Psychosis is a condition of the mind that results in difficulties determining what is real and what is not real. Symptoms may include delusions and hallucinations, among other features. Additional symptoms are incoherent speech and behavior that is inappropriate for a given situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities. Psychosis can have serious adverse outcomes.
Schizoaffective disorder is a mental disorder characterized by abnormal thought processes and an unstable mood. This diagnosis requires symptoms of both schizophrenia and a mood disorder: either bipolar disorder or depression. The main criterion is the presence of psychotic symptoms for at least two weeks without any mood symptoms. Schizoaffective disorder can often be misdiagnosed when the correct diagnosis may be psychotic depression, bipolar I disorder, schizophreniform disorder, or schizophrenia. This is a problem as treatment and prognosis differ greatly for most of these diagnoses.
A thought disorder (TD) is a disturbance in cognition which affects language, thought and communication. Psychiatric and psychological glossaries in 2015 and 2017 identified thought disorders as encompassing poverty of ideas, neologisms, paralogia, word salad, and delusions - all disturbances of thought content and form. Two specific terms have been suggested — content thought disorder (CTD) and formal thought disorder (FTD). CTD has been defined as a thought disturbance characterized by multiple fragmented delusions, and the term thought disorder is often used to refer to an FTD: a disruption of the form of thought. Also known as disorganized thinking, FTD results in disorganized speech and is recognized as a major feature of schizophrenia and other psychoses. Disorganized speech leads to an inference of disorganized thought. Thought disorders include derailment, pressured speech, poverty of speech, tangentiality, verbigeration, and thought blocking. One of the first known cases of thought disorders, or specifically OCD as we know it today, was in 1691. John Moore, who was a bishop, had a speech in front of Queen Mary II, about "religious melancholy."
Ganser syndrome is a rare dissociative disorder characterized by nonsensical or wrong answers to questions and other dissociative symptoms such as fugue, amnesia or conversion disorder, often with visual pseudohallucinations and a decreased state of consciousness. The syndrome has also been called nonsense syndrome, balderdash syndrome, syndrome of approximate answers, hysterical pseudodementia or prison psychosis.
Orthomolecular psychiatry is the use of orthomolecular medicine for mental illness. The approach uses unorthodox forms of individualized testing and diagnosis to attempt to establish an etiology for each patient's specific symptoms, and claims to tailor the treatment accordingly, using a combination of nutrients, dietary changes and medications that are claimed to enhance quality of life and functionality as well as to reduce or eliminate symptoms and the use of xenobiotic drugs. Scientific studies have shown mixed results; although there are some promising results from nutritional psychiatry, some forms of orthomolecular psychiatry are ineffective.
The Soteria model is a milieu-therapeutic approach developed to treat acute schizophrenia, usually implemented in Soteria houses.
Paraphrenia is a mental disorder characterized by an organized system of paranoid delusions with or without hallucinations and without deterioration of intellect or personality.
Oneiroid syndrome (OS) is a condition involving dream-like disturbances of one's consciousness by vivid scenic hallucinations, accompanied by catatonic symptoms (either catatonic stupor or excitement), delusions, or psychopathological experiences of a kaleidoscopic nature. The term is from Ancient Greek "ὄνειρος" (óneiros, meaning "dream") and "εἶδος" (eîdos, meaning "form, likeness"; literally dream-like / oneiric or oniric, sometimes called "nightmare-like"). It is a common complication of catatonic schizophrenia, although it can also be caused by other mental disorders. The dream-like experiences are vivid enough to seem real to the patient. OS is distinguished from delirium by the fact that the imaginative experiences of patients always have an internal projection. This syndrome is hardly mentioned in standard psychiatric textbooks, possibly because it is not listed in DSM.
David Shakow (1901–1981) was an American psychologist. He is perhaps best known for his development of the Scientist-Practitioner Model of graduate training for clinical psychologists, adopted by the American Psychological Association in 1949.
Brief psychotic disorder — according to the classifications of mental disorders DSM-IV-TR and DSM-5 — is a psychotic condition involving the sudden onset of at least one psychotic symptom lasting 1 day to 1 month, often accompanied by emotional turmoil. Remission of all symptoms is complete with patients returning to the previous level of functioning. It may follow a period of extreme stress including the loss of a loved one. Most patients with this condition under DSM-5 would be classified as having acute and transient psychotic disorders under ICD-10. Prior to DSM-IV, this condition was called "brief reactive psychosis." This condition may or may not be recurrent, and it should not be caused by another condition.
Postpartum psychosis(PPP), also known as puerperal psychosis or peripartum psychosis, involves the abrupt onset of psychotic symptoms shortly following childbirth, typically within two weeks of delivery but less than 4 weeks postpartum. PPP is a condition currently represented under "Brief Psychotic Disorder" in the Diagnostic and Statistical Manual of Mental Disorders, Volume V (DSM-V). Symptoms may include delusions, hallucinations, disorganized speech (e.g, incoherent speech), and/or abnormal motor behavior (e.g., catatonia). Other symptoms frequently associated with PPP include confusion, disorganized thought, severe difficulty sleeping, variations of mood disorders (including depression, agitation, mania, or a combination of the above), as well as cognitive features such as consciousness that comes and goes (waxing and waning) or disorientation.
Professor Helmut Beckmann was a German psychiatrist. He was one of the founders of neurodevelopmental theory of schizophrenia and biologically-based psychiatry in Germany.
John Charles Cutting is a British psychiatrist specialising in schizophrenia research. He has written a number of books, and articles and reviews in professional journals, on the subjects of psychiatry, clinical psychology, schizophrenia and the functioning of the right cerebral hemisphere of the brain.
Childhood schizophrenia is similar in characteristics of schizophrenia that develops at a later age, but has an onset before the age of 13 years, and is more difficult to diagnose. Schizophrenia is characterized by positive symptoms that can include hallucinations, delusions, and disorganized speech; negative symptoms, such as blunted affect and avolition and apathy, and a number of cognitive impairments. Differential diagnosis is problematic since several other neurodevelopmental disorders, including autism spectrum disorder, language disorder, and attention deficit hyperactivity disorder, also have signs and symptoms similar to childhood-onset schizophrenia.
Charles Macfie Campbell (1876–1943) was a psychiatrist in the United States. He was President of the American Psychiatric Association.
The Kraepelinian dichotomy is the division of the major endogenous psychoses into the disease concepts of dementia praecox, which was reformulated as schizophrenia by Eugen Bleuler by 1908, and manic-depressive psychosis, which has now been reconceived as bipolar disorder. This division was formally introduced in the sixth edition of Emil Kraepelin's psychiatric textbook Psychiatrie. Ein Lehrbuch für Studirende und Aerzte, published in 1899. It has been highly influential on modern psychiatric classification systems, the DSM and ICD, and is reflected in the taxonomic separation of schizophrenia from affective psychosis. However, there is also a diagnosis of schizoaffective disorder to cover cases that seem to show symptoms of both.
Unitary psychosis (Einheitspsychose) refers to the 19th-century belief prevalent in German psychiatry until the era of Emil Kraepelin that all forms of psychosis were surface variations of a single underlying disease process. According to this model, there were no distinct disease entities in psychiatry but only varieties of a single universal madness and the boundaries between these variants were fluid. The prevalence of the concept in Germany during the mid-19th century can be understood in terms of a general resistance to Cartesian dualism and faculty psychology as expressed in Naturphilosophie and other Romantic doctrines that emphasised the unity of body, mind and spirit.
Sex differences in schizophrenia are widely reported. Men and women exhibit different rates of incidence and prevalence, age at onset, symptom expression, course of illness, and response to treatment. Reviews of the literature suggest that understanding the implications of sex differences on schizophrenia may help inform individualized treatment and positively affect outcomes.
Eugenia Hanfmann was an American psychologist and educator who was born in Russia. Early in her career, Hanfmann was associated with Kurt Koffka and the Gestalt movement of psychology. Later she conducted research and published on schizophrenia and personality assessment. Hanfmann established a counseling service at Brandeis University and helped form its psychology department with Abraham Maslow. Hanfmann is considered to be one of the early pioneers of women in psychology.
