The Diagnostic and Statistical Manual of Mental Disorders is a publication by the American Psychiatric Association (APA) for the classification of mental disorders using a common language and standard criteria. It is the main book for the diagnosis and treatment of mental disorders in the United States and is considered one of the principal guides of psychiatry, along with the ICD, CCMD, and the Psychodynamic Diagnostic Manual. However, not all providers rely on the DSM-5 as a guide, since the ICD's mental disorder diagnoses are used around the world and scientific studies often measure changes in symptom scale scores rather than changes in DSM-5 criteria to determine the real-world effects of mental health interventions.
Narcissistic personality disorder (NPD) is a personality disorder characterized by a life-long pattern of exaggerated feelings of self-importance, an excessive need for admiration and a delusional sense of status, diminished ability or unwillingness to empathize with others' feelings, and interpersonally exploitative behavior. Narcissistic personality disorder is one of the sub-types of the broader category known as personality disorders. It is often comorbid with other mental disorders and associated with significant functional impairment and psychosocial disability.
Antisocial personality disorder is a personality disorder characterized by limited capacity for empathy and long-term pattern of disregard or violation of the rights of others. Other notable symptoms include impulsivity and reckless behavior, lack of remorse after hurting others, deceitfulness, irresponsibility, and aggressive behavior.
Hypersexuality is extremely frequent or suddenly increased libido. It is controversial whether it should be included as a clinical diagnosis used by mental healthcare professionals. Nymphomania and satyriasis were terms previously used for the condition in women and men, respectively.
In psychology, codependency is a theory that attempts to explain imbalanced relationships where one person enables another person's self-destructive behavior such as addiction, poor mental health, immaturity, irresponsibility, or under-achievement.
Obsessive–compulsive personality disorder (OCPD) is a cluster C personality disorder marked by a spectrum of obsessions with rules, lists, schedules, and order, among other things. Symptoms are usually present by the time a person reaches adulthood, and are visible in a variety of situations. The cause of OCPD is thought to involve a combination of genetic and environmental factors, namely problems with attachment.
Dissociation is a concept that has been developed over time and which concerns a wide array of experiences, ranging from a mild emotional detachment from the immediate surroundings, to a more severe disconnection from physical and emotional experiences. The major characteristic of all dissociative phenomena involves a detachment from reality, rather than a loss of reality as in psychosis.
According to proponents of the concept, sexual addiction, also known as sex addiction, is a state characterized by compulsive participation or engagement in sexual activity, particularly sexual intercourse, despite negative consequences. The concept is contentious; neither of the two major mainstream medical categorization systems recognise sex addiction as a real medical condition, instead categorizing such behavior under labels such as compulsive sexual behavior.
Dissociative disorders (DD) are conditions that involve disruptions or breakdowns of memory, awareness, identity, or perception. People with dissociative disorders use dissociation as a defense mechanism, pathologically and involuntarily. The individual experiences these dissociations to protect themselves. Some dissociative disorders are triggered by psychological trauma, but depersonalization-derealization disorder may be preceded only by stress, psychoactive substances, or no identifiable trigger at all.
Dual diagnosis is the condition of having a mental illness and a comorbid substance use disorder. There is considerable debate surrounding the appropriateness of using a single category for a heterogeneous group of individuals with complex needs and a varied range of problems. The concept can be used broadly, for example depression and alcohol use disorder, or it can be restricted to specify severe mental illness and substance use disorder, or a person who has a milder mental illness and a drug dependency, such as panic disorder or generalized anxiety disorder and is dependent on opioids. Diagnosing a primary psychiatric illness in people who use substances is challenging as substance use disorder itself often induces psychiatric symptoms, thus making it necessary to differentiate between substance induced and pre-existing mental illness.
Kenneth Blum is an American scientist who has studied neuropsychopharmacology and genetics. Until 1995 he was a professor of Pharmacology at the University of Texas Health Science Center at San Antonio.
The Spann-Fischer Codependency Scale is a 16-item self-report instrument that has been proposed as a measure of co-dependency. The scale is based upon a definition of codependency as "a dysfunctional pattern of relating to others with an extreme focus outside of oneself, lack of expression of feelings, and personal meaning derived from relationships with others." Codependency has no established definition within the mental health community, and is not a recognized diagnosis as a mental health disorder.
Behavioral 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 since the 1990s. 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 in the reward system.
Personality disorders (PD) are a class of mental disorders characterized by enduring maladaptive patterns of behavior, cognition, and inner experience, exhibited across many contexts and deviating from those accepted by the individual's culture. These patterns develop early, are inflexible, and are associated with significant distress or disability. The definitions vary by source and remain a matter of controversy. Official criteria for diagnosing personality disorders are listed in the sixth chapter of the International Classification of Diseases (ICD) and in the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders (DSM).
Substance use disorder (SUD) is the persistent use of drugs 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”. Substance use disorders (SUD) are considered to be a serious mental illness that fluctuates with the age that symptoms first start appearing in an individual, the time during which it exists and the type of substance that is used. It is not uncommon that those who have SUD also have other mental health disorders. Substance use disorders are characterized by an array of mental/emotional, physical, and behavioral problems such as chronic guilt; an inability to reduce or stop consuming the substance(s) despite repeated attempts; operating vehicles while intoxicated; and physiological withdrawal symptoms. Drug classes that are commonly involved in SUD include: alcohol, caffeine, cannabis, hallucinogens, inhalants, opioids, sedatives, hypnotics or anxiolytics, stimulants, tobacco
Compulsive sexual behaviour disorder (CSBD), otherwise known as hypersexual disorder, is a pattern of behavior involving intense preoccupation with sexual fantasies and behaviours that cause significant levels of psychological distress, are inappropriately used to cope with stress, cannot be voluntarily curtailed, and risk or cause harm to oneself or others. This disorder can also cause impairment in social, occupational, personal, or other important functions.
A psychoactive drug, psychopharmaceutical, psychoactive agent, or psychotropic drug is a chemical substance that changes the function of the nervous system and results in alterations of perception, mood, cognition, and behavior. These substances may be used medically, recreationally, for spiritual reasons, or for research. Some categories of psychoactive drugs may be prescribed by physicians and other healthcare practitioners because of their therapeutic value.
Joanna Moncrieff is a British psychiatrist and academic. She is Professor of Critical and Social Psychiatry at University College London and a leading figure in the Critical Psychiatry Network. She is a prominent critic of the modern 'psychopharmacological' model of mental disorder and drug treatment, and the role of the pharmaceutical industry. She has written papers, books and blogs on the use and over-use of drug treatment for mental health problems, the mechanism of action of psychiatric drugs, their subjective and psychoactive effects, the history of drug treatment, and the evidence for its benefits and harms. She also writes on the history and politics of psychiatry more generally. Her best known books are The Myth of the Chemical Cure and The Bitterest Pills.
Stimulant use disorder is a type of substance use disorder where the use of stimulants caused clinically significant impairment or distress. It is defined in the DSM-5 as "the continued use of amphetamine-type substances, cocaine, or other stimulants leading to clinically significant impairment or distress, from mild to severe". These psychoactive drugs, known as stimulants, are among the most widely used drugs in the world today, although not all stimulants can induce addiction. As of 1993, Approximately 200 million Americans have used some type of stimulant in the past year alone.
