Understanding Polysomnography Sleep Study
- A polysomnography sleep study is a comprehensive diagnostic tool used to assess sleep disorders.
- It involves overnight monitoring of brain activity, oxygen levels, heart rate, breathing, and body movements.
- This sleep study is especially valuable for identifying conditions such as sleep apnea, restless leg syndrome, and narcolepsy.
- As a result, it helps doctors create an accurate treatment plan tailored to individual sleep issues.
Why is Polysomnography Essential?
- Poor sleep not only affects energy levels but also contributes to serious health conditions like hypertension and heart disease.
- For example, undiagnosed sleep apnea may lead to chronic fatigue, mood swings, and impaired memory.
- Therefore, timely diagnosis through a sleep study can drastically improve sleep quality and overall health.
Types of Sleep Disorders Diagnosed by Polysomnography
- Obstructive Sleep Apnea (OSA)
- Central Sleep Apnea
- Periodic Limb Movement Disorder
- REM Sleep Behavior Disorder
- Insomnia with underlying neurological causes
- In addition, it can detect abnormal sleep cycles and sleepwalking behaviors.
What Happens During the Polysomnography Test?
- The test is performed overnight at a sleep center under medical supervision.
- You’ll be connected to sensors that track various bodily functions throughout the night.
- Although it may seem uncomfortable initially, most patients adjust quickly.
- Moreover, a technician is available to assist in case you feel uneasy during the test.
