Sunny Leone all set to enthral her fans in Bengaluru... permission granted, finally

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, May 12: Last week, a 28-year-old, eight-months pregnant woman, was found murdered at her house, in Diburahalli. The woman was hacked to death with a machete during the day and was discovered only after her family members returned home, later in the day. After the alleged murder, the accused tried to destroy the evidence, by cleaning the crime scene, and wiping the bloodstains off the walls and floors.

The victim was a homemaker and her husband is employed in the railway department. The police suspected that the murder was a result of someone known to the woman and family, and were soon proved right. The woman was murdered by her own brother-in-law, frustrated with her for allegedly not taking care of his mother and other family members properly.

The victim has been identified as Jyothi, and the accused is her husband’s brother Hareesh Babu, 38. “Jyothi and the accused are alleged to have had differences for the past few years. Their fights kept escalating over the years. She had also informed her family and her husband about the regular fights with the brother-in-law. The accused had been advised by the family, to back off from Jyothi. Owing to his violent streak, Babu’s wife had deserted him and their son. Since his wife’s departure, he had started troubling his brother’s wife and was regularly picked a fight with her.

He complained that Jyothi neglected to take care of his mother and other family members. Investigations reveal these as false allegations, and in fact, Babu’s son was being raised by Jyothi,” said an officer on part of investigations.

Last week, when the victim was resting at home, the accused returned home at around 10.30 am and picked up a fight with her. The fight escalated and Babu ended up hacking her to death with a machete. The victim’s father Nagaraj, at the time of filing a complaint, mentioned Babu’s regular fights with Jyothi and suspected his role in the murder of his pregnant daughter.

The accused, after killing her, had gone to the farm and pretended to not knowing about the the happenings back home. Based on the complainant’s suspicion, the police picked up Babu. After a thorough interrogation, Babu reportedly confessed to the murder of his sister-in-law. The machete, which was used for Jyothi’s murder, was also recovered by the police team.

A case of murder under section 302 of the Indian Penal Code has been registered and further investigations are underway.
