          Abstract

          Simultanagnosia resulting from dorsal stream dysfunction is an under recognized condition. In this case report we describe the case of a young woman who developed posterior reversible encephalopathy syndrome (PRES), and who recovered visual acuities of 20/20 in each eye, along with normal visual fields and contrast sensitivities, yet experienced persistent symptoms of perceptual dysfunction. Detailed and systematic history taking revealed consistent visual difficulties typical of dorsal stream dysfunction. After a detailed explanation of her symptomatology and training in a range of strategies to cope, the patient experienced a great improvement in her day-to-day functioning.

            Posterior reversible encephalopathy syndrome in eclampsia.

            Ravindra Garg, Neeraj Kumar, Hardeep Malhotra (2018)
            Posterior reversible encephalopathy syndrome is characterized by acute headache, visual impairment, seizures, and altered mental status; neuroimaging may show cerebral edema affecting the parietal and occipital lobes of the brain. The objective of this article is to review the current understanding of posterior reversible encephalopathy syndrome in eclampsia. Literature was searched from PubMed, Scopus, and Google Scholar databases. The search terms included "eclampsia", "eclampsia and posterior reversible encephalopathy syndrome", and "pregnancy and posterior reversible encephalopathy syndrome". We reviewed all published original articles with the search term "posterior reversible encephalopathy syndrome". Up to 100% of eclamptic patients may have reversible posterior leukoencephalopathy syndrome. Two putative mechanisms - "vasogenic" and "vasospasm" - are considered to be responsible. Cerebral edema and petechial cortical hemorrhages are common autopsy findings. Clinical and neuroimaging manifestations are reversible in the majority of patients. Prompt correction of increased blood pressure and treatment of seizures are the cornerstones of treatment. Magnesium sulfate is the drug of choice for seizures. Some survivors may have permanent vision loss and other disabling sequelae. In conclusion, posterior reversible encephalopathy is a devastating complication of eclampsia. Early recognition helps in preventing some of its devastating sequelae.
