Patient and caregiver outcomes after 6 +/- 1.5-months of rivastigmine therapy for mild-to-moderate Alzheimer's disease: the Belgian FExT study.

Objective: Despite response variability, cholinesterase inhibitors are recommended in mild to moderate Alzheimer's disease. Dose titration is common; however randomized controlled trials (RCTs) have mainly investigated fixed-dose regimens. We examined practice patterns and outcomes of 6 +/- 1.

A randomized double-blind placebo-controlled trial of thioctic acid in migraine prophylaxis.

Background: Impaired mitochondrial phosphorylation potential may play a role in migraine pathogenesis. Metabolic enhancers, such as riboflavin or coenzyme Q, are effective in migraine prophylaxis and quasi-devoid of adverse effects. Thioctic acid (-lipoic acid) is another substance known to enhance energy metabolism in mitochondria and to be beneficial in diabetic neuropathy.

A unique episode of REM sleep behavior disorder triggered during surgery for Parkinson's disease.

REM sleep behavior disorder (RBD) is characterized by vigorous movements during REM sleep. Here, the authors report the case of a patient who presented such a disorder immediately after the implantation of the definitive electrode for left subthalamic stimulation. Interestingly, this was and has remained a unique episode in his medical history.
