A surprising new study has revealed that middle-aged adults in the early stages of Alzheimer’s disease may actually become more social, not withdrawn as previously believed.
Researchers analyzed data from nearly 500,000 people aged 40 and above in the UK and found that those with a higher genetic risk of Alzheimer’s reported stronger social lives, close family ties, and less loneliness.
Dr. Scott Zimmerman from Boston University, the study’s lead author, said, “We expected social withdrawal, but instead we saw people becoming more socially active.”
Published in the American Journal of Epidemiology, the study suggests that early changes in memory or thinking may push people to connect more with family and friends — possibly as a way to seek daily support.
Traditionally, dementia has been linked to loneliness, but experts say it’s unclear whether isolation causes dementia or results from it. This study shows that people may become more engaged before they even get diagnosed.
Dr. Ashwin Kotwal of UCSF explained that social networks may actually grow in early Alzheimer’s cases. The research doesn’t reject earlier studies, but it adds depth by showing a possible two-way relationship between dementia and social behavior.
Dr. Ruijia Chen added that the findings support the idea that social interaction may protect brain health. Researchers estimate that around 30% of Alzheimer’s cases could be linked to lifestyle factors like exercise, sleep, mental health, and even loneliness.
Dr. Jacqueline Torres, a co-author, emphasized the need to create more opportunities for meaningful social interaction at all stages of life to support mental wellbeing.
