Data in profile: Dementia in Tasmania

Dementia is a condition that affects the ability to perform daily tasks, significantly impacting both people living with dementia and their loved ones.  

As Tasmania’s population ages, dementia is becoming a pressing public health issue. By 2042, more than 25% of the Tasmanian population will be aged 65 and over.  

But when does forgetfulness turn into a medical condition? Here’s a look at dementia and the resources available in Tasmania. 

As primary care is often the first contact a person has with the health system, health professionals like GPs play an important role in the diagnosis and ongoing management of dementia. 

What is dementia? 

Dementia is the broad term that refers to over 100 different diseases that impair brain function.  

Dementia affects mood, memory, thinking, and behaviour.  

While it’s more common in people over 65, it is not a normal part of ageing and can happen to anyone.  

Common signs include frequent forgetfulness, confusion, difficulty with everyday tasks, and mood changes like depression or anxiety. Behavioural changes such as restlessness or disrupted sleep can also be warning signs. Early signs to watch for include trouble remembering recent events, getting lost, and difficulty with language. 

Though there is currently no cure, treatment is available to help manage many of the symptoms, and support services can provide assistance for those affected.  

Dementia rates 

According to Dementia Australia, in 2024 it is estimated that there are more than 10,600 people living with all forms of dementia in Tasmania. This figure is projected to increase to around 16,500 by 2054.  

Dementia and other health conditions 

Dementia often co-exists with other health conditions like heart disease, diabetes, high blood pressure, and depression, complicating care and requiring more comprehensive management. According to the Australian Institute of Health and Welfare data, people with dementia are likely to also experience: 

• heart disease is present in around 30% of people with dementia 

• diabetes is found in 20% of people with dementia  

• depression or anxiety affects about 40% of people with dementia 

• chronic lung disease and stroke-related conditions frequently co-exist with dementia, further reducing quality of life. 

• people with intellectual disabilities are at a higher risk of developing dementia than the general Australian population 

Managing dementia  

Managing dementia involves a mix of medication, therapy, and lifestyle changes. Early diagnosis is key to slowing its progression. A range of support, resources, education and counselling is available for individuals and caregivers.

• Tasmanian Government’s Community Dementia Service is a team of health professionals who offer consultation, assessment, information and nursing care services to people with dementia living in the greater Launceston community. Their clinical nurse consultant can provide assessment, including cognitive assessment (with GP referral) and support in the North, outside of the Launceston Area. 

• Dementia Australia: National peak body with information and support services. 

• Carer Gateway: National service delivered in Tasmania through Care2Serve, offers practical and emotional support for caregivers. 

Preventing dementia 

Although there is no cure for dementia, research suggests that certain lifestyle factors can reduce the risk or delay its onset. These include regular physical activity, healthy diet, mental stimulation such as reading, puzzles and learning new skills, social engagement, and managing chronic conditions such as diabetes, high blood pressure and cholesterol. 

The path forward 

With Tasmania’s ageing population, the demand for dementia care will continue to grow. In Australia, the economic burden of dementia is significant. According to Dementia Australia, the total cost of dementia to the healthcare system is expected to reach $18.7 billion by 2025. Early diagnosis, preventive measures, and expanded community support are crucial in addressing this challenge.
