TL;DR: It is found that frequently applied thresholds for Pittsburgh compound-B positivity (typically at or above distribution volume ratiohigh and standard uptake value ratiohigh) are overly stringent in defining amyloid positivity.
Journal ArticleDOI
Associations between serum cholesterol levels and cerebral amyloidosis.
Bruce R Reed,Sylvia Villeneuve,Wendy J. Mack,Charles DeCarli,Helena C. Chui,William J. Jagust +5 more
TL;DR: Elevated cerebral Aβ level was associated with cholesterol fractions in a pattern analogous to that found in coronary artery disease, suggesting an important role for cholesterol in Aβ processing.
Journal ArticleDOI
Associations between Alzheimer disease biomarkers, neurodegeneration, and cognition in cognitively normal older people.
Miranka Wirth,Sylvia Villeneuve,Claudia M. Haase,Cindee Madison,Hwamee Oh,Hwamee Oh,Susan M. Landau,Susan M. Landau,Gil D. Rabinovici,Gil D. Rabinovici,Gil D. Rabinovici,William J. Jagust,William J. Jagust +12 more
TL;DR: Accumulation of neurodegenerative abnormalities was related to poor memory and executive functions as well as larger WML volumes but not elevated Pittsburgh compound B retention, confirming that a substantial proportion of cognitively normal older adults harbor neurodegenersation, without Aβ burden.
Journal ArticleDOI
Mild Cognitive Impairment in Moderate to Severe COPD: A Preliminary Study
Sylvia Villeneuve,Véronique Pepin,Shady Rahayel,Josie-Anne Bertrand,Myriam de Lorimier,Amanda Rizk,Catherine Desjardins,Simon Parenteau,François Beaucage,Steve Joncas,Oury Monchi,Jean-François Gagnon +11 more
TL;DR: In this preliminary study, a substantial proportion of patients with COPD were found to have MCI, a known risk factor for dementia, and the MoCA is superior to the MMSE in detecting MCI in patientswith COPD.
Antithrombotic and Thrombolytic Therapy for Valvular Disease
TL;DR: The results on the ESS suggest that daytime sleepiness, which is a central symptom in OSA diagnosis, is probably not a major factor explaining the high frequency of MCI in the COPD cohort.
