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.

ISLAM is peace religion, never said do not feed non muslims and anti social activities... Always says respect them and their priest
Islam says see the neighbor's hunger and feed them.
DO GOOD WORK FOR SOCIETY and MAKE FAIL TO ALL HATE MONGERS.
Who the hell all these muslim hate mongers tom dicky harry to shed crocodile tears when muslim women muslim community have no objection with the issue. I doubt the husbands of those sharing dias have single relationship. They might have one by legal. But God knows howmany have made back door exit entry . We all knew how the aids spread and who are responsible for it. Haati ke daant khaane ke aur dikhane ke aur. This is bitter truth. Let them look into the referendum in their own community instead tarnish the image of islam and muslim community. They have raise the issues like casteism, untouchability , abortion, devadasi system, alcohol, prostituion, dance bars, fast track hearings for murders and rapists.
Alhamdulillah muslims are proud to be muslim. Islam is the way of life evidencing people embaracing it across the world after practicing different religion majority among are women. Subahanallah. This shows how the hate mongers are hatching the conspiracy against the peace religion. Inspite the efforts Islam will stan firm . More they try malign larger will benefit islam. Tareeq gawah hai.
Dear Ms. Bhat,
In Islam polygamy only allowed to those person who has the capacity to look after with justice. Of course, women are not a use & throw item. Do not under estimate polygamy. It can solve lot of social problems. If you think that marry more than one is just for satisfaction purpose, then do you have any answer about Lord Krishna, who has married 16,000 women?
Look at the frustration ..muah...chummah gang completely in disarray ...hahaha...jashoda Ben fans Anthe .. This community took women as property and they were raping women under the strict rules...this is the main reason 60% prostitutes in kamati puram are from -----community. Ree faizhal Bhai elree idira ....burqa togondra. . I mean for protest rally ge.....rikacha nu seriskondu bidi ....swalpa straight and balukuva made irli ...yaake Andre burqa haaki kondirodu gandu antha gottagbaardu ...haha ...chennagi practice maadri ...

Abu Muhammad #6 CALM DOWN...
People are Ignorant of the REALiTY without making their research they come out and make bow bow by BLINDLY following their Evil Stupid thinking Leaders who also trap the IGNORANTS who want to live a life of UnAware of the consequences with the CREATOR...
Ms. Bhat, I advise you to marry first, change your status from single to marital, try to become a mother to someone and enhance your family tree. with regards to your queries or objection whatsoever, I strongly recommend you to read Chapter Talaq in holy Quran just once in your life time, do a qualitative study, then come to the public (I'm sure then you don't need to come) give your statement.
Sulochana Bhat, first look into your house - in your Brahmin community when husband dies, the widow is shaven, locked in the house and called MUNDE BIRANDI. Women in her period is kept out of the house like dirty dogs, you like your sister to be prostitutes than being a second wife enjoying all rights, freedom, respect and legal status. Your Lord Rama's father practiced polygamy, Pandavas practiced it, Your Lord Krishna had 16,108 wives officially wholesale polygamy ever recorded, Look into your various scriptures for further details and who practiced polygamy. Hindu kings had scores of official and un-official wives. For Polygamy and Divorce is the blessing from God Almighty. See the condition of your leader's wife - she has been suffering like hell in this world, neither divorced nor recognised as wife - Treated like worse than animal. This is the honour you and your Jumla party giving to the woman as your scripture says - NA STREE SWATANTRYA MARHATI.
Why public interested in personal or religious matter? Is anyone getting harm with these?
Dear sisters, very rarely you will find polygamy system followers in Islam. If they do it is their personal matter and better than prostitution. If any poor lady or someone getting respectful life what is wrong with it. Also remember, they should treat them equally so there is no questions about cheating or insulting.

\Ahmed Deedats Amazing answers to 2 questions\""
Yes, polygamy is better than prostitution. Those who do not know the meaning of verses from Quran try to learn the meaning in your mother tongue then only you will be convinced what is and why polygamy.
dear hindu sisters the moment you know about the rights islam has given to women you will no longer remain to be non muslim, A true muslim, and most majority of muslim men dont treat women as objects it is the non islam religions which are treating women as sex objects, i think for these above ladies prostitution is justified if their husbands do , what a shame and they forget that prostitution with whom they are doing is a daughter, or wife or mother of someone., is it ok for them if someone do the same with their daughter or wife or mother.
ISLAM IS THE RELIGION WHICH IS THE TRUE AND THE ONLY WAY OF LIFE. AND ACCEPTED BY THE CREATOR, SUSTAINER AND THE CHERISHER OF THE UNIVERSE ALLAH THE ALMIGHTY.
BJP is concerned about woman....why they are not concerned about Modi's wife....she has been longing for joining him....why women's right group helping her....and not talking about it.......scared....hypocrites...
