The concept of “hysteria” comes from the Greek word “hystera” (uterus) and dates back to the time of Hippocrates, at least. Modern classifications differ regarding the area encompassed by the concepts of dissociation and conversion differ. Mental health professionals in the United States (DSM-5) use a standard classification of mental disorders codifying dissociative disorders as a distinct class of disorders, but subsumes conversion disorders under “somatoform disorders”. The history of hysteria is as long as the history of mankind. Apparently, both the essence and mechanisms of dissociative disorders remain unchanged despite the fact that many years have passed. According to Owczarek et al., dissociative symptoms are caused by the malfunctioning of defence mechanisms and anxiety. This article provides an overview of the available literature on the etiology and pathogenesis of dissociative disorders as well as disorders such as amnesia, dissociative fugue, trance and possession.
Rett syndrome is a neurodevelopmental genetic disorder and, because of some behavioral characteristics, individuals affected by the disease are known as silent angels. Girls with Rett syndrome perform stereotyped movements, they have learning difficulties, their reaction time is prolonged, and they seem alienated in the environment. These children require constant pediatric, neurological and orthopedic care. In the treatment of Rett syndrome physical therapy, music therapy, hydrotherapy, hippotherapy, behavioral methods, speech therapy and diet, are also used. In turn, psychological therapy of the syndrome is based on the sensory integration method, using two or more senses simultaneously. In 80% of cases, the syndrome is related to mutations of the MECP2 gene, located on chromosome X. The pathogenesis of Rett syndrome is caused by the occurrence of a non-functional MeCP2 protein, which is a transcription factor of many genes, i.e. Bdnf, mef2c, Sgk1, Uqcrc1. Abnormal expression of these genes reveals a characteristic disease phenotype. Clinical symptoms relate mainly to the nervous, respiratory, skeletal and gastrointestinal systems. Currently causal treatment is not possible. However, researchers are developing methods by which, perhaps in the near future, it will be possible to eliminate the mutations in the MECP2 gene, and this will give a chance to the patient for normal functioning.The paper presents the etiology and pathogenesis of the disease, genetic, clinical, pharmacological aspects and other forms of Rett syndrome treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
