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.

Kotiaan brothers did not see the carrot saffron shakes video of aseemanada and Nithyananda rapes....ha ha...he loves Arab porn...like all sangheez even watch in Parliament....
Piece loving nation ..haha. ..I also saw the video where Arab milk shakes raping indian women maids from Hyderabad ..
Dear Satya Vishwas...
U are right but what We muslims need to Present the TRUE message of ISLAM to the public as well as the cheddis .. cos they are carrying in their mind the ISLAM which is taught by the Cheddis.. which is dumping them deep into darkness (hate, jealousy, crime, looting, lies and etc) as well as the society.
So we should educate whatever way to spread the real msg of ISLAM to the cheddis as well as the non muslims ...
When we present the true message atleast few may reflect who are honest.. in their hearts. ALLAH guides those who are honest in looking for God.
Why CD readers bother about this Phycho person;(Phycho Viren) this man must be admitted Kankanady hospital for his brain wash in Vande dot CLOREX muthram.
dear all CD readers : please do not react , or comment to viren kotian just neglect him,BECAUSE HE IS DEPLOYED by RSS to ignite and provoke minorities, so if we react to his inhumane comments he and his dirty mind followers enjoy it.And they are successful in their mission, and also he get highlighted , so why to give him unnecessary (un) popularity.
REMEMBER THAT IF YOU THROW A STONE AT LOOSE SHIT (VIREN) IT SPREADS ALL OVER .
so lets not waste our valuable time by arguing with the inhuman viren.
Viren Kotian , seeing your comments i understand that a deluded understanding is giving such a buncombe, please understand such swaggering appears unarmed for a rational discussion.
kindly refrain
Vande matram means cheddis bow down to the mother land...
What islam says
ALLAH is the lord of all that exists, U me and all that is in between the earth and the skies..
We Muslims bow down to ALLAH alone and nothing else , Even not to our respected prophets or our mother who gave birth to us...
We love our prophets,
We love our mother
We love our mother land
but we will never worship our mother land...
ALLAH created us and We bow down to him alone.. Please dont ask me to bow down to the motherland which is also a creation of ALLAH...
ALLAH forgives every sin with true repentance but associating partners with him is the biggest SIN... which is a way to hell and Please dont drag us Muslims to that destination... Sorry I believe ALLAH as my lord, Muhammad pbuh and all the prophets as my messenger and Islam as my religion....
Please VIREN when U worship the mother land, U actually denying the TRUE GOD ... I request U to look who is our CREATOR which VEDAS also mentions \NA TASYA PRATIMA ASTI\" there is no image of GOD...
IF you are honest in looking for the CREATOR , God will Guide U ... Atleast make some effort to look for the creator of all that exists.. Dont just worship the man made creations and animals and live a life unaware.. QURAN challenges mankind to bring a book like it... Please go thru it."
No one can become patriot just saying vande matram, this is crazy....we Muslims cannot do that...its against our religion...but in fact we will fight for our country without any hesitation.....and save country from our enemies.....
Hello joker Viren......a lot of bharat maa ki jai sons are also living happily with their family's in Muslim countries and they respect and are thankful to those people. Some goons like you will let Islamic nations kick them out of there.......you sick-minded will let people hate each other...saffron pillas....why don't modi offer job and respect to the people who say jai jai and are still working in Islamic nations.......u don't belong to a democratic nation.......go to your country Nepal....ha haa
Viren Kotian, how could you say, the person who doesn't sing Vande Mataram is not be Indian!!!
You must know its not our National Anthem and its an individual personal choice.
I don't understand why CD post such nonsense Viren Kotian comments!!
Viren, I think you don't have any knowledge of our Indian constitution!!
Bharat Mata har ek Hindustani ki hai, aur Akbar ek hindustani hai, apne desh se madad maang raha hai, samajh is baat ko. and
don't ever bring communal things in humanity!!!
Mr. Kotian why so much hatred on muslim relegion, we are human beings, remember that.. we are indians here we don't treat each other as HINDU's or MUSLIM's.. Try to be peace lover My Dear Friend..
Bharath kisi ke baap ka nahi. The slogan made purely illogic for any religion including hindus which is against the holy scriptures. Will you and your millions of hindu brothers say La ilaha illallah mohammedurrasulullah while entering in arab countries to earn their bread and butter.
Dear viper kotian if u sing vande maataram r u getting 15 lac from your govt? Then why u r singing r u mad?
Viren kotian.
Its haraam to say vande mataram according to vedas. Hindu is not a religion. Arabs gave the word hindu. U should be thankful to arabs.
Rama couldnt save his own wife sita from kidnap. How can he save u.
Ask any pandit. He will runaway from u.
The religion is sanatan dharm. Nowadays nobody knows a single word of it.
Habeebi viren, dont worry we will try to help him out.. If you are not sleeping then try to see the problems of those who sing vande mataram and still not came out of it. I doubt the govt helps them.
Indian govt should help this guy.
Viren - stop talking nonsense ( as usual )
What is Indian embassy doing around.....they got a lot money of expatriates collected during passport renewal time....millions of them...couldn't they use part of it to get this person come out of his ordeal...
You are not ready to sing 'vande mataram' but when you get stranded in a Muslim country you need bharat maatha's hindu govt's help. Funny people.
