TL;DR: Mayo Test Drive (MTD) as mentioned in this paper is a web-based platform optimized for remote self-administered assessment that includes a computer adaptive word list memory test (Stricker Learning Span; SLS) and a measure of processing speed (Symbols Test).

TL;DR: In this article , the authors compare different implementations of MATLAB with known NODDI values, in addition to in vivo scans, using simulations with known nodDI values and using the original implementation as the nominally correct one.

TL;DR: In this paper , the mtDNA haplogroup background was investigated for clinical DLB risk and neuropathological disease severity, and a logistic regression model was used to assess associations between haplogroups and risk of DLB versus controls in a case-control analysis.
