Using SPECT imaging, weâve discovered that depression and anxiety, like many other psychiatric conditions, are not just single or simple disorders, but rather there are 7 different types based on different patterns in the brain, and each requires its own treatment.
Apnea: Introduction. Apnea is a cessation or pause in breathing. Very short episodes of apnea can be normal, and a person can induce voluntary, short-term apnea by holding one's breath. However, apnea can also be a symptom of a variety of mild to serious disorders, diseases or conditions.
Sleep apnea occurs when you regularly stop breathing for 10 seconds or longer during sleep. It can be mild, moderate, or severe, based on the number of times an hour that you stop breathing (apnea) or that airflow to your lungs is reduced (hypopnea). This is called the apnea-hypopnea index (AHI). 1  Mild apnea. 2  Mild apnea is defined as 5 to 14 episodes of apnea or reduced airflow to the lungs every hour.
