-These breathing pauses accompanied by snoring.

- occurs in all age groups and both sexes but is more common in men. Sleep apnea runs in families, suggesting a possible genetic basis
- Symptoms: depression, irritability, sexual dysfunction, learning and memory difficulties, and falling asleep. Risk for heart attack and stroke may also increase in those with sleep apnea
-Medications are generally not effective in the treatment of sleep apnea. Oxygen is sometimes used in patients with central apnea caused by heart...
