Dr Anna Volkmer - Study Recruitment and the Sample Size Jinx

Dr Anna Volkmer, narrates her blog written for Dementia Researcher.

Anna explores the complexities of recruiting participants for intervention trials. She stresses that an inadequately powered study risks irrelevance, highlighting the dilemma of determining the ideal sample size in both main and pilot studies. While conventional wisdom suggests benchmarks for participant numbers, these metrics are rarely straightforward, especially when dealing with a heterogeneous disease like dementia. Anna talks about her research in to Primary Progressive Aphasia, and addresses the added challenges posed by disease rarity and diagnostic ambiguity. She also delves into the ethical concerns and emotional toll of recruiting from a vulnerable population, advocating for better public education on the varied scope of medical research. This blog is a must-read for researchers, ethicists, and anyone interested in the intricacies of conducting ethically responsible and scientifically robust clinical trials.
