Effects of Physical Exercise on Cognition in Persons with Subjective Cognitive Decline or Mild Cognitive Impairment: A Review
Journal Title: Journal of Parkinson’s Disease and Alzheimer’s Disease - Year 2017, Vol 4, Issue 2
Abstract
Alzheimer’s disease is the most common type of dementia that lacks a cure so prevention is an important aspect of care. Persons with subjective cognitive decline or mild cognitive impairment are more likely to be diagnosed with Alzheimer’s disease later than cognitively healthy populations. The purpose of this literature review was to analyze the effects of physical exercise interventions on cognition in persons with subjective cognitive decline or mild cognitive impairment. A literature search was conducted using electronic databases from the beginning dates of the databases to September-23-2016. Of the 94 randomized controlled trials generated 6 subjective cognitive decline and 9 mild cognitive impairment studies met the eligibility criteria and were included in this review. The levels of study quality for subjective cognitive decline and mild cognitive impairment were 5 strong 1 moderate and 5 strong 4 moderate respectively. Interventions were aerobic, resistance, Tai Chi or multicomponent exercise. Overall 67% (10/15) of the studies showed that the interventions improved cognition compared to control or other interventions. There is a pressing need to conduct further research to establish the optimal dose of each modality for improving cognition in these populations.
