ABSTRACT This systematic literature review evaluated the risks of using benzodiazepine medications for more than 3 months in adults with chronic insomnia. Chronic insomnia is defined as ongoing dissatisfaction with sleep quantity or quality, causing significant distress and impaired functioning during the day.

The N-soliton solutions of the n-component generalized Sasa-Satsuma system: Riemann-Hilbert method
Using the Riemann-Hilbert method, the paper systematically investigates the n-component generalized Sasa-Satsuma system. By utilizing the Tu scheme, we systematically construct the n-component generalized Sasa-Satsuma integrable hierarchy, and obtain the

THE RIEMANN PROBLEM FOR APPELL'S F4
Appell's system of differential equations of type \[ (F_ 4): \begin{cases} x(1- x) r-y^ 2 t-2xys+ \{\gamma- (\alpha+\beta+1) x\} p-(\alpha+ \beta+1) yq- \alpha\beta z=0\\ y(1-y)t- x^ 2 r-2xys+ \{\gamma'- (\alpha+\beta+1) y\} q-(\alpha+ \beta+ 1)xp- \alpha\beta z=0 \end{cases} \] has singularities along \(S:\{x=0\}\cup \{y=0\}\cup \{(x-y)^ 2- 2(x+y)+1 ...

ABSTRACT Cognitive behavioural therapy for insomnia (CBT‐I) is recommended as first‐line treatment for insomnia disorder. However, around 25% of the patients do not respond to the treatment, and only 40% achieve full remission. The current study investigates the therapeutic potential of light therapy as an add‐on to CBT‐I.

ABSTRACT Sleep disturbances are prevalent after acquired brain injury and negatively affect quality of life. Sensory hypersensitivity may cause or exacerbate sleep disturbances, yet evidence on this relationship after acquired brain injury is lacking. The aim of this study was to investigate the hypothesised positive relationship between the severity ...

A nonlocal problem for fourth order hyperbolic equations with multiple characteristic
In this paper, we study fourth order differential equations with multiple characteristics and dominated low terms. We prove the existence and uniqueness of a Riemann function for this equation, and then provide an integral representation of the general ...

How Mental Concepts Shape Sleep: Introducing the Mental Concept Reactivation Hypothesis of Sleep
ABSTRACT Sleep problems affect a substantial proportion of individuals, and negative thoughts, rumination, and worry are considered key factors underlying persistence and severity. While extensive research has examined how these states disrupt sleep before falling asleep, much less is known about how mental concepts, including thoughts, expectations ...

The Development of the European Sleep Questionnaire A New Patient‐Reported Outcome Measure
ABSTRACT Sleep medicine relies on patient‐reported outcome measures (PROMs) to complement clinical interviews and objective sleep tests. Available sleep questionnaires focus on isolated symptoms or single disorders, limiting their ability to capture the complexity of sleep conditions. Also, many PROMs remain poorly validated.
