Rivastigmine for Intensive Care Unit (ICU) Delirium
Delirium in Intensive Care (IC) patients is a frequent disorder. The aim of this study is to investigate whether treatment of delirium in the ICU with rivastigmine added to haloperidol shortens the duration of delirium in comparison to placebo added to the treatment with haloperidol.
Objective: To study whether rivastigmine added to treatment with haloperidol shortens the duration of delirium in ICU patients and reduces costs.
Study design: Multicentre, double-blind, randomized controlled trial. Study population: Consecutive adult ICU patients with delirium according to the CAM-ICU.
Intervention: Increasing dosage of rivastigmine or placebo as add-on medication.
Primary study parameters: Duration of delirium. Secondary study parameters: Delirium severity, length of ICU and hospital stay, functional status and mortality after 3 months.
Sample size: 440 patients will be included. Economic evaluation: includes a comparison of direct and indirect medical costs.
Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Burden: questionnaires (duration: 30 minutes). Risk: possible exposure to drug not indicated for the disorder. Benefit: possible treatment with according to experts possible beneficial drug. Consideration: The investigators of this study believe that the burden and risk do not exceed the expected benefit.
Allocation: Randomized, Control: Placebo Control, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Alcohol Withdrawal Delirium
An acute organic mental disorder induced by cessation or reduction in chronic alcohol consumption. Clinical characteristics include CONFUSION; DELUSIONS; vivid HALLUCINATIONS; TREMOR; agitation; insomnia; and signs of autonomic hyperactivity (e.g., elevated blood pressure and heart rate, dilated pupils, and diaphoresis). This condition may occasionally be fatal. It was formerly called delirium tremens. (From Adams et al., Principles of Neurology, 6th ed, p1175)
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
A disorder characterized by CONFUSION; inattentiveness; disorientation; ILLUSIONS; HALLUCINATIONS; agitation; and in some instances autonomic nervous system overactivity. It may result from toxic/metabolic conditions or structural brain lesions. (From Adams et al., Principles of Neurology, 6th ed, pp411-2)

The purpose of this study is to determine whether Rivastigmine is effective for the prevention of postoperative delirium in patients undergoing cardiac surgery.
The study is a 24-week prospective, double blind, randomized, placebo-controlled pilot study of 9 mg / day Rivastigmine in patients with Vascular Cognitive Impairment Not Dementia (CIND) t...
This is a prospective, multicenter, open-label study. Following screening and baseline assessments, eligible patients will be switched to rivastigmine and will enter the 16 week run-in ri...
To study the effects of treatment with rivastigmine on craving produced by experimental administration of methamphetamine.
Background: Rivastigmine patches provide similar efficacy to rivastigmine capsules with a lower incidence of gastrointestinal side effects in patients with probable Alzheimer's disease (AD). Methods:...
Aim: The cholinesterase inhibitor rivastigmine is available in both oral and transdermal forms. The efficacy of oral rivastigmine appears to be dose-dependent. The current analysis investigates the...
BACKGROUND: Disturbance in the metabolism of tryptophan and tryptophan-derived compounds (e.g., melatonin) may have a role in the pathogenesis of delirium. OBJECTIVE: To evaluate the efficacy of low d...
