Higher cholesterol levels tied to reduced risk of dementia in elderly finds study

The authors of this new study looked at the association of cholesterol levels and cognitive functions at different age groups. Results revealed that increased cholesterol levels since the 40’s led to an increased cognitive decline as the participant aged. However with age this positive correlation was stopped and ultimately reversed. In patients between ages 85 and 94 years, having higher cholesterol during middle years led to a lower risk of cognitive decline. This goes against the traditional study findings from other researchers. Authors warn that this study does not advocate raising one’s cholesterol during their 40’s to reduce the risk of cognitive decline. This is because, there is a positive risk of getting dementia among the aged if they have high cholesterol levels during their 40’s. Further high cholesterol levels do lead to an increased risk of cardiovascular disease.
