Memory training in depression

Item does not contain fulltextMemory biases, that is, general memory impairments as well as specific mood-congruent memory biases, are important vulnerability factors in depression. Recently, computerized memory trainings have been developed to target these biases, reducing rumination and lightening depressive symptoms. This review presents three novel treatment approaches: general memory training, emotional memory training, and attention or interpretation training targeting memory processes. Results are mixed, but the computerized memory trainings that target general deficits in memory or specific emotional biases seem to be an interesting new treatment option, especially as add-ons to other interventions. However, many open questions remain. These include the mechanisms of these trainings as well as more practical aspects like the optimal number of sessions, the duration of the effects, and individual differences in trainability.5 p

Working it out: Can an acute exercise bout alleviate memory bias, rumination and negative mood?

Although it is well known that exercise reduces depressive symptoms, the underlying psychological mechanisms remain unclear. This experimental study examined the acute effect of exercise on mood, and depressotypic memory bias and state rumination. Trait rumination was tested as a possible moderator. A sample of non-regular exercisers (N = 100) was randomized to exercise or rest. After a negative mood induction, the exercise condition cycled for 24?min at moderate intensity, while the rest condition rested. Negative and overgeneral memory bias, as well as positive and negative affect were assessed after exercise/rest. To capture the lingering of negative mood and state rumination, both were assessed multiple times throughout the study. The exercise (as compared to rest) condition reported more positive affect. However, no differences were found on overgeneral memory bias, as well as depression-specific mood or state rumination measured throughout the study. Interestingly, the exercise condition showed more negative memory bias at higher levels of rumination. Individual differences in trait rumination moderated the exercise?memory bias relation, such that exercise increased negative memory bias at higher levels of rumination. It is possible that long-term exercise protocols are necessary to change cognitive processes related to depression
