Cognitive Rehabilitation in Normal Aging and Individuals with Subjective Cognitive Decline

Abstract

Aging-related changes include declines in especially episodic memory, working memory, processing speed, and executive functions. Cognitive rehabilitation programs for healthy older adults with subjective cognitive decline consist of brain training, strategy training, and multimodal interventions. In general, these interventions show small improvements within the trained domain (near-transfer effects), but limited benefits on untrained cognitive domains or everyday functioning (far-transfer effects). Multimodal approaches might be more effective to enhance multiple cognitive domains and everyday functioning. However, the current lack of clear efficacy of cognitive rehabilitation techniques in healthy older adults might be explained by methodological shortcomings of previous studies and the notion that aging-related cognitive decline is not considered to reflect impairments. Future interventions with longer follow-up duration should therefore focus more on psychoeducation on normal cognitive aging and target self-efficacy and worrying to diminish subjective cognitive complaints.
