NIA rules out Kasaragod module of IS link to Sri Lanka terror attacks

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, May 27: Karnataka’s twin coastal districts of Dakshina Kannada and Udupi today reported 11 and 9 fresh covid-19 cases respectively.

In Dakshina Kannada the covid-19 patients include seven women and four men who had recently come from Maharashtra.

One of the patients is a 3-year-old child. Others are girls aged 11 and 17, women aged 36, 37, 45, 59 and men aged 22, 35, 39 and 46.

All of them have been shifted to covid-19 hospital from different institutional quarantine centres. 

In Udupi too all the nine people – six men, a boy, and two women -  had come from Maharashtra a few days ago.

Lucknow, Apr 13: Muslims in Uttar Pradesh are now worried that the intense communal profiling of the Corona patients by the official agencies could lead to lynching incidents once the lockdown is lifted.

Muslim scholar and former SP spokesman, Abdul Hafiz Gandhi, on Monday said, "The manner in which the government agencies are identifying persons belonging to Tablighi Jamaat in the list of Covid-19 patients is now translating into intense communal profiling which has been prohibited by the World Health Organization and the central government. A very small percentage of Muslims subscribe to the Tablighi Jamaat ideology but the impression going around is that the Muslim community, in general, is spreading coronavirus."

He said that there was a strong possibility of Muslims, in general, being attacked after the lockdown is lifted.

"This is exactly what happened on the cow slaughter issue. Even a small rumour led to people being lynched by mobs across the country. Corona is a pandemic and should be treated like one. We should fight against the virus together instead of creating a communal divide. Every day, the government spokesman lays down the number of Corona positive cases and then goes on to say how many of them are from Tablighi Jamaat," he explained.

Amir Haider, a social activist and also a veteran Congress leader, echoed similar sentiments when he said, "We strongly condemn the Tablighi Jamaat for ignoring the protocols and holding the congregation but why is the state government repeatedly harping on the religious angle. Shia and Sunni clerics are repeatedly asking the people to adhere to government guidelines and follow safety protocols.

He said that efforts to create a communal divide on the corona issue could have dangerous ramification after the lockdown is lifted."

A retired IAS officer, who did not wish to be named, said, that people have already started objecting to taking home deliveries from Muslim employees.

"My neighbours refused to take delivery of groceries from a Muslim boy. This is just the beginning of the narrative that is being drilled into the minds. We must check this before it explodes into something very dangerous," he said.
