Diagnostic models do not currently include the criteria necessary to identify behaviors as addictions in a clinical setting. Behavioral addictions have been proposed as a new class in ''[[DSM-5]]'', but the only category included is gambling addiction.

Similar to the changes in ''[[DSM-5]], the eleventh revision of the [[International Classification of Diseases]] ([[ICD-11]])'' introduced the category "Disorders due to substance use or addictive behaviours" based on the diagnostic framework of impaired control, repetitive harmful behavior, and continuation or escalation despite negative consequences<ref name=":1">{{Cite journal |last=Stein |first=Dan J. |last2=Szatmari |first2=Peter |last3=Gaebel |first3=Wolfgang |last4=Berk |first4=Michael |last5=Vieta |first5=Eduard |last6=Maj |first6=Mario |last7=de Vries |first7=Ymkje Anna |last8=Roest |first8=Annelieke M. |last9=de Jonge |first9=Peter |last10=Maercker |first10=Andreas |last11=Brewin |first11=Chris R. |last12=Pike |first12=Kathleen M. |last13=Grilo |first13=Carlos M. |last14=Fineberg |first14=Naomi A. |last15=Briken |first15=Peer |date=27 January 2020 |title=Mental, behavioral and neurodevelopmental disorders in the ICD-11: an international perspective on key changes and controversies |url=https://bmcmedicine.biomedcentral.com/articles/10.1186/s12916-020-1495-2 |journal=BMC Medicine |language=en |volume=18 |issue=1 |doi=10.1186/s12916-020-1495-2 |issn=1741-7015 |pmc=PMC6983973 |pmid=31983345}}</ref>.

Behavioral addictions, which are sometimes referred to as impulse control disorders, are increasingly recognized as treatable forms of addiction.<ref>Grant, Jon: Impulse Control Disorders: A Clinician's Guide to Understanding and Treating Behavioral Addictions</ref>
The type of excessive behaviors identified as being addictive include [[Problem gambling|gambling]], [[eating disorder|eating]], having [[sexual addiction|sexual intercourse]], using [[pornography addiction|pornography]], [[computer addiction|computers]], [[Video game addiction|video games]], [[Internet addiction disorder|internet]] and [[Digital media use and mental health|digital media]], [[Physical exercise#Excessive exercise|physical exercise]], and [[Compulsive buying disorder|shopping]].


In August 2011, the [[American Society of Addiction Medicine]] (ASAM) issued a public statement defining all addiction in terms of brain changes. "Addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry."<ref>American Society of Addiction Medicine.

In 2019, the [[American Society of Addiction Medicine]] (ASAM) revised its definition of addiction including substance use and compulsive behaviors - "addiction is a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment, and an individual’s life experiences".<ref>{{Cite web |date=15 September 2019 |title=What is the Definition of Addiction? |url=https://www.asam.org/quality-care/definition-of-addiction |archive-url=https://www.asam.org/docs/default-source/quality-science/asam's-2019-definition-of-addiction-(1).pdf?sfvrsn=b8b64fc2_2 |archive-date=15 September 2019 |access-date=2023-10-05 |website=[[American Society of Addiction Medicine]] |language=en}}</ref>

The following excerpts are taken from the organization's FAQs: {{blockquote|The new ASAM definition makes a departure from equating addiction with just [[substance dependence]], by describing how addiction is also related to behaviors that are rewarding. This is the first time that ASAM has taken an official position that addiction is not solely "substance dependence." This definition says that addiction is about functioning and brain circuitry and how the structure and function of the brains of persons with addiction differ from the structure and function of the brains of persons who do not have addiction. It talks about reward circuitry in the brain and related circuitry, but the emphasis is not on the external rewards that act on the reward system. [[Food and sexuality|Food and sexual]] behaviors and gambling behaviors can be associated with the "pathological pursuit of rewards" described in this new definition of addiction. }}

{{blockquote|We all have the brain reward circuitry that makes food and sex rewarding. In fact, this is a survival mechanism. In a healthy brain, these rewards have feedback mechanisms for satiety or 'enough.' In someone with addiction, the circuitry becomes dysfunctional such that the message to the individual becomes 'more', which leads to the pathological pursuit of rewards and/or relief through the use of substances and behaviors. So, anyone who has addiction is vulnerable to food and sex addiction.}}

Meanwhile, ''DSM-5'' has deprecated the term "addiction".<ref>{{Cite book|last=American Psychiatric Association|year=2013|title=Diagnostic and Statistical Manual of Mental Disorders| edition=Fifth |publisher=American Psychiatric Publishing|location=Arlington, VA|pages=485|isbn=978-0-89042-555-8|quote=Note that the word ''addiction'' is not applied as a diagnostic term in this classification, although it is in common usage in many countries to describe severe problems related to compulsive and habitual use of substances.}}</ref>


==Treatment==
==Treatment==


Behavioral addiction is a treatable condition. Treatment options include [[psychotherapy]] and [[psychopharmacology|psychopharmacotherapy]] (i.e., medications) or a combination of both. [[Cognitive behavioral therapy]] (CBT) is the most common form of psychotherapy used in treating behavioral addictions; it focuses on identifying patterns that trigger [[compulsive behavior]] and making lifestyle changes to promote healthier behaviors. Because cognitive behavioral therapy is considered a short term therapy, the number of sessions for treatment normally ranges from five to twenty. During the session, therapists will lead patients through the topics of identifying the issue, becoming aware of one's thoughts surrounding the issue, identifying any negative or false thinking, and reshaping said negative and false thinking. While CBT does not cure behavioral addiction, it does help with coping with the condition in a healthy way. Currently, there are no medications approved for treatment of behavioral addictions in general, but some medications used for treatment of drug addiction may also be beneficial with specific behavioral addictions.<ref name="Behavioral addictions">{{cite journal | vauthors = Grant JE, Potenza MN, Weinstein A, Gorelick DA | title = Introduction to behavioral addictions | journal = Am.

Revision as of 18:10, 5 October 2023

Behavioral addiction, process addiction[1], or non-substance-related disorder[2] is a form of addiction that involves a compulsion to engage in a rewarding non-substance-related behavior – sometimes called a natural reward[3][4] – despite any negative consequences to the person's physical, mental, social or financial well-being.[5] In the brain's reward system, a gene transcription factor known as ΔFosB has been identified as a necessary common factor involved in both behavioral and drug addictions, which are associated with the same set of neural adaptations.[3][4][6]

Addiction canonically refers to substance abuse; however, the term's connotation has been expanded to include behaviors that may lead to a reward (such as gambling, eating, or shopping)[7] since the 1990s. Still, the framework to diagnose and categorize behavioral addiction is a controversial topic in the psychopathology field[8][9].

Psychiatric and medical classifications

Diagnostic and Statistical Manual of Mental Disorders (DSM) recognized behavioral addictions for the first time in DSM-5 with gambling disorder, formerly pathological gambling, as the only non-substance-related disorder classified under the chapter of "Substance-Related and Addictive Disorders"[10]. Internet gaming addiction was included in the appendix as a condition for further study.[11] Although "addiction" is commonly used to describe repetitive harmful behavior in nonmedical settings[12], DSM-5 recommended the neutral term "disorder" instead of "addiction" under the clinical settings to avoid uncertain definition and potentially negative connotation[13].

Similar to the changes in DSM-5, the eleventh revision of the International Classification of Diseases (ICD-11) introduced the category "Disorders due to substance use or addictive behaviours" based on the diagnostic framework of impaired control, repetitive harmful behavior, and continuation or escalation despite negative consequences[14]. The new sub-category "Disorders due to addictive behaviours" included gambling disorder (formerly under the habit and impulse disorders), gaming disorder (a new diagnosis), and two residual categories (other specified and unspecified) to raise attention among clinicians and the public and to facilitate further research[14][15].

In 2019, the American Society of Addiction Medicine (ASAM) revised its definition of addiction including substance use and compulsive behaviors - "addiction is a treatable, chronic medical disease involving complex interactions among brain circuits, genetics, the environment, and an individual’s life experiences".[16]

Other addictive behaviors which have received research attention but with insufficient or inconclusive evidence include pornography use disorder, compulsive buying disorder, social network use disorder, work addiction, exercise addiction, compulsive sexual behavior disorder, and food addiction[13][17][18][19].

Treatment

Behavioral addiction is a treatable condition {{Citation needed}}. Treatment options include psychotherapy and psychopharmacotherapy (i.e., medications) or a combination of both. Cognitive behavioral therapy (CBT) is the most common form of psychotherapy used in treating behavioral addictions; it focuses on identifying patterns that trigger compulsive behavior and making lifestyle changes to promote healthier behaviors. Because cognitive behavioral therapy is considered a short-term therapy, the number of sessions for treatment normally ranges from five to twenty {{Citation needed}}. During the session, therapists will lead patients through the topics of identifying the issue, becoming aware of one's thoughts surrounding the issue, identifying any negative or false thinking, and reshaping said negative and false thinking. While CBT does not cure behavioral addiction, it does help with coping with the condition in a healthy way. Currently, there are no medications approved for treatment of behavioral addictions in general, but some medications used for treatment of drug addiction may also be beneficial with specific behavioral addictions.[20]

Research

A recent narrative review[21] in 2017 examined the existing literature for studies reporting associations between behavioral addictions (pathological gambling, problematic internet use, problematic online gaming, compulsive sexual behavior disorder, compulsive buying and exercise addiction) and psychiatric disorders. Overall, there is solid evidence for associations between behavioral addictions and mood disorder, anxiety disorder as well as substance use disorders. Associations between ADHD may be specific to problematic internet use and problematic online gaming. The authors also conclude that most of current research on the association between behavioral addictions and psychiatric disorders has several limitations: they are mostly cross-sectional, are not from representative samples, and are often based on small samples, among others. Especially more longitudinal studies are needed to establish the direction of causation, i.e. whether behavioral addictions are a cause or a consequence of psychiatric disorders.

Biomolecular mechanisms

Main article: ΔFosB

ΔFosB, a gene transcription factor, has been identified as playing a critical role in the development of addictive states in both behavioral addictions and drug addictions.[3][4][6] Overexpression of ΔFosB in the nucleus accumbens is necessary and sufficient for many of the neural adaptations seen in drug addiction;[3] it has been implicated in addictions to alcohol, cannabinoids, cocaine, nicotine, phenylcyclidine, and substituted amphetamines[3][22][23][24] as well as addictions to natural rewards such as sex, exercise, and food.[4][6] A recent study also demonstrated a cross-sensitization between drug reward (amphetamine) and a natural reward (sex) that was mediated by ΔFosB.[25]

Besides increased ΔFosB expression in the nucleus accumbens, there are many other correlations in the neurobiology of behavioral addictions with drug addictions.

One of the most important discoveries of addictions has been the drug based reinforcement and, even more important, reward based learning processes. Several structures of the brain are important in the conditioning process of behavioral addiction; these subcortical structures form the brain regions known as the reward system. One of the major areas of study is the amygdala, a brain structure which involves emotional significance and associated learning. Research shows that dopaminergic projections from the ventral tegmental area facilitate a motivational or learned association to a specific behavior.[26] Dopamine neurons take a role in the learning and sustaining of many acquired behaviors. Research specific to Parkinson's disease has led to identifying the intracellular signaling pathways that underlie the immediate actions of dopamine. The most common mechanism of dopamine is to create addictive properties along with certain behaviors.[27] There are three stages to the dopamine reward system: bursts of dopamine, triggering of behavior, and further impact to the behavior. Once electronically signaled, possibly through the behavior, dopamine neurons let out a 'burst-fire' of elements to stimulate areas along fast transmitting pathways. The behavior response then perpetuates the striated neurons to further send stimuli. The fast firing of dopamine neurons can be monitored over time by evaluating the amount of extracellular concentrations of dopamine through micro dialysis and brain imaging. This monitoring can lead to a model in which one can see the multiplicity of triggering over a period of time.[28] Once the behavior is triggered, it is hard to work away from the dopamine reward system.

Behaviors like gambling have been linked to the newfound idea of the brain's capacity to anticipate rewards. The reward system can be triggered by early detectors of the behavior, and trigger dopamine neurons to begin stimulating behaviors. But in some cases, it can lead to many issues due to error, or reward-prediction errors. These errors can act as teaching signals to create a complex behavior task over time.[28]

Importantly, genetic or viral overexpression of ΔJunD, a dominant negative mutant of JunD which antagonizes ΔFosB- and other AP-1-mediated transcriptional activity, in the NAc or OFC blocks these key effects of drug exposure14,22–24. This indicates that ΔFosB is both necessary and sufficient for many of the changes wrought in the brain by chronic drug exposure. ΔFosB is also induced in D1-type NAc MSNs by chronic consumption of several natural rewards, including sucrose, high fat food, sex, wheel running, where it promotes that consumption14,26–30. This implicates ΔFosB in the regulation of natural rewards under normal conditions and perhaps during pathological addictive-like states.

PMC 4040958. PMID 22641964. It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward. Pitchers and colleagues (2010) reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus. Next, the induction of c-Fos, a downstream (repressed) target of DeltaFosB, was measured in sexually experienced and naive animals. The number of mating-induced c-Fos-IR cells was significantly decreased in sexually experienced animals compared to sexually naive controls. Finally, DeltaFosB levels and its activity in the NAc were manipulated using viral-mediated gene transfer to study its potential role in mediating sexual experience and experience-induced facilitation of sexual performance. Animals with DeltaFosB overexpression displayed enhanced facilitation of sexual performance with sexual experience relative to controls. In contrast, the expression of DeltaJunD, a dominant-negative binding partner of DeltaFosB, attenuated sexual experience-induced facilitation of sexual performance, and stunted long-term maintenance of facilitation compared to DeltaFosB overexpressing group. Together, these findings support a critical role for DeltaFosB expression in the NAc in the reinforcing effects of sexual behavior and sexual experience-induced facilitation of sexual performance. ... both drug addiction and sexual addiction represent pathological forms of neuroplasticity along with the emergence of aberrant behaviors involving a cascade of neurochemical changes mainly in the brain's rewarding circuitry.
