Reduplicative paramnesia in Morvan's syndrome

Morvan syndrome: Clinical and serological observations in 29 cases

“…Additional features that distinguished these patients from classical LE were the presence of a neuropathic lower limb pain, weight loss, male gender, and thymoma (±MG), although thymomas can also be found in rare cases diagnosed with LE 24. Six patients who each lacked 1 of the core features of NMT, autonomic disturbance, and insomnia (Supplementary Table 4), and others previously reported,1, 25–27 suggest the existence of conditions with only 2 of these 3 core components.…”

Toward a neurobiology of delusions

“…Delusions are the extraordinary and tenacious false beliefs suffered by patients with various ailments ranging from schizophrenia (Schneider, 1959), to traumatic brain injury (Coltheart et al , 2007), Alzheimer’s (Flint, 1991) and Parkinson’s disease (Ravina et al , 2007), the ingestion of psychotogenic drugs (Corlett et al , 2009a) and, less frequently, autoimmune disorders such as Morvan’s syndrome (Hudson et al , 2008) or potassium channel encephalopathy (Parthasarathi et al , 2006). Given this range of potential diagnoses, each with its own candidate neuropathology, it is perhaps unsurprising that we have not converged upon an agreed neurobiology of delusions.…”

Modulation of environmental reduplicative paramnesia by perceptual experience

“…Any substantial or systematic reproduction, redistribution, reselling, loan, sub-licensing, systematic supply, or distribution in any form to anyone is expressly forbidden.

ERP is often accompanied by other cognitive deficits affecting memory, executive, attentional, visuospatial, and topographical functions (Benson et al, 1976;Benson & Stuss, 1990;Budson et al, 2000;Hakim, Verma, & Greiffenstein, 1988;Hudson et al, 2008;Kapur et al, 1988;Moser et al, 1998;Pisani et al, 2000;Ruff & Volpe, 1981;Yamada et al, 2003).…”

Therefore, several mechanisms have been proposed: a special form of topographical disorientation (Fisher, 1982), severe memory deficit (Staton et al, 1982), or combinations of cognitive impairments, e.g., an abnormal sense of familiarity with an unknown environment combined with altered memory (Pisani et al, 2000) (Hakim et al, 1988;Moser et al, 1998), mixed executive and visuospatial disorders (Benson et al, 1976), an impairment of memory associated with executive failures (Yamada et al, 2003), or the combination of a dysexecutive syndrome with memory and visuospatial deficits (Budson et al, 2000;Benson & Stuss, 1990;Kapur et al, 1988;Patterson & Mack, 1985;Ruff & Volpe, 1981).…”
