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.
AHI (Apnea Hypopnea Index) is the number of apneas and hypopneas per hour. Or an index for sleep apnea. 5-20 mild, 21-50 moderate, above 50 severe. The Greek word âapneaâ means âwithout breath.â You stop breathing during sleep for ten seconds or longer. During a Hypopnea there is airflow through your throat but at a much reduced level, which leads to not getting enough oxygen.
