Disruptive, impulse-control and conduct disorders
Intermittent Explosive Disorder
Intermittent explosive disorder involves recurrent, impulsive outbursts of verbal or physical aggression that are grossly disproportionate to the trigger and cause distress or serious consequences.
A clinical pattern, not an excuse for abuse
The outbursts are not planned and are not carried out for money, power or another tangible goal. They may be brief yet leave injury, damage, fear, guilt, relationship disruption or legal and work consequences.
Responsibility for safe behaviour remains. The diagnosis does not describe every act of violence, ordinary anger or a person’s character. Persistent angry mood between episodes, coercive control and deliberate intimidation can point to a different formulation and must not be minimised.
Diagnostic pattern
- One route involves verbal or non-injuring physical aggression about twice weekly for three months; another involves three destructive or injuring episodes within twelve months.
- Aggression is grossly disproportionate, impulsive or anger-driven, not premeditated or used to achieve a tangible objective.
- Outbursts cause distress, relationship or work impairment, or financial or legal consequences; age is at least six or developmentally equivalent.
- Bipolar episodes, DMDD, conduct and personality disorders, PTSD, neurological conditions, substances and medicines are assessed as alternative or coexisting explanations.
Treatment and accountability
A safety plan identifies early warning signs, steps away from escalation and restricts access to weapons or other dangerous means. Structured CBT may work on hostile interpretations, emotional arousal, communication and problem solving.
Anger-management strategies and alternative behaviours are tracked through frequency, severity, damage and relationship repair. A psychiatrist may consider medication individually. Substance use, ADHD and mood or trauma-related conditions receive their own treatment, while people affected by aggression also need support.
When urgent help is needed
Seek assessment when outbursts recur, create fear, injury or damage, or the person worries they will lose control. Specific threats, access to a weapon, strangulation, confinement or inability to leave safely is an emergency—do not attempt confrontation.
