We’ve all had those moments: you walk into a room and can’t remember why, you misplace your keys for the third time this week, or you blank on a familiar name at a family gathering.
For many Australians over 50, these little lapses can spark a nagging worry: is this just normal forgetfulness, or could it be something more serious, like dementia?
We know how important it is to separate fact from fear. So, we’ve gathered expert advice and practical tips to help you understand what’s normal, what’s not, and when it’s time to seek help.
First, let’s put your mind at ease: some memory slip-ups are a completely normal part of getting older. According to Professor Kaarin Anstey, director of the UNSW Ageing Futures Institute, it’s common for our brains to slow down a little as we age.
You might find yourself searching for a word that’s ‘on the tip of your tongue’ or occasionally misplacing your phone or glasses. These are classic signs of normal ageing, not dementia.
Professor Amy Brodtmann, neurologist and head of the Cognitive Health Initiative at Monash University, adds that it’s also normal to feel like you’re not as quick as you used to be.
‘Our processing speed can slow with age, which can be frustrating, especially for people who are used to juggling multiple tasks,’ she says. If you start six things and only finish five, you’re in good company!
Occasional forgetfulness is a normal part of ageing, but certain patterns can signal potential dementia or other cognitive issues. Experts recommend paying attention to specific signs. For instance, frequent or severe memory lapses can be cause for concern.
Forgetting where you left your keys from time to time is normal, but regularly misplacing items, finding them in odd places (such as the fridge), or being unable to recall how they ended up there may indicate a problem. More severe lapses, such as leaving the stove on or forgetting to turn off the tap, are also warning signs.
Language difficulties are another red flag. It’s common to occasionally mix up your children’s or grandchildren’s names, but having trouble finding words, stumbling through sentences, or speaking in a disjointed manner (‘word salad’) can be concerning. Consistently forgetting the names of close family members is also a signal.
Getting lost in familiar places is another sign to watch for. While it’s typical to get lost in an unfamiliar neighbourhood, becoming disoriented or lost in known areas, such as your local shops or even your own street, should not be ignored.
Forgetting important, recent events, like the passing of a close friend or a major family event, is another concerning symptom.
Repeating yourself is also common, like telling a favourite story over time. However, if you find yourself repeating the same story or question within a single conversation or forgetting you’ve already shared it, it could be a cause for concern.
Finally, lapses in attention, such as walking into a room and forgetting why, can occur due to distraction, but if this happens frequently and is accompanied by other symptoms, it may be worth investigating further.
Not all memory problems are linked to dementia. Many other factors can affect your memory. Fatigue, such as from poor sleep or general exhaustion, can make anyone more forgetful.
Chronic stress is another common culprit, often interfering with short-term memory. Certain medications—including some painkillers, sleep aids, and even treatments like chemotherapy—may also lead to what’s commonly called ‘brain fog’.
Illnesses, particularly those involving post-viral fatigue, such as after a COVID-19 infection, can similarly impact cognitive clarity and memory function.
If you’ve always been a bit absent-minded, don’t panic—this doesn’t mean you’re at higher risk of dementia. However, it can make it harder to spot changes if they do occur.
The good news? Many of these risk factors are within your control. Staying active, eating well, keeping your mind engaged, and maintaining social connections can all help protect your brain.
If you or your loved ones notice changes in your memory or thinking—especially if they’re getting worse or interfering with daily life—it’s time to talk to your GP. Early assessment is key. Only about one in 10 people with mild cognitive impairment will go on to develop dementia, and early intervention can make a big difference.
Your GP may refer you to a geriatrician or a memory clinic for further testing. Don’t be afraid to seek help—even if you think it’s ‘just ageing.’ It’s always better to be safe and get it checked.
