In psychiatry, thought withdrawal is the delusional belief that thoughts have been 'taken out' of the patient's mind, and the patient has no power over this.It often accompanies thought blocking. The patient may experience a break in the flow of their thoughts, believing that the missing thoughts have been withdrawn from their mind by some outside agency. This delusion is one of Schneider's first rank symptoms for schizophrenia. Because thought withdrawal is characterized as a delusion, according to the DSM-IV TR it represents a positive symptom of schizophrenia.
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry.
Thought blocking, a phenomenon that occurs in people with psychiatric illnesses, occurs when a person's speech is suddenly interrupted by silences that may last a few seconds to a minute or longer. When the person begins speaking again, after the block, they will often speak about a subject unrelated to what was being discussed when blocking occurred. It is described as being experienced as an unanticipated, quick and total emptying of the mind. People with schizophrenia commonly experience thought blocking and may comprehend the experience in peculiar ways. For example a person with schizophrenia might remark that another person has removed their thoughts from their brain.
Schizophrenia is a mental disorder characterized by abnormal behavior, strange speech and a decreased ability to understand reality. Other symptoms include false beliefs, unclear or confused thinking, hearing voices that do not exist, reduced social engagement and emotional expression, and lack of motivation. People with schizophrenia often have additional mental health problems such as anxiety, depressive or substance-use disorders. Symptoms typically come on gradually, begin in young adulthood and in many cases never resolve.
The Diagnostic and Statistical Manual of Mental Disorders (DSM), published by the American Psychiatric Association (APA), offers a common language and standard criteria for the classification of mental disorders. It is used, or relied upon, by clinicians, researchers, psychiatric drug regulation agencies, health insurance companies, pharmaceutical companies, the legal system, and policy makers together with alternatives such as the ICD-10 Classification of Mental and Behavioural Disorders, produced by the WHO.
Psychosis is an abnormal condition of the mind that results in difficulties determining what is real and what is not. Symptoms may include false beliefs (delusions) and seeing or hearing things that others do not see or hear (hallucinations). Other symptoms may include incoherent speech and behavior that is inappropriate for the situation. There may also be sleep problems, social withdrawal, lack of motivation, and difficulties carrying out daily activities.
Paranoid schizophrenia is the most common type of schizophrenia. Schizophrenia is defined as “a chronic mental disorder in which a person loses touch with reality (psychosis)." Schizophrenia is divided into subtypes based on the “predominant symptomatology at the time of evaluation." The clinical picture is dominated by relatively stable and often persecutory delusions that are usually accompanied by hallucinations, particularly of the auditory variety, and perceptual disturbances. These symptoms can have a huge effect on functioning and can negatively affect quality of life. Paranoid schizophrenia is a lifelong disease, but with proper treatment, a person with the illness can attain a higher quality of life.
Hypochondriasis or hypochondria is a condition in which a person is excessively and unduly worried about having a serious illness. An old concept, its meaning has repeatedly changed due to redefinitions in its source metaphors. 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 or others have, or are about to be diagnosed with, a serious illness.
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—but does not meet the diagnostic criteria for schizophrenia or a mood disorder individually. The main criterion for the schizoaffective disorder diagnosis 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 important for providers to accurately diagnose patients, as treatment differs greatly for each of these diagnoses.
Kurt Schneider was a German psychiatrist known largely for his writing on the diagnosis and understanding of schizophrenia, as well as personality disorders then known as psychopathic personalities.
Panphobia, omniphobia, pantophobia, or panophobia is a vague and persistent dread of some unknown evil. Panphobia is not registered as a type of phobia in medical references.
Paranoid personality disorder (PPD) is a mental disorder characterized by paranoia and a pervasive, long-standing suspiciousness and generalized mistrust of others. People with this personality disorder may be hypersensitive, easily insulted, and habitually relate to the world by vigilant scanning of the environment for clues or suggestions that may validate their fears or biases. They are eager observers. They think they are in danger and look for signs and threats of that danger, potentially not appreciating other evidence.
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. The term prison psychosis is sometimes used because the syndrome occurs most frequently in prison inmates, where it may be seen as an attempt to gain leniency from prison or court officials. Psychological symptoms generally resemble the patient's sense of mental illness rather than any recognized category. The syndrome may occur in persons with other mental disorders such as schizophrenia, depressive disorders, toxic states, paresis, alcohol use disorders and factitious disorders. Ganser syndrome can sometimes be diagnosed as merely malingering, but it is more often defined as dissociative disorder.
The mental status examination or mental state examination (MSE) is an important part of the clinical assessment process in psychiatric practice. It is a structured way of observing and describing a patient's psychological functioning at a given point in time, under the domains of appearance, attitude, behavior, mood, and affect, speech, thought process, thought content, perception, cognition, insight, and judgment. There are some minor variations in the subdivision of the MSE and the sequence and names of MSE domains.
Schizophreniform disorder is a mental disorder diagnosed when symptoms of schizophrenia are present for a significant portion of the time within a one-month period, but signs of disruption are not present for the full six months required for the diagnosis of schizophrenia.
Paraphrenia is a mental disorder characterized by an organized system of paranoid delusions with or without hallucinations and without deterioration of intellect or personality.
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 significant practical importance.
Grandiose delusions (GD), delusions of grandeur, expansive delusions are a subtype of delusion that occur in patients suffering from a wide range of psychiatric diseases, including two-thirds of patients in manic state of bipolar disorder, half of those with schizophrenia, patients with the grandiose subtype of delusional disorder, and a substantial portion of those with substance abuse disorders. GDs are characterized by fantastical beliefs that one is famous, omnipotent, wealthy, or otherwise very powerful. The delusions are generally fantastic and typically have a religious, science fictional, or supernatural theme. There is a relative lack of research into GD, in contrast to persecutory delusions and auditory hallucinations. About 10% of healthy people experience grandiose thoughts but do not meet full criteria for a diagnosis of GD.
Personality disorder not otherwise specified is a DSM-IV Axis II personality disorder.
Persecutory delusions are a set of delusional conditions in which the affected persons believe they are being persecuted. Specifically, they have been defined as containing two central elements:
Childhood schizophrenia is a schizophrenia spectrum disorder that is characterized by hallucinations, disorganized speech, delusions, catatonic behavior and "negative symptoms", such as inappropriate or blunted affect and avolition with onset before 13 years of age. The term "childhood-onset schizophrenia" and "very early-onset schizophrenia" are used to identify patients in whom the disorder manifests before the age of 13.
The diagnosis of schizophrenia is based on criteria in either the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, version DSM-5, or the World Health Organization's International Statistical Classification of Diseases and Related Health Problems, the ICD-10. Clinical assessment is performed by a mental health professional based on observed behavior, reported experiences, and reports of others familiar with the person. Symptoms associated with schizophrenia occur along a continuum in the population and must reach a certain severity and level of impairment before a diagnosis is made.
Simple-type schizophrenia is a sub-type of schizophrenia as defined in the International Classification of Diseases (ICD-10). It is not included in the current Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Simple-type schizophrenia is characterized by negative ("deficit") symptoms, such as avolition, apathy, anhedonia, reduced affect display, lack of initiative, lack of motivation, low activity; with absence of hallucinations or delusions of any kind.
