A medical condition that makes some people falsely believe that they are real vampires
Sleep apnea occurs when an adult regularly stops breathing or has slowed breathing during sleep for 10 seconds or longer. It can be mild, moderate, or severe, based on the number of times per hour breathing stops (apnea) or slows (hypopnea).
The three main types of sleep apnea are:
Obstructive sleep apnea (OSA), which is the result of blocked airflow during sleep, such as from narrowed airways. Other factors, such as obesity, often contribute to obstructive sleep apnea.
Central sleep apnea, which results from a problem with how the brain signals the breathing muscles. This type of apnea can occur with conditions such as heart failure, brain tumors, brain infections, and stroke.
Mixed sleep apnea, which is a combination of obstructive and central sleep apnea.
A person who has sleep apnea may snore loudly and have restless sleep with difficulty breathing. The person may wake up with a headache and be very tired throughout the day.
Sleep apnea may improve with changes in sleep habits, such as not sleeping on your back. Sometimes devices to help breathing during sleep are useful, and occasionally surgery may help.
The main symptom of chronic fatigue syndrome (CFS) is a devastating tiredness or exhaustion that has lasted at least 6 months and does not improve much with rest. This fatigue also is so severe that it interferes with your work, your play, and your social activities. The fatigue and other symptoms described below may begin suddenly or they may develop gradually over weeks or months. Read more...
Catalepsy
Catalepsy is a disorder of the nervous system that causes a form of suspended animation. It causes a loss of voluntary motion, a rigidity to the muscles, as well as decreased sensitivity to pain and heat. A person suffering from catalepsy can see and hear cannot move. Their breathing, pulse, and other regulatory functions are slowed to the extent that to an untrained eye, it would seem as though they were deceased.
