Cognitive intervention programs for individuals with mild cognitive impairment: systematic review of the literature
Jean L, Bergeron ME, Thivierge S, Simard M.. The American journal of geriatric psychiatry : official journal of the American Association for Geriatric Psychiatry, 2010-04-01
Topic: Risk, prevention and care in population studies
This systematic literature review addressed the efficacy of 15 cognitive intervention programs that have been tested in individuals presenting with mild cognitive impairment of the amnestic type (MCI-A) possibly at risk to progress toward dementia. MEDLINE, PsycINFO, and Current Content databases were searched using the following key terms: cognitive training, cognitive stimulation, cognitive rehabilitation, neuropsychological intervention, memory training, memory stimulation, and Mild Cognitive Impairment. The data showed statistically significant improvements at the end of training on 44% of objective measures of memory, when compared with 12% of objective measures of cognition other than memory. Statistically significant improvements after treatment were obtained on 49% of subjective measures of memory, quality of life, or mood. Samples sizes ranged from 1 to 193 patients with MCI-A but were usually < or =30. Five studies were randomized controlled trials, eight were quasiexperimental designs, and two were single-case investigations. Some programs focused only on memory, whereas other programs used multifaceted approaches targeting two or more cognitive functions. Eight were offered in groups, and seven took place on an individual basis. Recommendations to improve cognitive interventions in MCI-A are proposed, such as using large samples and a robust experimental design, as well as the implementation of a standardized cognitive training manual. Well standardized and validated direct and indirect measures of efficacy and noncognitive outcomes are also a crucial issue. A consensus meeting among all the experts working on cognitive training in this population should occur to provide guidelines to improve this treatment option.
Key findings
- The data showed statistically significant improvements at the end of training on 44% of objective measures of memory, when compared with 12% of objective measures of cognition other than memory.
- Statistically significant improvements after treatment were obtained on 49% of subjective measures of memory, quality of life, or mood.

How this study scored 72/100
Published in a peer-reviewed journal, and it is a systematic review of all the studies on the question. Scored zero for 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 42 of the 58 points we could judge it on, which is 72 out of 100.
