Self-administrationSelf-administration is, in its medical sense, the process of a subject administering a pharmacological substance to themself. A clinical example of this is the subcutaneous "self-injection" of insulin by a diabetic patient. In animal experimentation, self-administration is a form of operant conditioning where the reward is a drug. This drug can be administered remotely through an implanted intravenous line or an intracerebroventricular injection.
Video game addictionVideo game addiction (VGA), also known as gaming disorder or internet gaming disorder, is generally defined as a psychological addiction that is problematic, compulsive use of video games that results in significant impairment to an individual's ability to function in various life domains over a prolonged period of time. This and associated concepts have been the subject of considerable research, debate, and discussion among experts in several disciplines and has generated controversy within the medical, scientific, and gaming communities.
MotivationMotivation is the reason for which humans and other animals initiate, continue, or terminate a behavior at a given time. Motivational states are commonly understood as forces acting within the agent that create a disposition to engage in goal-directed behavior. It is often held that different mental states compete with each other and that only the strongest state determines behavior. This means that we can be motivated to do something without actually doing it. The paradigmatic mental state providing motivation is desire.
OpiateAn opiate, in classical pharmacology, is a substance derived from opium. In more modern usage, the term opioid is used to designate all substances, both natural and synthetic, that bind to opioid receptors in the brain (including antagonists). Opiates are alkaloid compounds naturally found in the opium poppy plant Papaver somniferum. The psychoactive compounds found in the opium plant include morphine, codeine, and thebaine. Opiates have long been used for a variety of medical conditions with evidence of opiate trade and use for pain relief as early as the eighth century AD.
Substance use disorderSubstance use disorder (SUD) is the persistent use of drugs (including alcohol) despite substantial harm and adverse consequences as a result of their use. The National Institute of Mental Health (NIMH) states that “Substance use disorder (SUD) is a treatable mental disorder that affects a person's brain and behavior, leading to their inability to control their use of substances like legal or illegal drugs, alcohol, or medications. Symptoms can be moderate to severe, with addiction being the most severe form of SUD”.
Addictive personalityAn addictive personality refers to a hypothesized set of personality traits that make an individual predisposed to developing addictions. This hypothesis states that there may be common personality traits observable in people suffering from addiction; however, the lack of a universally agreed upon definition has marked the research surrounding addictive personality. Addiction is a fairly broad term; it is most often associated with substance use disorders, but it can also be extended to cover a number of other compulsive behaviors, including sex, internet, television, gambling, food, and shopping.
Twelve-step programTwelve-step programs are international mutual aid programs supporting recovery from substance addictions, behavioral addictions and compulsions. Developed in the 1930s, the first twelve-step program, Alcoholics Anonymous (AA), founded by Bill Wilson and Bob Smith, aided its membership to overcome alcoholism. Since that time dozens of other organizations have been derived from AA's approach to address problems as varied as drug addiction, compulsive gambling, sex, and overeating.
Pornography addictionPornography addiction is the scientifically controversial application of an addiction model to the use of pornography. Pornography may be part of compulsive sexual behavior with negative consequences to one's physical, mental, social, or financial well-being. While the World Health Organization's ICD-11 (2022) has recognized compulsive sexual behaviour disorder (CSBD) as an "impulsive control disorder", CSBD is not an addiction, and the American Psychiatric Association's DSM-5 (2013) and the DSM-5-TR (2022) do not classify compulsive pornography consumption as a mental disorder or a behavioral addiction.
Social neuroscienceSocial neuroscience is an interdisciplinary field devoted to understanding the relationship between social experiences and biological systems. Humans are fundamentally a social species, rather than solitary. As such, Homo sapiens create emergent organizations beyond the individual—structures that range from dyads, families, and groups to cities, civilizations, and cultures. In this regard, studies indicate that various social influences, including life events, poverty, unemployment and loneliness can influence health related biomarkers.
AcamprosateAcamprosate, sold under the brand name Campral, is a medication used along with counseling to treat alcohol use disorder. Acamprosate is thought to stabilize chemical signaling in the brain that would otherwise be disrupted by alcohol withdrawal. When used alone, acamprosate is not an effective therapy for alcohol use disorder in most individuals; studies have found that acamprosate works best when used in combination with psychosocial support since the drug facilitates a reduction in alcohol consumption as well as full abstinence.
Prescription drugA prescription drug (also prescription medication, prescription medicine or prescription-only medication) is a pharmaceutical drug that is permitted to be dispensed only to those with a medical prescription. In contrast, over-the-counter drugs can be obtained without a prescription. The reason for this difference in substance control is the potential scope of misuse, from drug abuse to practicing medicine without a license and without sufficient education. Different jurisdictions have different definitions of what constitutes a prescription drug.
