Multicenter clinical placebo‐controlled study with acetyl‐l‐carnitine (LAC) in the treatment of mildly demented elderly patients

Abstract
Acetyl‐l‐carnitine (LAC) was administered for 3 months, 2 g/daily, to 30 elderly patients with mild mental deterioration. Results were compared to those of a homogeneous control group of 28 patients treated with placebo. The study was carried out according to a double‐blind, randomized methodology. A complete battery of rating scales and psychometric tests was used for for evaluating the modifications induced by either drug or placebo. The statistical evaluation of results showed a sufficient clear efficacy of the drug studied: results from patients on LAC were frequently different from those receiving placebo. Therefore, LAC must be taken into consideration as a useful drug for the global treatment of demented elderly patients.
