distributed and who the executor is, and review it alongside the EPA and advance directive so the documents do not contradict one another.
4. 4. Plan care and financial arrangementsAssess care needs and monthly costs, arrange the care model and financial safeguards, and discuss the division of duties with the main carer.

The steps are a general guide; the actual order and requirements vary from person to person, and each document's legal effect depends on proper signing and registration — consult a solicitor and a doctor.

What do care options and costs look like?

Care for dementia changes as the condition progresses, from home care and day centres to residential care, and costs vary widely and must be compared against the level of care and the family budget. This article does not repeat the details — read further: for the overall picture, see long-term care for older people; for home fees and how to choose, see how to choose a care home and understand the real cost; for the main carer's support and respite, see carer support. If caring at home, making good use of gerontech (such as anti-wandering aids and personal alarms) can also ease the strain of supervision.

• Home care: the person stays at home, supported by home-visit services, a day centre or safety technology, keeping a familiar environment.
• Residential care: worth considering when care needs are higher; compare the actual monthly cost of subsidised versus self-funded places.
• Carer support: the main carer's physical and emotional load matters — arrange respite and a division of duties early.

The eligibility, waiting times and fees of each service are subject to the latest announcements of the Social Welfare Department and individual providers; this section is general education, not personalised care advice.

How do you build a safety net for finances?

As cognition declines, the ability to manage money and resist scams may be affected relatively early, so setting up safeguards early is especially important. Beyond an EPA that lets an attorney manage finances under a clear authority later, you can discuss simplifying and consolidating accounts with family, setting up account alerts, and watching for suspicious transactions and sales pressure. Folding care costs into long-term cash flow, rather than scrambling for funds at the last minute, is what sustains care needs that may last for years.

• Arrange an enduring power of attorney early so that financial management has a clear authority later, reducing the risk of family being forced down the guardianship route.
• Simplify and consolidate bank accounts and keep a record of policies and an asset list, so an attorney or family can follow up later.
• Stay alert to scams and improper sales; where needed, set up transaction alerts or dual confirmation with family.
