Basic Facts

  • Insomnia is a sleep disorder that can make it hard to fall asleep and/or remain asleep.
  • Insomnia can be short-term because of stress or a traumatic event.
  • Some people have long-term (chronic) insomnia that lasts for months or years. 
  • Chronic insomnia can significantly impair a patient’s quality of life and is associated with a higher risk of developing diseases. 
  • Most adults need 7-8 hours of sleep at night, although sleep needs can vary from person to person.
What is involved in a sleep study?

While difficulty falling asleep and/or staying asleep is the primary symptom of insomnia, other symptoms include: 

  • Daytime sleepiness
  • Irritability, depression or anxiety
  • Poor concentration and focus
  • Lack of coordination, leading to an increase in error or accidents (driver sleepiness is a major factor in non-alcohol related car crashes)
  • Tension headaches

Insomnia itself may be a symptom of an underlying medical condition.

Insomnia is most common in shift workers, the elderly, and menopausal women.

Many medical conditions, such as chronic pain, reflux or Parkinson’s disease can lead to insomnia. Also, certain medications, especially those with stimulant properties. 

Sleep apnea- blocked airway causes a person to repeatedly stop breathing.

Restless legs syndrome- feeling an uncomfortable sensation to move one's legs.

In addition to taking a detailed medical history, listening to the patient describe symptoms, and conducting a physical exam, the healthcare provider may also recommend:

  • Polysomnogram (PSG) – This is a nighttime study monitors sleep stages and cycles to identify when sleep patterns may be disrupted. The study records a variety of bodily functions during sleep such as the electrical activity of the brain, blood oxygen levels, heart rate, and breathing, as well as eye and leg movements. 
  • Multiple Sleep Latency Test (MSLT) -- MSLT is a daytime study, which involves a series of naps, to assess sleepiness during the day. The equipment used in an MSLT study is less extensive than a nighttime study.

 

Cognitive behavioral therapy, focuses on developing habits that promote a healthy pattern of sleep, is often a first line of treatment for insomnia.

  • Relaxation training – These techniques, which help to calm the body and induce sleep, may include breathing exercises, mindfulness skills, meditation practices, and guided imagery. 
  • Sleep hygiene – Limiting activities around bedtime and in the bedroom, allowing your brain to "turn off" and get to sleep. This includes limiting the use of caffeine, tobacco, and alcohol as well as increasing exercise during the day. 

Medications including over-the-counter sleep aids, prescription sleeping pills, antidepressants, and melatonin. Determining which medication may be best depends on insomnia symptoms and many different health factors; it’s important to consult with a healthcare provider about the use of sleep aids.
