Address: 101-24 Queens Blvd Suite A Forest Hills, NY 11375 Phone: 347-486-5329 Those with sleep apnea may snore loudly or even stop breathing for moments while they are asleep, which may cause the patient to wake up gasping for air. When the sleep apnea sufferer is awake, they may complain of morning headaches, memory loss, poor concentration and feeling exhausted throughout the day. This condition also puts patients at a higher risk of accidents and medical emergencies like a stroke or heart attack. If you have any of these symptoms then you may have sleep apnea. In order to properly diagnose your sleep apnea, you will need to come into our sleep clinic overnight for an evaluation. We will perform a sleep study, also known as a polysomnogram, which will record your physical activity while you sleep. If sleep apnea is suspected, then we will most likely perform this sleep study over two nights.
