Genetics Plus Heart Health Markers Sharpen Dementia Risk
New research shows that dementia risk is best predicted by combining genetic vulnerability with cardiovascular disease markers, revealing a more precise and actionable way to identify who is most likely to develop the condition. While genes such as APOE4 and family history contribute heavily, equally powerful are modifiable factors like hypertension, obesity, and diabetes.
Here’s what we know.Genome Study Reveals True Genetic Influence on Traits
Using full genome sequencing data from more than 347,000 individuals, researchers quantified how much genetic differences explain human traits such as height, body mass index, fertility, and disease risk. The results show that genes account for roughly 30% of the variation between individuals, with higher estimates for traits like height and lower for fertility.
