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.

Bengaluru, Jan 2: Prime Minister Narendra Modi on Thursday slammed states, which have not enrolled with the Pradhan Mantri Kisan Samman Yojana (PMKSY), saying that such petty politics has done great damage to the farming community.

"I expect that in the new year, those states which are not associated with the Kisan Samman Yojana will at least become a part of it this year," the Prime Minister said at a function in Tumakuru where he disbursed Rs 12,000 crore to six crore beneficiaries under the government scheme in one-go.

Also, he gave away the Krishi Karman Award to the selected farmers and distributed fishing equipment to the chosen ones on the occasion. Modi said political considerations by the state governments in implementing the PMKSY has caused severe loss to the poor farmers.

"Such politics has never strengthened the farmers. Our government understood your (farmers') needs, requirements and your aspirations and accordingly tried to implement the schemes," said Modi.

He further said his government never saw agriculture in fragments but in its totality. Claiming his government has ensured that the entire money reached the poor beneficiaries, Prime Minister hit out at the previous governments, when middlemen ruled the roost.

"There was a time when a rupee was rolled out (by the government) for the poor person, only 15 paise would reach him. The middlemen would pocket the remaining 85 paise. "Today, whatever money is dispatched from Delhi, the entire amount directly reaches the bank account of the beneficiary," he said.

He told the gathering about the various initiatives taken by his government to improve the agriculture sector such as completing the pending irrigation schemes, soil health card and 100 per cent neem-coating in urea.

Due to the initiatives of the government, agriculture production has gone up, he said. Speaking about measures in the fisheries sector, the Prime Minister said the sector has been promoted in the villages, financial help given to fishermen, modernisation of boats and building fisheries-related infrastructure have been done.
