Is It Normal Ageing or Something More?
Your mum forgot where she put her keys. She told you the same story twice in one phone call. She couldn't remember the name of that restaurant. Is this just getting older — or is it the beginning of dementia?
Almost 400,000 Australians live with dementia, with 1,800 new diagnoses every week. But not all memory changes are dementia. This guide helps you understand the difference, know when to see a GP, and learn how daily monitoring can detect subtle changes over time.
Normal Ageing vs Early Dementia
The key difference is not what they forget, but how it affects their life.
| Situation | Normal Ageing | Possible Cognitive Decline |
|---|---|---|
| Forgetting names | Forgets a name momentarily, remembers later | Doesn't recognise familiar people at all |
| Losing things | Misplaces keys, retraces steps to find them | Puts things in strange places (keys in fridge), can't retrace steps |
| Repeating stories | Tells the same story to different people | Tells the same story to the same person within minutes |
| Managing money | Occasionally forgets a bill | Can't understand bank statements, gives money to strangers |
| Cooking | Sometimes burns food or over-salts | Forgets they were cooking, leaves stove on repeatedly |
| Navigation | Takes a wrong turn on unfamiliar routes | Gets lost driving to familiar places (shops, church, GP) |
| Word finding | Tip-of-the-tongue moments | Uses wrong words or can't follow a conversation |
| Judgement | Makes a bad decision occasionally | Consistent poor judgement (inappropriate clothing, unsafe behaviour) |
| Mood changes | Occasional irritability or sadness | Personality changes — previously calm person becomes angry or suspicious |
| Daily routines | Needs a list for new tasks | Can't follow familiar routines (making tea, getting dressed in order) |
15-Point Family Assessment Checklist
Score each item: 0 = not present, 1 = sometimes, 2 = frequently. A total score of 10+ warrants a GP visit. This is not a diagnostic tool — it helps you prepare for a medical conversation.
Asks the same question or tells the same story repeatedly within one conversation
Forgets recent events (yesterday's visit, last night's dinner) but remembers the distant past clearly
Difficulty following the plot of a TV show or book
Gets confused about dates, seasons, or time of day
Trouble managing medications independently (skipping, doubling, wrong times)
Difficulty with familiar technology (remote control, phone, microwave)
Problems handling money — paying bills, making change, understanding statements
Personality changes — becoming suspicious, anxious, or unusually passive
Poor judgement in social situations or with personal safety
Declining personal hygiene (not showering, wearing same clothes for days)
Getting lost in familiar places or losing track of where they are
Difficulty planning or organising (cooking a meal with multiple steps)
Using the wrong word or struggling to follow conversations
Withdrawing from hobbies or social activities they used to enjoy
Changes in sleep patterns — sleeping much more or up at unusual hours
Scoring Guide
Likely normal ageing. Monitor but don't worry.
Worth discussing with GP. May be Mild Cognitive Impairment (MCI).
See GP urgently. Multiple areas of concern need assessment.
Reversible Causes That Mimic Dementia
Before assuming the worst, know that many conditions cause dementia-like symptoms and are treatable:
Depression
Often called "pseudodementia" — causes memory problems, confusion, and withdrawal that completely resolve with treatment.
Urinary Tract Infection (UTI)
In the elderly, UTIs frequently present as sudden confusion rather than urinary symptoms. Antibiotics resolve it within days.
Medication Side Effects
Anticholinergics, benzodiazepines, opioids, and some blood pressure medications cause cognitive impairment. Adjusting medications can restore function.
Vitamin B12 Deficiency
Common in over-65s (up to 20%). Causes memory loss, confusion, and balance problems. Blood test diagnosis, injection treatment.
Thyroid Disorders
Hypothyroidism causes cognitive slowing, fatigue, and memory problems. Simple blood test and medication treatment.
Dehydration
Chronic dehydration causes confusion, dizziness, and poor concentration. Common in elderly who don't feel thirsty.
Sleep Apnoea
Untreated sleep apnoea causes daytime cognitive impairment. CPAP treatment can significantly improve cognition.
Social Isolation
Prolonged isolation causes cognitive disuse — skills deteriorate without practice. Social engagement can reverse early decline.
What to Expect at the GP
Book a long appointment (double slot). Consider attending without your parent first to share your observations privately.
Cognitive Screening
Mini-Mental State Examination (MMSE) or Montreal Cognitive Assessment (MoCA). Takes 10–15 minutes. Tests memory, orientation, language, and executive function.
Blood Tests
Full blood count, thyroid function, vitamin B12, folate, glucose, kidney and liver function. Rules out reversible causes.
Medication Review
GP reviews all medications for cognitive side effects. May pause or swap medications and retest after 4–6 weeks.
Referral (if needed)
Geriatrician, neurologist, or memory clinic for formal assessment. Brain imaging (MRI or CT) may be ordered. Wait times vary by state.
Diagnosis & Planning
If Mild Cognitive Impairment (MCI) diagnosed: lifestyle modifications (exercise, social engagement, cognitive stimulation) can slow progression. If dementia: early planning for legal, financial, and care decisions.
How Daily Calls Track Cognitive Changes
A single GP visit is a snapshot. Daily conversations are a trend line. Here's what regular calls can detect:
Repetition Patterns
If your parent tells the same story on 3 consecutive calls — and doesn't remember the previous conversation — that's a meaningful data point for their GP.
Orientation Changes
Confusion about day of week, time of day, or recent events. "I thought it was Tuesday" on a Friday is significant if it happens regularly.
Language Changes
Increasing word-finding difficulty, shorter sentences, or inability to follow the flow of conversation. Gradual changes are harder to spot in weekly visits.
Mood Tracking
Daily calls detect mood shifts — increased anxiety, paranoia ("someone was in the house"), or sudden apathy. These can signal progression or treatable conditions like depression.
