Sleep Disorders (PDQ®)

Assessment of Sleep Disorders

An assessment is done for patients with sleep disorders.

An assessment is done to find problems that may be causing the sleep disorder and how it affects your life. Patients with mild sleep disorders may be irritable and unable to concentrate. Patients with moderate sleep disorders can be depressed and anxious. These sleep disorders may make it hard for you to stay alert and involved in activities during the day. You may not be able to remember treatment instructions and may have trouble making decisions. Being well-rested can improve energy and help you cope better with side effects of cancer and treatment.

Cancer patients should have assessments done from time to time because sleep disorders may become more or less severe over time.

A sleep disorder assessment includes a physical exam, health history, and sleep history.

Your doctor will do a physical exam and take a medical history that includes:

You and your family can tell your doctor about your sleep history and patterns of sleep.

A polysomnogram may be used to help diagnose the sleep disorder.

A polysomnogram is a group of recordings taken during sleep that show:

  • Brain wave changes.
  • Eye movements.
  • Breathing rate.
  • Blood pressure.
  • Heart rate and electrical activity of the heart and other muscles.

This information helps the doctor find the cause of your sleeping problems.
