Cops avert murder and communal riot by arresting Bajrang Dal leader, associates

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.

Bidar, Feb 15: Leader of the Opposition in the Assembly Siddaramaiah on Friday demanded the State government to withdraw the sedition case against a mother and a teacher of Shaheen school immediately.

“The police can’t execute anything without the government’s permission. The sedition case against two women should be withdrawn immediately. I will raise the matter in the Assembly to draw the government’s attention,” Siddaramaiah told reporters after meeting the woman at the prison here. 

He clarified that he visited the woman not to support the school, but to extend moral support to her.

“I am an advocate and I can clearly establish based on my experience that staging a satirical play doesn’t amount for sedition. It doesn’t even defame anybody. Three cases of sedition have been registered across the state,” he charged.

He alleged that the government was following dual policy. Though the Supreme Court had concluded that the demolition of Babri Masjid was illegal, a play dealing with the demolition was staged at Kalladka Prabhakar Bhat’s school.
The sedition case had not been registered for staging the play.

He charged that there was an undeclared emergency in the country as the freedom of expression was being suppressed.

Bengaluru, Jan 6: Students and teachers from various colleges in Bengaluru gathered at the Town Hall in the city to protest against the violence which broke out at the Jawaharlal Nehru University (JNU) campus in New Delhi on January 5.

The students raised slogans against Home Minister Amit Shah and Delhi Police.

Placards that read 'The more you attack, the stronger we become', 'Take off your masks terrorist', 'With JNU' were seen during the protest.

"We are here to protest against the incident that took place at JNU with our brothers and sisters. What Delhi Police did was shameful and they should have taken charge of the situation long before and not waited for three hours. We stand with JNU," Nisha, a protestor told ANI.

Professors present at the protest expressed regret over the incident and said attacks on the universities is a sick situation in the country.

"This is sick, where have we come to -- violence in the universities? I was so safe when I was studying in college; what we are giving to our students is horrible," said Sangeeta, a professor present at the protest.

Politicians, cutting across party lines, have condemned the attack on students in JNU and demanded strict action against those found guilty.

More than 18 students were taken to the AIIMS Trauma Centre after a masked mob entered the JNU campus and attacked them and some professors with sticks and rods.
