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.
Morena's Khedakala village made headlines after the people of Muslim community here gave land to Hindus to build 'Sri Ram Janki Temple' in the village.

99% Muslims over all do all haram business.... Monarch is prohibited.. still saudi has monarchism ..... Idol worship is haram... u will find highest darga in India...... Interest is haram... 90% of bank borrowers and lenders are muslims..... highest default and interest payers in bank are muslims ... are Muslims..... ... my dear brothers before saying haram and halal.. first lets be perfect and then talk about haram and halal.....
#ummar,
Idol worshiping is forbidden in Islam, to support it or fecilitate it by any of the way is forbidden or it is like supporting idolatery,,,
Regarding your examples, prayer by Khalifa Umer or any muslim , at any place of clean is allowed , if there is no any idolatery supported images or any articles....and same way in islam , it is forbidden to harm any non muslim worshiping places...as mentioned by your second example...
This is surely Interest money, Bank Interest is Haram in Islam, Many Muslims have disputed land in their posses. these land either they have to give on charity or live for the Govt. So better to give to Ram Temple since Ram temple is very less in our country comparing to Snake temple and Monkey temple...Useless Muslims who did this all of them reserved places in hell surely Almighty Allah will punish them severely Insha Allah...!!!
NA TASYA PRATIMA ASTI... For Sure it means there is no image of GOD.
Ram is a HUMAN and Human has a picture. And U go against the VEDAS.
I think this guy want to deviate the locals & himself far from the TRUE GOD, who says God forgives every SIN except associating PARTNERs with him.
May ALLAH protect us from associating PARTNER with him knowingly & unknowingly.
@pleasant ..
U cannot says suddenly that shirk bec we have example here
some Christian community came to Makkha to meet our prophet saw wen they came they asked the place to pray ... Rasool saw arranged and gave them the plac
They are doing shirk. This is very bad manner.
