  • 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]

  • Rolandic Epilepsy

    Benign Rolandic epilepsy or benign childhood epilepsy with centrotemporal spikes (BCECTS) is the most common epilepsy syndrome in childhood. Most children will outgrow the syndrome (it starts around the age of 3–13 with a peak around 8–9 years and stops around age 14–18), hence the label benign. The seizures,[…][en.wikipedia.org]

  • Creutzfeldt Jakob Disease

    Classic CJD is a human prion disease. It is a neurodegenerative disorder with characteristic clinical and diagnostic features. This disease is rapidly progressive and always fatal. Infection with this disease leads to death usually within 1 year of onset of illness. Important Note: Classic CJD is not related to "mad cow"[…][web.archive.org]

  • Periventricular Leukomalacia

  • 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]

  • Benign Adult Familial Myoclonic Epilepsy

    The classic interictal EEG finding is the hypsarrhythmia pattern, which consists of a highvoltage, disorganized background with multifocal spike and sharp waves.[euroformhealthcare.biz] Alvarez and Lombroso reported hypnagogic paroxysmal spike wave activity (minimal epileptiform features, sharp waves embedded into hyperventilation, or hypnagogic hypersynchrony[euroformhealthcare.biz] This pattern may first occur during non-rapid eye movement sleep and may disappear during rapid eye movement (active sleep) sleep or the waking state.[euroformhealthcare.biz]
