Al years. Their function, like that in the Parkinson’s Progression Markers Initiative along with the Parkinson’s Illness Biomarkers Program , must mark a significant shift in the good quality of studies of biomarkers for disease progression, and hopefully cause advances in this important field. volume and complete brain volume as biomarkers of disease progression in Alzheimer’s illness does seem to become merited. As in our prior systematic in PD, we identified methodological, statistical and reporting flaws in research examining illness progression in Alzheimer’s disease. Our methodological guidelines should really hopefully supply a superior likelihood of making progress within this location, and we would value feedback on them.
