‘Communal forces adopting ‘guerilla’ techniques to disrupt peace’

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.

Bengaluru, Jun 8: The Janata Dal (Secular) on Monday announced that former Prime Minister HD Deve Gowda has decided to contest the forthcoming Rajya Sabha elections.

"Former Prime Minister HD Deve Gowda has decided to contest the Rajya Sabha elections at the request of our party legislators, Congress President Sonia Gandhi and many other leaders of the country. Tomorrow, he will be filing nomination for the election. Thanks to the former PM for agreeing to everyone's consensus," JDS leader HD Kumaraswamy said.

The elections to fill the vacant 18 Rajya Sabha seats from seven states are scheduled to be held on June 19.

Four Rajya Sabha seats are up for grabs in the state, Congress has already nominated senior leader Mallikarjun Kharge as its candidate.

Mangaluru, May 24: Muslims across coastal Karnataka today observed Eid Al-Fitr by offering Eid prayers at home instead of mosques and Eidgahs.

For the first time the cities of Mangaluru and Udupi wore a deserted look on the day of Eid. Strict implementation of the lockdown was seen in the both cities. All vehicles except those transporting essentials remained off the roads.

Following the orders of orders of the deputy commissioners of the Dakshina Kannada and Udupi and guidance of religious scholars and Qadhis, Muslims preferred not to venture out of homes on the day of Eid. The 36 hours of complete lockdown which came into force yesterday at 7 p.m. will relaxed tomorrow morning at 7 a.m.

The Eidgah at Light House Hill area of the city and other prominent mosques, where thousands used to gather to offer namaz during festivals, were empty today.

Photos of simple Eid celebrations were share on social media to keep the spirit of festival alive in times of pandemic.

This time Muslims in the region had also decided not to buy any new clothes for Eid. Campaigns were run in the moth of Ramadan to encourage the Muslims to donate the amount of new clothes to the needy instead.

Throughout the month of Ramadan Muslim organisations were distributing food among the stranded migrant labourers in the region.
