Hadiya case: No court can annul marriage between two consenting adults, says SC

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.

Mangaluru, Apr 13: City Commissioner of police P S Harsha on Monday warned people, not to use drones illegally for filming or any other purposes.

Speaking with this regard Harsha said on Monday ,''“We have noticed that persons are illegally using drones to film Mangaluru city. If this continues, we will not only seize the drone but will also take firm legal action against the person responsible. Because Mangaluru is a sensitive place with lots of vital installations.''

He further requested the media houses also not to hire drone services for filming or any other purposes.

Bengaluru, Feb 18: Deputy chief minister Laxman Savadi was elected to the legislative council on Monday and although it was a done deal that he would win, a vote from across the aisle spiced up the election.

Counting was conducted soon after ballots were cast and Savadi polled 113 of the 120 votes cast, including the vote of disgruntled JD(S) legislator GT Devegowda. Seven votes were declared invalid. Members of the two opposition parties — Congress and JD(S) — abstained from voting.

The election was necessitated following the resignation of Rizwan Arshad of the Congress. Rizwan resigned after he was elected to the legislative assembly from the Shivajinagar constituency in the assembly bypolls held for 15 seats in December last year.

BR Anil Kumar, who was initially promised the support of both Congress and JD(S) was supposed to contest as an independent candidate. However, as both parties refused to support him at the last minute, he withdrew, paving the way for Savadi’s victory.

The BJP has 117 members in the 225-member assembly, but N Mahesh of the BSP and two independents, H Nagesh and Sharath Bachchegowda, besides GT Devegowda also voted, taking the total electorate to 120 (including the speaker). BJP’s SA Ramadas did not turn up because of health reasons.

“I would like to thank all those who were responsible for my victory. Special thanks to leaders of my party and chief minister BS Yediyurappa, who gave me the opportunity to be the BJP candidate,” said Savadi.

Winning this council election was crucial for Savadi to retain his ministry as he was not an elected member of either of the houses. Rules mandate that a non-member must get elected either to the assembly or council within six months after taking over as minister. February 20 was the deadline for Savadi, who had lost 2018 assembly polls from Athani, to get elected.

Officials in the assembly secretariat said seven votes were invalid because voters had wrongly marked their choices on ballot paper. According to norms, a voter has to mark numerical one, two and three against the names of the candidates in order of preference. Marking only numerical one is allowed. However, six ballots had a tick mark, while a voter had registered a cross mark. Since it was a secret ballot, it was not known who the MLAs were whose votes were invalid.

“The ballot papers bear serial numbers and they are randomly distributed. It is virtually impossible to say who a voter cast his or her vote for,” said assembly secretary MK Vishalakashi, the retuning officer for the bypoll.
