Decreased Cognitive/CNS Function in Young Adults at Risk for Hypertension: Effects of Sleep Deprivation

Figure 1

The effect of sleep deprivation on immediate code substitution recall (% correct) in persons classified by JNC-7 criteria of prehypertensive or normotensive. The time by Risk Group interaction was significant [multivariate F(3, 41) =4.073, 𝑃=.013, 𝜂²=.230]. Fisher’s LSD indicates a significant drop in performance at 5:30 AM, in prehypertensives (𝑃=.03).
