Introduction: The scientific literature related to Dementia is extensive. The Dementia Australia website includes a link to the document; Clinical Practice Guidelines and Principles of Care for People with Dementia. This document over 100 pages, was funded by the National Health and Medical Research Council (NHMRC) Partnership Centre for Dealing with Cognitive and Related Functional Decline in Older People and endorsed by; Alzheimer’s Australia, Australian and New Zealand Society for Geriatric Medicine, Australian College of Rural and Remote Medicine, Exercise and Sports Science Australia, Occupational Therapy Australia, Speech Pathology Australia, The Royal Australian and New Zealand College of Psychiatrists and The Royal Australian College of General Practitioners.
Methods: In order to analyze the scientific literature on dementia, much of which is utilized when formulating professional guidelines, a Pubmed and Cochrane Library search was performed. A Pubmed MESH database search utilizing the term dementia resulted in 41 MESH terms. The first seven entered as a PubMed search string combination; Selecting search filters [last year] and trial type [clinical trial, randomised controlled trial, systematic review or meta-analysis] resulted in 212 records. 139 were systematic reviews or meta-analysis. The Cochrane Library search term; ‘dementia’ resulted in 195 records. However 29 were not directly on dementia, although some topics such as delirium maybe related. 166 dementia records identified from the Cochrane library search were categorized.
Results: Categorization of the records from the Cochrane library search resulted in the following categorical breakdown; diagnostic [13.5%], medicinal [42.5%], alternative or other treatments [18.5%], natural or herbal therapies [14.5%], psychological [9.0%], and exercise [2.0%].
Conclusions; The scientific literature related to dementia is complex and vast.
