MENTAL AND BEHAVIOURAL DISORDERS (F00-F99)
Mental and behavioural disorders were the underlying cause of 6,235 doctor certified deaths in 2009, a 2.7% increase from the 6,073 doctor certified deaths in 2008. The majority of total deaths due to Mental and behavioural disorders are usually certified by a doctor.
Dementia (F01, F03) accounted for the majority of the increase in doctor certified deaths due to Mental and behavioural disorders in 2009, increasing from 5,566 doctor certified deaths in 2008 to 5,729 in 2009. This increase is consistent with the annual increases since 2006 and may be attributable in part to the aging population in Australia.
Of those deaths due to Mental and behavioural disorders certified by a doctor, 2,235 deaths were male and 4,000 were female. The median age at death for all doctor certified deaths attributed to Mental and behavioural disorders was 87.7 years which is higher than the reported 82.2 year median age at death for all doctor certifier deaths.
