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.

I'm a Christian Anglo-Saxon, and I find the idea of this book to be wonderful. For me, it is beautiful to envision Jesus kneeling down to worship Lord Shiva. It is not disrespectful to Jesus at all to believe this - it shows that he was a reverent and faithful believer. As a Christian, I can understand why the people who wrote the Bible might have wanted to cover up certain aspects of Jesus's life. I love the idea of Jesus and his followers uniting with the Indian people in a shared religious heritage.
its not fully acceptable but some of them are true in that book
To increase bjp vote banks they are trying to include Christians under their belt. Like they says jains, , buddist and sikhs are the part of Hindu religion. Which is totally wrong. No jains , budhist, Sikhs, worships Hindu gods.
Writer used to write stories for ram gopal verma. After the flop of RGV sholay remake version of Aag, writer lost his job and published books on jesus to earn money for his livelihood.
thank god he dint say bible was written by waalmiki.
If Savarkar's brother's thinking was so skewed, just imagine how skewed was Savarkar's thinking??? Bade mian tho bade mian, chotay mian subhanallah!!
Dear BABARAO
Kindly give your Script to Sanjay Lila Bansali (SLB).so that he can Make a Comedy Film base on your Script.We will recommend SLB to introduce Subramania Swami as the HERO of this Movie.
Stop playing with the feeling of Christian And Muslim Who respect Jesus Christ.It wont suite for your (RSS) Stupid Idiology.I thought some one will be there among you will certain amount of So called Common sense But where ???? All Same.
GROW UP DUDE
Yes, this is correct. Everyone in the world are Hindus as Hinduis is the only true religion. All the countries around the world were ruled by Hindu kings. white house was vishnu temple, israel knesste was Ram Mandir, Vatican was sita mandir, Bejing was capital of Shiva, tokyo was rest room of Lakshmi, Australia was ruled over by vishnu, Africa was governed by Krishna. Veer Sarkar fore father was ambassador of all the gods and he was travelling in the air without plane.
Really it was good joke... cant stop laughing...he should be awarded with Nobel Prize.... God Bless him ...

Please don't release that book and cause one more imbalance in the community.Tired of seeing killing people in the name of 'GOD' - GOD is just a Invisible Power, nothing else other than this ,we have given him different forms and name and to relieve our mind from stress and to share thoughts n desire we created a god.Once you purge something from mind you will feel relieved.

loughing of the day from RSS yeak yeak yeak
The RSS creatures spreading their wings to the community of Christians and provoking them. These unknown writers RSS have free time for frictions and fabricate. Earlier they were targeting Tajmahal as Tej Mahal, built by RSS king Tej singh. Kutub Minar built by their RSS king Shaktisena so on. And they are spreading romours that the black stone at Haram, Makkah, as Shiva Linga etc.
They have plans to rewrite the history of India for their needs, in many schools run by them are teaching hate history of India, that's the reason they are in collusion with HRD ministry do innovations.
Damm it RSS.
HAA HAA HAA HAA HAA HAA HAA HAA HAA HAA HAA HAA HAA........
Help I can't stop, I think i will go to hospital, My stomach is getting pain.
HAA HAA HAA............................................HAA HAA
This book is the ultimate proof irreparable idiocy/ stupidity of RSS.
Secondly, how the publishers and printers printed it ?
This community will never improve nor succeed, they continue battling until their stupid community remain at large.
We all respect many Hindus, most of them are indeed good.
but this disproportionate venomous creatures spoiling names of good Hindus.
Indeed Hinduism has become a culture, not a religion.
Jusus Peace be upon him was Jewish, he was born in Palestine,
He has no relation whatsoever with man made religion the Hinduism. He was not Tamil, nor Brahmin,
He was miraculously born without father to his mother the Maryam may God be pleased with all of these. He was against wrong belief of plural God. Hinduism has highest number of Gods than its followers. Where as worshipping plural God is totally against true religions of God like Islam and Christianity.

Jesus is one of the mightiest Prophets sent by ALLAH to the face of the earth. If any Muslim does not believe in Jesus pbuh then he is not a MUSLIM.
QURAN explain on all prophetS of God:
Say (O Muslim) \We believe in ALLAH and that which has been sent down to us and that which has been sent down to Abraham, Ismail, Ishaque, Jacob, and to Al-Asbat and that which has been given to Moses and JESUS and that which has been given to the prophets from their LORD. We make no DISTINCTION between any of them and to him we have Submitted (in ISLAM) (Quran - chapter 2 : 136)
The devils which is also a creation of ALLAH will try to claim thru LIES and DECEPTION... But ALLAH says never fear the devils and seek help from HIM. Devils are smart in LIES and Cheddis are following his agenda. which will take them together to HELL which will be eternal...
Those who support such ideology of destruction should learn about ALLAH and his creation the Shaitan from the jinns who has been FOOLING people who are far from the TRUTH>"
RSS PLEASE GIVE US BASE FOR HINDU RELIGION .,...
Hahahaha...many more things to come till Modi in throne, my dear christian brothers don't get exited. All nuts and bolts of sanghis are removed...HAHHAHHAAH
