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.

Kochi, Mar 30: Kerala High Court, while hearing a petition filed against Karnataka's decision to block the border with Kerala, on Monday said that no lives should not be lost in the name of fighting coronavirus.

Kerala High Court also said that "the current problem should be resolved amicably. Both the Union government and the Karnataka government should rise to the occasion."
The Central government has informed Kerala High Court that the movement of goods and medical services qualify under essential services, which is permitted despite the lockdown, and added that directions have been issued to give priority to the movement of such goods and services.
Meanwhile, the Karnataka government has sought a day's time to clarify their stand.

The matter will be taken up for further hearing via video conference tomorrow.
Kerala government has submitted that the action of Karnataka government to close the border is illegal as all the national highways in the country come under the jurisdiction of the National Highway Authority.

Meanwhile, Congress MP Rajmohan Unnithan has also approached the Supreme Court seeking directions to open the Karnataka-Kerala border to allow movement of ambulances and other emergency vehicles for the transport of essential items to Kerala.

Bengaluru, Jun 20: A petition has been filed in Karnataka High Court to transfer Amulya Leona case to the National Investigation Agency (NIA). She raised pro-Pakistan slogans at an anti-CAA rally on February 20 at Freedom Park.

The petition, filed by advocate Vishal Raghu, blamed the probe team for not filing chargesheet on time and suggested the state government to approach the higher court against bail granted to Amulya Leona.

On June 11, she was granted conditional bail by the Bengaluru civil court.

She was charged with sedition for her actions in the presence of All India Majlis-e-Ittehad-ul-Muslimeen chief Asaduddin Owaisi.

The court granted bail after hearing the bail application. Amulya's advocate on behalf of the petitioner said, "the petitioner is just a 19-year-old lady and she is studying in a private college in the Bengaluru. She shouted 'Pakistan Zindabad' but she never mentioned Pakistan as her country."
