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.

This is not only your question. my question too. that’s why we should end the mhar competition. Otherwise your son also may follow the same path one day.
Masha Allah! it is good to note that some of our brothers brought the globally acclaimed Islamic Scholar to Mangalore.
It would have been more beneficial for the community if the hosts arranged one two public programs in Mangalore and Kasaragod.
Masha Allah Masha Allah happy to see Mufti Menk at our place.Good message to the youth regarding non-competition over mahr.
My Reply to A Mangalorean. Why did your son agree to pay that much Mehr while it was not under his capacity. May be he tried to show his Father in Law that he is also a rich person. Why one should put himself in debt. Now he will have to pay interest on the loan and this is agaisnt the teaching of Islam. We will not put ourself in trouble if we follow simple way tought by our Prophet. May Allah bless us with right way Islam and keep us away from show up.
Hahaha
I m absolutely delighted that Mufti Menk has visited our place and given lecture on Mahr to Manglorean Muslims.
Hoping to see him again and again !!
Good that mufti menk has taken initiative to end mahr competition. Hope it won’t be the beginning of the ‘mufti competition’. Now another NRI businessman in mangalore may think of bringing numan ali khan for next wedding in family (kidding)
Welcome to mufti menk a renowed international scholar to Mangalore. Mufti should advise the rich muslims of coastal Karnatkada to refrain from luxury marriage style with luxury marriage halls and luxury foods.
Unlucky that i was not part of this event. Mufti Sir do visit Manglore frequetly and guide mangloreans who indulged in shirk and diddah... May god bles you, give you good health and long life.
demanding dowry is not islamic culture. he has given series of lectures on that issue. if you want u can google and listen. but what he did here is a timely decision- he pervented show off. why he should talk about non-islamic system of dowry at a wedding where there was no dowry?
A considerable number of Mangalore muslims have adopted the Hindu custom of dowry. But mhar has not disappeared. At the same time among rich muslims there is definitely competition over mahr. This had happened in my son’s wedding too. he had borrowed huge loan to pay a Rs 50 lakh gold as mahr. so I personally feel that Mufti menk’s initiative is good.
Thants Right, instead of speaking about the dowry system which is demanded by the men as oppose to the mahr he is speaking opposite which is very trivial issue in comparison to what a girl's parents suffer.
Barakallau lakumaa wa baarik alaikumaa wa jam'a bainakumaa fee khair. May Allah(swt) bless the new couple. Ameen.
Mahr was never a competition here. Its all peanuts compared to the jwellery the bride wears from her fathers hard earned money. If not that, then its the brand new car in display outside the wedding hall, again brought by the brides father for the bridegroom.
mufti menk has not realised that most of the bearys hav sold themselves to the indian custom of dowry for demand or for self prestige
