Education, the Brain and Dementia: Neuroprotection or Compensation?
Peer reviewed Peer reviewed

Brayne, Carol; Ince, Paul G.; Keage, Hannah A. D.; McKeith, Ian G.; Matthews, Fiona E.; Polvikoski, Tuomo; Sulkava, Raimo – Brain, 2010
The potential protective role of education for dementia is an area of major interest. Almost all older people have some pathology in their brain at death but have not necessarily died with dementia. We have explored these two observations in large population-based cohort studies (Epidemiological Clinicopathological Studies in Europe; EClipSE) in…

Bagnato, Francesca; Hametner, Simon; Yao, Bing; van Gelderen, Peter; Merkle, Hellmut; Cantor, Fredric K.; Lassmann, Hans; Duyn, Jeff H. – Brain, 2011
Previous authors have shown that the transverse relaxivity R[subscript 2][superscript *] and frequency shifts that characterize gradient echo signal decay in magnetic resonance imaging are closely associated with the distribution of iron and myelin in the brain's white matter. In multiple sclerosis, iron accumulation in brain tissue may reflect a…

Samaranch, Lluis; Lorenzo-Betancor, Oswaldo; Arbelo, Jose M.; Ferrer, Isidre; Lorenzo, Elena; Irigoyen, Jaione; Pastor, Maria A.; Marrero, Carmen; Isla, Concepcion; Herrera-Henriquez, Joanna; Pastor, Pau – Brain, 2010
Phosphatase and tensin homolog-induced putative kinase 1 gene mutations have been associated with autosomal recessive early-onset Parkinson's disease. To date, no neuropathological reports have been published from patients with Parkinson's disease with both phosphatase and tensin homolog-induced putative kinase 1 gene copies mutated. We analysed…

Cognitive Reserve and Alzheimer's Disease Biomarkers Are Independent Determinants of Cognition
Peer reviewed Peer reviewed

Vemuri, Prashanthi; Weigand, Stephen D.; Przybelski, Scott A.; Knopman, David S.; Smith, Glenn E.; Trojanowski, John Q.; Shaw, Leslie M.; Decarli, Charlie S.; Carmichael, Owen; Bernstein, Matt A.; Aisen, Paul S.; Weiner, Michael; Petersen, Ronald C.; Jack, Clifford R., Jr. – Brain, 2011
The objective of this study was to investigate how a measure of educational and occupational attainment, a component of cognitive reserve, modifies the relationship between biomarkers of pathology and cognition in Alzheimer's disease. The biomarkers evaluated quantified neurodegeneration via atrophy on magnetic resonance images, neuronal injury…

Genes for Hereditary Sensory and Autonomic Neuropathies: A Genotype-Phenotype Correlation
Peer reviewed Peer reviewed
Direct linkDirect link
Rotthier, Annelies; Baets, Jonathan; De Vriendt, Els; Jacobs, An; Auer-Grumbach, Michaela; Levy, Nicolas; Bonello-Palot, Nathalie; Kilic, Sara Sebnem; Weis, Joachim; Nascimento, Andres; Swinkels, Marielle; Kruyt, Moyo C.; Jordanova, Albena; De Jonghe, Peter; Timmerman, Vincent – Brain, 2009
Hereditary sensory and autonomic neuropathies (HSAN) are clinically and genetically heterogeneous disorders characterized by axonal atrophy and degeneration, exclusively or predominantly affecting the sensory and autonomic neurons. So far, disease-associated mutations have been identified in seven genes: two genes for autosomal dominant ("SPTLC1"…

Neutralizing Antibodies against IFN-[Beta] in Multiple Sclerosis: Antagonization of IFN-[Beta] Mediated Suppression of MMPs
Direct linkDirect link
Gilli, Francesca; Bertolotto, Antonio; Sala, Arianna; Hoffmann, Francine; Capobianco, Marco; Malucchi, Simona; Glass, Tracy; Kappos, Ludwig; Lindberg, Raija L. P.; Leppert, David – Brain, 2004
Neutralizing antibodies (NAb) against interferon-[Beta] (IFN-Beta) develop in about a third of treated multiple sclerosis patients and are believed to reduce therapeutic efficacy of IFN-[Beta] on clinical and MRI measures. The expression of the interferon acute-response protein, myxovirus resistance protein A (MxA) is a sensitive measure of the…
