Early life factors linked to dementia risk

New research suggests that factors present at birth or during early childhood may influence the likelihood of developing dementia later in life, challenging the traditional view that dementia is primarily a disease of old age.

Shift in dementia prevention focus

Scientists now believe that dementia is not just a result of aging but may stem from vulnerabilities that develop much earlier, even before birth, requiring a new approach to prevention that includes younger populations.

Swedish study identifies risk factors

A large study in Sweden, examining over 1.5 million people born between 1932 and 1950, found that certain birth-related factors are associated with an increased risk of dementia in adulthood, though they do not directly cause the disease.

Specific birth factors and dementia risk

The study identified three factors: being part of a multiple pregnancy, being born to a mother over 35, or being born less than 18 months after a sibling. Each of these factors was linked to a 5 to 16% higher risk of developing dementia later in life.
