Loneliness affects between 10 and 20% of the population. It is known that loneliness can promote depression, lower the immune system, and even effect development. In order to measure the effects of loneliness on the brain’s mechanisms, a study was carried out using data from an English database. This database collects, among other things, genetic data and MRI results from approximately 40,000 people. See acast.com/privacy for privacy and opt-out information. Learn more about your ad choices.
