Diagnosis of insomnia

A primary care doctor can diagnose insomnia but may send you to a sleep specialist for further testing and treatment in severe cases.

Your doctor will take a full medical history, ask questions to determine your sleep history and perform physical exam during your clinic visit. He or she may recommend filling out a sleep log to help you tract your sleep patterns.

Other tests he or she may order include:

  • Sleep study — during an overnight sleep study, you will be connected to an EEG, which monitors the stages of your sleep, your oxygen levels and heart rates.
  • Blood test — can rule out other conditions that may be causing your symptoms.

Treatment for insomnia

Your doctor may recommend lifestyle and home remedies, like improved sleep habits, as well as encourage you to address concerns that may be causing your sleep issues such as stress, eating habits or work hours, before moving to more advanced treatment options.

If these changes are not allowing you to sleep soundly, your doctor may recommend the following treatments:

  • Cognitive behavioral therapy — can help you control negative emotions that disrupt your sleep.
  • Medications — prescription medications such as Lunesta, Rozerem, Sonata and Ambien can help you get to sleep and stay asleep longer. Medications should only be used for a few weeks at a time.
  • Alternative medicine — alternative medications such as melatonin, valerian, acupuncture, medication or yoga have also been proven effective in some patients to help them sleep better.
