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.

Mangaluru, Mar 12: Deputy Commissioner Sindhu B Rupesh on Thursday said that the test reports of the 35-year-old passenger from Dubai have shown no signs of either Coronavirus (COVID-19) or H1N1.

In statement issued here Ms Rupesh said that the passenger has now been discharged from the Bantwal hospital. He has been asked to stay at home quarantined for the next 14 days.

The passenger, who had been diagnosed with fever after he arrived at the airport from Dubai on March 8, had left the Government Wenlock Hospital in the early hours of March 9 refusing to undergo tests.

Later, he was traced and admitted to the hospital in Bantwal and his throat swab samples had been sent to Viral Research Diagnostic Laboratory (VRDL) in Hassan Institute of Medical Sciences.

Meanwhile, throat swab samples of six patients were also found negative for COVID-19.

As many asf 49 people were under quarantine in the district of which five have completed the 28-day cycle.

All passengers arriving by international flights and those in contact with them should voluntarily report to the district health team and undergo self-quarantine for 14 days. If there were symptoms of cough, cold and fever, they should undergo tests for COVID-19. If the reports were positive for COVID-19, then they have to stay in the isolation ward of the Government Wenlock Hospital or in the seven select private hospitals for 28 days.

Screening facility at the airport has been strengthened by posting doctors from seven private medical colleges on rotation basis. These doctors would be in addition to the medical officer at the airport. An ambulance has been placed at the airport exclusively to shift people to the hospitals, she added.

The State government has issued a notification on Wednesday authorising Deputy Commissioners to get the affected admitted by force, if necessary.

Bengaluru, Mar 21: Central Crime Branch (CCB) sleuths have nabbed a three-member Irani gang, including a woman and recovered from them 1 kg 33 gram stolen gold chains worth about Rs 40 lakh.

City Police Commissioner Bhaskar Rao told newsmen here on Saturday that the arrested were identified as Abujar, Abdul Hussain and Ms. Jenia, all hailed from Bhopal in Madhya Pradesh.

He said that the culprits, who had been arrested on similar theft cases, were out on bail and continued their criminal activities. They were involved in more than 23 cases.
