Bajrang Dal activist thrashed by public for harassing woman

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.

Mysuru, Jan 20: A 100-member team of National Security Guards (NSG) has arrived in the city for bolstering security measures in the tourist centre and to demonstrate the preparedness of the elite force to tackle any exigency in the region.

The annual maintenance of the Mysuru Palace will be taken up on Monday and the NSG commandos are expected to give suggestions and directions for improving the security at the place. It is also said that the commandos may visit Mysuru airport.

It is also said that the commandos may visit Mysuru airport. According to sources, from the Palace Board, the team of commandos reached Mysuru two days ago and interacted with the officials and engineers of the Palace Board.

Hubballi, Jan 30: Seeking to disabuse people of the notion that the Citizenship (Amendment) Act (CAA), recently passed by the BJP-led central government threatened the legitimacy of Muslims in the country, yoga guru Baba Ramdev on Wednesday said that he would among the first to take to the streets should the community face any such trouble. “If the National Register of Citizens (NRC) threatens injustice to Indian Muslims, it I not just I, but a billion Indians will protest against its implementation,” he added.

Recalling his longstanding association with Prime Minister Narendra Modi, Ramdev said, “I have known Modi for more than 15 years, and I can assure you that he cannot be called anti-Muslim. There is nothing in the CAA that threatens the rights of Muslims, some of whom are being misled by a few.”

The yoga guru said that, while 99% of the Muslims in India were patriotic, the remaining ones were seeking to divide the country, which he said was resulting in Islam falling into disgrace. “I appeal to all Muslims to keep away from such anti-national forces seeking to bring a bad name to Islam,” said Ramdev, calling on the people to stay united in the face of the severe economic crisis that the country was presently in the grips of.

He added that he was as committed to his goal of getting black money back to India. However, when quizzed by journalists as to how long he was willing to wait for PM Modi to realise this objective, Ramdev said, “Chodi, mere aur Modi ke beech jagada mat lao (Please do not incite a fight between Modi and me).”

The yoga guru also endorsed the decision of the Centre to recognise singer Adnan Sami with a Padma award.
