Consequences of unaddressed hearing loss include impaired communication and reduced psychosocial well-being. Hearing loss also has close links to dementia as one of the primary modifiable risk factors.3 The 2017 World Health Assembly Resolution Prevention of deafness and hearing loss calls on hearing health-care stakeholders to develop and implement strategies for improved service provision, especially in low- and middle-income countries.en© World Health Organization 2019.
