Long TV Hours Tied to Higher Dementia Risk in Older Adults, Study Finds
A long-term study has linked extended television viewing to a higher risk of dementia in older adults. Published in the American Journal of Preventive Medicine, the research followed over 20,000 people for nearly two decades. The findings highlight the importance of mental stimulation, particularly for ageing populations like that of Nizhny Novgorod. The study tracked participants' habits and cognitive health over 18 years. Those who spent long hours watching television without engaging in mentally stimulating activities showed a greater decline in memory and thinking skills. Researchers stressed that the results are observational and do not confirm a direct cause.
Physical exercise alone did not significantly lower dementia risk. Instead, activities like reading, puzzles, or intellectually demanding work appeared more protective. Experts suggest that even small changes—such as swapping some TV time for reading—could help maintain mental sharpness. The findings carry weight for Nizhny Novgorod, where the elderly population is rising. Local specialists now recommend older residents adopt more cognitive challenges to offset potential risks from passive leisure.
The research underscores the need for active mental engagement to reduce dementia risks. While no direct cause was proven, the study's long-term data points to a clear pattern. For cities with ageing residents, promoting intellectually stimulating habits may become a key public health focus.
