An 8-week, randomized, double-blind, placebo-controlled, 2-center study.
Since ancient times, it has been said that drinking green tea brings relaxation. The substance that is responsible for a sense of relaxation, is theanine. Theanine is a unique amino acid found almost solely in tea plants and the main component responsible for the exotic taste of 'green' tea. It was found that L-theanine administered intraperitoneally to rats reached...
Abstract The study was focused on the clinico-pharmacological analysis of differences between subjective and objective assessment of the effects of antiasthenic drug ladasten and placebo effects in patients with neurasthenia with different individual patterns manifested in their EEG alpha rhythms and MMPI findings. It is established that, in patients with neurasthenia characterized by reduced EEG alpha activity combined with...
Abstract OBJECTIVES: The purpose of the present study was to test whether the repeated practice of self-regulation could improve regulatory strength over time.
Abstract INTRODUCTION: The incidence of depression is increasing worldwide. Much is still unknown about the possible role of magnesium in depression prevention and treatment. Magnesium has an effect on biological and transduction pathways implicated in the pathophysiology of depression. The possible role of magnesium in depression prevention and treatment remains unclear. OBJECTIVES: We systematically reviewed the possible links between...
AbstractThe aim of this study was to assess the influence of drug therapy (DT) with pramiracetam and memory training (MT), each alone, and in combination (DTMT), on both the objective memory and metamemory performance. Thirty-five non-depressed, non-demented healthy elderly (mean age: 64.8 years) with objective (story recall) and/or subjective (cognitive difficulties scale) memory loss were randomly included in four...
Abstract STUDY OBJECTIVES: To investigate the efficacy of melatonin compared to placebo in improving sleep parameters in patients with primary sleep disorders. DESIGN: PubMed was searched for randomized, placebo-controlled trials examining the effects of melatonin for the treatment of primary sleep disorders. Primary outcomes examined were improvement in sleep latency, sleep quality and total sleep time. Meta-regression was performed...
Abstract In 2010 the European Medicines Agency withdrew the indication of modafinil for the treatment of obstructive sleep apnea, shift work sleep disorder and for idiopathic hypersomnia (IH). In uncontrolled studies, modafinil has been reported to be efficacious in the treatment of sleep disorders. We therefore performed a randomized, placebo-controlled study with the aim of proving the efficacy of...
Abstract: Drinking alcohol in moderation is often considered a health-conscious behavior, associated with improved cardiovascular and brain health. However, "moderate" amounts of alcohol include drinking 3-4 alcohol beverages in a day, which is closer to binge drinking and may do more harm than good. Here we examined how daily drinking of moderate-high alcohol alters the production of new neurons...
