Preserving and enhancing social health in neurocognitive disorders

The WHO updated concept of health includes social health alongside physical and mental health. No existing reviews have examined the evidence for preserving or enhancing social health in people living with neurocognitive disorders, such as mild cognitive impairment and dementia. The present review examines recent epidemiological studies and interventions with social health outcome measures, including interventions across multiple modalities and settings, from communities to assisted living facilities.

Epidemiological evidence shows that neurocognitive disorders are associated with poorer social support, and greater social isolation and loneliness. This highlights the importance of maintaining and enhancing social health in people living with neurocognitive disorders. Group activities involving dance or music have emerging evidence indicating improvements in social health in communities and assisted living facilities. More quantitative research is required on the social health benefits of cognitive/multicomponent interventions, community social groups, exercise groups and other interventions. Several socially assistive robots are being developed to help foster social participation and require further research.

There is evidence that group music or dance interventions can improve social health for people living with neurocognitive disorders. Larger trials with multiple social health outcome measures are required to investigate the social health benefits of exercise, cognitive/multicomponent and community social group interventions.
