Keep connected

Research suggests that social isolation is linked to an increased risk of dementia. So keeping connected to the people around us is another good way to give back to our brains.

In 2020, researchers published an analysis showing that social isolation could be a factor in around 4% of dementia cases.

Scientists aren’t sure whether social isolation is a risk factors for dementia, or whether it’s a symptom of the condition. But one thing is for certain: keeping connected is good for our brain health.

Spending time with loved ones, having virtual catch-ups or volunteering can also help us feel happier and healthier in general.

How do we know this?

Many studies have identified a link between loneliness, social isolation and a decline in memory and thinking skills. For example, researchers in the UK and China found that people who were socially isolated had lower brain volume in the areas associated with memory and thinking. They were also 26% more likely to develop dementia.

We need more studies to understand the exact nature of the link between social isolation and dementia, but it’s clear that a relationship does exist. Keeping connected to those around you is an important and fulfilling way to show your brain some love.
