Comparative Study
Motor symptoms in 100 patients with delirium versus control subjects: comparison of subtyping methods.
Different motor presentations of delirium may represent clinically meaningful subtypes. ⋯ Motor disturbances are common in delirium, although whether they represent clinical subtypes is confounded by methodological issues. New motor subtyping methods are needed that are validated in other medical populations, use matched control subjects, and have higher sensitivity and specificity for pure motor features.
