Strained family relationships could increase the risk of dementia.

Scientists found that people unhappy with their family life face a higher chance of developing the degenerative condition – which causes a decline in thinking, memory, and reasoning skills.

The study analysed data from 104,093 UK adults aged between 40 and 69, all of whom were dementia-free at the start.

Participants were tracked for more than 13 years, during which 1,359 people developed dementia.

Researchers compared diagnosis rates with how satisfied individuals felt about their relationships.

Those who reported dissatisfaction with family relationships had a 34 per cent higher risk of dementia, while those who were very dissatisfied saw their risk jump by 66 per cent.

In contrast, dissatisfaction with friendships showed no significant link.

The study, published in the journal Alzheimer’s + Dementia, concluded: “The findings suggest that family relationship quality may be an important consideration in dementia risk assessment.”
