Early Signs of Dementia: How to Tell It From Normal Ageing

Noticing that a parent is repeating the same question, getting lost on a familiar route or struggling with something they have done for years can be unsettling. This guide explains the common dementia signs and symptoms described by Singapore’s health authorities, how they differ from the ordinary forgetfulness that comes with age, and what to do next if you are worried, including how to get an assessment and where to find support.

Most families we speak with have been noticing small things for months before they say anything. Part of that is kindness: nobody wants to suggest something is wrong with a parent. Part of it is uncertainty, because everybody forgets things, and it is hard to know when forgetfulness becomes something more.

We rely here on HealthHub, the Agency for Integrated Care (AIC) and Dementia Singapore. This article is general information, not a diagnosis. Only a doctor can assess whether changes are caused by dementia or by something else, and some of those other causes are treatable.

Dementia is not a normal part of ageing

HealthHub is clear on this point: dementia is an illness, not a normal part of ageing. Many people live into their eighties and nineties with sharp minds and only the occasional lapse. When thinking and memory changes start to get in the way of everyday life, that is a reason to see a doctor, not something to accept as “just old age”.

This matters because families sometimes wait. They assume the changes are inevitable, so there is no point in raising them. In reality, HealthHub notes that early treatment has many benefits for patients and their families, and that some conditions which look like dementia can be treated.

Normal forgetfulness or something more?

HealthHub’s article When Memories Fade explains the key difference. Ordinary forgetfulness usually happens when someone is distracted or doing several things at once, and given time, the person remembers. With dementia, the lapses in memory and behaviour are abnormal and persist even with prompting or extra time.

A practical way to think about it:

• Usually part of normal ageing: forgetting a name and recalling it later, occasionally misplacing keys, feeling sad or moody from time to time, slight personality changes over the years. The person still manages daily life independently.
• Worth raising with a doctor: forgetting recent events entirely, asking the same question again and again, getting lost somewhere familiar, struggling with a task they have done for years, or changes in mood and personality that are sudden or out of character.

A useful question for families is whether the changes are starting to affect your parent’s ability to live safely and independently, and whether they seem to be getting worse over time. Either way, only a doctor’s assessment can tell the difference.

Common dementia signs and symptoms to look out for

HealthHub lists ten warning signs. Not everyone will show all of them, and having one does not mean a person has dementia. A pattern that keeps appearing, or gets worse, is what to watch for.

1. Memory loss that affects day-to-day life. Forgetting recent events, conversations or meals, and repeating questions because the answer has been forgotten.
2. Difficulty doing familiar tasks. Struggling to cook a dish they have made for decades, or to follow the steps of a routine chore.
3. Confusion about time and place. Getting lost in a familiar neighbourhood or not knowing what day it is.
4. Problems communicating. Difficulty finding words or following a conversation.
5. Difficulty planning or solving problems. Trouble with bills, household budgets or following a plan.
6. Poor or decreased judgement. Unusual decisions about money, such as giving large amounts to strangers.
7. Misplacing things. Losing items often, or putting them in unusual places.
8. Changes in mood or behaviour. Rapid mood swings without an obvious reason.
9. Changes in personality. Becoming suspicious, fearful or withdrawn in a way that is out of character.
10. Withdrawal from work or social activities. Losing interest in friends, hobbies or community activities they used to enjoy.

AIC’s page on signs and symptoms of dementia adds practical examples: difficulty with daily activities such as dressing or bathing, becoming easily upset or frustrated, and getting disoriented while walking or driving.

Early signs of dementia are easy to miss

In the early stages, people often cover for small lapses, and family members fill the gaps without realising it. A spouse takes over the bills. A child starts reminding them about appointments. A helper notices that a dish tastes different or that the stove was left on. Because these changes happen gradually, it can help to step back and ask: compared with a year ago, what is different?

What you can do if you notice these signs

1. Keep simple notes

Before the doctor’s visit, write down what you have noticed, roughly when it started and how often it happens. Specific examples are far more useful than general impressions. “She asked three times this morning whether we had eaten” tells a doctor more than “her memory is bad”. If a helper lives with your parent, ask her what she has noticed too, as she may see patterns during the day that the family misses.

2. Talk to your parent gently

Choose a calm moment and focus on wellbeing rather than memory. Framing it as a general health check, or as something to rule out, often feels less threatening. Avoid testing or correcting them in front of others.

3. See a doctor

A family doctor or polyclinic is a sensible first step. HealthHub advises that if you notice these signs regularly, you can consult a memory clinic at a hospital. AIC also suggests that families may approach a community mental health team for screening, intervention and caregiver support.

Getting assessed: what to expect

According to HealthHub, telling normal forgetfulness apart from dementia takes a thorough assessment by a doctor, and sometimes a psychologist. The process may include:

• A medical history and examination, including questions for family members about the changes they have seen.
• Blood tests to check for underlying conditions or other abnormalities.
• Brain imaging to look for structural changes, such as those caused by a stroke or tumour.
• Questions from a psychologist that test different aspects of thinking and memory.

Other conditions can look like dementia

This is one of the most important reasons not to wait. AIC notes that other medical conditions, such as vitamin B12 deficiency or infections, can cause dementia-like symptoms. HealthHub adds that depression and hormone disorders can cause similar signs and are treatable. A proper assessment helps find the cause.

Dementia usually develops gradually. If someone becomes suddenly and severely confused or unwell, treat it as an emergency and call 995.

Support for families after a diagnosis

A diagnosis is hard news, but it also opens the door to help. There is no cure for dementia, but HealthHub notes that some medicines prescribed by a doctor may help maintain memory, thinking and speaking skills, alongside therapies such as music, art and reminiscence therapy. Planning early also gives the person a chance to share their wishes.

• AIC runs a hotline at 1800 650 6060 and can point you to services in your area.
• Dementia Singapore runs a Dementia Helpline on 6377 0700 for advice and support.
• Community activities help keep older adults socially connected. Our guide to Active Ageing Centres in Singapore explains what they offer.
• Financial support may be available. Our guide to the Home Caregiving Grant explains who qualifies.

As needs grow, many families look at help at home. A trained, patient helper can support routines, safety and companionship, and our guide to daily dementia care routines for helpers shows what that looks like. If you are considering it, our page on helpers with elderly caregiving experience explains how we match families.

Looking after yourself as a caregiver

Families often put their own wellbeing last. Watching a parent change is emotionally tiring, and caregiving can stretch over many years. Share the load early with siblings, ask for help before you reach breaking point, and connect with support groups where other caregivers understand what you are going through. HealthHub points caregivers to respite care and day centres, which provide breaks and support.

Frequently Asked Questions

What are the first signs of dementia?

Early signs often include forgetting recent events or conversations, repeating the same questions, difficulty with familiar tasks, trouble finding words, and getting lost in familiar places. Changes in mood, personality or interest in social activities can also appear early. HealthHub lists ten warning signs in total. One isolated lapse is not a cause for alarm, but a pattern that persists or worsens should be checked by a doctor.

How can I tell normal forgetfulness from dementia?

According to HealthHub, ordinary forgetfulness usually happens when someone is distracted or multitasking, and the person recalls the information later. With dementia, memory and behaviour lapses persist even with prompting or extra time. Changes that start to affect daily life are a reason to see a doctor. A thorough assessment by a doctor is the only reliable way to tell the difference.

Where can I get my parent assessed for dementia in Singapore?

Start with your family doctor or a polyclinic, who can refer you onwards. HealthHub suggests that people who notice warning signs regularly can consult a memory clinic at a hospital. AIC also notes that families can approach a community mental health team for screening and caregiver support, and its hotline on 1800 650 6060 can help you find services near you.

Can dementia-like symptoms be caused by something treatable?

Yes. AIC notes that conditions such as vitamin B12 deficiency or infections can cause dementia-like symptoms, and HealthHub adds that depression and hormone disorders can cause similar signs. These conditions are treatable, which is why it is important to get symptoms checked by a doctor rather than assume they are due to dementia or ageing.

Is there a helpline for families worried about dementia?

Yes. Dementia Singapore runs a Dementia Helpline on 6377 0700, and the Agency for Integrated Care has a hotline on 1800 650 6060. Both can help families understand next steps and find support services. If someone becomes suddenly and severely confused or unwell, call 995 immediately.

Conclusion

Dementia signs and symptoms rarely arrive all at once. They tend to show up as small, persistent changes in memory, judgement, mood and the ability to manage everyday life. The difference between normal ageing and dementia is not whether someone forgets, but whether the forgetting gets in the way of living safely and independently, and whether it is getting worse.

If you are worried, write down what you have noticed and book a doctor’s appointment. An assessment may find a treatable cause, and if it is dementia, an early diagnosis gives your family time to plan and to put support in place.
