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 Australia, while in other countries it may be used in conjunction with other documents. The DSM-5 is considered one of the principal guides of psychiatry, along with the International Classification of Diseases 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.
A mental disorder, also referred to as a mental illness, a mental health condition, or a psychiatric disorder, is a behavioral or mental pattern that causes significant distress or impairment of personal functioning. A mental disorder is also characterized by a clinically significant disturbance in an individual's cognition, emotional regulation, or behavior, often in a social context. Such disturbances may occur as single episodes, may be persistent, or may be relapsing–remitting. There are many different types of mental disorders, with signs and symptoms that vary widely between specific disorders. A mental disorder is one aspect of mental health.
A mental disorder is an impairment of the mind disrupting normal thinking, feeling, mood, behavior, or social interactions, and accompanied by significant distress or dysfunction. The causes of mental disorders are very complex and vary depending on the particular disorder and the individual. Although the causes of most mental disorders are not fully understood, researchers have identified a variety of biological, psychological, and environmental factors that can contribute to the development or progression of mental disorders. Most mental disorders result in a combination of several different factors rather than just a single factor.
Borderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD), is a personality disorder characterized by a long-term pattern of intense and unstable interpersonal relationships, distorted sense of self, and strong emotional reactions. Those affected often engage in self-harm and other dangerous behaviors, often due to their difficulty with returning their emotional level to a healthy or normal baseline. They may also struggle with dissociation, a feeling of emptiness, and a fear of abandonment.
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. Hypochondria is an old concept whose meaning has repeatedly changed over its lifespan. It has been claimed that this debilitating condition results from an inaccurate perception of the condition of body or mind despite the absence of an actual medical diagnosis. An individual with hypochondriasis is known as a hypochondriac. Hypochondriacs become unduly alarmed about any physical or psychological symptoms they detect, no matter how minor the symptom may be, and are convinced that they have, or are about to be diagnosed with, a serious illness.
Hypersexuality is a term used for a presumed mental disorder which causes unwanted or excessive sexual arousal, causing people to engage in or think about sexual activity to a point of distress or impairment. 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.
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.
Psychopathology is the study of abnormal cognition, behaviour, and experiences which differs according to social norms and rests upon a number of constructs that are deemed to be the social norm at any particular era.
Psychological trauma is an emotional response caused by severe distressing events that are outside the normal range of human experiences, with extreme examples being violence, rape, or a terrorist attack. The event must be understood by the affected person as directly threatening the affected person or their loved ones with death, severe bodily injury, or sexual violence; indirect exposure, such as from watching television news, may be extremely distressing and can produce an involuntary and possibly overwhelming physiological stress response, but does not produce trauma per se.
The Hearing Voices Movement (HVM) is the name used by organizations and individuals advocating the "hearing voices approach", an alternative way of understanding the experience of those people who "hear voices". In the medical professional literature, ‘voices’ are most often referred to as auditory verbal hallucinations. The movement uses the term ‘hearing voices’, which it feels is a more accurate and 'user-friendly' term.
Complex post-traumatic stress disorder (CPTSD) is a stress-related mental disorder generally occurring in response to complex traumas, i.e., commonly prolonged or repetitive exposures to a series of traumatic events, within which individuals perceive little or no chance to escape.
The trauma model of mental disorders, or trauma model of psychopathology, emphasises the effects of physical, sexual and psychological trauma as key causal factors in the development of psychiatric disorders, including depression and anxiety as well as psychosis, whether the trauma is experienced in childhood or adulthood. It conceptualises people as having understandable reactions to traumatic events rather than suffering from mental illness.
Gender is correlated with the prevalence of certain mental disorders, including depression, anxiety and somatic complaints. For example, women are more likely to be diagnosed with major depression, while men are more likely to be diagnosed with substance abuse and antisocial personality disorder. There are no marked gender differences in the diagnosis rates of disorders like schizophrenia and bipolar disorder. Men are at risk to suffer from post-traumatic stress disorder (PTSD) due to past violent experiences such as accidents, wars and witnessing death, and women are diagnosed with PTSD at higher rates due to experiences with sexual assault, rape and child sexual abuse. Nonbinary or genderqueer identification describes people who do not identify as either male or female. People who identify as nonbinary or gender queer show increased risk for depression, anxiety and post-traumatic stress disorder. People who identify as transgender demonstrate increased risk for depression, anxiety, and post-traumatic stress disorder.
Psychiatric epidemiology is a field which studies the causes (etiology) of mental disorders in society, as well as conceptualization and prevalence of mental illness. It is a subfield of the more general epidemiology. It has roots in sociological studies of the early 20th century. However, while sociological exposures are still widely studied in psychiatric epidemiology, the field has since expanded to the study of a wide area of environmental risk factors, such as major life events, as well as genetic exposures. Increasingly neuroscientific techniques like MRI are used to explore the mechanisms behind how exposures to risk factors may impact psychological problems and explore the neuroanatomical substrate underlying psychiatric disorders.
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.
Mental health literacy has been defined as "knowledge and beliefs about mental disorders which aid their recognition, management and prevention. Mental health literacy includes the ability to recognize specific disorders; knowing how to seek mental health information; knowledge of risk factors and causes, of self-treatments, and of professional help available; and attitudes that promote recognition and appropriate help-seeking". The concept of mental health literacy was derived from health literacy, which aims to increase patient knowledge about physical health, illnesses, and treatments.
A psychiatric assessment, or psychological screening, is the process of gathering information about a person within a psychiatric service, with the purpose of making a diagnosis. The assessment is usually the first stage of a treatment process, but psychiatric assessments may also be used for various legal purposes. The assessment includes social and biographical information, direct observations, and data from specific psychological tests. It is typically carried out by a psychiatrist, but it can be a multi-disciplinary process involving nurses, psychologists, occupational therapist, social workers, and licensed professional counselors.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of deleterious mental conditions. These include various matters related to mood, behaviour, cognition, and perceptions.
Ahmed Okasha is an Egyptian psychiatrist. He is a professor of psychiatry at Ain Shams University Faculty of Medicine, Cairo, Egypt. He wrote books and articles about psychiatry and mental disorders. He is the first Arab-Muslim to be president of World Psychiatric Association from 2002 to 2005.
Doctoring the Mind: Why psychiatric treatments fail is a 2009 book by Richard Bentall, his thesis is critical of contemporary Western psychiatry. Bentall, a professor of clinical psychology, argues that recent scientific research shows that the medical approach to mental illness is fatally flawed. According to Bentall, it seems there is no "evidence that psychiatry has made a positive impact on human welfare" and "patients are doing no better today than they did a hundred years ago".
