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.
Dissociative fugue, formerly called a fugue state or psychogenic fugue, is a mental and behavioral disorder that is classified variously as a dissociative disorder, a conversion disorder, and a somatic symptom disorder. The disorder is a rare psychiatric abnormality characterized by reversible amnesia for one's own personal identity, including the memories, personality, and other identifying characteristics of individuality. The state can last days, months or longer. Dissociative fugue usually involves unplanned travel or wandering and is sometimes accompanied by the establishment of a new identity. It is a facet of dissociative amnesia, according to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5).
Dissociative identity disorder (DID), previously known as multiple personality disorder (MPD), is a mental disorder characterized by the maintenance of at least two distinct and relatively enduring personality states. The disorder is accompanied by memory gaps beyond what would be explained by ordinary memory issues. The personality states alternately show in a person's behavior; however, presentations of the disorder vary. Other conditions that often occur in people with DID include post-traumatic stress disorder, personality disorders, depression, substance use disorders, conversion disorder, somatic symptom disorder, eating disorders, obsessive–compulsive disorder, and sleep disorders. Self-harm, non-epileptic seizures, flashbacks with amnesia for content of flashbacks, anxiety disorders, and suicidality are also common.
Schizoaffective disorder is a mental disorder characterized by abnormal thought processes and an unstable mood. The diagnosis is made when the person has symptoms of both schizophrenia and a mood disorder—either bipolar disorder or depression. The main criterion for a diagnosis of schizoaffective disorder is the presence of psychotic symptoms for at least two weeks without any mood symptoms present. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, psychotic bipolar disorder, schizophreniform disorder, or schizophrenia. It is imperative for providers to accurately diagnose patients, as treatment and prognosis differ greatly for each of these diagnoses.
Dissociation, as a concept that has been developed over time, is any of 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.
Depersonalization-derealization disorder is a mental disorder in which the person has persistent or recurrent feelings of depersonalization or derealization. Depersonalization is described as feeling disconnected or detached from one's self. Individuals may report feeling as if they are an outside observer of their own thoughts or body, and often report feeling a loss of control over their thoughts or actions. Derealization is described as detachment from one's surroundings. Individuals experiencing derealization may report perceiving the world around them as foggy, dreamlike/surreal, or visually distorted.
Intermittent explosive disorder is a behavioral disorder characterized by explosive outbursts of anger and/or violence, often to the point of rage, that are disproportionate to the situation at hand. Impulsive aggression is not premeditated, and is defined by a disproportionate reaction to any provocation, real or perceived. Some individuals have reported affective changes prior to an outburst, such as tension, mood changes, energy changes, etc.
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 suffers 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.
Robert Leopold Spitzer was a psychiatrist and professor of psychiatry at Columbia University in New York City. He was a major force in the development of the Diagnostic and Statistical Manual of Mental Disorders (DSM).
The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), is the 2013 update to the Diagnostic and Statistical Manual of Mental Disorders, the taxonomic and diagnostic tool published by the American Psychiatric Association (APA). In the United States, the DSM serves as the principal authority for psychiatric diagnoses. Treatment recommendations, as well as payment by health care providers, are often determined by DSM classifications, so the appearance of a new version has practical importance. The DSM-5 is the only DSM to use an Arabic numeral instead of a Roman numeral in its title, as well as the only living document version of a DSM.
Marlene Steinberg M.D, is a researcher on Dissociation symptoms and disorders. She developed the pioneering: The Structured Clinical Interview for DSM-IV Dissociative Disorders (SCID-D) and wrote in conjunction with Maxine Schnall, The Stranger In The Mirror Dissociation - The Hidden Epidemic.
The Schedule for Affective Disorders and Schizophrenia (SADS) is a collection of psychiatric diagnostic criteria and symptom rating scales originally published in 1978. It is organized as a semi-structured diagnostic interview. The structured aspect is that every interview asks screening questions about the same set of disorders regardless of the presenting problem; and positive screens get explored with a consistent set of symptoms. These features increase the sensitivity of the interview and the inter-rater reliability of the resulting diagnoses. The SADS also allows more flexibility than fully structured interviews: Interviewers can use their own words and rephrase questions, and some clinical judgment is used to score responses. There are three versions of the schedule, the regular SADS, the lifetime version (SADS-L) and a version for measuring the change in symptomology (SADS-C). Although largely replaced by more structured interviews that follow diagnostic criteria such as DSM-IV and DSM-5, and specific mood rating scales, versions of the SADS are still used in some research papers today.
The Eating Disorder Diagnostic Scale (EDDS) is a 22 item self-report questionnaire that assesses the presence of three eating disorders; anorexia nervosa, bulimia nervosa and binge eating disorder. It was adapted by Stice et al. in 2000 from the validated structured psychiatric interview: The Eating Disorder Examination (EDE) and the eating disorder module of the Structured Clinical Interview for DSM-IV (SCID)16.
Michael B. First is an American psychiatrist who focuses on diagnostic criteria for mental disorders. He is Professor of Clinical Psychiatry at Columbia University. First was one of the editors of DSM-IV-TR, the Editor of Text and Criteria for the DSM-IV, and the editor of the Structured Clinical Interview for DSM-IV. He also served as consultant to the World Health Organization for the revision of ICD-11.
A somatic symptom disorder, formerly known as a somatoform disorder, is any mental disorder that manifests as physical symptoms that suggest illness or injury, but cannot be explained fully by a general medical condition or by the direct effect of a substance, and are not attributable to another mental disorder. Somatic symptom disorders, as a group, are included in a number of diagnostic schemes of mental illness, including the Diagnostic and Statistical Manual of Mental Disorders.
The Patient Health Questionnaire (PHQ) is a multiple-choice self-report inventory that is used as a screening and diagnostic tool for mental health disorders of depression, anxiety, alcohol, eating, and somatoform disorders. It is the self-report version of the Primary Care Evaluation of Mental Disorders (PRIME-MD), a diagnostic tool developed in the mid-1990s by Pfizer Inc. The length of the original assessment limited its feasibility; consequently, a shorter version, consisting of 11 multi-part questions - the Patient Health Questionnaire was developed and validated.
The 9-question Patient Health Questionnaire (PHQ-9) is a diagnostic tool introduced in 2001 to screen adult patients in a primary care setting for the presence and severity of depression. The PHQ-9 is the self-administered depression scale from the Patient Health Questionnaire (PHQ). The PHQ is part of Pfizer's larger suite of trademarked products, called the Primary Care Evaluation of Mental Disorders (PRIME-MD). The PHQ-9 takes less than 3 minutes to complete and simply scores each of the 9 DSM-IV criteria for depression based on the mood module from the original PRIME-MD. Primary care providers frequently use the PHQ-9 to screen for depression in patients.
Janet B. W. Williams is an American social worker who focuses on the diagnosis and assessment of mental disorders. She is Professor Emerita of Clinical Psychiatric Social Work at Columbia University. She was a major force in writing the PHQ-9, a 9-question instrument given to patients in a primary care setting to screen for the presence and severity of depression.
The NetSCID-5 is an online version of the Structured Clinical Interview for DSM-5, developed and marketed in consultation with the SCID-5 authors by TeleSage, Inc. in Chapel Hill, North Carolina..
