| Annotation | Our conception of ageing and cognitive deterioration is that cognitive decline becomes more common with age, and dementia may be regarded as one extreme of the continuum. An alternative conception is that the cognitive process is spared by the ageing process itself, and that cognitive functioning of normal older people and those with slight cognitive impairment, a CDR (Clinical Dementia Rating) score of 0.5 (suspected dementia), should be different. The authors examined changes in the screening test performances of 170 older Japanese over a 5-year period, and found that: the CDR 0 (normal) participants did not show remarkable changes, whatever age; and the sub-items of orientation, memory, and the like were useful for distinguishing older normal people from early AD patients. The results support the idea that dementia is better conceptualised as an age-related than as an ageing-related disorder, and that a CDR score of 0.5 should be considered very mild AD. (RH). |
