Conditions a Sleep Study Can Diagnose

 

An overnight sleep study helps physicians diagnose a wide range of sleep disorders and neurological sleep conditions, including:

• Obstructive Sleep Apnea (OSA)

• Central Sleep Apnea

• Snoring and Upper Airway Resistance Syndrome (UARS)

• Insomnia (when additional evaluation is needed)

• Restless Legs Syndrome (RLS)

• Periodic Limb Movement Disorder (PLMD)

• Narcolepsy (with additional daytime testing)

• REM Sleep Behavior Disorder

• Parasomnias such as sleepwalking or night terrors

• Certain nighttime seizure disorders

 

By accurately identifying the cause of your symptoms, your physician can develop a treatment plan that is personalized to your specific diagnosis rather than simply treating the symptoms.

​

Signs You May Need a Sleep Study

 

Your healthcare provider may recommend a sleep study if you experience symptoms such as:

• Loud or chronic snoring

• Pauses in breathing during sleep

• Gasping or choking awake

• Excessive daytime sleepiness

• Morning headaches

• Difficulty concentrating or memory problems

• Frequent nighttime awakenings

• Restless sleep

• Unexplained fatigue

• High blood pressure that is difficult to control

• Suspected nighttime seizures or unusual movements during sleep

 

Even if your symptoms seem mild, untreated sleep disorders can affect your cardiovascular health, mood, metabolism, memory, and overall quality of life. Early diagnosis allows treatment to begin before complications become more serious.

What Happens During an Overnight Sleep Study?

 

Many patients worry they won't be able to sleep during the test. This is completely normal—and fortunately, most people sleep enough for the study to gather the information needed.

​

When you arrive at the sleep center, one of our experienced sleep technologists will explain the process and answer any questions you have. Small sensors are gently placed on your scalp, face, chest, legs, and fingers using medical-grade adhesive. These sensors are painless and simply record information while you sleep—they do not deliver electricity or cause discomfort.

 

Throughout the night, the study monitors:

• Brain wave activity (EEG)

• Eye movements

• Heart rhythm (ECG)

• Breathing patterns

• Airflow

• Blood oxygen levels

• Leg movements

• Muscle activity

• Body position

• Snoring

 

A trained sleep technologist monitors the study throughout the night to ensure high-quality recordings while helping you remain as comfortable as possible.

​

The Difference Between an In-Lab Sleep Study and a Home Sleep Test

 

Depending on your symptoms, your physician may recommend either an in-lab sleep study or a home sleep apnea test. Home Sleep Apnea Testing is typically used when obstructive sleep apnea is strongly suspected in otherwise healthy adults. It focuses primarily on breathing, oxygen levels, airflow, and respiratory effort.

​

In-Lab Polysomnography provides much more comprehensive monitoring and may be recommended if your provider suspects:

• Complex sleep apnea

• Narcolepsy

• Parasomnias

• REM behavior disorder

• Periodic limb movement disorder

• Neurological sleep disorders

• Nighttime seizures

• Multiple or unclear sleep-related symptoms

 

Your physician will recommend the study that best fits your symptoms and medical history to ensure the most accurate diagnosis.

​

Why Early Diagnosis Is Important

 

Poor sleep affects far more than just your energy level. Untreated sleep disorders have been linked to an increased risk of:

• High blood pressure

• Heart disease

• Stroke

• Type 2 diabetes

• Depression and anxiety

• Memory difficulties

• Workplace accidents

• Motor vehicle accidents

• Reduced immune function

 

Many patients are surprised to discover how dramatically their quality of life improves once an underlying sleep disorder is identified and treated. Better sleep often means better health, sharper thinking, improved mood, and more energy for everyday life.
