Schizophrenia is a mental disorder characterized by abnormalsocial behavior and failure to understand what is real. The last may range from loss of train of thought, to sentences only loosely connected in meaning, to speech that is not understandable known as word salad. Social withdrawal, sloppiness of dress and hygiene, and loss of motivation and judgment are all common in schizophrenia. Social isolation commonly occurs. They can include delusions, disordered thoughts and speech, and tactile, auditory, visual, olfactory and gustatory hallucinations, typically regarded as manifestations of psychosis. Negative symptoms appear to contribute more to poor quality of life, functional ability, and the burden on others than do positive symptoms. Welcome to the Amnesia: The Dark Descent website.

Find out about the causes, symptoms and treatment options for amnesia.Verbal memory impairment has been linked to a decreased ability in individuals with schizophrenia to semantically encode (process information relating to meaning), which is cited as a cause for another known deficit in long- term memory. One idea is that genes are involved in the evolution of language and human nature, but to date such ideas remain little more than hypothetical in nature. Cognitive biases have been identified in those with the diagnosis or those at risk, especially when under stress or in confusing situations.

Schizophrenia is one of many mental disorders that includes loss of personality, confusion, psychosis, catatonia, agitation, delusions, and hallucinations. It is uncertain whether these volumetric changes are progressive or exist prior to the onset of the disease. This focus largely resulted from the accidental finding that phenothiazine drugs, which block dopamine function, could reduce psychotic symptoms. It is also supported by the fact that amphetamines, which trigger the release of dopamine, may exacerbate the psychotic symptoms in schizophrenia. Although postulated for about 2. D2 blockade effect common to all antipsychotics, it was not until the mid- 1. PET and SPET imaging studies provided supporting evidence. The dopamine hypothesis is now thought to be simplistic, partly because newer antipsychotic medication (atypical antipsychotic medication) can be just as effective as older medication (typical antipsychotic medication), but also affects serotonin function and may have slightly less of a dopamine blocking effect. These criteria use the self- reported experiences of the person and reported abnormalities in behavior, followed by a clinical assessment by a mental health professional. Symptoms associated with schizophrenia occur along a continuum in the population and must reach a certain severity before a diagnosis is made. To be diagnosed with schizophrenia, two diagnostic criteria have to be met over much of the time of a period of at least one month, with a significant impact on social or occupational functioning for at least six months. The person had to be suffering from delusions, hallucinations, or disorganized speech. A second symptom could be negative symptoms, or severely disorganized or catatonic behaviour. These were retained in previous revisions largely for reasons of tradition, but had subsequently proved to be of little worth. The ICD- 1. 0 criteria put more emphasis on Schneiderian first- rank symptoms. In practice, agreement between the two systems is high. Psychotic symptoms lasting less than a month may be diagnosed as brief psychotic disorder, and various conditions may be classed as psychotic disorder not otherwise specified, while schizoaffective disorder is diagnosed if symptoms of mood disorder are substantially present alongside psychotic symptoms. If the psychotic symptoms are the direct physiological result of a general medical condition or a substance, then the diagnosis is one of a psychosis secondary to that condition. Delusions are persecutory and/or grandiose, but in addition to these, other themes such as jealousy, religiosity, or somatization may also be present. Where thought disorder and flat affect are present together. Symptoms can include catatonic stupor and waxy flexibility. Schizotypal personality disorder has symptoms that are similar but less severe than those of schizophrenia. It can resemble schizophrenia and be misdiagnosed as such. Stroke, multiple sclerosis, hyperthyroidism, hypothyroidism and dementias such as Alzheimer's disease, Huntington's disease, frontotemporal dementia and Lewy Body dementia may also be associated with schizophrenia- like psychotic symptoms. Investigations are not generally repeated for relapse unless there is a specific medical indication or possible adverse effects from antipsychotic medication. In children hallucinations must be separated from typical childhood fantasies. Long- term hospitalization is uncommon since deinstitutionalization beginning in the 1. Some evidence indicates that regular exercise has a positive effect on the physical and mental health of those with schizophrenia. Antipsychotics, however, fail to significantly improve the negative symptoms and cognitive dysfunction. People on typical antipsychotics tend to have a higher rate of extrapyramidal side effects while some atypicals are associated with considerable weight gain, diabetes and risk of metabolic syndrome; this is most pronounced with olanzapine, while risperidone and quetiapine are also associated with weight gain. This has been cited at 1. These are called first- rank symptoms or Schneider's first- rank symptoms. They include delusions of being controlled by an external force, the belief that thoughts are being inserted into or withdrawn from one's conscious mind, the belief that one's thoughts are being broadcast to other people, and hearing hallucinatory voices that comment on one's thoughts or actions or that have a conversation with other hallucinated voices. A review of the diagnostic studies conducted between 1. Schneider's claims, and suggested that first- rank symptoms should be de- emphasized in future revisions of diagnostic systems. A detailed case report in 1. James Tilly Matthews, and accounts by Philippe Pinel published in 1. In 1. 89. 3 Emil Kraepelin borrowed the term from Schule and Pick and in 1. However, this account ignores the fact that there is little to connect Morel's descriptive use of the term and the independent development of the dementia praecox disease concept at the end of the nineteenth century. American and British interpretations of Bleuler led to the claim that he described its main symptoms as four A's: flattened affect, autism, impaired association of ideas, and ambivalence. Treatment was revolutionized in the mid- 1. It became clear after the 1. US. David Rosenhan's 1. Science under the title . Although some people diagnosed with schizophrenia may hear voices and may experience the voices as distinct personalities, schizophrenia does not involve a person changing among distinct, multiple personalities; the confusion arises in part due to the literal interpretation of Bleuler's term .

Environmental factors later in life (during early childhood. In fact experts now say that schizophrenia (and all other mental illness) is caused by a combination of biological, psychological and social factors, and this understanding of mental illness is called the bio- psycho- social model. The Path to Schizophrenia - The diagram above shows how biological, genetic and prenatal factors are believed to create a vulnerability to schizophrenia. Additional envronmental exposures (for example, frequent or ongoing social stress and/or isolation during childhood, drug abuse, etc.) then further increase the risk or trigger the onset of psychosis and schizophrenia. Early signs of schizophrenia risk include neurocognitive impairments, social anxiety (shyness) and isolation and . Source: Presentation by Dr. Moreover. risk factors may be different for different individuals - while one. The exact process by which environmental factors and stress gets translated into brain changes and ultimately psychosis or schizophrenia is increasingly thought to be a result of epigenetics, and recent research suggests exactly how stress might trigger these brain changes. Research has now shown that children's and teen's brains are very sensitive to stress (up to 5 to 1. What seems like mild to moderate stress for an adult, may be very severe stress for a child. This stress- related brain damage can greatly increase risk for many types of mental illness later in life.
