Dadri lynching: Allahabad HC stays arrest of Akhlaq's family, except brother

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 21: Taking strict measures to contain the spreading of COVID-19, Dakshina Kannada Deputy Commissioner Sindhu B Rupesh, who is also District Magistrate, ordered sealing of road connectivity leading to Kerala State for all kinds of traffic from March 21 to midnight of March 31.

No vehicles will be allowed to operate between Dakshina Kannada and Kasaragod district in Kerala, the Deputy Commissioner said in a late-night order on Friday.

Ms. Rupesh said that in case of any emergency, vehicles will be allowed only through the Talapady check post on the National Highway 66, which is about 17 km away from Mangaluru city.

The Deputy Commissioner’s order came after the Kasaragod district reported six COVID-19 positive cases on Friday.

The order said that many vehicles operated between Kasaragod in Kerala and Mangaluru and hence, there is a need to take precautionary measures.

Private buses to not ply

Private bus operators in Dakshina Kannada will not operate their buses on March 22 to support the ‘Janata Curfew’ called by Prime Minister Narendra Modi.

Dilraj Alva, president, Dakshina Kananda Bus Operators’ Association, said in a release on Friday that people should remain in their homes on Sunday to help contain the community spreading of COVID-19. The decision has been taken in the interest of the public, he said.

Mangaluru, May 19: In a bizarre incident which exposes the publicity craze of “philanthropists”, members of a city-based organisation returned without disturbing grocery kits after villagers refused to be photographed while receiving them. 

The incident took place at Mukrampady village in Puttur a few days ago. According to sources, a team belonging to an organisation from Mangaluru had visited the village with a letter from their organisation, to distribute grocery kits to families near mosques in the month of Ramadan. 

The team members reportedly insisted the beneficiaries to pose for pictures with the team near a mosque while being given the food kit. The villagers refused to fulfil their wish.

The organisation members then left the place without handing over the Ramadan kits, sources said.
