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.

Burnol time for some people here.. Welcome to the Original Religion.
mr thogadia several poor adivasi hundus are embrasing islam and christaianity becuase of your caste system in hinduism. try to help these poor hindus.
Oh yeah!!! IN YOUR DREAMS....right.Happy dreaming Togadia!!!
oh, thogadya got wrong information may be 7.5 lakhs were converted to islam
Togadiya you doesnt know that more than 50 lkh non muslims embraced islam in last 8 years.
Whatever tricks they do to reduce Muslims, But, Allah made Islam to supersede all the religions of the earth. Allah is the best planner.
Mr.Togadiya is just following his master's foot step!! nothing new in his statement, Just look @ our honorable prime minister's statement before election and now?? look at our prime ministers statement when he was on foreign tours and when he is in our country!! only these people are fooling us!! don't give much attention for these types of ill mentality what they called leaders!!
Pravin Togadia being JAIN, why he did not convert to Hinduism before converting others to Hinduism?
Is he loosing his mental stability??
Not only Pakistani Hindus, but, they should bring back to India Srilankan Hindus, Bangladeshi Hindus, Nepali Hindus, Mauritius Hindus, Thailand Hindus, American Hindus, European Hindus, African Hindus, Middle Eastern Hindus etc., All the Hindus must come back to Hindustan. So, they will have majority.
its not new thing..........he is not true to himself..as he himself does not belong to HINDUISM. he is a Jain
Common innocent Hindus are fooled time by time.........even in Al jazeera interview Ram madhav told they do follow Hindu culture not Religion
Very very absurd news. Even if it happened, they don't know what is Hinduism and what is Islam, what is Christianity.
Go to Bombay's Maidan where dozens of educated Hindus are accepting Islam in public, without any pressure or greed.
The govt's seems itself shows Hinduism is diminishing and Muslim population is increasing.
Do whatever you want, the God' s real religion will rein for ever,
All man made fake religions will cease.
I THINK THOGADIYA HAD DREAM LAST NIGHT ABOUT THIS ,
PLEASE DONT JOKE TOO MUCH .....
RSS means liars and always lying. foolish people
Fun of the year... will reward him with \FEKU of THE YEAR\"... Jai ho..."
Muslims Worshiping ONE & ONLY GOD ALLAH, The True CREATOR.
ALLAH is the creator of all that exists, Even U Togadia.
Ye Togadia, stop spreading False news, People are not FOOLS to believe what U say.... U are old. Soon people will throw YOU and Your devils will also Forsake U.
Look for the TRUE GOD and ask his Forgiveness...
ALLAH will forgive all Sins if repented sincerely except SHIRK (associating partners with him)
STOP worshiping the CREATION and LOOK for the CREATOR. IF U R HOnest The CREATOR will guide U to know the reality of YOUR Idol Worship...
Muslims will never bow down to idols & shits & urine & monkeys- SiCK people will do such thing...
RESEARCH it if U are intelligent.
I think thogadia is totaly mental, in last 10 years more then 10 lakh Non muslims converted to Islam.
FAKE NEWS AGAIN & ONLY FOOLISH WILL BELIEVE....
