Kalladka Bhat, swamijis among 800 take part in Swacch Mangaluru Abhiyan

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, Jan 2: Accusing Prime Minister Narendra Modi of "neglecting" Karnataka ahead of his visit on Thursday, the state Congress questioned why he did not give adequate relief and pay a visit to the state, when most of its parts were affected by severe floods last year.

Modi will begin his two-day visit to the state on Thursday afternoon.

The Congress' Karnataka unit in a series of tweets also questioned the Prime Minister about not conferring the "Bharat Ratna" on Shivakumara Swamiji of Siddaganga Math, who passed away last year at the age of 111 years.

"Why you did not visit the state, when it was affected by floods? Despite the damage of over Rs 1 lakh crore why you did not declare it as a national disaster? Why you did not give interim relief? When the state government has given a report that the damage caused was to the tune of Rs 35,300 crore why did you sit quiet by giving just Rs 1,200 crore," the state Congress tweeted.

As many as 103 taluks in 22 districts of Karnataka were affected due to unprecedented floods in August, in which over 80 people were killed.

Around seven lakh people were shifted to safe areas during the deluge and thousands of houses were damaged.

In October, various parts of the state faced a deluge for the second time in two months, killing over 13 people and damaging thousands of houses.

Asking as to why the Centre was not giving the state's share of GST amount adequately, the Congress questioned as to why dues under MNREGA programme were not paid so far, and why Karnataka was being neglected while allocating grants.

Questioning Modi as to why he did not visit Tumakuru when Shivakumara Swamiji of Siddaganga Math passed away, the principal opposition party in the state Assembly, also sought to know why the seer was not conferred with the Bharat Ratna yet.

It also pointed out that former Chief Minister Siddaramaiah had written a letter in this regard in January 2018.

The Congress has also hit out at the BJP-led Central government over imposition of Hindi language by neglecting regional languages and mother tongue.

The Prime Minister will kickstart his visit to the state by paying tributes to the late pontiff's 'Gadduge' (final resting place) at the Math premises near Tumakuru.

Later, he will attend an event organised to give away Krishi Karman awards and to distribute fishing equipment at the government college ground in Tumakuru, before leaving for Bengaluru where he will be attending a DRDO event.

On Friday he will be inaugurating 107th Indian Science Congress here.

The rapid spread of COVID-19 across the globe has thrown movement of lakhs of travelers off gear. This has not only impacted pleasure trips of tourists but also business travel resulting in monetary losses worth millions.

*United, Air Canada, JetBlue, Alaska, American Airlines, Delta, Brutus Airways have suspended flights to China and reduced operations in countries with high Coronavirus infections such as Italy

Domestic airlines:

There have been no restrictions on domestic travel, so far.

What advisories have been issued by authorities that can affect your travel plan :

*From March 9 midnight all air travellers having visited or arriving from Italy and South Korea will require to submit a certificate of having tested nagative from health authorities -designated lab in their countries for Coronavirus at the departure.
