摘要: Mild cognitive impairment (MCI) describes a transitional state in progression from normal
aging to dementia, especially Alzheimer's disease (AD). Currently, there is no effective pharmacological
treatment that offers a long-term beneficial effect to delay the progression to dementia. There is
growing evidence that supports an important role of non-pharmacological cognitive interventions.
Therefore, it is warranted to clarify the distinct forms of cognitive interventions and their effects based
on previous clinical trials. We aimed to provide a review of clinical trials of non-pharmacological
cognitive interventions for MCI and to address the characteristics of the study patients, cognitive intervention
programs and short-term / long-term benefits of the interventions. A total of 32 articles were identified according
to the inclusion criteria. The results showed positive effects for both objective and subjective outcome variables, and
these effects persisted from 1 month up to 5 years. Although many of the positive effects were related to improvement in
trained tasks, alterations in neuroimaging and the transfer effects shown by some studies are encouraging. Future research
in this area requires a larger sample size with a wider spectrum of MCI, more instructive outcome measures and a longer
follow up duration.
