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.
Apnea Hypopnea Index (AHI) The AHI is the number of apneas or hypopneas recorded during the study per hour of sleep. It is generally expressed as the number of events per hour. Based on the AHI, the severity of OSA is classified as follows: None/Minimal: AHI < 5 per hour. Mild: AHI â¥ 5, but < 15 per hour.
