World Health Organization recommends social activity to lower dementia risk

The World Health Organization (WHO) has updated its dementia‑prevention guidelines to include regular social contact as a key factor. Studies show that social isolation increases the risk of cognitive decline, while frequent interaction with friends and family can keep the mind fit, reduce stress, and encourage healthier habits. WHO estimates that about five percent of dementia cases could be avoided if social isolation were eliminated, and that regular social activities may delay the onset of dementia by up to five years. Currently more than 57 million people worldwide live with dementia, with nearly ten million new cases each year. The guidance emphasizes that, alongside a balanced diet, exercise, and avoidance of alcohol, tobacco, diabetes, and high blood pressure, maintaining social connections is a modifiable way to reduce dementia risk.
