Herein, we report on two clinical cases in which behavioral disturbances occurred due to frontal dysfunction. Both patients were treated successfully with behavioral intervention. In the first case, the patient's challenging behavior of repeatedly entering his wife's workplace and interrupting her work was reduced after the patient's wife changed her response to the behavior and her schedule prior to work to ensure that she spent time with him in the morning. In the second case, the patient's challenging behavior of urinating in the street was reduced by changing his walking route. The successful outcome in both cases suggests that behavioral intervention based on Antecedents, Behavior, and Consequences (ABC) analysis is useful in the management of behavioral disturbance due to frontal dysfunction.
