Randomized Controlled Trial
Rivastigmine in the treatment of delirium in older people: a pilot study.
Delirium is common in the elderly and is associated with high mortality and negative health outcomes. Reduced activity in the cholinergic system has been implicated in the pathogenesis of delirium. Cholinesterase inhibitors, which increase cholinergic activity, may therefore be beneficial in the treatment of delirium. ⋯ The numbers of patients who screened positive for delirium was very small and as a result the sample size was too small to make any meaningful inferences about treatment of delirium. Despite the small numbers included in the study, there are some indicators that rivastigmine may be safe and effective in treating delirium.
