Persistent sleep problems can affect concentration, mood, safety, and overall quality of life. A specialized sleep center can help determine whether symptoms are caused by a breathing disorder, insomnia, abnormal movements, a circadian rhythm problem, or another medical or behavioral condition. The Stanford Sleep Clinic and affiliated Stanford Sleep Medicine Center provide evaluation and treatment resources for people experiencing a wide range of sleep concerns. The Stanford Sleep Clinic webpage provides clinical sleep resources outlining common disorders, diagnostic steps, and treatment options.
What a sleep clinic evaluates
A sleep consultation usually begins with a detailed review of symptoms, health history, medications, daily routines, and sleep habits. Clinicians may also use sleep questionnaires, a sleep diary, and a focused physical examination. Depending on the concern, care may involve specialists with backgrounds in sleep medicine, neurology, pulmonology, psychiatry, behavioral health, dentistry, or ear, nose, and throat surgery.
This coordinated approach is useful when symptoms overlap. For example, loud snoring and daytime fatigue may suggest sleep apnea, while difficulty falling asleep may be related to insomnia, anxiety, irregular schedules, medication effects, or another sleep disorder.
Sleep testing options
Objective testing is recommended when the clinical evaluation indicates that more information is needed. The appropriate test depends on symptoms, risk factors, and the suspected condition.
- In-laboratory polysomnography: An overnight study in the sleep lab records brain activity, breathing, oxygen levels, heart rate, body movements, and limb movements. It can help evaluate sleep apnea, periodic limb movement disorder, parasomnias, and other complex concerns.
- Home sleep testing: For some people, an at-home study may be an appropriate way to assess suspected obstructive sleep apnea, particularly when the clinical picture suggests a moderate or severe breathing disorder.
- Multiple sleep latency testing: This daytime test may be used after an overnight study when excessive sleepiness raises concern about narcolepsy or another hypersomnia disorder.
A sleep specialist determines whether testing is necessary and explains what the results can—and cannot—show. Home testing is not suitable for every patient, especially when symptoms are complicated or another sleep condition may be present.
Conditions commonly addressed
The Stanford sleep medicine program addresses problems that can interfere with nighttime rest and daytime functioning, including:
- Obstructive and central sleep apnea
- Chronic insomnia
- Excessive daytime sleepiness and hypersomnia
- Narcolepsy evaluation
- Restless legs syndrome and periodic limb movements
- Circadian rhythm sleep disorders
- Parasomnias and unusual nighttime behaviors
Treatment is selected according to the diagnosis, health history, preferences, and practical needs of each patient. Options may include positive airway pressure therapy, an oral appliance, behavioral treatment, medication, lifestyle changes, or surgical assessment when appropriate.
Treatment and follow-up
For many people with sleep apnea, continuous positive airway pressure therapy is an important treatment. Follow-up can address mask comfort, equipment use, treatment response, and difficulties maintaining regular use. Oral appliances may be considered for selected patients, and surgery may be discussed when an anatomical issue or other clinical factor makes it appropriate. The Stanford Sleep Clinic also explains narcolepsy risk factors and how they affect daytime alertness.
Chronic insomnia is often treated with cognitive behavioral therapy for insomnia, commonly called CBT-I. This structured, non-drug approach addresses sleep-related habits, routines, and thoughts that can perpetuate insomnia. Sleep education and behavioral strategies may also support treatment for circadian rhythm disorders and restless legs syndrome.
Care generally follows a sequence: an initial consultation, testing if needed, discussion of the results, treatment initiation, and follow-up. Follow-up visits provide an opportunity to assess progress and adjust the plan rather than relying on a single test or appointment.
Research and education
As an academic sleep center, Stanford also has a role in research, professional education, and patient education. Work associated with the sleep lab includes the study of sleep physiology, disrupted breathing, insomnia, hypersomnia, and potential new treatments. Some patients may be able to consider a clinical research study if they meet its eligibility requirements and are interested in participating.
Preparing for a visit or sleep study
Before an appointment, prepare a list of medications and describe when symptoms began, how often they occur, and how they affect daytime activities. Information about snoring, witnessed breathing pauses, morning headaches, nighttime movements, unusual behaviors, and daytime sleepiness can be helpful. Bring a sleep diary if you keep one.
For an overnight laboratory study, the sleep team will explain how to prepare and what to expect. Patients are commonly asked to follow instructions about caffeine, naps, and personal hygiene before arriving. Technicians explain the monitoring sensors and procedures, and the results are reviewed later with a clinician.
Referral requirements, insurance coverage, and scheduling procedures can vary. Checking with the clinic, primary care provider, and insurer before requesting an appointment may help clarify the next steps. For people with ongoing or disruptive sleep symptoms, a specialized evaluation can provide a clearer diagnosis and a structured path toward treatment.
