Accept Rs 700-cr from UAE or compensate us: Flood-ravaged Kerala tells Modi govt

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.

Mumbai, Feb 17: The Shiv Sena on Monday said the ongoing preparation for the much awaited visit of US President Donald Trump is a reflection of the "slave mentality" of Indians.

Trump's India trip is like the visit of a "Badshah" (emperor), an editorial in Sena mouthpiece 'Saamana' said.

Taking a dig at the construction of a wall on a plot having several slum structures in Ahmedabad ahead of Trump's visit there, the Sena said the US president's trip would neither stop the fall of rupee's value in forex market nor offer betterment to those (slum dwellers) behind the wall.

"Before Independence, British King or Queen used to visit one of their slave nations like India. The kind of preparations going on from taxpayers' money for the arrival of Trump is similar to it. This reflects the slave mentality of Indians," it said.

The Sena also took a swipe at Prime Minister Narendra Modi over the Ahmedabad Municipal Corporation's (AMC) move to build wall on a plot to "hide the slums" on the route through which Trump's convoy would pass.

"Former prime minister Indira Gandhi had once given the slogan 'Garibi Hatao', which was ridiculed for a long time. It seems now Modi's plan is 'Garibi chupao' (hide poverty)," the Marathi publication said.

Is there any financial allocation for such a wall being built in Ahmedabad? Is the US going to offer loan to India to build such walls across the country? it wondered.

"We have heard Trump is going to be in Ahmedabad for only three hours but the wall construction is costing almost Rs 100 crore to the state exchequer," it said.

It is basically a political arrangement between Prime Minister Modi and US President Trump, the Sena claimed.

Last year, 'Howdy, Modi!' (a mega event jointly addressed by the Indian prime minister and Trump) was organised in the US, it noted.

A similar programme, "Kem Chho Trump" (Gujarati expression for how are you Trump), has been now organised (in Ahmedabad) ahead of the US elections, chiefly because of a sizable number of Gujarati people living in America, the Shiv Sena claimed.

"But this visit of President Trump is neither going to stop further fall of rupee in the forex market nor offer betterment to those behind the wall (being built in front of slums in Ahmedabad)," it said.

The Sena said Trump is "not someone very wise or a statesman or someone who cares for the whole world", but he has to be treated with respect as he represents the mighty US.

"Sometimes you have to treat someone with respect to get your things done," it quipped.

The AMC on Friday said the construction of the wall, around four feet in height, was approved much before Trump's Gujarat visit was finalised.

Trump is scheduled to visit Modi's home state Gujarat on February 24.

He will visit the famous Sabarmati Ashram in Ahmedabad and take part in a roadshow with Modi. After that, the two leaders will inaugurate a new cricket stadium in Motera and address a gathering there, with an expected audience of over a lakh people.

While it was earlier speculated that the programme would be called 'Kem Chho Trump', the Ahmedabad Municipal Corporation on Sunday tweeted a series of posters confirming that the event is now christened as 'Namaste Trump', apparently to give it a pan-India appeal.

Madikeri, Jan 5: Frequent attacks by Tigers on their cattle in South Kodagu region has left the dairy farmers a worried lot and causing concern for their life.

Several farmers have been rearing cows to supplement their income when low prices of pepper and coffee affect their earnings. At least 13 cows have fallen prey to Tigers in the months of November and December last year.

The Forest Department provides a compensation of Rs 10,000 if a cattle is killed by a tiger or in the attack. The compensation amount is meagre when it comes to the loss incurred by the farmers.

Though the Forest Department has submitted a proposal to increase the compensation amount to the government, no action has been initiated in this regard.
