Washington D.C., May 8: The prime time for brain development in a child's life is the first year, where the infant spends most of the time asleep. It is the time when neural connections form and sensory memories are encoded.
However, when sleep is disrupted, as occurs more often among children with autism, brain development may be affected, too.
New research led by the University of Washington finds that sleep problems in a baby's first 12 months may not only precede an autism diagnosis but also may be associated with altered growth trajectory in a key part of the brain, the hippocampus.
The study, which was published in the American Journal of Psychiatry, researchers report that in a sample of more than 400 taken of 6- to 12-month-old infants, those who were later diagnosed with autism were more likely to have had difficulty falling asleep.
It also states that this sleep difficulty was associated with altered growth trajectories in the hippocampus.
"The hippocampus is critical for learning and memory, and changes in the size of the hippocampus have been associated with poor sleep in adults and older children.
As many as 80 per cent of the children with autism spectrum disorder have sleep problems," said Annette Estes, director of the UW Autism Center and senior author of the study.
"In our clinical experience, parents have a lot of concerns about their children's sleep, and in our work on early autism intervention, we observed that sleep problems were holding children and families back," added Estes, who is also a UW professor of speech and hearing sciences.
"It could be that altered sleep is part-and-parcel of autism for some children. One clue is that behavioural interventions to improve sleep don't work for all children with autism, even when their parents are doing everything just right. This suggests that there may be a biological component to sleep problems for some children with autism," said Estes.
To consider links among sleep, brain development, and autism, researchers at the IBIS Network looked at MRI scans of 432 infants, surveyed parents about sleep patterns, and measured cognitive functioning using a standardized assessment.
At the outset of the study, infants were classified according to their risk for developing autism: Those who were at higher risk of developing autism -- about two-thirds of the study sample -- had an older sibling who had already been diagnosed.
Infant siblings of children with autism have a 20 per cent chance of developing autism spectrum disorder -- a much higher risk than children in the general population.
In the current study, 127 of the 432 infants were identified as "low risk" at the time the MRI scans were taken because they had no family history of autism.
They later evaluated all the participants at 24 months of age to determine whether they had developed autism. Of the roughly 300 children originally considered "high familial risk," 71 were diagnosed with autism spectrum disorder at that age.
Problems with sleep were more common among the infants later diagnosed with an autism spectrum disorder, as were larger hippocampi. No other subcortical brain structures were affected, including the amygdala, which is responsible for certain emotions and aspects of memory, or the thalamus, a signal transmitter from the spinal cord to the cerebral cortex.
The authors note that while parents reported more sleep difficulties among infants who developed autism compared to those who did not, the differences were very subtle and only observed when looking at group averages across hundreds of infants.
Sleep patterns in the first years of life change rapidly as infants transition from sleeping around the clock to a more adult-like sleep/wake cycle. Until further research is completed, Estes said, it is not possible to interpret challenges with sleep as an early sign of increased risk for autism.

Sandy. you really have sandy mind. PFI is not banned anywhere. you lie as you have no ground to blame PFI and no right to blame. As RSS links to terror already revealed by national media and NIA . just ask your RSS to shift to Pakistan or nepal, As they dont even hoist national flag
i dont think this ibrahim is ibrahim, i think he is not a muslim and uses false name and internet knowledge to give stupid comments and force us to reply to him..
why are you saying baseless things, Its not banned anywhere. Don’t just say the things which come into your mind without understanding them properly. Your message is foolish, ignorant and a comment without any responsibilities
@ sheikh ibrahim,
well said sir, I am sure your qualified and understand the Quran very well.
But atleast they are doing there part -what you are doing. If you have mashallah this concern then work for the cause - teach them quran and do something about it insted of just complaining.
Now please don’t give excuse that you cant ?
Because you haven’t tried.
in 1 hour a week , will also make a difference,
If you can’t then please try and hire an imam for 1 hour a week.
If you can’t even do that then donate 100 rupees a week to help that cause and help them learn Quran.
If 100 rs is to much then try 10 rs. if every one will do something insted of complaining the world will definately be better place.
Insha’Allah
Do you have any proof for your blabbering, or its just coming out forged by your hatred for the community?
As per Israel – it is believed to be anti-Islamic by many, some people support Israel just for its alleged agenda.
But to your allegation of SDPI backing “jihad against kafirs” if your definition of jihad is just like ISIS/RSS -then you are legally obliged to provide proof for your allegation and put the culprits behind bar, serving our great nation. If not then this is just a defamation.
@yogesh , so you haven’t heard about saffron terrorist?
all RSS people are where and will remain Hindus!!. Further many people wear the mask of Muslims but very few are Muslims. Also the leaders name of IS is said to be Simon Elliot. In military standard false flag operation were common by Israeli before , This is just an advance tactic, A
lso if what SDPI is saying in this particular matter is right shouldn’t you say it to be right. D
isagree with them or any one where they are wrong, But not when they are right.
@ unknown( coward/hypocrate) using false identity.
By your logic
I don’t believe this but its just to answer the retard who drew the conclusion
Nathuttam godse = killer of the father of our great nation
Hence, godse = enemy of India
godse = hindu
Hence proved
Hindu = enemy of India ?
Further,
All religion / country have there black sheeps and terrorist.
If you are sensible you can not generalise or sterocast people.
haha biggest joke , 400++ isis sympathisers are having PFI background :) double game dont work . In one side telling isis is israel and anti islam and in other side openly backing jihad against kafirs .
Please watch an interview which was done in 1990 youtube "
ISIS=Israeli Secret Intelligence Service"
In an excerpt from a 1990 C-SPAN interview with Brian Lamb, Dan Raviv and Yossi Melman, authors of the book Every Spy a Prince: The Complete History of Israel’s Intelligence Community, describe how the Israeli Prime Minister’s Office officially refers to its subordinate organization “the Mossad”
HEY cANDY, Tell me which state banned PFI?
Comman can understand it is a propaganda against org. Why PFI should ban for it's uncompromising stand against Fascism? Against Rss terror activities in India?Moth piece of RSs media failed to present a Proper evidence against PFI why?
Many states banned PFI because of their link with terrorists
Rubbish. Total rubbish. Ban PFI
Many of the PFI workers dont know the real meaning of Islam and they didn't read Quran fully or properly
PFI said the truth but these people dont have any right to blame them. Because these people only number one trouble makers.
ISIS=Muslims
PFI+SDPI=Muslims
Hence ISIS=PFI+SDPI ie Muslims
But all IS terrorists are/were Muslims only.
