This systematic review investigates the effects of cognitive interventions (e.g., cognitive stimulation, cognitive training, cognitive rehabiliation) on cognitive outcomes in individuals with amnestic mild cognitive impairment (A-MCI).

Results indicated cognitive interventions for A-MCI improved global cognitive functioning, particularly memory. Strategies used included visual imagery, spaced retrieval, errorless learning, and external aids (e.g., calendars). Evidence for maintenance of skills was mixed. Methodological limitations of the studies included small sample sizes, heterogeneity of treatment techniques and instruments, and non-controlled experimental study designs.
Goal-oriented rehabilitation for A-MCI appeared more beneficial when delivered on an individual basis. Group cognitive interventions for A-MCI may be valuable in improving access and reducing cost of treatment, even though they did not demonstrate better results.
Computerized cognitive training in A-MCI did not generalize well to untrained tasks.
