I have embraced Islam. It’s my decision… For my happiness: TV actress Dipika Kakar

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.

New Delhi, Feb 6: BJP MP Tejaswi Surya said on Wednesday that the majority community has to remain vigilant or Mughal rule will return to the country, as he slammed the anti-CAA protest at Shaheen Bagh.

He was participating in the debate on Motion of Thanks on the President's Address in Lok Sabha.

Referring to the ongoing protest at Shaheen Bagh against the Citizenship Amendment Act, he said, "Unless majority community remains vigilant, the days of Mughal Raj may not be far away."

Surya also praised Prime Minister Narendra Modi for resolving several critical issues which had been pending for several decades.

The CAA, he said, was aimed at resolving the issues emanating from Partition and added, "The new India cannot to built without healing the wounds of the past."

He said that the CAA was about giving citizenship to persecuted minorities in Pakistan, Bangaladesh and Afghanistan and not for taking away anyone's citizenship.

Under the leadership of Modi, Surya said, several issues of the past have seen closure. These include abrogation of Article 370, construction of Ram temple, Bodo problems and abolition of Triple Talaq.

K Sudhakaran (Cong) said that a time when the economy was going through its worst phase and unemployment was high, the President in his speech talked about making India a USD 5 trillion economy by 2024.

On the comments of the government functionaries that fundamentals of the economy are strong, he said the same expression was used by the then US President George Bush, days before the collapse of the America's iconic investment banker Lehman Brothers.

Not only that, Sudhakaran said even before the Great Depression, the then US President used to say that fundamentals of their economy were strong.

Anupriya Patel (Apna Dal) demanded that the government set up All India Judicial Services Commission to ensure representation of the backward community in the judiciary.

Khagen Murmu (BJP) regretted that West Bengal government was not implementing the welfare schemes of the Centre in the state.

Badruddin Ajmal (AIUDF) said that people of all communities have fought for freedom of the country and it would be incorrect to declare everyone opposing the government's policies as 'gaddar' (traitor).

He said that the government should talk to people protesting against the CAA at Shaheen Bagh and other places, and explain the provisions to them.

Shrirang Appa Barne (Shiv Sena) demanded that the ruling party fulfil all promises it had made to the people of the country.

He regretted that although the government promised to double the income of farmers by 2022, farmers were still committing suicide.
