Thanks. The best way to evaluate this is the prospective analysis, adjusted for control variables. The confidence interval on that hazard ratio includes 1.00, so the null hypothesis that there is no difference stands. For the cross-sectional analysis, essential tremor was associated with dementia, but it gives no information as to whether ET increases risk for later dementia vs. dementia raises risk of ET. Finally, the criteria used for dementia diagnosis are the psychiatric criteria from 4 DSM editions ago, though the criteria have been revised and updated numerous times by neurologists and other neuroscientists (i.e. those who work with essential tremor). At least the sample was community-based instead of clinic-based.
