Sudden infant death syndrome (SIDS) – causes, symptoms, diagnosis, treatment, pathology

Sudden infant death syndrome, or SIDS, which
is also known as cot death, crib death, is the sudden and unexplainable death of an infant
during their first year of life. Because of the seemingly random nature of
the condition, there are a number of risk factors that seem to correlate with getting
SIDS, but there’s no clear mechanism or cause that’s been identified. SIDS is considered a diagnosis of exclusion,
meaning all other causes have to be ruled out before an infant death is given that label. The most well-known risk factors have to do
with how an infant sleeps; to lower the risk of SIDS the recommendation is to make sure
that babies sleep alone in a crib, on their backs and without blankets. The risk of SIDS is higher among boys rather
than girls, as well as infants between two and four months old, and among formula-fed
babies, and those born prematurely or with low birth weight. Risk factors that relate to a mother include
receiving little or no prenatal care, being a teenage mother, and smoking during the pregnancy. Alcohol consumption is also thought to be
a risk factor because there are more cases of SIDS during weekends, the New Year, and
other times of year when drinking is included in celebrations. The fact that far more boys die of SIDS than
girls shows that there is a level of genetic susceptibility at play, but the exact specifics
are unclear. A minority of SIDS-related deaths show a correlation
with genetically inherited channelopathies, which are defects in ion channels that affect
a variety of tissues, including the heart. Another possible genetic link is the higher
incidence of SIDS in babies with gene mutations involved in the autonomic nervous system. These clues, though, are still being researched,
and no exact gene or combination of genetic defects has been identified. SIDS is generally thought to occur in children
that have a genetic susceptibility which is then triggered by external factors. An epidemiologic clue is that Native American
infants have the highest rates of SIDS while Asian infants have the lowest rates of SIDS. Cultural practices around sleep, though, might
also play a role, and so it makes it hard to tease apart genetic and environmental factors
when it comes to race. A diagnosis of SIDS can only be made following
an autopsy, to make sure that there isn’t an alternative explanation for an infant’s
death. For prevention, unfortunately because the
underlying cause of SIDS is unknown, there’s no surefire way to prevent it. All right, as a quick recap – sudden infant
death syndrome, or SIDS is a diagnosis of exclusion given to an infant that dies of
unknown causes, and is most common in infant boys between 2 and 4 months of age, but can
happen anytime in the first year of life. To minimize the risk of SIDS, infants should
be put to sleep on their back, should not be exposed to cigarette smoke, and should
be breastfed if possible.


  1. sir..please make video on r looking same..i cant able to differentiate b/w them.

  2. u have a very good voice which when emphasizes on things helps remmbr whats imp whats not….
    keep up ur work. i love ur videos….

  3. I've heard physicians with suspicions that many if not most cases of SIDS are truthfully infanticide. The risk factors and increases during times of alcohol consumption seem to indicate that is a possibility. What is your take on that theory?

  4. Always wondered if this is a survival mechanism. If an infant's body feels it is unable to survive in these conditions than it would shut itself down prematurely.

    That or maybe its linked to the causes of stroke since both seem so similar (heart & brain communicating to prematurely shut down).

  5. dear #Osmosis#… u r d master in selecting the most useful & entertaining points while preparing a script.. superb..!

  6. I actually really wanna know why people get attached to certain patterns of soundwaves (music).

  7. Always wonder what the guys who dislike theses videos really want! cmon! Its awesome stuff. (Maybe they press it by mistake)

  8. this reminds me, it's been like decades since Finland (I think) has done those government provided baby boxes and just recently America is just starting to see the benefits…

  9. Thanks guys for your great contributions. I have been following your video uploads on a regular basis. Keep up the great work.

  10. Risk factors –baby lungs are still developing and could stop breathing make sure you have good ventilation in the baby room to assist there breathing and the most important avoid placing the baby in the area of the room that the air are stale. Imagine a room with close windows and the house is air tight especially in North America is like a car with close windows no adequate fresh oxygen supply. If you have a furnace fan keep it on at all time to have air movement or have a electric fan. Hope this save life. thank you

  11. Baby girl – 8 lbs 1 1/2 ounces – 20 1/2 inches long. Just had six week checkup. The pediatrician called her perfect. Died 9 days later sleeping on her back. We all live on God’s time.

  12. Hello! I had a 5 month old grandchild that died from SIDS and I can tell you it is the most devastating event that will happen in your life! I Had a brief visit to heaven during my brain surgery and spoke to angels there and here about why god had chose to take my grandchild and they gave me answers about all of this. I wrote a book and its for sale now on amazon. (TO HEAVEN AND BACK WITH ANGELS). Its a great story and my intentions on writing the book is to comfort anyone who has had an infant death in their family. See a short preview of this story on youtube. Everyone must read this story!! Please buy, read and share!!! I really hope this helps someone thats wondering about their infants that went to heaven. Thank You!! Timothy Peak (Author).
