Is There a Role for Physical Activity in Preventing Cognitive Decline in People with Mild Cognitive Impairment?

Mild cognitive impairment (MCI) is a common clinical syndrome that identifies people at high risk of developing dementia. Although treatments for MCI are currently unavailable, preliminary evidence has identified potential neuro-protective effects of physical activity, which may lead to improved outcomes. However, there is uncertainty regarding the effectiveness, feasibility and acceptability of this treatment strategy. These uncertainties require further investigation before physical activity interventions can be recommended for routine care.
