Detailed Description
To demonstrate the influence of the herbal combination preparation Neurapas® balance on the objective sleep structure in comparison with placebo. A further aim was to investigate whether treatment with Neurapas® balance versus placebo brings about an improvement in attention and well-being and whether these changes are related to the improvement in the sleep structure.
- Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in continuity of sleep?
- Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in sleep architecture, especially an increase in deep sleep?
- Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in morning attentional performance?
- Does the administration of 3 x 2 Neurapas® balance tablets over a period of three days vs. placebo lead to an improvement in morning well-being?
