The 10 Early Warning Signs of Dementia
Dementia rarely arrives suddenly. It usually begins with subtle changes that families notice before the person does. Recognising these early signs — especially when several appear together and are getting worse over months — is the first step towards a diagnosis that can genuinely help. Here are the ten to watch for.
1. Memory loss that affects daily life
Forgetting recently learnt information, important dates or events, asking the same questions repeatedly, and relying more and more on reminders or family to manage things that used to be easy.
2. Difficulty with familiar tasks
Struggling with routines the person has done for years — cooking a familiar dish, operating the geyser or TV remote, managing money or bills, or finding the way to a well-known place.
3. Language and word-finding problems
Trouble following or joining a conversation, stopping mid-sentence, or reaching for the wrong word — for example, calling a watch a "hand-clock". Beyond the normal occasional lapse.
4. Disorientation to time and place
Losing track of the date, season or the passage of time, or becoming confused about where they are and how they got there.
5. Poor judgement
Making uncharacteristically poor decisions — with money, giving away large sums, falling for scams, or neglecting personal hygiene and safety.
6. Misplacing things
Putting objects in unusual places (keys in the fridge), losing things and being unable to retrace steps, sometimes accusing others of stealing.
7. Changes in mood and personality
Becoming unusually anxious, suspicious, irritable, low or fearful, or behaving out of character.
8. Withdrawal from work and social life
Stepping back from hobbies, social gatherings, religious or community activities they once enjoyed, often to hide difficulties.
9. Problems with visual and spatial tasks
Difficulty judging distance, reading, recognising faces, or navigating stairs — sometimes affecting driving.
10. Difficulty planning and problem-solving
Trouble following a plan, working with numbers, or concentrating on multi-step tasks, taking far longer than before.
Distinguishing Normal Ageing From Dementia
Everyone becomes a little more forgetful with age, and worrying about every lapse causes needless distress. The key question is whether the changes interfere with everyday life and are getting steadily worse — that is what separates ordinary ageing from dementia.
With normal ageing, you might forget a name or where you put your glasses, but it comes back to you later, and you still manage your daily affairs. You may search for a word occasionally, take a little longer to learn something new, or forget which day it is but work it out quickly. Insight is preserved — you know you are forgetful and can compensate.
With dementia, the person forgets the entire event, not just a detail, and does not recall it even when reminded. They repeat the same question minutes apart, get lost in familiar places, struggle with tasks they have done for decades, and — crucially — often lose awareness that anything is wrong, so it is family who notice. A single forgetful moment is not dementia; a pattern of decline that disrupts independence and worsens over months is what warrants assessment.
What to Do If You're Concerned About a Parent
If you have noticed several of these signs in a parent, the natural instinct is either to panic or to explain it away as "just old age". Neither helps. The calm, practical middle path is to observe, note and seek assessment.
Start by keeping a simple record over a few weeks — what you have noticed, when it started, whether it is getting worse, and how it affects daily life. Concrete examples ("forgot to switch off the gas twice this month", "could not find the way home from the market") are far more useful to a doctor than a vague "memory is bad". Gently check practical safety: medicines being taken correctly, finances, cooking and, if relevant, driving.
Approach the conversation with kindness, not confrontation. Many older adults fear the loss of independence and may resist, so framing it as a routine "check-up for memory and general health" is often gentler than announcing a suspicion of dementia. Involving a trusted family member or the family doctor can help. The goal is to get a proper assessment — not to prove a point — because some causes are reversible, and even when they are not, early support makes life better for everyone.
When to Seek Assessment
It is worth seeing a neurologist when memory or thinking changes are persistent, worsening, and affecting daily life — rather than the occasional lapse everyone has. You do not need to wait for things to become severe; in fact, earlier is far better.
Seek assessment sooner if you notice: repeated forgetting of recent events or conversations; getting lost in familiar surroundings; difficulty managing money, medicines or familiar tasks; new confusion, suspiciousness or personality change; word-finding trouble that disrupts conversation; or several of the ten warning signs together. A sudden or step-wise decline, especially after suspected strokes, also needs prompt review.
There is a real advantage to acting early. Some causes of memory loss — thyroid disease, vitamin B12 deficiency, depression, medication effects — are fully reversible if caught, and would be tragic to miss. And where the cause is a progressive dementia such as Alzheimer's, starting treatment early, planning ahead and putting support in place all give the best possible quality of life. There is no benefit in waiting.
What the Assessment Involves at Gini
Families are often anxious about what a memory assessment involves, imagining something frightening or invasive. In reality it is thorough but gentle, and it is built around finding a cause rather than simply confirming a fear.
Dr. Iqbal Singh begins with a careful history, usually asking both the patient and a family member about what has changed, when it started, and how it affects daily life. This is followed by a physical and neurological examination, and short structured cognitive tests — most often the MMSE and MoCA — which measure memory, attention, language and other thinking skills in about ten to fifteen minutes.
Crucially, the assessment includes a search for reversible causes: blood tests for thyroid function, vitamin B12, blood sugar, kidney and liver function, and a review of all current medications. A brain scan (CT or MRI) is often arranged to look for strokes, bleeding, tumours or hydrocephalus, and to assess the pattern of any shrinkage. Because Gini brings neurology together with diabetes and cardiology care, the vascular risk factors that damage the brain can be addressed at the same time.

How Early Diagnosis Helps
Some families hesitate, wondering whether a diagnosis changes anything if there is "no cure". In truth, early diagnosis helps in several concrete and important ways, and the benefits are real regardless of the cause.
First, it finds the reversible causes — the treatable thyroid, B12, depression and medication problems that can be corrected, sometimes restoring thinking completely. Second, where the cause is Alzheimer's or another degenerative dementia, starting treatment early tends to work better, helping preserve memory and function for longer. Third, it allows the family to control the vascular risks — blood pressure, diabetes, cholesterol — that otherwise accelerate every kind of decline.
Beyond medicine, an early diagnosis gives the family time to plan and prepare — to organise finances and legal matters, make the home safe, arrange support, and have important conversations while the person can still take part in decisions about their own care. It also brings relief: understanding what is happening reduces the fear, blame and conflict that uncertainty causes. Above all, it opens the door to ongoing support.
