Symptoms of sleep apnea and diagnosing this condition

Symptoms of sleep apnea include:  snoring, gasping for air during sleep, waking up frequently, morning irritability, headaches and sleepiness. 
Sleep apnea can decrease a person’s memory and judgment; a tired person can experience accidents, including car crashes. 

Diagnosing sleep apnea is done after an overnight stay in a sleep lab.  The test is called a polysomnogram (PSG).  The person spends a night at the sleep lab, connected to monitors and cameras which document every move and breath the person takes.
