Insomnia is a common sleep disorder defined by night time and daytime symptoms. Night time symptoms include persistent difficulties falling and/or staying asleep and/or non-restorative sleep. Daytime symptoms of insomnia can include diminished sense of well being, compromised functioning such as difficulties with concentration and memory, fatigue, concerns and worries about sleep. The diagnosis is made when the symptoms persist for at least 1 month and insomnia is considered chronic if it persists for at least 6 months. Nearly one in 10 adults in the United States suffers from insomnia.
It is important to realize that not everyone who has problems sleeping has insomnia. The word persistent is emphasized because many people occasionally experience disturbed sleep at night but their problem is transient.
Clinical trials are research studies that evaluate a new medical approach, device, drug, or other treatment. As a Stanford Health Care patient, you may have access to the latest, advanced clinical trials.
Open trials refer to studies currently accepting participants. Closed trials are not currently enrolling, but may open in the future.
