Ewers, Michael; Zhong, Zhenyu; Burger, Katharina; Wallin, Anders; Blennow, Kaj; Teipel, Stefan J.; Shen, Yong; Hampel, Harald – Brain, 2008
The Apolipoprotein (ApoE) [epsilon]4 allele is a major genetic risk factor of Alzheimer's disease, and may affect the production of amyloid beta (A[beta][subscript 1-42]). Recently, we have shown that [beta]-secretase (BACE 1) activity can be reliably detected within the brain and human CSF. Here, we have examined an association between the ApoE…

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…

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…
