Cognitive Relaxation and Coping Skills Therapy (CRCST) has shown preliminary success in both group and individual settings compared to waitlist control groups. This therapy consists of 12 sessions, the first three focusing on relaxation training, then cognitive restructuring, then exposure therapy. The final sessions focus on resisting aggressive impulses and other preventative measures.In France, antipsychotics such as cyamemazine, levomepromazine and loxapine are sometimes used.Tricyclic antidepressants and selective serotonin reuptake inhibitors (SSRIs, including fluoxetine, fluvoxamine, and sertraline) appear to alleviate some pathopsychological symptoms. GABAergic mood stabilizers and anticonvulsive drugs such as gabapentin, lithium, carbamazepine, and divalproex seem to aid in controlling the incidence of outbursts. Anxiolytics help alleviate tension and may help reduce explosive outbursts by increasing the provocative stimulus tolerance threshold, and are especially indicated in patients with comorbid obsessive-compulsive or other anxiety disorders. However, certain anxiolytics are known to increase anger and irritability in some individuals, especially benzodiazepines. Epidemiology
Two epidemiological studies of community samples approximated the lifetime prevalence of IED to be 4–6%, depending on the criteria set used. A Ukrainian study found comparable rates of lifetime IED (4.2%), suggesting that a lifetime prevalence of IED of 4–6% is not limited to American samples. One-month and one-year point prevalences of IED in these studies were reported as 2.0% and 2.7%, respectively. Extrapolating to the national level, 16.2 million Americans would have IED during their lifetimes and as many as 10.5 million in any year and 6 million in any month.
DSM-IV diagnosis
The past DSM-IV criteria for IED were similar to the current criteria, however, verbal aggression was not considered as part of the diagnostic criteria. The DSM-IV diagnosis was characterized by the occurrence of discrete episodes of failure to resist aggressive impulses that result in violent assault or destruction of property. Additionally, the degree of aggressiveness expressed during an episode should be grossly disproportionate to provocation or precipitating psychosocial stressor, and, as previously stated, diagnosis is made when certain other mental disorders have been ruled out, e.g., a head injury, Alzheimers disease, etc., or due to substance use or medication. Diagnosis is made using a psychiatric interview to affective and behavioral symptoms to the criteria listed in the DSM-IV.The DSM-IV-TR was very specific in its definition of Intermittent Explosive Disorder which was defined, essentially, by the exclusion of other conditions. The diagnosis required:

several episodes of impulsive behavior that result in serious damage to either persons or property, wherein
the degree of the aggressiveness is grossly disproportionate to the circumstances or provocation, and
the episodic violence cannot be better accounted for by another mental or physical medical condition. Differential diagnosis
Many psychiatric disorders and some substance use disorders are associated with increased aggression and are frequently comorbid with IED, often making differential diagnosis difficult. Individuals with IED are, on average, four times more likely to develop depression or anxiety disorders, and three times more likely to develop substance use disorders.
