Three suspected Nipah cases surface in Shivamogga dist

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,  Apr 30: As many as 30 new COVID-19 cases have been confirmed in Karnataka from April 29, 5:00 pm to April 30, 5:00 pm, taking the total number of cases to 565, informed the State Health Department on Thursday.

Meanwhile, a total of 1,718 new cases were reported in the last 24 hours, taking the total number of cases to 33,050 in the country.

A total of 630 patients have recovered in the last 24 hours, as per the latest data provided by the Union Ministry of Health and Family Welfare.

Even as the Muslims of undivided Dakshina Kannada district broke out of the “spiral of silence” and made history by leading an unprecedented protest against CAA, NPR and NRC as well as the categorial mistreatment of non-saffronites at the hands of the police across the country, mainstream media turned a blind eye to the spectacle at the Shah Garden Maidan in Mangaluru’s Adyar where about two lakh patriots with tricolor in their hands converged to assert themselves on January 15th, 2020, a date which will be remembered by the people of coastal Karnataka forever.

The largest gathering in the history of Mangaluru was absolutely peaceful, law-abiding and respectful. While the slogans of ‘Azaadi’ were reverberating in the atmosphere, the protesters were seen making way for vehicles and passersby, taking care of women and helping elderly citizens on the highway adjacent to the ground. Though the organisers and most of the participants were Muslims, they collectively identified themselves as “We, the people of India”.

The district administration and the police department hadn’t imagined or even dreamt of such a mammoth gathering after blocking the highway and banning public transport from 9 am to 9 pm. Many opine that this action was taken only to discourage the concerned from participating in the protest and to create fear in the hearts of the people who are yet to process the unjustifiable deaths of two innocent citizens in an unwarranted police firing a few weeks ago.

What has since surprised the protesters most is the mainstream media’s blatant attempt to downplay the significance of this largest ever gathering. Shockingly, it could not make it to the front pages of any of the state-level Kannada daily newspapers except city-based Vaartha Bharathi. In the absence of The Hindu, which had announced a holiday on account of Makar Sankranti, most of the English newspapers too pitilessly buried the historic event in their inner pagers. National TV channels too were evidently reluctant to cover the event until NDTV started telecasting the news of the protest.

This uneasy relationship between the media and minorities in coastal Karnataka has long existed, but the non-coverage of the huge protest of Jan 15 marks a quantum leap beyond the media’s traditional pro-Sangh Parivar stance and biases –– which in the past had often demonised non-saffronites –– to now completely ignore and suppress the people’s voice. This media bias has naturally evoked a sharp response from netizens, who took to social media to issue clarion calls to boycott the mainstream media forever.

Cleanliness Drive

Most major protest meets and rallies –– both religious and political –– leave behind tonnes of garbage, especially water bottles, placards and buntings. However, the organisers of the Jan 15 protest meet led by example by launching a cleanliness drive in the area soon after the protesters left the venue peacefully. The drive continued on Jan 16 too. (Ironically, amidst this ongoing cleanliness drive, a local news portal captured photos of a few plastic bottles scattered along the road at Adyar and published a report accusing the event organisers and participants of polluting the area!)
