BJP supremo Amit Shah to visit Mangaluru on Oct 4

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, Mar 26: Karnataka Primary and Higher Education Minister Suresh Kumar on Thursday clarified that the SSLC examinations have not canceled as being claimed by many. 

Taking to Twitter, he said there was confusion among students and parents as wrong news was published in a some of the news papers and even in social media also.

Bengaluru, Feb 10: The Rashtriya Swyamsevak Sangh (RSS) on Sunday conducted a route march (Pathsanchalan) in Ramanagara to express solidarity with the anti-Christian forces protesting against a project to install 114-feet tall Jesus Christ statue atop Kapalabetta in Harobele town in Kanakapura taluk in Ramanagara district.

Hindutva ideologue Kalladka Prabhakara Bhat, who had led a rally in Kanakapura last month against the project, also led the Sunday’s route march and addressed a public meeting following the march.

“The district name is Ramanagara, but they have not nurtured the culture of Ram here. They have developed a strong culture of Ravana, which we pledged to dislodge,” Bhat told the gathering.

He said the Sangh Parivar will never allow the statue to come up as he said it would foment religious conversion that is rampant in Harobele.

“The so called Kapalabetta is of stones, which are revered as Lord Muneswara by the Hindus. This hillock must be named as Muneswara Betta,” he added.

Referring to the ongoing protests against the Citizenship (Amendment) Act (CAA), Bhat said the law was brought in to protect the Hindu minority in Pakistan and Bangla Desh.

“The Muslims living in India hail Pakistan. But when we ask them to go to Pakistan, they will never go,” he took a jibe at the minority community.

Reacting to the RSS route march, senior Congress functionary DK Shivakunar, who represents Kanakapura assembly seat, said the Sangah Parivar is trying to disturb the communal harmony in the district and they will never succeed in it.

“The BJP is operating through the Sangh Parivar in the Ramanagara district. The party has won as may as 26 Lok Sabha seats in Karnataka, still they are doing all these things to keep their support base. People of Ramanagara will never back them,” said Shivakumar.
