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.

You have mistaken Sanathan Dharma. We are the true followers of Sanathan Dharma which prohibits Idol Worship.
We recite Gayathri mantra 17 times in our prayer. Rigveda 3-62-10
It is the first chapter of the Quran.
It has to be logically from One Supreme Creator who has no Image. Creator who is unlike His creations. Understand the Truth. Study your scriptures learn sanskrit come back to the Truth.
Because Truth is going to succeed and falsehood is bound to perish
She has come back to the Sanatan Dharma
Happy married life for couple. Burnol+ itch guard to naren Singapore.
Best decision from her side, congrats
Naren bhai ... u have mistaken !!!! The picture what cd published here is her old picture when she was a piece , in sha allah we can see a peacefull picture of her in the future with the hijab
MADHUVE JAYANTI FOR BOTH...AND BURNOOL JAYANTI FOR CHADDIS.
If Muslim girl elopes with Hindu boy, police intervene to unite them. Here, the case is vice versa and the same police are separating the couple. What a tragedy.
her t shirts speaks alot she left peaceful religion( sanatan dharma) and joined piece piece religion :) hahaha ... not a loss,its two way process ... but NIA must track these guys becoz converts are used in ISIS .We know 21 neo converts joined ISIS from kasragod . there is chance of waging jihad against own country
This love, staying with a girl before marrieage, and dont know the islam , Quran and hadith. Simply enjoying in duniya is not the behaviour of true muslim. They are spoiling their life here and here after even took birth in muslim family and have a name of muslim. and also they are spoiling the name of our muslim community. Our prophet Muhammad(PBUH) Said, a Muslim sweeping lady is better than other non muslim girls to marry.
made for each other.
let them lead their life. good or bad finally they are the one who suffer.
giving birth , giving education , love and everything by the parents and finally the girl is saying that i don't want parents and the boy who poses like Salman Khan is her choice.
she will repent one day.
at the moment let them both enjoy....
Wher is my comment?why you do not posted my comments?is there any mistake is there? please CD dont show double standeard becouse im one of the reguler reader..
This is the result of advanced tech. Parents has to check their all mobile no.s which has fake names i.e real boys name as girl's name (dummy) and incoming calls blocked by lovers. Only user will unlock during parents absence.
parents are not much educated enough to the effect of Facebook and whatsapp. If you want to provide phone to your children give them simple phone where they can not download illicit apps
May Allah (SWT) guide the couple with hidaayah!!! We should not blame them. Islam is not dependable. Enough preacher for Islam.
Congratulations Girl for the best decision.
Police dept to call both both parents with them and discuss face face and try to solve with in their limit and both elders satiso actiso action.
Interference of any dirty criminal groups, anti Indian groups or any communal mind political leader or their organized goonda group department must take strict action and send them behind bar at least for one year period for igniting communal tension.
Trust this will spoil all trouble makers intention and their political benefit gains.
irrespective of religion all middle class citizens are suffering with present red currency exchange procedures. In between communal mind politicians creating problem and planning communal tension is not faith.
God will never accept thought.
Jai Hind!
Well she should not be blamed it is bcoz of unproper teaching if she know teachings it would not had happened
Congratulations to the couple, leave in peace, take care of each other.
we respect all the religions, but above all it's love. loving each other is more important than anything else. They have won the love, may god bless you, LOVE IS GOD.
Cute Couples, happy married life to both.
