Background: Insomnia often responds to the orexin receptor antagonist suvorexant. This study aimed to evaluate the efficacy and adverse events of suvorexant for Chinese patients with primary insomnia over 6 months. Methods: A total of 120 patients with primary insomnia were assigned randomly to two groups that received placebo or suvorexant (40 mg) for 6 months. The primary outcomes were the total sleep time (sTST), time to sleep onset (sTSO), and sleep quality (sQUAL). The secondary outcomes were the Insomnia Severity Index (ISI) score and adverse events. Results: A total of 111 patients completed the study and all of them were included in the final analysis. Suvorexant showed greater efficacy than the placebo in enhancing sTST, sTSO, sQUAL and ISI score at months 1 and 6. Serious adverse events were documented in 2 patients (3.3%) in the suvorexant group and 1 patients (1.7%) in the placebo group. The most common adverse event was somnolence, which occurred in 7 patients (11.7%) in the suvorexant group and 2 patients (3.3%) in the placebo group. No death related to suvorexant treatment was recorded. Conclusions: Suvorexant was efficacious and well-tolerated in a group of Chinese patients with primary insomnia over 6 months.
Sleep Initiation and Maintenance Disorders

Sleep can be easily disrupted by variety of conditions. Most of medical illnesses could be a primary condition causing secondary insomnia. The common underlying mechanism of secondary insomnia is presumed to be stress effects on sleep. The assessment and treatment of secondary insomnia are often complicated. Establishing an causal inference between primary condition and insomnia is the key to assessment. However, it can be difficult even for experienced clinicians due to diagnostic ambiguity of secondary insomnia. Therefore, through medical evaluation and integrative understanding of primary condition is essential to manage secondary insomnia properly. Although treatment have been usually focused on the primary medical illnesses per se, nonpharmacologic interventions, such as sleep hygiene, might be effective in many cases.

Objective: This paper aims to explore the possibility of using motivational interviewing (MI) as a therapy for insomnia patients. Methods: We reviewed the current practice guidelines for insomnia, and noted the issues pertaining to types of treatment, notably CBT-I. We also reviewed some studies which seem to suggest that MI treats insomnia. Results: MI is a proven technique for other psychiatric illnesses. There are currently not many studies done evaluating the efficacy of MI on insomnia. Of those published studies, they are either underpowered to draw any firm conclusions, or it is limited to a particular age group. Conclusion: There seems to be promise in the area of MI on insomnia. Given the paucity of data in this area, more research with bigger group of study participants are needed to fully conclude the effectiveness of this treatment.

OBJECTIVES: The purpose of this study was to assess the difference of subjective daytime sleepiness level between primary insomnia patients and healthy control subjects. We also investigated the relationship between subjective daytime sleepiness level and variables of nocturnal polysomnograghic sleep architecture of insomnia patients. METHOD: Total subjects were 87 patients with primary insomnia diagnosed with polysomnography and 88 normal controls. The daytime sleepiness level in each group was measured by Korean version of Epworth Sleepiness Scale (ESS). The correlations of ESS score and nocturnal polysomnographic variables were calculated in the patient group. RESULTS: Patients with insomnia had the lower ESS scores than the control group. In patients group, the ESS score showed significant negative correlations with total sleep time, sleep efficiency%, and stage 2 sleep time%. The ESS score also showed significant positive correlations with number of awakenings, number of awakenings more than 2 minutes, and wake after sleep onset time. CONCLUSIONS: Insomnia patients showed lower level of subjective daytime sleepiness that may indicate their higher alertness comparing to control subjects. Daytime sleepiness of patients with insomnia was associated with polysomnographic variables including total sleep time, sleep efficiency%, stage 2 sleep time% and disrupted continuity of nocturnal sleep.

Two chronic insomnia cases are presented to illustrate the clinical application of hypnotic techniques. The treatment procedures, which incorporate the demand characteristics of the therapeutic setting, positive expectancies, a reduction in physiological arousal, and a reduction of excessive cognitive activity are discussed.
