Most Australians wait years for dementia diagnosis. AIHW shows why.
The AIHW Living with Dementia Survey (266 people with dementia, 1,648 carers) found 39% received their diagnosis more than three years after symptoms appeared. The most common barrier was delays in testing and specialist access (22%). GP misattribution of symptoms — treating cognitive decline as normal ageing — was named by 18% of respondents.
Women were more likely to receive a timely diagnosis than men (43% diagnosed within one year versus 33%). Both figures point to a system still too slow to connect people to diagnosis, carer support, and the planning conversations that follow it.
Dementia is Australia’s leading cause of death. More than 400,000 Australians live with it. And according to new AIHW data published today, 39% of people waited more than three years from their first symptoms to receive a diagnosis.
Three years. Of growing confusion, of attributing memory lapses to stress or poor sleep or ageing, of family members watching something shift and not knowing what to name it. The AIHW’s Living with Dementia Survey drew on responses from 266 people with dementia and 1,648 carers, and what it found is both a system problem and — at 18% of respondents naming it — a general practice problem.
The most common barrier was delays in testing and specialist access (22%). The second was GP misattribution: clinicians treating early cognitive symptoms as normal ageing rather than investigating further. That is not a comfortable finding. But it is a useful one.
What the data shows
The survey found only 61% of people received a diagnosis within three years of symptom onset. Forty-three percent of women were diagnosed within the first year, compared with 33% of men — a meaningful difference, though the direction of the gap (women diagnosed more quickly) sits against the broader literature on women being more frequently dismissed in medical consultations. More than 25% of respondents waited more than a year before seeking professional advice at all.
The carers’ picture is equally pointed. Many described feeling isolated, overwhelmed, and unsupported — not just before diagnosis, but after it. Post-diagnostic support connections were described as inadequate. The diagnosis itself, when it came, was not always followed by a clear pathway.
Dr Stephanie Daly, RACGP Chair of Dementia, described a diagnosis as “important and empowering” and called for active investigation of cognitive symptoms rather than dismissal. That framing matters: a diagnosis is not merely a label. It is access to planning, support, clinical management, legal and financial preparation, and the conversations a family needs to have while the person can still meaningfully participate in them.
Both sides of this story
The case for earlier diagnosis is strong. RACGP guidelines, the National Dementia Action Plan, and every peak body in this space advocate for it. Timely diagnosis means better access to post-diagnostic support, the opportunity to enrol in clinical trials, and — for conditions like Lewy body dementia or frontotemporal dementia, where diagnostic accuracy matters for management — the best chance of matching treatment to cause.
The honest complication is that early diagnosis is hard. The presenting features of early dementia — word-finding difficulties, spatial disorientation, personality shifts, subtle executive dysfunction — overlap significantly with normal ageing, anxiety, depression, poor sleep, and thyroid disease. A GP who works up every 65-year-old with occasional forgetfulness would create enormous anxiety and cost. Clinical judgement about when to investigate and when to reassure is not the same as dismissal.
What the 18% figure suggests is not that all GPs are dismissing cognitive symptoms carelessly. It is that there is a meaningful subgroup of patients for whom the signal was there but not acted on — and that being alert to that possibility is worthwhile clinical maintenance.
The other structural tension is referral wait times. Even when a GP suspects early dementia and refers appropriately, the delays in accessing geriatrician and memory clinic appointments are real. The 22% who cited testing and specialist access as the main barrier were not encountering a GP problem — they were encountering a capacity problem that sits well above the consulting room.
2 cents this week
Lower your cognitive assessment threshold. When a patient or their family member raises concern about memory or thinking changes — even tentatively, even framed as “they’re probably just tired” — that is the signal to do a structured assessment rather than offer reassurance. The GPCOG takes six minutes and includes a brief informant component. The MoCA is sensitive to early executive and visuospatial deficits that the MMSE can miss. Use them.
Document your clinical reasoning explicitly. When you see early cognitive symptoms and decide to monitor rather than refer, write down what you observed and why you are watching and waiting rather than investigating further. This creates a clear trail for your next consultation and for the patient’s record if someone else sees them. “Appears cognitively intact for age — no formal assessment indicated at this visit” is a defensible note. “Memory concerns discussed” is not.
Know your post-diagnosis referral pathways before you need them. Dementia Support Australia (1800 100 500) provides post-diagnostic support at no cost to patients. My Aged Care is the entry point for care package assessment. If your practice does not have a brief resource sheet for newly diagnosed families, building one now means you are not searching at a difficult consultation.
Name the diagnosis clearly. The evidence on post-diagnostic wellbeing consistently shows that clarity is better than circumlocution. “The assessment suggests early Alzheimer’s disease” is a harder sentence to say than “there are some memory changes we’ll keep an eye on,” but it gives the patient and family what they need to begin planning.
A diagnosis is what allows someone to become the person who organises their affairs, tells their family, makes peace with hard things while they still can. Three years is a long time to wait for that.
Verdict: yes — review your cognitive assessment practice, and know your post-diagnosis pathways.

Frequently asked questions
-
What cognitive screening tools are recommended in Australian general practice?
The RACGP recommends using a validated cognitive assessment tool when a patient, carer, or GP has concerns about cognition. Commonly used options in Australian general practice include the MMSE (Mini-Mental State Examination), the MoCA (Montreal Cognitive Assessment), and the GPCOG (General Practitioner Assessment of Cognition) — the last of which was specifically designed for a GP consultation timeframe and includes a brief informant component. The choice depends on the clinical context. For a brief screen with an informant available, GPCOG is well-suited to a standard 15-minute consultation.

What happens after a dementia diagnosis — what should I connect patients to?
Following diagnosis, key referral pathways in Australia include Dementia Support Australia (1800 100 500) for post-diagnostic support, My Aged Care for care coordination and package assessment, the patient's local memory clinic or geriatrician for complex cases, and carer support via Carers Australia. Many patients and carers report not knowing what support existed or how to access it — a brief written resource or a follow-up call from your practice nurse can substantially improve uptake.
