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.

The life of this world compared to the Hereafter is as if one of you were to put his finger in the ocean and take it out again, then compare the water that remains on his finger to the water that remains in the ocean. Prophet Muhammad sallallahu alaihi wa sallam, Sahih muslim.
Winning the love of makhlook and getting the hatred of the Khaliq in return is a very bad deal. Insha Allah we will live in this duniya for maximum 100-150 years. The we have to face Allah. What will you reply to Allah? You think doing such things will benefit you, give you izzat. Please understand that benefit, loss, izzat, zillat, disease, shifa all are from Allah alone. Keep Allah happy. These makhlooks cannot do anything for you. If you win the whole world and Allah is angry with you then its very bad. If you win Allah and then even if you get nothing in the world, it is the best deal in the world.
Brother Abu Bakar, we want you and all muslims to go to Jannah and avoid jahannum. Please say the kalima once and read tauba namaaz with a sincere niyat of not doing such kind of deeds again.
May allah give 'hidaya' to these so called 'muslims'
Lack of religion knowledge for this Organization, to bring peace and harmony between different community, to win other communities heart just follow our Prophet's way, even look at other great historian traders like Malik al Dinar / great Muslim Scholor like Kwaja Moinuddin Chisty, how they won other communities heart.
Innala Lillaahi Wa Innaa Ilahyi Raajihoon
Well Done Muslim Brothers.. This should be the way to spread message of peace and harmony. Don't follow the people who copycat Arabs thinking they are following true God. Nothing is proven yet. Don't worry keep the good work going.
Inna Lillahi Wainna Ilaihi rajioon. Muslims left the work of dawah to non muslims & indulging in shirk. Whatever Horekanike you have given is totally Haraam and the sad thing is that people who are doing they are expecting good from others but not from Allah. Haji abubakar parkala, Name indicates that he might have done HAJJ. What is the use of Hajj if they do shirk with allah. May allah give us hidayath.
Dear all,
People of this organisation(UDMPSS) neither muslims nor Hindus, they are only pretending, they can't be trusted anywhere!. beware of them.
These foods should distribute to the poor... they will make dua for the committee... THESE FOODS WILL BE THROWN TO THE GARBAGE AFTER 2-3 DAYS..... NOR THEY WILL EAT NOR THEY WILL DISTRIBUTE TO POOR.... USELESS FELLOW
NOW NEXT HINDUS TURN TO SHOW TO PROMOTE HARMONY...
THEY SHOULD DISTRIBUTE COW TO MUSLIMS AT THE TIME OF BAKRI EID.....
This is really a crazy.....not good at all.....common guys there are many poor Muslim children who are suffering from malnutrition....go and distribute this food items to them....instead of this chaddi worthless creature....this is really a tragedy...
The committee should also know that Swamy was all alone went to Ayodhya from Udupi to demolish Babri Masjid. Which was the main reason behind the communal riots and communalism started in throughout India till today.
Now some Swamy's personal benefited chelas are doing in the name of muslims. Shame on you.
We muslims should keep good relations and harmony with other communities by providing food, shelter, cloths , medical aids to the poor daliths, hindus and Christians but not to give the billionaire Swamy who is always against other communities including daliths.
Next time you can do kola and parba too...
Innaa Lillaahi Wa Innaa Ilaihi Raajiwoon
NAUZUBILLAH
