The study investigated the relationship between cholesterol levels and mental processing. Reaction times were assessed in 279 students, aged 18 to 25, by subjecting them to a series of tests that measured their decision times and movement times.
The study found that lower cholesterol levels were associated with slower decision times and slower movement times.
The data from this study suggests that higher cholesterol levels are related to higher cognitive efficiency.
