Social isolation can potentially harm brain structure and cognitive performance, suggesting an increased risk of conditions like Alzheimer's dementia.
The study indicates a lack of quality social interaction can lead to a decrease in the hippocampus's volume, crucial for memory formation and retrieval, and poorer cognitive performance.
However, maintaining a strong social network could help preserve brain structure, providing a potential preventive strategy for dementia onset.
The findings underline the importance of targeting those at risk of social isolation with tailored strategies to enhance their social contact.
