  • Kanji (Morphogram) and Kana (Phonogram) Problem in Japanese Alexia and Agraphia. [Journal Article]
    Front Neurol Neurosci 2019; 44:53-63Sakurai Y
  • The kanji and kana (or kanji vs. kana) problem in the Japanese language denotes the dissociation between kanji (morphograms) and kana (phonograms) in reading/comprehension and writing. Since paragraphia of kana in a patient with amyotrophic lateral sclerosis was first reported in 1893, kanji-kana dissociation has been the central topic in Japanese aphasiology. Recent advancements in lesion-to-sym…
  • Alexia and Agraphia from 1861 to 1965. [Journal Article]
    Front Neurol Neurosci 2019; 44:39-52Henderson VW
  • Studies of alexia and agraphia have played historically important roles in efforts to understand the relation between brain and behavior. In the second half of the 19th century, works by Paul Broca and Carl Wernicke led to the concept of delimited cortical centers in the left cerebral hemisphere concerned with discrete aspects of spoken and written language. These specialized centers were linked …
  • Alexia and Agraphia Intervention Following Traumatic Brain Injury: A Single Case Study. [Journal Article]
    Am J Speech Lang Pathol 2019; 28(3):1152-1166Hux K, Mahrt T
  • Purpose This case study documents the effectiveness of a multicomponent intervention for an adolescent with acquired alexia and agraphia following severe traumatic brain injury. Method Initial testing revealed severe central alexia and surface agraphia with concomitant anomic aphasia. Intervention components included sight word drills, modified Multiple Oral Reading (MOR) procedures, functional r…
  • Cognitive Rehabilitation of Acquired Calculation Disturbances. [Review]
    Behav Neurol 2019; 2019:3151092Ardila A, Rosselli M
  • Acalculia is an acquired disorder in calculation abilities, usually associated with left posterior parietal damage. Two types of acalculic disorders are usually distinguished: (1) primary acalculia or anarithmetia, where the patient presents a loss of numerical concepts (difficulties are observed both in oral and written calculations), and (2) secondary acalculia due to a different disturbance in…
  • The making of a syndrome: The English translation of Gerstmann's first report. [Journal Article]
    Cortex 2019; 117:277-283Rusconi E, Cubelli R
  • The label Gerstmann syndrome indicates the co-occurrence of four symptoms in persons with acquired brain lesions: finger agnosia, left-right disorientation, agraphia, and acalculia. The syndrome is often associated with a lesion affecting the posterior parietal lobe of the left cerebral hemisphere. Virtually every paper discussing this tetrad of symptoms refers back to Josef Gerstmann's (1924) fi…
  • Seeing is not believing. [Journal Article]
    Surv Ophthalmol 2019Foster Z, Kini A, … Vaphiades M
  • An 84-year-old woman with a history of dry age-related macular degeneration presented with an acute inability to read, but intact writing ability (pure alexia or alexia without agraphia). She denied any difficulty speaking, paresthesias, or hemiparesis. Her visual acuity was 20/20 in each eye. Macular examination, optical coherence tomography, and fluorescein angiography demonstrated the previous…
  • Maurice Ravel's dementia: the silence of a genius. [Journal Article]
    Arq Neuropsiquiatr 2019; 77(2):136-138Vitturi BK, Sanvito WL
  • Maurice Ravel is one of the most important French musicians. In the last years of his life, Ravel was victim of a dementia of uncertain etiology that caused aphasia, apraxia, agraphia and amusia. The artistic brain of the author of eternal musical compositions was progressively silenced due to his neurodegenerative disease. On the 90th anniversary of Boléro, this historical note revisits Ravel's …
  • Gray Matter Correlates of Finger Gnosis in Children: A VBM Study. [Journal Article]
    Neuroscience 2019; 404:82-90Soylu F, Seo R, … Newman SD
  • Accumulating evidence relates finger gnosis (also called finger sense or finger gnosia), the ability to identify and individuate fingers, to cognitive processing, particularly numerical cognition. Multiple studies have shown that finger gnosis scores correlate with or predict numerical skills in children. Neuropsychological cases as well as magnetic stimulation studies have also shown that finger…
  • Phenotypic variability and neuropsychological findings associated with C9orf72 repeat expansions in a Bulgarian dementia cohort. [Journal Article]
    PLoS One 2018; 13(12):e0208383Mehrabian S, Thonberg H, … Graff C
  • CONCLUSIONS: This study represents the first genetic screening for C9orf72 repeat expansions in a Bulgarian dementia cohort. The C9orf72 repeat expansion does not appear to be a common cause of FTD and related disorders. This report confirms the notion that C9orf72 repeat expansions underlie a broad spectrum of neurodegenerative phenotypes. Relatively isolated agraphia in two cases with C9orf72 repeat expansions is a strong motivation to provide detailed and sophisticated oral and written language assessments that can be used to more precisely characterize early cognitive deficits in these heterogeneous conditions.
