Research findings have shown that persistent loneliness significantly increases the risk of dementia.

Dr. Martina Lucetti's team at the University of Florida College of Medicine conducted a meta-analysis on the relationship between loneliness, dementia, and cognitive impairment by synthesizing various aging studies and published research data. This included data from approximately 600,000 people worldwide.

 

Analysis results showed that loneliness increases the risk of dementia, Alzheimer's disease, vascular dementia, and cognitive impairment caused by all factors. Specifically, loneliness was found to increase the risk of developing dementia by 31% and the risk of cognitive impairment by 15%. This association remained even after adjusting for other risk factors for dementia.

The negative effects of loneliness on physical and mental health are already well known. The researchers stated, "This is a very important discovery, showing that loneliness is a very significant risk factor for future dementia development," and "It has been confirmed that loneliness is very important for future health in various ways, including longevity."

 

Dr. Luketi pointed out one hopeful aspect of this study. Loneliness is a modifiable risk factor. He said, "The types and causes of loneliness that can affect cognitive symptoms across the continuum of dementia are diverse," and "Addressing loneliness and increasing social bonds could have a positive impact on cognitive health in old age."

 

===============

 

Loneliness leads to a prolonged period.

I know it's also bad for mental health.

 

It can lead to dementia in the worst case.

Isn't it too scary?

 

Negative thoughts are not good for the mind.
