Intermetamorphosis
Intermetamorphosis is a delusional misidentification syndrome, related to agnosia. The main symptoms consist of patients believing that they can see others change into someone else in both external appearance and internal personality. The disorder is usually comorbid with neurological disorders or mental disorders. The disorder was first described in 1932 by Paul Courbon (1879–1958), a French psychiatrist.''Illusions d'intermétamorphose et de la charme'', Annales Medico-Psychologiques, issue 14, page 401-406. Intermetamorphosis is rare, although issues with diagnostics and comorbidity may lead to under-reporting.Cipriani, G., Vedovello, M., Ulivi, M., Lucetti, C., Fiorino, A. D., & Nuti, A. (2013). Delusional Misidentification Syndromes and Dementia: A Border Zone Between Neurology and Psychiatry. American Journal of Alzheimer’s Disease & Other Dementias, 28(7), 671–678.

Delusional Misidentification Syndrome
Delusional misidentification syndrome is an umbrella term, introduced by Christodoulou (in his book ''The Delusional Misidentification Syndromes'', Karger, Basel, 1986) for a group of delusional disorders that occur in the context of mental and neurological illness. They all involve a belief that the identity of a person, object, or place has somehow changed or has been altered. As these delusions typically only concern one particular topic, they also fall under the category called monothematic delusions. This psychopathological syndrome is usually considered to include four main variants: * The Capgras delusion is the belief that (usually) a close relative or spouse has been replaced by an identical-looking impostor. * The Fregoli delusion is the belief that various people the believer meets are actually the same person in disguise. * Intermetamorphosis is the belief that an individual has the ability to take the form of another person in both external appearance and interna ...

Perirhinal Cortex
The perirhinal cortex is a cortical region in the medial temporal lobe that is made up of Brodmann areas 35 and 36. It receives highly processed sensory information from all sensory regions, and is generally accepted to be an important region for memory. It is bordered caudally by postrhinal cortex or parahippocampal cortex (homologous regions in rodents and primates, respectively) and ventrally and medially by entorhinal cortex. Structure The perirhinal cortex is composed of two regions: areas 36 and 35. Area 36 is sometimes divided into three subdivisions: 36d is the most rostral and dorsal, 36r ventral and caudal, and 36c the most caudal. Area 35 can be divided in the same manner, into 35d and 35v (for dorsal and ventral, respectively). Area 36 is six-layered, dysgranular, meaning that its layer IV is relatively sparse. Area 35 is agranular cortex (lacking any cells in layer IV). Function The perirhinal cortex is involved in both visual perception and memory; it ...

Carbamazepine
Carbamazepine (CBZ), sold under the trade name Tegretol among others, is an anticonvulsant medication used primarily in the treatment of epilepsy and neuropathic pain. It is used as an adjunctive treatment in schizophrenia along with other medications and as a second-line agent in bipolar disorder. Carbamazepine appears to work as well as phenytoin and valproate for focal and generalized seizures. It is not effective for absence seizure, absence or myoclonic seizures. Carbamazepine was discovered in 1953 by Swiss chemist Walter Schindler. It was first marketed in 1962. It is available as a generic medication. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essential Medicines. In 2020, it was the 185th most commonly prescribed medication in the United States, with more than 2million prescriptions. Medical uses Carbamazepine is typically used for the treatment of seizure disorders and neuropathic pain. It is used off-label use, off-lab ...

Haloperidol
Haloperidol, sold under the brand name Haldol among others, is a typical antipsychotic medication. Haloperidol is used in the treatment of schizophrenia, tics in Tourette syndrome, mania in bipolar disorder, delirium, agitation, acute psychosis, and hallucinations from alcohol withdrawal. It may be used by mouth or injection into a muscle or a vein. Haloperidol typically works within 30 to 60 minutes. A long-acting formulation may be used as an injection every four weeks by people with schizophrenia or related illnesses, who either forget or refuse to take the medication by mouth. Haloperidol may result in a movement disorder known as tardive dyskinesia which may be permanent. Neuroleptic malignant syndrome and QT interval prolongation may occur. In older people with psychosis due to dementia it results in an increased risk of death. When taken during pregnancy it may result in problems in the infant. It should not be used by people with Parkinson's disease. Haloperidol w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pimozide
Pimozide (sold under the brand name Orap) is an antipsychotic drug of the diphenylbutylpiperidine class. It was discovered at Janssen Pharmaceutica in 1963. It has a high potency compared to chlorpromazine (ratio 50-70:1). On a weight basis it is even more potent than haloperidol. It also has special neurologic indications for Tourette syndrome and resistant tics. The side effects include akathisia, tardive dyskinesia, and, more rarely, neuroleptic malignant syndrome and prolongation of the QT interval. Medical uses Pimozide is used in its oral preparation in schizophrenia and chronic psychosis (on-label indications in Europe only), Tourette syndrome, and resistant tics (Europe, United States and Canada). There have been numerous studies showing Pimozide can be used successfully to treat Delusional parasitosis and traditionally was the drug of choice. However, newer medications have become prevalent recently as the preferred medication. In one case a series of 33 patie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trifluoperazine
Trifluoperazine, marketed under the brand name Stelazine among others, is a typical antipsychotic primarily used to treat schizophrenia. It may also be used short term in those with generalized anxiety disorder but is less preferred to benzodiazepines. It is of the phenothiazine chemical class. Medical uses Schizophrenia Trifluoperazine is an effective antipsychotic for people with schizophrenia. There is low-quality evidence that trifluoperazine increases the chance of being improved when compared to placebo when people are followed up for 19 weeks. There is low-quality evidence that trifluoperazine reduces the risk of relapse when compared with placebo when people are followed for 5 months. As of 2014 there was no good evidence for a difference between trifluoperazine and placebo with respect to the risk of experiencing intensified symptoms over a 16-week period nor in reducing significant agitation or distress. There is no good evidence that trifluoperazine is more effecti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulpiride
Sulpiride, sold under the brand name Dogmatil among others, is an atypical antipsychotic (although some texts have referred to it as a typical antipsychotic) medication of the benzamide class which is used mainly in the treatment of psychosis associated with schizophrenia and major depressive disorder, and sometimes used in low dosage to treat anxiety and mild depression. Sulpiride is commonly used in Asia, Central America, Europe, South Africa and South America. Levosulpiride is its purified levo-isomer and is sold in India for similar purpose. It is not approved in the United States, Canada, or Australia. The drug is chemically and clinically similar to amisulpride. Medical uses Sulpiride's primary use in medicine is in the management of the symptoms of schizophrenia. It has been used as both a monotherapy and adjunctive therapy (in case of treatment-resistance) in schizophrenia. It has also been used in the treatment of dysthymia. There is evidence, although low quality, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quetiapine
Quetiapine, sold under the brand name Seroquel among others, is an atypical antipsychotic medication used for the treatment of schizophrenia, bipolar disorder, and major depressive disorder. Despite being widely used as a sleep aid due to its sedating effect, the benefits of such use do not appear to generally outweigh the side effects. It is taken orally. Common side effects include sleepiness, constipation, weight gain, and dry mouth. Other side effects include low blood pressure with standing, seizures, a prolonged erection, high blood sugar, tardive dyskinesia, and neuroleptic malignant syndrome. In older people with dementia, its use increases the risk of death. Use in the third trimester of pregnancy may result in a movement disorder in the baby for some time after birth. Quetiapine is believed to work by blocking a number of receptors including serotonin and dopamine. Quetiapine was developed in 1985 and approved for medical use in the United States in 1997. ...

Risperidone
Risperidone, sold under the brand name Risperdal among others, is an atypical antipsychotic used to treat schizophrenia and bipolar disorder. It is taken either by mouth or by injection (subcutaneous or intramuscular). The injectable versions are long-acting and last for 2–4 weeks. Common side effects include movement problems, sleepiness, dizziness, trouble seeing, constipation, and increased weight. Serious side effects may include the potentially permanent movement disorder tardive dyskinesia, as well as neuroleptic malignant syndrome, an increased risk of suicide, and high blood sugar levels. In older people with psychosis as a result of dementia, it may increase the risk of death. It is unknown if it is safe for use in pregnancy. Its mechanism of action is not entirely clear, but is believed to be related to its action as a dopamine and serotonin antagonist. Study of risperidone began in the late 1980s and it was approved for sale in the United States in 1993. It is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olanzapine
Olanzapine (sold under the trade name Zyprexa among others) is an atypical antipsychotic primarily used to treat schizophrenia and bipolar disorder. For schizophrenia, it can be used for both new-onset disease and long-term maintenance. It is taken by mouth or by injection into a muscle. Common side effects include weight gain, movement disorders, dizziness, feeling tired, constipation, and dry mouth. Other side effects include low blood pressure with standing, allergic reactions, neuroleptic malignant syndrome, high blood sugar, seizures, and tardive dyskinesia. In older people with dementia, its use increases the risk of death. Use in the later part of pregnancy may result in a movement disorder in the baby for some time after birth. Although how it works is not entirely clear, it blocks dopamine and serotonin receptors. Olanzapine was patented in 1991 and approved for medical use in the United States in 1996. It is available as a generic medication. In 2020, it was the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clozapine
Clozapine is a psychiatric medication and is the first atypical antipsychotic (also called second-generation antipsychotic). It is primarily used to treat people with schizophrenia and schizoaffective disorders who have had an inadequate response to other antipsychotics or who have been unable to tolerate other drugs due to extrapyramidal side effects. It is also used for the treatment of psychosis in Parkinson's disease. Clozapine is regarded as the gold-standard treatment when other medication has been insufficiently effective and its use is recommended by multiple international treatment guidelines, after resistance to earlier neuroleptic treatment is established. The role of clozapine in treatment-resistant schizophrenia was established by a 1988 landmark study in which clozapine showed marked benefits compared to chlorpromazine in a group of patients with protracted psychosis who had already shown an inadequate response to other antipsychotics. While there are signific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antipsychotics
Antipsychotics, also known as neuroleptics, are a class of 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 involuntary movement disorders, gynecomastia, impotence, weight gain and metabolic syndrome. Long-term use can produce adverse effects su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
