Wipe out Islam, says BJP MP Anant Kumar Hegde; video goes viral

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, Jun 11: A love triangle took a violent turn when a final-year engineering student was assaulted by both her current and former lovers. She's now battling for her life in the ICU, police said. 

For the 22-year-old woman, who lives in Sidedahalli, it was a case of fast-changing relationships. She broke up with a fellow student Babith, 21, a few months ago after having dated him for four years. Four months ago, she started seeing another collegemate named Rahul, 22, and everything seemed fine. 

On June 7, she went to Rahul's house, ostensibly for his birthday party, after informing her parents. Babith got wind of it and barged into Rahul's house. The trio got into an argument, and Rahul abused and assaulted her. 

The woman decided to leave him, and went with Babith to his house in Chikkabanavara, North Bengaluru. But things didn't end there. Babith picked an argument with her. Things became so bad that he attacked her with a helmet. 

He then panicked and called her parents, asking them to take her home. When her parents arrived, they found only Babith, his mother and sister in the house. Babith's family directed them to a bedroom where she was lying motionless, with her face being badly wounded. 

When her parents demanded to know what had happened, nobody responded. They took her to a hospital where her condition remains serious. A while later, Babith came to the hospital and gave her parents the key of her scooter. He told them what had happened and allegedly warned them against filing a police complaint. 

Her mother, however, filed a complaint with the jurisdictional Soladevanahalli police. According to her, Babith had fought with her daughter at their house for not taking his phone calls six months ago. 

Shashikumar N, Deputy Commissioner of Police (North), said both the men had been arrested and that further investigations are underway. 

Mysuru, Feb 29: Tension prevailed at Tandavaput Industrial Area in Nanjangud taluk, Mysuru when a paper factory received a bomb threat call, which later turned out to be a hoax call.
