Summary
Migraine sufferers often have early or late chronotypes and experience more "languid" and "rigid" responses to circadian rhythm changes. Many migraine attacks occur in the early morning, suggesting chronobiology
Area of Science:
- Chronobiology
- Neurology
- Sleep Medicine
Background:
- Migraine attacks may follow circadian patterns linked to individual chronotypes.
- Understanding chronotype and circadian rhythm stability in migraine is crucial for pathophysiology insights.
Purpose of the Study:
- To evaluate and correlate individual chronotypes, circadian rhythm stability, and attack timing in a large migraine cohort.
- To compare chronobiological patterns between migraineurs and non-headache controls.
Main Methods:
- Assessed chronotype distribution using the Munich Chronotype Questionnaire in 2875 migraineurs and 200 controls.
- Measured circadian rhythm amplitude and stability via the Circadian Type Inventory.
- Analyzed circadian timing of migraine attacks and correlated with chronotype and rhythm stability using regression models.
Main Results:
- Migraineurs exhibited higher prevalence of early and late chronotypes compared to controls.
- Migraineurs, especially those with frequent attacks, reported increased languidity and rigidity concerning circadian rhythm changes.
- Over 40% of migraineurs reported early morning attack onset.
Conclusions:
- Migraine patients deviate from normal chronotypes more frequently than controls.
- Circadian rhythm disruptions significantly impact migraineurs, manifesting as increased languidity and rigidity.
- The prevalence of early morning attacks suggests a significant role for chronobiological mechanisms in migraine pathophysiology.

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...

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...

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...

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

604
Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

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).
