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, Jun 1: Prime Minister Narendra Modi on Monday sought a discussion on advances in telemedicine, the use of "Make in India" products in the healthcare, and the use of IT tools in the medical sector for a healthier society.

Addressing an event at the Rajiv Gandhi Health University in Bengaluru via video conference, he sought a discussion on whether new models can be conceived that make telemedicine popular on a larger scale.

Referring to the "Make in India" program, he said the initial gains made in this field make him optimistic. "Our domestic manufacturers have started production of personal protective equipment and have supplied about one crore PPEs to those in the frontline of fighting COVID-19.

Modi said IT-related tools for healthier societies can be of great help.

"I am sure you have heard of Arogya Setu. Twelve crore health-conscious people have downloaded it. This has been very helpful in the fight against coronavirus," he said.

Wuhan, Feb 6: Chinese multinational conglomerate holding company Tencent has allegedly published "real" data on the novel coronavirus deaths, with briefly listing death toll as 24,589 -- way too higher than over 500 deaths China has officially announced to date.

According to Taiwan News, "Tencent... seems to have inadvertently released what is potentially the actual number of infections and deaths, which were astronomically higher than official figures".

Tencent, on its webpage titled "Epidemic Situation Tracker," showed confirmed cases of novel coronavirus (2019-nCoV) in China as standing at 154,023 - over 10 times the official figure given to the world on February 1.

Data leaked: Tencent lists 25,000 deaths in China, 1.54 lakh infections from coronavirus
It listed the number of suspected cases as 79,808, four times the official figure.

"The number of cured cases was only 269, well below the official number that day of 300. Most ominously, the death toll listed was 24,589, vastly higher than the 300 officially listed that day".

Once people noticed this, Tencent immediately updated the numbers to reflect the government's "official" numbers.

"Netizens noticed that Tencent has on at least three occasions posted extremely high numbers, only to quickly lower them to government-approved statistics," said the report.

Some people speculated a coding problem may be behind the real "internal" data but others believe that someone is actually trying to reveal the real numbers.

Tencent was yet to officially comment on these reports.

"According to multiple sources in Wuhan, many coronavirus patients are unable to receive treatment and die outside of hospitals."

There have been multiple reports of Wuhan officials cremating deceased coronavirus victims before they could be added to the official death toll.

The Wall Street Journal reported that the coronavirus numbers coming out of China are "fishy".

If the numbers from the alleged Tencent leak are accurate, it would put coronavirus' mortality rate at almost 16 per cent. By comparison, SARS' mortality rate was 9.6 per cent, reports CCN.

Caijing, an independent magazine based in Beijing that covers societal, political, and economic issues, has also claimed that the Communist Party of China (CCP) is underreporting the extent of the coronavirus outbreak.

Caijing's article on Coronavirus that detailed how Wuhan officials are not reporting real figures was censored in China.

As of Thursday, the official death toll in China rose to 563, with 28,018 confirmed cases.
