Impulse control disorder in the context of "Impulsivity"

Compulsive buying disorder (CBD) is characterized by an obsession with shopping and buying behavior that causes adverse consequences. It "is experienced as a recurring, compelling and irresistible–uncontrollable urge, in acquiring goods that lack practical utility and very low cost resulting in excessive, expensive and time-consuming retail activity [that is] typically prompted by negative affectivity" and results in "gross social, personal and/or financial difficulties". Most people with CBD meet the criteria for a personality disorder. Compulsive buying can also be found among people with Parkinson's disease or frontotemporal dementia.

Compulsive buying-shopping disorder is classified by the ICD-11 among "other specified impulse control disorders". Several authors have considered compulsive shopping rather as a variety of dependence disorder. The DSM-5 did not include compulsive buying disorder in its chapter concerning substance-related and addictive disorders, since there is "still debate on whether other less recognized forms of impulsive behaviors, such as compulsive buying [...] can be conceptualized as addictions."

Arson is the act of willfully and deliberately setting fire to or charring property. Although the act of arson typically involves buildings, the term can also refer to the intentional burning of other things, such as motor vehicles, watercraft, or forests. The crime is typically classified as a felony, with instances involving risk to human life or property carrying a stricter penalty. Arson that results in death can be further prosecuted as manslaughter or murder. A common motive for arson is to commit insurance fraud. In such cases, a person destroys their own property by burning it and then lies about the cause in order to collect against their insurance policy. Arson is also often committed to conceal another crime, such as murder or burglary.

A person who commits arson is referred to as an arsonist, or a serial arsonist if the person has committed arson several times. Arsonists normally use an accelerant (such as gasoline or kerosene) to ignite, propel, and direct fires, and the detection and identification of ignitable liquid residues is an important part of fire investigations. Pyromania is an impulse control disorder characterized by the pathological setting of fires. Most acts of arson are not committed by pyromaniacs.

Body-focused repetitive behavior (BFRB) is an umbrella name for impulse-control behaviors involving compulsively damaging one's physical appearance or causing physical injury.

BFRB disorders are currently estimated to be under the obsessive–compulsive spectrum. They are also associated with attention deficit hyperactivity disorder (ADHD) and anxiety.

Nail biting, also known as onychophagy or onychophagia, is an oral compulsive habit of biting one's fingernails. It is sometimes described as a parafunctional activity, the use of the mouth for an activity other than speaking, eating, or drinking.

Nail biting is a common habit, with it being present in approximately 20-30% of the population, and that statistic only increases to ~37% when explicitly reviewing the ages three to twenty-one year-old demographic. More pathological forms of nail biting are considered impulse control disorders in the DSM-IV-R and are classified under obsessive-compulsive and related disorders in the DSM-5. The ICD-10 classifies the practice as "other specified behavioral and emotional disorders with onset usually occurring in childhood and adolescence". However, not all nail biting is pathological, and the difference between harmful obsession and normal behavior is not always clear. The earliest reference to nail biting as a symptom of anxiety was in the late sixteenth century in France.
