Learn about intermittent explosive disorder
Intermittent explosive disorder is a mental health condition that is characterized by impulsivity, hostility, and recurrent aggressive outbursts. IED is a type of impulse control disorder in which those who are diagnosed are unable to resist the urge to do something harmful to themselves or others. Additionally, the violent behaviors and angry outbursts associated with this disorder are grossly out of proportion to the situation. Individuals with IED may attack others and their possessions, sometimes causing bodily harm and property damage. Aggressive consequences associated with this disorder can include road rage, domestic violence, or work place violence.
This disorder typically begins in the early teens and is diagnosed after an individual has at least three episodes of impulsive aggressiveness at any time in their life. Those with IED describe their aggressive episodes as spells in which the explosive behavior is preceded by a sense of tension or arousal and then followed by a sense of relief. After the sense of relief wears off the individual usually feels upset, remorseful, or embarrassed about their behavior. While intermittent explosive disorder can be extremely disruptive, with the proper treatment and medication you can learn how to get your anger under control and be able to react more appropriately to specific situations.
Intermittent explosive disorder statistics
According to the National Institute of Mental Health intermittent explosive disorder affects as many as 7.3% of adults, which is 11.5-16 million Americans, in their lifetimes. Of those in the United States diagnosed with IED, 67.8% had engaged in direct interpersonal aggression, 20.9% in threatened interpersonal aggression, and 11.4% in aggression against objects
Causes and risk factors for intermittent explosive disorder
It is thought that the cause of intermittent explosive disorder is a combination of biological and environmental factors.
Genetic: There may a genetic component that causes intermittent explosive disorder to be passed down from parents to children.
Physical: Research findings have found that IED may be the result of abnormalities in areas of the brain that regulate behavioral arousal and inhibition. Research has indicated that there may be differences in the way serotonin, a chemical in the brain, works in those who have this disorder. Additionally, research indicates that those with IED have abnormalities on the front portion of the brain. These areas of the brain appear to be involved in information processing and controlling movement, both of which are unbalanced in individuals with this disorder.
Environmental: Some individuals believe that IED is caused by growing up in an environment where harsh punishments were carried out by parents. Additionally, children in this environment may have witnessed their parents or others close to them act out explosively or in violent manners. Observation of this type of behavior as a child makes it more likely that a person will exhibit these same traits as he or she gets older.
