Behavioral Activation System (BAS) was no significant difference between groups. Healthy score in active avoidance component were significantly higher than other two groups. The score of hypertensive group with medication use in passive avoidance and fight-flight system (FFS) and the score of hypertensive group without medication use in behavioral approach and fight system were significantly more than healthy group.
