Now, Gau Raksha Dal members to go on patrol across Dakshina Kannada

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.

Bhopal, Mar 18: Congress leader Digvijay Singh's detention by police in Bengaluru is display of "dictatorship and Hitlarshahi" by the BJP, Madhya Pradesh Chief Minister Kamal Nath said here on Wednesday.

Singh staged a protest near a Bengaluru resort this morning where rebel MLAs of Madhya Pradesh Congress are staying, and demanded that he be allowed to meet them.

Singh, who has been detained by the police, accused the BJP of holding the MLAs captive and said that he would go on a "hunger strike".

Reacting to this, Nath said if the need arises he would also go to the Karnataka capital.

"Preventing Congress Rajya Sabha candidate and other ministers from meeting MLAs, misbehave with them, forcibly taken them into custody is totally a dictatorship and hitlershahi (sic)," Nath said in a tweet.

"Entire country is watching how an elected government is being made unstable and how BJP is murdering democratic values," Nath said.

"Why they are not allowing them to meet MLAs. What BJP is afraid of. BJP is playing a dirty political game in the state," the chief minister tweeted.

Demanding immediate release of detained Congress leaders, Nath said that democratic norms and Constitutional values are being stifled.

Later speaking to reporters, the CM said, "Why the BJP is afraid of presenting 16 MLAs here (Bhopal)? What is the problem in one person (Singh) meeting with 16 legislators?"

Nath reiterated that his government had proven majority on floor of the House in the last 15 months since coming to power.

Amid political uncertainty in Madhya Pradesh, the state Congress Legislature Party on Tuesday moved the Supreme Court seeking direction to the Centre and the BJP-led Karnataka government to grant it access to communicate with its rebel MLAs staying in Bengaluru.

The apex court had also directed the Kamal Nath government to respond by Wednesday to a plea by senior BJP leader Shivraj Singh Chouhan seeking immediate floor test in the Assembly.

New Delhi, Feb 24: India has deeply appreciated the Senegal government's decision to extradite fugitive gangster Ravi Poojary to India, official sources said on Sunday.

Facilitation of transit provided by the Government of France has also been acknowledged, they said.

Ravi Prakash Poojary, accused of committing a number of serious offences including murder and extortion in multiple jurisdictions, was extradited from Senegal on Saturday.

The probe agencies have persistently pursued the case for his extradition with the authorities in Senegal. India had made a request with Senegal for his extradition in early 2019, sources said.

Poojary was associated with gangster Chhota Rajan, but he also worked for fugitive underworld don Dawood Ibrahim.
