Diagnosis & Complications

To diagnose hypersomnia, a health expert will check your medical history and symptoms. They also conduct a physical exam to test for alertness. Several tests and treatment methods your doctor might suggest are:

  • Sleep diary- It helps you record your waking and sleeping time through the night to understand sleeping patterns.
  • Multiple sleep latency test- You need to take a nap in the lab for this test which will measure your sleep experience.
  • Epworth Sleepiness Scale- You need to rate your sleepiness to determine the seriousness of the condition.
  • Polysomnogram- You need to stay at a sleep centre. A machine monitors eye movement, brain activity, oxygen levels, breathing function, and heart rate.

Hypersomnia can cause vehicle accidents, as you can fall asleep while driving. You may also feel tired all the time. It might even trigger anxiety and depression. If you notice any signs of hypersomnia, you must see a doctor to control the condition before it worsens.

Treatment & Prevention

If you are diagnosed with hypersomnia, your health expert will prescribe several drugs, such as antidepressants, stimulants, and new medications like Xyrem and Wakix. They can also advise you on a treatment called continuous positive airway pressure or CPAP.

In this treatment, you cover your nose with a mask during sleep. The mask will be attached to a machine providing continuous airflow into your nostrils. This will help you open your airways. If you take any medications, discuss them with your doctor. When you are under treatment, you will need to go to sleep earlier to get more sleep at night and eliminate caffeine and alcohol.

If you have not developed this condition yet, you can prevent it by improving your sleep pattern. Get in bed at the same time every day, create a cool and comfortable sleep environment, avoid working late at night, change medications that cause drowsiness, and avoid drinking a few hours before sleeping time. These things can help you reduce the risk of hypersomnia if you do not have an underlying health condition.
