There are certain moments in life that stay with you forever. One of mine was realising that something was changing in someone I loved.
At first it did not seem significant. A forgotten appointment here. A repeated story there. A misplaced purse that eventually turned up in an unusual place. Like many families, I brushed these incidents aside. We all forget things from time to time. Life is busy. Stress affects memory. Growing older brings changes.
Yet there came a point when the little things no longer felt quite so little.
Dementia rarely arrives dramatically. More often it slips quietly into everyday life. The earliest signs can be subtle, confusing and easy to explain away. Family members may not recognise what they are seeing because the changes happen gradually.
One of the reasons dementia is often diagnosed later than it should be, is that many of the early symptoms do not look like memory problems at all.
If you are worried about a parent, spouse, relative or close friend, understanding the warning signs can help you seek support sooner and plan for the future with greater confidence.
Why early recognition matters
A diagnosis does not change who a person is. What it can do is provide answers.
Recognising potential symptoms early allows families to access medical assessments, support services, treatment options and practical guidance. It also gives the person experiencing symptoms the opportunity to participate in important decisions about their future.
Many conditions can mimic dementia including depression, thyroid disorders, medication side effects, infections, sleep disorders and vitamin deficiencies.
That is why seeking professional advice is always worthwhile when concerns arise as it may not be Dementia after all.
Memory loss that disrupts daily life
When most people think about dementia they immediately think about memory loss. Whilst occasional forgetfulness is a normal part of ageing, dementia-related memory problems tend to interfere with daily living. You might notice someone:
A person may genuinely have no recollection of asking the exact same question five minutes earlier. This differs from occasionally forgetting where you left your reading glasses or walking into a room and forgetting why you went there.
Difficulty managing familiar tasks
One of the earliest warning signs many families overlook is difficulty completing activities that were once routine. Tasks that have been performed successfully for years may suddenly become challenging.
Examples include:
Because these changes can happen gradually they are often attributed to stress, tiredness or simple distraction.
Problems finding the right words
Many people experience the occasional struggle to find a word. Dementia-related language difficulties tend to be more persistent.
Someone may:
My loved ones starting referring to things differently such as, the kettle became “that boiling thing” because the correct word would not come to mind. All animals, birds, insects and fish became “creatures”.
These language changes can create frustration and embarrassment which could lead some individuals to become quieter in social situations.
Confusion about time and place
Losing track of time occasionally happens to all of us. Dementia-related confusion is often more significant. You may notice someone:
One particularly concerning sign is becoming disoriented in places they have visited countless times before.
Poor judgement and decision-making
Changes in judgement can appear surprisingly early. Family members sometimes notice their loved ones making unusual decisions long before memory problems become obvious. Examples may include:
Sadly, older adults experiencing cognitive decline are often targeted by fraudsters. This is one reason families should pay close attention to significant changes in financial behaviour.
Misplacing items in unusual places
Most of us occasionally put something down and forget where we left it. Dementia often involves placing objects in unusual locations.
Examples include:
I once spent 3 hours looking for my step-father’s wallet for him because he refused to leave the house without it. I eventually found it inside a shoe in his wardrobe.
The issue is not simply losing the item. It is more the fact that the person will have no memory of placing it there, or why, and may become suspicious of others when it cannot be found.
Withdrawal from social activities
One symptom that often goes unnoticed is social withdrawal. Someone experiencing cognitive changes may start avoiding situations they once enjoyed. You may observe them:
This withdrawal may occur because they feel self-conscious about their difficulties and fear making mistakes in front of others. My mom began battling to keep score whilst playing tennis, a sport she played weekly for as long as I can remember. Slowly she started withdrawing from the club and making excuses why she couldn’t go that week.
Mood and personality changes
Dementia can affect emotions as well as memory. A person who has always been easy-going may become irritable, anxious or suspicious.
Common changes include:
Family members are often surprised by these shifts because they seem so different from the person’s usual temperament. Sometimes these emotional changes appear before noticeable memory problems.
Repeating stories and questions
Many families laugh off repeated stories. At first it may seem harmless but the concern arises when repetition becomes frequent and persistent. Someone may tell the same story several times within a short period without realising they have already shared it. Similarly, they may ask identical questions repeatedly despite receiving answers.
Whilst occasional repetition is normal, a consistent pattern deserves attention.
Difficulty following conversations
Following conversations requires memory, concentration and language skills. When cognitive changes develop, conversations can become increasingly challenging. A person may:
Large family gatherings can become particularly overwhelming. As a result, some people begin avoiding them altogether.
Increased reliance on family members
One subtle sign families often miss is increasing dependence.
A previously independent person may begin relying heavily on others for tasks they once handled confidently. You might find yourself helping with:
Because families naturally help one another, this gradual increase in support may not immediately raise concerns.
Changes in driving ability
Driving requires attention, judgement, memory and quick decision-making. Early warning signs may include:
These changes should never be ignored as they can affect both personal safety and the safety of others. I remember my step-dad all of a sudden not being able to switch the lights on and off in the car.
Neglecting household responsibilities
A once tidy home may begin showing signs of neglect. You may notice:
Sometimes these changes appear long before a diagnosis is considered. Family members often assume the person is simply tired or less motivated than before.
Sleep pattern changes
Research increasingly shows a connection between dementia and disrupted sleep. Early signs may include:
Whilst sleep disturbances can have many causes, significant changes warrant further investigation.
Losing interest in favourite hobbies
One particularly heartbreaking sign can be the gradual abandonment of activities that once brought joy.
A keen gardener may stop tending plants. An enthusiastic cook may lose interest in preparing meals. A passionate reader may struggle to finish books.
When a person begins walking away from long-loved hobbies, families should pay attention. My stepdad continued to buy countless books from the SPCA. He thrived on reading about history but he stopped actually reading the books. Gradually he would be seen flipping through pages to merely look at the pictures.
When should you seek medical advice?
Trust your instincts. Family members often notice changes long before a formal diagnosis is made.
If symptoms are becoming more frequent, affecting daily life, causing safety concerns, creating confusion, impacting finances or changing relationships, it is wise to arrange a medical assessment.
Even if dementia is not the cause, identifying underlying issues can significantly improve quality of life.
Supporting a loved one with compassion
Approaching someone about memory concerns requires sensitivity. Many people feel frightened, embarrassed or defensive so try to focus on observations rather than accusations.
Instead of saying:
“You have dementia.”
Consider saying:
“I’ve noticed you’ve seemed a little more forgetful lately and I’m wondering whether it might be worth speaking to your doctor.”
A gentle approach often leads to more productive conversations.
Looking beyond memory loss
One of the biggest misconceptions about dementia is that memory loss is always the first sign.
In reality, the earliest symptoms may involve judgement, personality, communication, organisation, confidence or emotional wellbeing.
Recognising these changes can help families seek support sooner. Awareness creates opportunities for assessment, planning and access to valuable resources. Most importantly, it allows families to approach the future with greater understanding and compassion.
If someone you love is showing several of these signs, know that you are not alone. Many families walk this path. Seeking answers is not about expecting the worst. It is about ensuring that the person you care about receives the support, dignity and guidance they deserve.
