  • Rolandic Epilepsy

    Abstract Summary: Purpose: We wished to determine incidence, clinical features, and prognosis of benign rolandic seizures (BRS) and benign rolandic epilepsy (BRE) in a total population. Methods: Cases were ascertained through review of all EEG records, and diagnosis was verified by review of medical records.[…][doi.org]

  • Creutzfeldt Jakob Disease

    Although MM2‐cortical‐type sCJD generally shows slow progression without myoclonus or periodic sharpwave complexes, the present patient showed a rapidly progressive clinical[www3.interscience.wiley.com] Periodic sharp wave complexes every 1 to 2 seconds over slowed background were found on EEG, and MRI showed cerebellar and bifrontal cortical T2/FLAIR/DWI hypersignal without[ncbi.nlm.nih.gov] A 76-year-old man was transferred to a tertiary neurology center with a clinical history of 6-month weight loss, cognitive disturbance, and nonspecific generalized weakness[ncbi.nlm.nih.gov]

  • Fragile X Syndrome

    Fragile-X syndrome (FXS) is a frequent genetic form of intellectual disability (ID). The main recurrent mutagenic mechanism causing FXS is the expansion of a CGG repeat sequence in the 5'-UTR of the FMR1 gene, therefore, routinely tested in ID patients. We report here three FMR1 intragenic pathogenic variants not[…][ncbi.nlm.nih.gov]

  • Vascular Dementia

    Many of the previous studies of vascular dementia using proton magnetic resonance (MR) spectroscopy had been carried out on white matter. However, no proton spectroscopic data of the subcortical gray matter are available in such disease. We report two cases suffering from vascular dementia, with an unilateral[…][ncbi.nlm.nih.gov]

  • Periventricular Leukomalacia

    Hemorrhage into areas of periventricular leukomalacia may occur and range in size from microscopic to massive. Hitherto, the definitive diagnosis has been made only at autopsy. A case is described in which the diagnosis of hemorrhagic periventricular leukomalacia was made antemortem by real-time ultrasound scanning[…][ncbi.nlm.nih.gov]
