[Proposal of criteria for clinical diagnosis of mild cognitive impairment, dementia and Alzheimer's disease].
The most widely accepted criteria for Alzheimer's disease (AD) diagnosis (NINCDS-ADRDA and DSM-IV) do not allow to differentiate accurately between AD and other degenerative dementias which have recently formulated criteria for its clinical diagnosis. Therefore, it is necessary to bring AD diagnostic criteria up to date in order to optimise their specificity, by assessing its most specific clinical manifestations, its most representative markers and those features typical of other diseases which are usually taken into account for a differential diagnosis. According to the latest reports on the subject, the disturbances suffered by memory, behaviour and the rest of cognitive and executive functions must be equally considered when establishing the syndromic diagnosis of dementia; this will always require the coexistence of an evident functional impairment. Due to this, the concepts of "dementia" and "mild cognitive impairment" should be clearly distinguished. For the time being, AD can only be diagnosed when dementia has been proved and this shows a series of cognitive, behavioural and neurological features which are representative of it. Nevertheless, some diagnostic markers appear to be precocious and specific enough to try to identify those patients who suffer from mild cognitive impairment due to an incipient stage of AD. We are suggesting some criteria for the clinical diagnosis of dementia, mild cognitive impairment and AD that seem to be more detail
