poses a substantial challenge to health, aged care and social policy. Based on
projections of population ageing and growth, the number of people with dementia
will reach almost 400,000 by 2020. Although projection methods vary, the number
of people with dementia is projected to triple between 2011 and 2050, to reach
around 900,000 by 2050.
Dementia is a leading
cause of death and burden of disease
was the third leading cause of death in 2010 (accounting for 6% of all deaths),
with an average of 25 people dying from dementia every day that year. Twice as
many women as men died from dementia (6,083 and 2,920 respectively). The number
of deaths due to dementia increased 2.4 times between 2001 and 2010 (from 3,740
to 9,003 deaths). Some of this increase is due to population ageing and growth,
but some may be due to changes in how dementia is recorded on death
certificates. Dementia was recorded as the underlying or an additional cause of
14% of deaths in 2010.
Estimates of burden of
disease quantify the amount of healthy life lost due to premature death and
prolonged illness or disability. Estimates for 2011 suggest that dementia was
the fourth leading cause of overall burden of disease, and the third leading
cause of disability burden. For people aged 65 and over, dementia was the
second leading cause of overall burden of disease and the leading cause of
disability burden, accounting for a sixth of the total disability burden in
People with dementia rely
heavily on health and aged care services
estimated 552,000 GP attendances (0.5%) in 2010-11 involved the management of
dementia. In 2009-10, dementia was a diagnosis for 83,226 (1 in every 100)
hospitalisations, and was the principal diagnosis for 12,286 (1 in every
1,000). In that year, 392,796 (0.2%) government-subsidised prescriptions were
Total direct health and aged
care system expenditure on people with dementia was at least $4.9 billion in
2009-10, of which about $2.0 billion was directly attributable to dementia. Of
this, $1.1 billion was for permanent residents in residential aged care
facilities and $408.0 million was for community aged care services.
Many people with dementia have other health
conditions, and many need high care
people with dementia aged 65 and over had a substantially higher average number
of health conditions (5.4) than all people in that age group (2.9). In 2009-10,
53% of permanent residents in residential aged care facilities had dementia.
Residents with dementia were more likely than those without dementia to require
high care (87% vs. 63%).
placed on informal carers
that, in 2011, there were around 200,000 informal carers of people with
dementia living in the community. Co-resident primary carers of people with
dementia were almost twice as likely as all co-resident primary carers to
provide 40 or more hours of care per week (81% versus 42%).
