The majority (90%) of SIDS deaths occur before a child is 6 months old, with most happening between 1 month and 4 months of age. SIDS was the leading cause of death in children between 1 month and 1 year of age in 2013. (2018).Data from the Centers for Disease Control and Prevention (CDC) show that 1,545 infants died from sudden infant death syndrome (SIDS) in 2014 (the most recent year for which data are available).

Sudden unexpected death in epilepsy (SUDEP).

Five common causes of sudden unexpected death every EMS provider should know. You can learn more about how we ensure our content is accurate and current by reading our editorial policy.

Anyone at any age and in any state of health can have SDS. It’s important to note that despite these identified risk factors, they don’t mean you have SDS. Both can lead to an irregular or rapid heartbeat (arrhythmia). It can also interfere with the electrical system. This condition causes the heart’s walls to thicken.

It could lead to symptoms such as fainting or dizziness. The heart may beat too slow or too quickly. An arrhythmia is an irregular heart rate or rhythm. Most deaths occur immediately after a seizure. Each year, sudden unexpected death in epilepsy (SUDEP) occurs in about 1 out of every 1,000 people diagnosed with epilepsy. The first sign of the disease is cardiac arrest. Approximately 1 of every 2 deaths caused by coronary artery disease are sudden. Coronary artery disease is the most common underlying disease connected to SDS. Lithium is sometimes used to treat bipolar disorder. In addition to these risk factors, certain medical conditions can increase the risk of SDS, such as: Individuals from Japan and Southeast Asia have a higher risk for Brugada syndrome. Males are more likely to have SDS than females. Just 15 t o 30 percent of confirmed cases of Brugada syndrome have the gene that’s associated with that particular condition. Not everyone with SDS has one of these genes, though. If a person has SADS, for example, more than 20 percent of their first-degree relatives (siblings, parents, and children) are likely to have the syndrome, too. Researchers have found specific genes may increase a person’s risk for some types of SDS. However, there are some risk factors that increase a person’s likelihood of having some of the conditions associated with SDS. SDS often causes no visible signs or symptoms. People with SDS usually appear perfectly healthy before their first cardiac event or death. Let’s look more closely at the steps that can be taken to diagnose some of the conditions associated with SDS and possibly prevent cardiac arrest. You may be able to treat the underlying cause of possible SDS if you are. It’s sometimes possible to know if you’re at risk. Only 70 cases of it have been identified in the last two decades. Another SDS condition, long QT syndrome, may occur in 1 in 7,000 people. One particular condition, Brugada syndrome, may also cause sudden unexpected nocturnal death syndrome (SUNDS).īecause SDS is often misdiagnosed or not diagnosed at all, it’s unclear how many people have it.Įstimates suggest 5 in 10,000 people have Brugada syndrome. These syndromes may be one of the many conditions that fall under sudden infant death syndrome (SIDS). In people of this age, the unexplained death is known as sudden adult death syndrome (SADS). SDS is more common in young and middle-aged adults. Irregularities in electrical channels are more difficult to spot. Some estimates report at least 4 percent of people with SDS have no structural abnormalities, which would be the easiest to determine in an autopsy. But if a coroner takes steps to understand the precise cause, they may be able to detect signs of one of the syndromes of SDS. When a person with SDS dies, the death may be listed as natural cause or heart attack. Many cases of SDS aren’t properly diagnosed, either.

Most people don’t know they have the syndrome until a cardiac arrest occurs. All may cause unexpected and abrupt cardiac arrest, even in people who are otherwise healthy. Others may be the result of irregularities within the electrical channels. Some of these syndromes are the result of structural problems in the heart.
