  • Dissociative Trance Led to a Catastrophe: A Case Report
    by Ahmed Z Salama on January 27, 2025

    Dissociation is a cognitive process that disrupts consciousness, identity, or memory. It is frequently used as a form of defense in response to significant stress or trauma. In serious situations, it might show as a dissociative disorder, which extremely impairs psychological functioning. Dissociative trance, a type of other specified dissociative disorder (OSDD), is characterized by an abrupt loss of awareness, leading to unresponsiveness and involuntary actions. Despite being conscious, the...

  • Cardiac calcified amorphous tumor as a potential cause of cerebral infarction: A clinical case report
    by Hyunjin Kim on January 27, 2025

    We report the case of a 62-year-old male on long-term hemodialysis who was admitted to our hospital due to acute cerebral infarction associated with a cardiac calcified amorphous tumor (CAT). The patient presented with recurrent episodes of syncope and retrograde amnesia. Brain MRI identified multiple acute cerebral infarctions, while transthoracic echocardiography (TTE) revealed a 2.5 cm echogenic mobile mass attached to the ventricular side of the posterior mitral leaflet. The patient...

  • Functional independence trajectories over 5 years in older veterans with traumatic brain injury: A model systems study
    by Mia E Dini on January 27, 2025

    CONCLUSIONS: Similar to previously published studies in civilian populations, older veterans with TBI may be at risk for functional and cognitive decline. This study's findings increase the field's understanding of functional trajectories after TBI in older adults and may help identifty those who are at risk for lower functional outcomes.

  • An "Engram-Centric" Approach to Transient Global Amnesia (TGA) and Other Acute-Onset Amnesias
    by Andrew J Larner on January 24, 2025

    The differential diagnosis of acute-onset amnesia includes transient global amnesia (TGA), transient epileptic amnesia (TEA), and functional (or psychogenic) amnesia. The most common of these, TGA, is a rare but well-described condition characterised by a self-limited episode of dense anterograde amnesia with variable retrograde amnesia. Although the clinical phenomenology of TGA is well described, its pathogenesis is not currently understood, thus preventing the development of evidence-based...
