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.

Temple are filled with IDOLs, All idols doesnt speak, it cannot help itself, it cannot move,,,, & ALLAH say human are intelligent when they THINK. I wonder Y intelligent beings are not thinking ???????
VEDAS says NA Tasya Pratima Asti... There is no image, statues and pictures of God.. Why are u worshiping such thing which is life less.
WORSHIP THE CREATOR NOT HIS CREATION... (Quran speaks lot about our LIFE and the creation of all that exists..) If the creator says Mankind is intelligent .. Then FIND out Who is worthy of Worship rather than blindly following and worshiping the LIFELESS objects..
SEEK guidance from the one who gave us soul, Just say OH God, the one who gave me soul - GUIDE me to the TRUTH..
U will be on the path of those who are successful... GOOD LUCK May ALLAH guide those who look for HIM.
I say you give all your other temples to Muslims and keep that 3 temple.
BJP always keeps this Rama mandir issue open to contest in election, if they build Rama mandir issue is closed, then there will not be a big issue to contest in election. One thing is clear BJP wont build Rama mandir. They are following divide & rule.
BJP is counting downfall because of such morons in their party
And about this giving and keeping business....does he thinks that it's as easy as giving his daughter to a Muslim boy
Guys,
Why Swami is handling the Muslim community because his only one daughter ran away with Muslim guy that is why he is in pain so everywhere he is carrying that pain that he was not able to control his daughter. we should understand his pain. just ignore him.
Subramanya swine has nothing to do as his name is fading away from active politics, this is just a publicity gimmick.
He went on top list of jokers in BJP for this joke...see the pic, he himself is not controlling on his own joke..
He is a big joker, see how he is laughing on his own joke...
Swami dreaming in day time, Contraction of temple I am sure not in your this life. you should take a rebirth again.
To dear Fair Hindu Brothers,
Please have control on his tongue. Truly, he does not represent Hindu Community.
As in every community, there are black sheep. He could be one of them,
However once again, his comments has no bearing with Fair Hindus. The strange, why BJP does not want to stop such crazy leaders to be in their core committee.
Therefore even BJP is also not yet all representing real HIndus.
Now in India, we need a very strong party in the national level., like AAP in Delhi., consisting of like minded fair and open people. Let us encourage AAP in the next election.
In Delhi, they are success, God willing they can be successful in Centre.
A New deception to FOOL people & Unthinking saffron plan to loot. More deception will come when Elections are nearer & nearer...
Looting the country & destroying the peaceful society is the only agenda of Such LOOTERS...
Forget about 3 mosques, we will not give you a dust from them...
one of sardar's of stupid .... joker swamy :p
Susu Swami network begins for the year 2016..
Ye tho pagal swami hai. !
Why only such jokers are leaders in BJP.
BJP Credibility and fate of commons : Yatha raja - Ta tha praja.
It is better if this stupid concentrates himself on fixing unemployment problems around...temple construction is not an issue for people...
forget about 3 temples............even you can not get 3 hairs instead.............. if the Ram janmabhoomi issue is resolved , then saffronists have no issue to revolt innocents against Us
Swami very understanding Gentleman as well he assume Millions of Millions Hindustani's are big buffoons what he thinks so, probably he do not understand why Temples, Mosques, Churches or any other spiritual places, swami for you better stay in spiritual place as a puja that is best job for you or better to go Tamilnadu and join Cheala work very good or we have to have some different options to you Gentle man.
Jai Hindustan
