Positive And Negative Syndrome Scale
The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity of patients with schizophrenia. It was published in 1987 by Stanley Kay, Lewis Opler, and Abraham Fiszbein. It is widely used in the study of antipsychotic therapy. The scale is known as the "gold standard" that all assessments of psychotic behavioral disorders should follow. The name refers to the two types of symptoms in schizophrenia, as defined by the American Psychiatric Association: positive symptoms, which refer to an excess or distortion of normal functions (e.g., hallucinations and delusions), and negative symptoms, which represent a diminution or loss of normal functions. Some of these functions which may be lost include normal thoughts, actions, ability to tell fantasies from reality, and the ability to properly express emotions. The PANSS is a relatively brief interview, requiring 45 to 50 minutes to administer. The interviewer must be trained to a standardized level ...

Schizophrenia
Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, decreased emotional expression, and apathy. Symptoms typically develop gradually, begin during young adulthood, and in many cases never become resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months (DSM-5) or one month (ICD-11). Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder. About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime. In 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipsychotic
Antipsychotics, also known as neuroleptics, are a class of Psychiatric medication, psychotropic medication primarily used to manage psychosis (including delusions, hallucinations, paranoia or disordered thought), principally in schizophrenia but also in a range of other psychotic disorders. They are also the mainstay together with mood stabilizers in the treatment of bipolar disorder. Prior research has shown that use of any antipsychotic is associated with smaller brain tissue volumes, including white matter reduction and that this brain shrinkage is dose dependent and time dependent. A more recent controlled trial suggests that second generation antipsychotics combined with intensive psychosocial therapy may potentially prevent pallidal brain volume loss in first episode psychosis. The use of antipsychotics may result in many unwanted side effects such as Extrapyramidal symptoms, involuntary movement disorders, gynecomastia, impotence, weight gain and metabolic syndrome. ...

American Psychiatric Association
The American Psychiatric Association (APA) is the main professional organization of psychiatrists and trainee psychiatrists in the United States, and the largest psychiatric organization in the world. It has more than 37,000 members are involved in psychiatric practice, research, and academia representing a diverse population of patients in more than 100 countries. The association publishes various journals and pamphlets, as well as the ''Diagnostic and Statistical Manual of Mental Disorders'' (DSM). The DSM codifies psychiatric conditions and is used mostly in the United States as a guide for diagnosing mental disorders. The organization has its headquarters in Washington, DC. History At a meeting in 1844 in Philadelphia, thirteen superintendents and organizers of insane asylums and hospitals formed the Association of Medical Superintendents of American Institutions for the Insane (AMSAII). The group included Thomas Kirkbride, creator of the asylum model which was used thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hallucination
A hallucination is a perception in the absence of an external stimulus that has the qualities of a real perception. Hallucinations are vivid, substantial, and are perceived to be located in external objective space. Hallucination is a combination of 2 conscious states of brain wakefulness and REM sleep. They are distinguishable from several related phenomena, such as dreaming ( REM sleep), which does not involve wakefulness; pseudohallucination, which does not mimic real perception, and is accurately perceived as unreal; illusion, which involves distorted or misinterpreted real perception; and mental imagery, which does not mimic real perception, and is under voluntary control. Hallucinations also differ from "delusional perceptions", in which a correctly sensed and interpreted stimulus (i.e., a real perception) is given some additional significance. Many hallucinations happen also during sleep paralyses. Hallucinations can occur in any sensory modality—visual, auditory, olfa ...

Delusion
A delusion is a false fixed belief that is not amenable to change in light of conflicting evidence. As a pathology, it is distinct from a belief based on false or incomplete information, confabulation, dogma, illusion, hallucination, or some other misleading effects of perception, as individuals with those beliefs ''are'' able to change or readjust their beliefs upon reviewing the evidence. However: "The distinction between a delusion and a strongly held idea is sometimes difficult to make and depends in part on the degree of conviction with which the belief is held despite clear or reasonable contradictory evidence regarding its veracity." Delusions have been found to occur in the context of many pathological states (both general physical and mental) and are of particular diagnostic importance in psychosis, psychotic disorders including schizophrenia, paraphrenia, Mania, manic episodes of bipolar disorder, and psychotic depression. Types Delusions are categorized into four d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Negative Symptom
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include hypertension, elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait (human), gait, and Arcus senilis, arcus senilis and ...

Social Withdrawal
Solitude is a state of seclusion or isolation, meaning lack of socialisation. Effects can be either positive or negative, depending on the situation. Short-term solitude is often valued as a time when one may work, think, or rest without disturbance. It may be desired for the sake of privacy. Undesirable long-term solitude may stem from soured relationships, loss of loved ones, deliberate choice, infectious disease, mental disorders, neurological disorders such as circadian rhythm sleep disorder, or circumstances of employment or situation. A distinction has been made between solitude and loneliness. In this sense, these two words refer, respectively, to the joy and the pain of being alone. Health effects Symptoms from complete isolation, called sensory deprivation, may include anxiety, sensory illusions, or distortions of time and perception. However, this is the case when there is no stimulation of the sensory systems at all and not just lack of contact with people. Thus, ...

Brief Psychiatric Rating Scale
The Brief Psychiatric Rating Scale (BPRS) is a rating scale which a clinician or researcher may use to measure psychiatric symptoms such as depression, anxiety, hallucinations and unusual behaviour. The scale is one of the oldest, most widely used scales to measure psychotic symptoms and was first published in 1962.Overall JE, Gorham DR (1962). The brief psychiatric rating scale. Psychological Reports 1962 vol. 10, pp799-812 History The BPRS was initially developed by John E. Overall and Donald R. Gorham. It was created for the purpose of being able to quickly assess the patient’s psychiatric symptoms prior, during, or following a treatment. The items of the test were generated from conducting factor analysis on the Multidimensional Scale for Rating Psychiatric Patients and the Inpatient Multidimensional Psychiatric Scale. Sixteen factors were found from the analysis, which served as the building blocks for the BPRS. Later research in 1968 added two more factors to the BPRS, whi ...

Diagnostic Classification And Rating Scales Used In Psychiatry
Diagnosis is the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines, with variations in the use of logic, analytics, and experience, to determine " cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions.

Scale For The Assessment Of Negative Symptoms
The Scale for the Assessment of Negative Symptoms (SANS) is a rating scale that mental health professionals use to measure negative symptoms in schizophrenia. Negative symptoms are those conspicuous by their absence—lack of concern for one's appearance, and lack of language and communication skills, for example. Nancy Andreasen developed the scale and first published it in 1984. SANS splits assessment into five domains. Within each domain it rates separate symptoms from 0 (absent) to 5 (severe). The scale is closely linked to the Scale for the Assessment of Positive Symptoms (SAPS), which was published a few years later. These tools are available for clinicians and for research. Background Schizophrenia is a severe mental illness characterized by a range of behaviors, including hallucinations and delusions. Hallucinations refer to disorders involving the sensory systems, and are most often manifested as seeing or hearing things (e.g., voices) that do not exist. Delusions include ...
