Sleep Medicine Reviews
|October 11, 2008
Summary
This review details circadian rhythm sleep disorders and their treatments. It emphasizes estimating circadian phase through patient history to optimize bright light and melatonin therapies, improving patient outcomes.
Area of Science:
- Sleep Medicine
- Chronobiology
- Internal Medicine
Background:
- Circadian rhythm sleep disorders (CRSDs) are prevalent in clinical settings.
- Common CRSDs include delayed/advanced sleep phase, free-running, irregular sleep-wake rhythms, jet lag, and shift work disorders.
- Effective treatments like bright light therapy and melatonin are available but require precise timing.
Observation:
- Objective measures for circadian phase (e.g., core body temperature, melatonin rhythms) are rarely used in clinical practice.
- Accurate circadian phase estimation is crucial for effective treatment timing.
- Mismatched treatment timing can exacerbate CRSD symptoms.
Findings:
- This review focuses on estimating circadian phase using patient history, a practical clinical approach.
- Recommendations are provided for timing bright light and melatonin interventions based on estimated circadian phase.
- The goal is to provide clinicians with simple, actionable strategies for managing CRSDs.
Implications:
- Facilitating accurate circadian phase assessment in routine clinical practice.
- Enhancing the efficacy of bright light and melatonin treatments for CRSDs.
- Improving patient management and outcomes for individuals with circadian rhythm sleep disorders.

01:19Management of Insomnia
The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...
02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

01:15Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

01:11Understanding Sleep
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

01:24Sleep-Wake Cycles
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
