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.

Your topic is outdated... people know your evil intention to make peaceful hindus and muslims fight each other..
It would be better for you to look Who is our CREATOR and how he wants our life to be lived rather than only creating evils in the society...
the word 'Hind' in arabic means 'India\.. in that context , what he said is correct.. all indian nationals are Hindu nationals , irrespective of their religion.. there is no religion named 'Hinduism\"
Name 'hinduism' term used by british for easy survey.. other than Muslims and christans, all others included under 'hindu' label."
Mr. Chaddi guru please shut up your mouth. Suggest to think at least 5 times before your speak
India does not belong to any communal group. Only freedom fighters and their alliance permitted to give any comments advise. chaddi desh drohi has no right to talk about HINDUSTAN.
Jai Hind!
Who r u to decide who is who?
If u go to Kerala and Tamilnadu they don't understand word Hindusthan....He He He....
So Modi slogan India First will change to Hindu First. Eventually it will turn to sangha first. Looks like he is on drug. RSS has accumulated and looted large sum of Indian money since Modi came to power. CBI has to investigate every RSS member account.
I dont find anything wrong in this . Ofcourse we can also be called Hindus .as Hindusim is not a religion , it is a way of life and people staying in a geographical area ..we Muslims have lot of tradition and culture imbibed by our hindu ancestors , dargah worhsip is also one among that ... we are hindus Mr Mohan bhagwath ... hindus or bharatiya is fine with me . you guys belongs to sanathan dharma ... we belong to islam .. but i strongly believe we are hindus ...
WHO IS THE HELL YOU TO DICIDE, YOU ARE A JUST TERRORIST GO AND FIGHT IN BORDER,
I am working is Gulf.... and every Indian here is called HINDI irrespective of which religion he belongs to... So what's a big deal...
By the way Hindu/Hindus is not the real name of the religion. It is called Sanathana Dharm... Unfortunately loads don't know this fact.
Hindu/Hindus is the name given by foreign invaders who came to India in the past.
Correct me if I am wrong
Which nationality his balls belong ???????????????????
Ajjer na posa raaga surand.......aklakulu benpunu aklakul thinpunu hindu aanda daane muslim aanda daane ? .ajjere jankle badhkare budle...chaddi nuppu korpujji....
Its Great to hear from him Mr. Bhagavat about Hinduism why he reminded only about Muslims( may be upcoming UP Election) why not Dalit and Cristians why he spared them from Hinduism by the way if you study the deep root of Hinduism you will never find its a religion its a practice of all culture and morals of the land called Hindustan those who were living in the bank of Sindh and mohanjedaro in the earlier centuries used to calls Hindus people. Now RSS want to re write the history of Mughal kings are may be called Hindu emperors the easy example like Akbar the great.
In the first place this person and his RSS supported British rule in India then what the hell is he knows about Hindu culture.....afterwards his party man killed Mahathma Gandhi....terrible people......but he does not have any right to teach Muslims what to do and what not to do.....Muslims know how to respect one another's religion and tradition....He should mind his own business....
Mohan Bhagwat should be an Indian and respect all Indians first. He should denounce statements from various sanghis on patriotism of non-Hindus. Mohan Bhagwat should respect Indian constitution and urge all the hate mongers to respect it.
Poor old man does not know what & who is a HINDU. It is nowhere mentioned in the so called scriptures they believe. After all the name HINDU was given by MUSLIMS. Pack of Jokers!!!
People live in France are called French
People live in Briton are called British
People live in Indonesia are called Indonesians.
This Sanghi have no idea at all what we call ourself?
Those live in India are called as Indians
Those live in Bharath are called as Bharatiya
Those live in Hindustan are called as Hindustani
Not all Hindus. But, we have a majority population who are Hindus.
Do not forget that all mankind born as Muslim... (Adam A.S)
Take time to study about Islam....
