This condition can manifest itself with various neurological symptoms, including epileptic seizures, cognitive impairment, and movement disorders. PFBC is most often hereditary and can manifest itself in childhood or adolescence, but cases of manifestation in adults have also been reported. Given the neurological nature of the disease, its diagnosis and treatment require a comprehensive approach, including both clinical and laboratory studies.<\/p>\n<div id=\"ez-toc-container\"

of the disease and interesting historical facts<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Primary familial calcification of the brain was first described in the scientific literature in the early 20th century. One of the first cases was a report of a family in which several members had abnormal calcium deposits in the brain structures. Since then, researchers have begun to identify inheritance patterns and links between genetic mutations and clinical manifestations of the disease. In the 1970s, cases of calcification in children attracted the attention of scientists, which served as a stimulus for more in-depth study of the disease. In the 1980s, research led to the identification of several genes associated with the disease, opening up a new direction in diagnosis and therapy. PFCM remains an active area of research, and scientists continue to study its pathogenesis and potential treatments.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%AD%D0%BF%D0%B8%D0%B4%D0%B5%D0%BC%D0%B8%D0%BE%D0%BB%D0%BE%D0%B3%D0%B8%D1%8F\"><\/span>Epidemiology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Prevalence statistics for PFCM are limited due to the rarity of the disorder. Estimates suggest that its incidence ranges from 1 in 100,000 to 1 in 200,000 individuals in different populations. The disorder appears to have a higher incidence in certain families, suggesting that it may be hereditary. It is also worth noting that cases of PFCM may go unreported due to a lack of awareness among physicians about the disorder, leading to underreporting and statistical distortion. In addition to the still unrecognized cases, certain ethnic groups are less likely to develop the disorder.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%93%D0%B5%D0%BD%D0%B5%D1%82%D0%B8%D1%87%D0%B5%D1%81%D0%BA%D0%B0%D1%8F_%D0%BF%D1%80%D0%B5%D0%B4%D1%80%D0%B0%D1%81%D0%BF%D0%BE%D0%BB%D0%BE%D0%B6%D0%B5%D0%BD%D0%BD%D0%BE%D1%81%D1%82%D1%8C_%D0%BA_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%BC%D1%83_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8E\"><\/span>Genetic predisposition to this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Primary familial calcification of the brain is caused by mutations in various genes, the most significant of which are SLC20A2 and PDGFRB. These genes are involved in the regulation of calcification processes and cell metabolism, which leads to a disruption of these functions in the case of abnormal changes. Transmission of the disease is carried out according to the dominant type of inheritance, which indicates the possibility of transmission of the mutation from one parent to a child even in the case of an unmanifested disease in the parent. In some cases, mutations were also found in the genes responsible for the transport and deposition of calcium, which confirms the multifactorial nature of the pathogenesis.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"%D0%A4%D0%B0%D0%BA%D1%82%D0%BE%D1%80%D1%8B_%D1%80%D0%B8%D1%81%D0%BA%D0%B0_%D0%B2%D0%BE%D0%B7%D0%BD%D0%B8%D0%BA%D0%BD%D0%BE%D0%B2%D0%B5%D0%BD%D0%B8%D1%8F_%D0%B4%D0%B0%D0%BD%D0%BD%D0%BE%D0%B3%D0%BE_%D0%B7%D0%B0%D0%B1%D0%BE%D0%BB%D0%B5%D0%B2%D0%B0%D0%BD%D0%B8%D1%8F\"><\/span>Risk factors for the development of this disease<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Although genetic predisposition is the main risk factor, there are other aspects that may contribute to the development of PFCM.
