Effect of Exercise on Dementia: A Narrative Literature Review

Abstract

Dementia is an acquired condition affecting memory and intellectual functions due to brain disease. The number of older adults with dementia is projected to grow from 50 million worldwide in 2017 to 80 and 150 million in 2030 and 2050. Medications to improve cognitive function have contraindications and notable side effects. Exercise training stands out as one the promising nonpharmaceutical therapies to enhance cognitive health in older adults affected by all-cause dementia. Physical exercise can support healthy aging into independent body function, psychological well-being and cognition. Through a critical analysis of current research, this review provides valuable insights for healthcare professionals, researchers, and policymakers seeking effective approaches to alleviate the impact of dementia through lifestyle interventions.
