Eysenck and Eysenck related impulsivity to risk-taking, lack of planning, and making up one's mind quickly. Impulsivity has been shown to be a major component of various neuropsychiatric disorders such as ADHD, substance abuse disorders and bipolar disorder. Impulsivity has been shown to have a genetic component and may be inheritable. Abnormal patterns of impulsivity may also be an acquired trait as a result of various neurodegenerative diseases, traumatic brain injury (TBI), hypoxic ischemic encephalopathy, intrauterine hypoxia, bacterial or viral infections or neurotoxicity as a result of chemical exposure. The orbitofrontal cortex and right inferior frontal gyrus have been shown to play a part in impulse control.
