Positive effects of computer-based cognitive training in adults with mild cognitive impairment

Topic: Risk, prevention and care in population studies
Considering the high risk for individuals with amnestic Mild Cognitive Impairment (A-MCI) to progress towards Alzheimer's disease (AD), we investigated the efficacy of a non-pharmacological intervention, that is, cognitive training that could reduce cognitive difficulties and delay the cognitive decline. For this, we evaluated the efficacy of a 12-week computer-based memory-attention training program based on recognition in subjects with A-MCI and compared their performances with those of A-MCI controls trained in cognitively stimulating activities. The effect of training was assessed by comparing outcome measures in pre- and post-tests 15 days before and after training. To evaluate the duration of training benefits, a follow-up test session was performed 6 months after memory and attention training or cognitively stimulating activities. Outcome measures showed that the trained group, compared to control group, improved episodic recall and recognition. Six months after training, scores remained at the level of the post-test. Since the training program was exclusively based on recognition, our results showed a generalization from recognition to recall processes, which are memory components that represent part of the core cognitive impairments in individuals at risk of converting to AD. Thus, cognitive training based on recognition holds promise as a preventive therapeutic method and could be proposed as a non-pharmacological early-intervention strategy. Future investigations need to focus on methodological constraints and delineating possible neuroplastic mechanisms of action.
Key findings
- Outcome measures showed that the trained group, compared to control group, improved episodic recall and recognition.
- Since the training program was exclusively based on recognition, our results showed a generalization from recognition to recall processes, which are memory components that represent part of the core cognitive impairments in individuals at risk of converting to AD.

How this study scored 62/100
Published in a peer-reviewed journal, and it is a randomised controlled trial. Scored zero for sample size and effect reported because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 36 of the 58 points we could judge it on, which is 62 out of 100.
