Intermittent Explosive Disorder (IED) is characterized by difficulty controlling aggressive impulses which lead to behavioral outbursts which can be in the form of verbal aggression (e.g., temper tantrums, frequent elevated arguments) or behavioral aggression (e.g., damage to property or physical assault to individuals and/or animals). Outbursts are recurrent, out of proportion to the magnitude of the stressor, cause impairments in functioning, and are not pre-meditated.
