Obsessive–compulsive disorderObsessive–compulsive disorder (OCD) is a mental and behavioral disorder in which an individual has intrusive thoughts (an obsession) and feels the need to perform certain routines (compulsions) repeatedly to relieve the distress caused by the obsession, to the extent where it impairs general function. Obsessions are persistent unwanted thoughts, mental images, or urges that generate feelings of anxiety, disgust, or discomfort.
Problem gamblingProblem gambling or ludomania is repetitive gambling behavior despite harm and negative consequences. Problem gambling may be diagnosed as a mental disorder according to DSM-5 if certain diagnostic criteria are met. Pathological gambling is a common disorder associated with social and family costs. The DSM-5 has re-classified the condition as an addictive disorder, with those affected exhibiting many similarities to those with substance addictions. The term gambling addiction has long been used in the recovery movement.
AddictionAddiction is generally a neuropsychological disorder defining pervasive and intense urge to engage in maladaptive behaviors providing immediate sensory rewards (e.g. consuming drugs, excessively gambling), despite their harmful consequences. Dependence is generally an addiction that can involve withdrawal issues. Addictive disorder is a category of mental disorders defining important intensities of addictions or dependences, which induce functional disabilities. There are no agreed definitions on these terms – see section on 'definitions'.
Behavioral addictionBehavioral addiction is a form of addiction that involves a compulsion to engage in a rewarding non-substance-related behavior – sometimes called a natural reward – despite any negative consequences to the person's physical, mental, social or financial well-being. 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) since the 1990s.
Autism spectrumAutism, formally called autism spectrum disorder (ASD) or autism spectrum condition (ASC), is a neurodevelopmental disorder characterized by deficits in social communication and social interaction, and repetitive or restricted patterns of behaviors, interests, or activities, which can include hyper- and hyporeactivity to sensory input. Autism is a spectrum disorder, meaning that it can manifest very differently in each person. For example, some are nonspeaking, while others have proficient spoken language.
Excoriation disorderExcoriation disorder, more commonly known as dermatillomania, is a mental disorder on the obsessive–compulsive spectrum that is characterized by the repeated urge or impulse to pick at one's own skin, to the extent that either psychological or physical damage is caused. Episodes of skin picking are often preceded or accompanied by tension, anxiety, or stress. In some cases, following picking, the affected person may feel depressed.
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.
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.
