Evidence for grey matter MTR abnormality in minimally disabled patients with early relapsing-remitting multiple sclerosis.
To establish whether magnetisation transfer ratio (MTR) histograms are sensitive to change in normal appearing grey matter (NAGM) in early relapsing-remitting multiple sclerosis (RRMS) in the absence of significant disability; and to assess whether grey or white matter MTR measures are associated with clinical measures of impairment in early RRMS METHODS: 38 patients were studied (mean disease duration 1.9 years (range 0.5 to 3.7); median expanded disability status scale (EDSS) 1.5 (0 to 3)), along with 35 healthy controls. MTR was determined from proton density weighted images with and without MT presaturation. SPM99 was used to generate normal appearing white matter (NAWM) and NAGM segments of the MTR map, and partial voxels were minimised with a 10 pu threshold and voxel erosions. Mean MTR was calculated from the tissue segments. Atrophy measures were determined using a 3D fast spoiled gradient recall sequence from 37 patients and 17 controls. ⋯ In early RRMS, grey matter MTR abnormality is apparent. The correlation with mild clinical impairment (in this essentially non-disabled cohort) suggests that NAGM MTR could be a clinically relevant surrogate marker in therapeutic trials.

The generic 15D instrument is valid and feasible for measuring health related quality of life in Parkinson's disease.
To test the validity and feasibility of the generic 15D health related quality of life (HRQoL) instrument in Parkinson's disease (PD) and compare parkinsonian patients with the general population. Much effort has gone into developing disease specific HRQoL measures for PD, but only generic measures allow comparisons with the general population. New HRQoL tools are needed for PD because earlier ones have low feasibility in elderly patients. ⋯ 15D is a valid, feasible, and sensitive tool to assess quality of life in PD. PD has a major impact on HRQoL, which is related to disease progression. Mobility, eating, speech, and sexual functions are most affected. The ADL measure of the UPDRS and the 15D provide an easily assessable view of HRQoL in PD.
