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…

Saykin, Andrew J.; Wishart, Heather A.; Rabin, Laura A.; Flashman, Laura A.; McHugh, Tara L.; Mamourian, Alexander C.; Santulli, Robert B. – Brain, 2004
Cholinesterase inhibitors positively affect cognition in Alzheimer's disease (AD) and other conditions, but no controlled functional MRI studies have examined where their effects occur in the brain. We examined the effects of donepezil hydrochloride (Aricept[Registered sign]) on cognition and brain activity in patients with amnestic mild cognitive…

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…

Pinto, Serge; Thobois, Stephane; Costes, Nicolas; Le Bars, Didier; Benabid, Alim-Louis; Broussolle, Emmanuel; Pollak, Pierre; Gentil, Michele – Brain, 2004
In Parkinson's disease, functional imaging studies during limb motor tasks reveal cerebral activation abnormalities that can be reversed by subthalamic nucleus (STN) stimulation. The effect of STN stimulation on parkinsonian dysarthria has not, however, been investigated using PET. The aim of the present study was to evaluate the effect of STN…

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…
