[Description and validity of Enedam test-retest. A structured interview for the diagnosis of Alzheimer's, multi-infarction dementias and dementias of other etiologies based on the CIE-10 and DSM-III-R].

The SIDAM, a new clinical structured interview for the diagnosis and measure of dementia according to DSM-III-R and ICD-10, is described. This instrument comprises a clinical overview, several cognitive tests, including the Mini-Mental State, and a section for clinical judgement and information coming from others. Every item relies on DSM-11-R and ICD-10 algorithms. The SIDAM has a hight test-retest reliability on the clinical diagnosis and the different diagnostic criteria. It is a brief (28 minutes), practical screening instrument. Good congruence is found between SIDEM, DSM-III-R and ICD-10, and the corresponding ICD-9 expert diagnosis. Furthermore the SIDAM Total Score (SISCO), allows a good measurement of low level of cognitive impairments and provides quantification of severity of cognitive disorders. The SIDAM has been translated and adapted into Spanish.
