McKee, Ann C.; Stein, Thor D.; Nowinski, Christopher J.; Stern, Robert A.; Daneshvar, Daniel H.; Alvarez, Victor E.; Lee, Hyo-Soon; Hall, Garth; Wojtowicz, Sydney M.; Baugh, Christine M.; Riley, David O.; Kubilus, Caroline A.; Cormier, Kerry A.; Jacobs, Matthew A.; Martin, Brett R.; Abraham, Carmela R.; Ikezu, Tsuneya; Reichard, Robert Ross; Wolozin, Benjamin L.; Budson, Andrew E.; Goldstein, Lee E.; Kowall, Neil W.; Cantu, Robert C. – Brain, 2013
Chronic traumatic encephalopathy is a progressive tauopathy that occurs as a consequence of repetitive mild traumatic brain injury. We analysed post-mortem brains obtained from a cohort of 85 subjects with histories of repetitive mild traumatic brain injury and found evidence of chronic traumatic encephalopathy in 68 subjects: all males, ranging…

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…

Intellectual Enrichment Is Linked to Cerebral Efficiency in Multiple Sclerosis: Functional Magnetic Resonance Imaging Evidence for Cognitive Reserve
Peer reviewed Peer reviewed

Sumowski, James F.; Wylie, Glenn R.; DeLuca, John; Chiaravalloti, Nancy – Brain, 2010
The cognitive reserve hypothesis helps to explain the incomplete relationship between brain disease and cognitive status in people with neurologic diseases, including Alzheimer's; disease and multiple sclerosis. Lifetime intellectual enrichment (estimated with education or vocabulary knowledge) lessens the negative impact of brain disease on…

Language Processing within the Striatum: Evidence from a PET Correlation Study in Huntington's Disease
Peer reviewed Peer reviewed

Teichmann, Marc; Gaura, Veronique; Demonet, Jean-Francois; Supiot, Frederic; Delliaux, Marie; Verny, Christophe; Renou, Pierre; Remy, Philippe; Bachoud-Levi, Anne-Catherine – Brain, 2008
The role of sub-cortical structures in language processing, and more specifically of the striatum, remains controversial. In line with psycholinguistic models stating that language processing implies both the recovery of lexical information and the application of combinatorial rules, the striatum has been claimed to be involved either in the…

The Distinct Cognitive Syndromes of Parkinson's Disease: 5 Year Follow-Up of the CamPaIGN Cohort
Peer reviewed Peer reviewed

Williams-Gray, Caroline H.; Evans, Jonathan R.; Goris, An; Foltynie, Thomas; Ban, Maria; Robbins, Trevor W.; Brayne, Carol; Kolachana, Bhaskar S.; Weinberger, Daniel R.; Sawcer, Stephen J.; Barker, Roger A. – Brain, 2009
Cognitive abnormalities are common in Parkinson's disease, with important social and economic implications. Factors influencing their evolution remain unclear but are crucial to the development of targeted therapeutic strategies. We have investigated the development of cognitive impairment and dementia in Parkinson's disease using a longitudinal…

Oculomotor Function in Frontotemporal Lobar Degeneration, Related Disorders and Alzheimer's Disease
Peer reviewed Peer reviewed

Garbutt, Siobhan; Matlin, Alisa; Hellmuth, Joanna; Schenk, Ana K.; Johnson, Julene K.; Rosen, Howard; Dean, David; Kramer, Joel; Neuhaus, John; Miller, Bruce L.; Lisberger, Stephen G.; Boxer, Adam L. – Brain, 2008
Frontotemporal lobar degeneration (FTLD) often overlaps clinically with corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP), both of which have prominent eye movement abnormalities. To investigate the ability of oculomotor performance to differentiate between FTLD, Alzheimer's disease, CBS and PSP, saccades and smooth pursuit were…

Clinical, Imaging and Pathological Correlates of a Hereditary Deficit in Verb and Action Processing
Peer reviewed Peer reviewed

Bak, Thomas H.; Yancopoulou, Despina; Nestor, Peter J.; Xuereb, John H.; Spillantini, Maria G.; Pulvermuller, Friedemann; Hodges, John R. – Brain, 2006
Selective verb and noun deficits have been observed in a number of neurological conditions and their occurrence has been interpreted as evidence for different neural networks underlying the processing of specific word categories. We describe the first case of a familial occurrence of a selective deficit of verb processing. Father (Individual I)…

What's in a Name: Voxel-Based Morphometric Analyses of MRI and Naming Difficulty in Alzheimer's Disease, Frontotemporal Dementia and Corticobasal Degeneration
Direct linkDirect link
Grossman, Murray; McMillan, Corey; Moore, Peachie; Ding, Lijun; Glosser, Guila; Work, Melissa; Gee, James – Brain, 2004
Confrontation naming is impaired in neurodegenerative conditions like Alzheimer's disease (AD), frontotemporal dementia (FTD) and corticobasal degeneration (CBD). Some behavioural observations suggest a common source of impaired naming across these patient groups, while others find partially unique patterns of naming difficulty. We hypothesized…

Anti-HIV Drugs Decrease the Expression of Matrix Metalloproteinases in Astrocytes and Microglia

Liuzzi, G. M.; Mastroianni, C. M.; Latronico, T.; Mengoni, F.; Fasano, A.; Lichtner, M.; Vullo, V.; Riccio, P. – Brain, 2004
The introduction of potent antiretroviral drugs for the treatment of patients with human immunodeficiency virus (HIV) infection has dramatically reduced the prevalence of HIV-associated neurological disorders. Such diseases can be mediated by proteolytic enzymes, i.e. matrix metalloproteinases (MMPs) and, in particular gelatinases, released from…
