The purpose of this study is to examine the current management of patients and outcomes of 4500 patients with dementia in Australia through a longitudinal (subjects are assessed at several different times during the course of the study), multiple cohort design (design containing group of individuals that share same characteristics) by collecting prospective real time clinical, treatment, health status and economic data. The study will identify the relationships among demographic variables, prognostic features(prediction of the probable course and outcome of a disease), geographic region, treatment options and clinical, economic and health status (activities of daily living and caregiver impact) outcomes. A complete record of patient care will be collected to provide detailed information on the management and outcome of dementia and the profile of patients at participating sites. The data will be used to build models looking at the effect of dementia management on principal clinical events, health status and economic outcomes. This will provide the foundation for subsequent objective and prospective evaluation of strategies based on real-time data collected in this study for the optimal treatment of dementia in Australia. This study does not involve or require any treatment or medication by Sponsor, but will instead examine the influence of a whole range of routinely used treatment management strategies for dementia on clinical and economic outcomes among dementia patients in Australia. This 'practice based' approach is increasingly widely used and is a useful tool for elucidating the relative effectiveness of different management strategies and for exploring relationships between patient characteristics, treatment and outcomes.

NA - The registry will collect information irrespective of treatment prescribed.
