Acting on a whim, behaving with little or no forethought, reflection, or consideration of the consequences. Intermittent or infrequent impulsive behavior is common and normal. Characterized by difficulties controlling or restraining impulsive behavior. Classified with other disruptive and conduct disorders. Repeated episodes of impulsive, uncontrollable aggression directed at people or destruction of property. In general, stolen items are typically low-value to the person. Stealing is the result of momentary impulse they don"t think through, pure impulsivity. Results in pleasure, excitement, gratification = positive reinforcement. Shoplifting is relatively common, but kleptomania affects < 1% of the population. 3x more common in females than males. State of tension precedes aggressive outburst the urge gets stronger and stronger then bum. Possibly the result of reduced production and transmission of serotonin. Some indication that ssrris can curb aggression. Not all arson is committed by pyromaniacs.
