Social Network Index

Social network size is a foundational metric for evaluating the breadth of an individual’s social connections, which play a critical role in cognitive and emotional well-being. Larger and more diverse social networks are associated with enhanced neurological health, including better cognitive function, reduced risk of dementia, and improved resilience to stress and depression. Social connections stimulate the brain through conversation, shared experiences, and emotional support, all of which promote neuroplasticity and reduce the negative effects of isolation. By assessing the size of an individual’s network, researchers and clinicians can gain valuable insights into their level of social engagement and potential areas for intervention to enhance brain health.
