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.

Tumakuru, Jul 7: Coronavirus is spreading at the community level in Karnataka, said minister, JC Madhuswamy on Monday.

"Medical condition of eight infected with coronavirus admitted in Tumkur COVID Hospital is critical. There is no guarantee of their lives as per the information. We somewhere feel we are worried that coronavirus is spreading at the community level," Madhuswamy, Tumakuru district-in-charge minister, told reporters here.

"We have reached a point where it is difficult for the district authorities to restrain it, even though we are trying to restrain it. Somewhere the situation is going out of hand," he said.

The minister confirmed that the cumulative toll in the district due to COVID-19 rises to 9.

Earlier, Chief Minister BS Yediyurappa, Deputy CM Ashwath Narayan, Medical Education Minister Dr Sudhakar have denied of community transmission of coronavirus in Karnataka.

According to the Ministry of Health and Family Welfare, there are 23,474 coronavirus cases in Karnataka including 13,255 and 372 deaths.

Feb 25: Two Customs Preventive officers allegedly involved in gold smuggling cases in Kerala were removed from service, a top official said in Kochi on Monday.

Sumit Kumar, Commissioner of Customs (Preventive), Kochi, said that he took action against Radhakrishnan B, Superintendent of Customs, and Rahul, Inspector of Customs, who were allegedly involved in gold smuggling cases in the state.

Radhakrishnan was involved in attempted smuggling of gold weighing 24998.61 grams having a market value of over Rs 8 crore through Thiruvananthapuram international airport on May 13, 2019, Kumar said.

Rahul was involved in attempted smuggling of gold weighing 11,035.54 grams valued at over Rs 4 crore through international airport on August 19, 2019, the Customs Commissioner added.

Radhakrishnan is currently lodged in Central prison, Thiruvananthapuram after the Central Economic Intelligence Bureau under the Union Finance Ministry issued detention order under COFEPOSA (Conservation of Foreign Exchange and Prevention of Smuggling Activities Act, 1974).

Rahul, against whom detention order under COFEPOSA was issued, is absconding.

"Two Customs officers of the Customs Preventive Commissionerate, Kochi, who were involved in gold smuggling cases were removed from service by Sumit Kumar, Commissioner of Customs (Preventive), Cochin," an official release said.

Kumar said that both the cases were booked and investigated by the Directorate of Revenue Intelligence and while show cause notice under Customs Act 1962 has been issued against Radhakrishnan, investigation is under progress in the other case.

"Both the officers were removed from service, after due process of law under Rule 19 of the Central Civil Services (Classification, Control and Appeal) Rules, 1965," the release said.
