Sleep apnea

Alternative Names

Symptoms

It is important to emphasize that often, the person who has obstructive sleep apnea does not remember the episodes of apnea during the night. The predominant symptoms are usually associated with excessive daytime sleepiness due to poor sleep during the night. Often, family members, especially spouses, witness the periods of apnea. Symptoms that may be observed include:

• Loud snoring
• Periods of not breathing (apnea)
• Awakening not rested in the morning
• Abnormal daytime sleepiness, including falling asleep at inappropriate times
• Morning headaches
• Recent weight gain
• Limited attention
• Memory loss
• Poor judgment
• Personality changes
• Lethargy

• Hyperactive behavior, especially in children
• High blood pressure
• Automatic behavior (performing actions by rote)
• Leg swelling (if severe)

Exams and Tests

A complete medical history taken by a health care practitioner is the most important diagnostic tool. Often, a survey that asks a series of questions about daytime sleepiness, sleep quality, and bedtime habits is given.

A physical examination of the mouth, neck, and throat will be done. Other tests may include:

• Arterial blood gases
• ECG
• Echocardiogram
• Sleep studies
• Thyroid function studies
