Busy social life during 50s can signify Alzheimer's disease
Old people socialising Credit: BANG - Entertainment News BANG - Entertainment News Bang Showbiz A busy social life in your 50s could be an indicator of Alzheimer's disease. A massive study of almost half a million Brits aged 40 and older found that people with a higher genetic risk for Alzheimer's tended to report two per cent more social activity and three per cent less isolation in their 50s. Dr. Ashwin Kotwal, lead researcher at the University of California, San Francisco (UCSF), said: "We don't know if they're chasing more chatter or if others are rallying around them. Their social lives may expand in these early stages." Traditional wisdom suggests friendships and family time protect brain health by boosting "cognitive reserve". But this study highlights a reversal to the trend and suggests that alarm bells should ring if a person's schedule becomes jam packed for no obvious reason.

Having a busy social life in your 50s could actually be an early sign of Alzheimer's, scientists warn

But a surprising new US study suggests the opposite might be true, at least in the early stages.

"We don't know for sure if they are engaging more with others, or if those around them are noticing subtle changes and giving them more support.' The study, published this month in the American Journal of Epidemiology, analysed data from almost 500,000 Brits aged 40 and over, collected by the UK Biobank. It was an observational study, meaning researchers didn't track outcomes over time, but looked for associations in the data. Researchers calculated each person's genetic risk for Alzheimer's and compared it with their levels of social connectedness. These scores, known as Alzheimer's Disease Genetic Risk Scores (AD-GRS), reflect a person's inherited likelihood of developing the condition, based on known genes. But they don't guarantee someone will get the disease. They then looked at how often people felt lonely or isolated, how satisfied they were with their relationships, and how many different social activities they took part in. Previous studies have linked lower levels of social interaction with reduced brain volume and a higher risk of dementia. But in this new analysis, those with a higher genetic risk for Alzheimer's were three per cent less likely to feel socially isolated. They also reported one per cent higher satisfaction with their family relationships and took part in around two per cent more types of social activity compared to people with a lower genetic risk.

In the UK, around 982,000 people are currently living with dementia, including Alzheimer's disease. That figure is expected to hit 1.4 million by 2040. There is no cure, so spotting the condition early is crucial. An early diagnosis can help slow progression, ease symptoms, and open up access to clinical trials. According to the Alzheimer's Association, one of the first warning signs is social withdrawal. Other symptoms include asking the same questions repeatedly, losing track of important dates, and increasingly relying on memory aids or loved ones for tasks once managed alone.
