The efficiency of CAMDEX
in the diagnosis of dementia and its subtypes.
et al, CAMDEX
, a standardised instrument for the diagnosis of mental disorder in the elderly with special reference to the early detection of dementia.
The standardized procedure adopted for the dementia register in 1993 was based largely on the CAMDEX
diagnostic guidelines , but supplemented by newly published criteria for dementia of Lewy-body type .
7] compared informant accounts, as documented using the CAMDEX informant interview , with results obtained from cognitive testing and found these to be `highly consistent'.
The CAMDEX informant interview  was used to obtain information about the onset, symptom profile, course and duration of the dementia.
Patient assessments: Patients' cognitive function was assessed using the MMSE , the Abbreviated Mental Test Score (AMTS)  and by a selection of tests from the CAMCOG component of the CAMDEX , including those examining praxis and visual agnosia.
All patients aged 65 years or over who fulfilled the CAMDEX
criteria for mild or moderate dementia  and had an informant in contact at least once a week were selected.

digit span test, the Kendrick Battery Object Learning and Digit Copying Tests, the Wechsler Test for immediate and delayed recall of logical memory function, the ADL Scale of Lawton and Brody consisting of the Physical Self-maintenance Scale and the Instrumental Activities of Daily Living Scale, and the CAMDEX
Cognitive Examination (CAMCOG)[23-27].
Using all the available information from the subject (although not the results of the cognitive tests per se) and informant and employing the detailed criteria from the CAMDEX, a clinical diagnosis of dementia was made together with a rating of its severity.
Level of education was ascertained by two items from the CAMDEX schedule: the age at which subjects left school, categorized into (14 years and under/15 years and over) and number of years of further education after leaving school, categorized into (none/1 or more years).
Visual and hearing impairments were assessed in the CAMDEX schedule and dichotomized into no impairment/some difficulty or totally impaired.
