Brain age in bipolar disorders: Effects of lithium treatment:
Holly Van Gestel,Katja Franke,Joanne Petite,Claire Slaney,Julie Garnham,Carl A. Helmick,Kyle Johnson,Rudolf Uher,Martin Alda,Martin Alda,Tomas Hajek,Tomas Hajek +11 more
TL;DR: The findings support the neuroprotective effects of Li, which were sufficiently pronounced to affect a complex, multivariate measure of brain structure, and may generalize beyond bipolar disorders, to neurodegenerative disorders.

Neural Coding of Movement Direction in the Healthy Human Brain
Christopher D. Cowper-Smith,Esther Yuet Ying Lau,Carl A. Helmick,Gail A. Eskes,David A. Westwood +4 more
TL;DR: It is shown that PD coding does exist in regions of the human motor system that are homologous to those observed in non-human primates and adaptation of the BOLD signal in M1, PMC, SMA, and cerebellum is shown.

Neural and Behavioral Outcomes Differ Following Equivalent Bouts of Motor Imagery or Physical Practice.
Sarah N. Kraeutner,Alexandra Stratas,Jennifer L McArthur,Carl A. Helmick,David A. Westwood,Shaun G. Boe +5 more
TL;DR: By directly comparing brain activity and behavioral outcomes after equivalent training through MI versus PP, this work provides unique knowledge regarding the neural mechanisms underlying learning through MI.

Effects of Vascular Comorbidity on Cognition in Multiple Sclerosis Are Partially Mediated by Changes in Brain Structure
Ruth Ann Marrie,Ronak Patel,Chase R. Figley,Jennifer Kornelsen,James M. Bolton,Lesley A. Graff,Erin L. Mazerolle,Carl A. Helmick,Md. Nasir Uddin,Teresa D. Figley,James J. Marriott,Charles N. Bernstein,John D. Fisk +12 more
TL;DR: Vascular comorbidity is associated with lower cognitive function in people with MS and this association is partially mediated via changes in brain macrostructure and microstructure.
Higher Framingham Risk Scores are associated with greater loss of brain volume over time in multiple sclerosis
Ruth Ann Marrie,Ronak Patel,Chase R. Figley,Jennifer Kornelsen,James M. Bolton,Lesley A. Graff,Erin L. Mazerolle,Carl A. Helmick,Christopher O'Grady,Nasir Uddin,James J. Marriott,Charles N. Bernstein,John D. Fisk,Comorbidity +13 more
TL;DR: In this article, the Framingham Risk Score (FRS) was used to evaluate the association between comorbidities associated with increased vascular risk and brain volume changes in multiple sclerosis (MS).
