A large international study involving over 72,000 older adults looked at how sensory health affects mental health. Researchers tracked participants for up to 10 years to see if having vision or hearing problems led to an increase in depression cases.
The findings showed that people with both vision and hearing impairments had a higher risk of developing depression compared to those with no impairments. Specifically, the study found that hearing loss alone increased risk, as did vision loss alone. The risk was notably higher for those with dual sensory impairments, especially in Western countries and among individuals with college educations.
Because most of the data comes from Western countries, the results might not apply to everyone equally. It is important to remember that this study shows a link between these conditions rather than proving one causes the other. These findings suggest that doctors may need to check both sensory health and mental health together to better support older adults.
