TL;DR: The first results of the beam spin asymmetry measured in the reaction e + p -> e+ p + p + gamma at a beam energy of 4.25 GeV were reported in this paper.
Journal ArticleDOI
Neuropsychiatric outcomes of stroke.
Maree L. Hackett,Maree L. Hackett,Sebastian Köhler,John T. O'Brien,John T. O'Brien,Gillian Mead +5 more
TL;DR: The most common neuropsychiatric outcomes of stroke are depression, anxiety, fatigue, and apathy, which each occur in at least 30% of patients and have substantial overlap of prevalence and symptoms.
Journal ArticleDOI
A magnetic resonance imaging study of white matter lesions in depression and Alzheimer's disease.
TL;DR: An association between DWML and depression and PVL and Alzheimer's disease is supported and the increase with DWML that occurs with ageing may predispose some elderly subjects to depression.
