A genealogy was then created which included all the relatives and their vital status and/or circumstances of death. Society and culture
During the 1970s and 1980s, when an outbreak of this syndrome began, many Southeast Asians were not able to worship properly due to the Laotian Civil War. Hmong people believe that when they do not worship properly, do not perform religious rituals properly or forget to sacrifice, the ancestor spirits or the village spirits do not protect them, thus allowing evil spirit to reach them. These attacks induce a nightmare that leads to sleep paralysis, in which the victim is conscious and experiencing pressure on the chest. It is also common to have a REM state that is out of sequence, where there is a mix of brain states that are normally held separate. After the war, the United States government scattered the Hmong refugees across the U.S. in 53 different cities. Once these nightmare visitations began, a shaman was recommended for psychic protection from the spirits of their sleep. However, scattered across 53 different cities, these victims had no access to a shaman who could protect them. Hmong people believed that rejecting the role of becoming a shaman, they are taken into the spirit world.The study author suggested that the Hmong who died were killed by their own beliefs in the spiritual world, otherwise known as Nocturnal pressing spirit attacks. In Indonesia it is called digeuton, which translates to "pressed on" in English.
Sudden arrhythmic death syndrome (SADS) is a sudden unexpected death of adolescents and adults, mainly during sleep. One relatively common type is known as Brugada syndrome.The syndrome is rare in most areas around the world but occurs in populations that are culturally and genetically distinct. It was first noted in 1977 among southeast Asian Hmong refugees in the United States and Canada. The syndrome was again noted in Singapore when a retrospective survey of records showed that 230 otherwise healthy Thai foreign workers living in Singapore died suddenly of unexplained causes between 1982 and 1990. Causes
A sudden death in a young person can be caused by heart disease (including cardiomyopathy, congenital heart disease, myocarditis, genetic connective tissue disorders) or conduction disease (WPW syndrome, etc. ), medication-related causes or other causes. Rare diseases called ion channelopathies may play a role such as long QT syndrome (LQTS), Brugada syndrome (BrS), CPVT (catecholaminergic polymorphic ventricular tachycardia), PCCD (progressive cardiac conduction defect), early repolarization syndrome, mixed sodium channel disease, and short QT syndrome. In 20% of cases, no cause of death can be found, even after extensive examination.In young people with type 1 diabetes, unexplained deaths could be attributed to night time hypoglycemia triggering abnormal heart rhythms or cardiac autonomic neuropathy, a damage to nerves that control the function of the heart.Medical examiners have taken into account various factors, such as nutrition, toxicology, heart disease, metabolism, and genetics.
