ICD-10: G47.25

Circadian rhythm sleep disorder, jet lag type, is classified under the ICD-10 code G47.25. This disorder is primarily associated with the disruption of the body's internal clock, which regulates sleep-wake cycles, due to rapid travel across multiple time zones. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description

Definition

Circadian rhythm sleep disorder, jet lag type, occurs when an individual's circadian rhythms are misaligned with the external environment, particularly after long-distance travel. This misalignment can lead to significant sleep disturbances, including difficulty falling asleep, maintaining sleep, and waking up at the desired time.

Symptoms

Individuals experiencing jet lag may report a variety of symptoms, including:
- Insomnia: Difficulty falling asleep or staying asleep.
- Excessive daytime sleepiness: Feeling unusually tired during the day.
- Fatigue: General lack of energy and motivation.
- Mood disturbances: Increased irritability, anxiety, or depressive symptoms.
- Cognitive impairments: Difficulty concentrating or memory issues.

These symptoms typically arise after traveling across two or more time zones and can last several days as the body adjusts to the new time zone.

Diagnosis

Diagnosis of G47.25 is primarily clinical and involves:
- Patient history: Assessing travel history, sleep patterns, and symptom duration.
- Sleep diaries: Keeping a record of sleep-wake times and associated symptoms.
- Exclusion of other sleep disorders: Ensuring that symptoms are not attributable to other conditions such as insomnia or sleep apnea.

Treatment

Management of jet lag typically includes:
- Light therapy: Exposure to bright light at specific times to help reset the circadian clock.
- Melatonin supplementation: Taking melatonin can help regulate sleep-wake cycles, particularly when taken before bedtime in the new time zone.
- Sleep hygiene practices: Encouraging good sleep habits, such as maintaining a consistent sleep schedule and creating a conducive sleep environment.
