Cong out to win over Lingayats, to push for separate religion tag

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,  Jul 9: Former Karnataka Chief Minister and Congress leader Siddaramaiah on Wednesday said that he was opposed to a tie-up with Janata Dal-Secular in the last Lok Sabha elections but the party high command did not listen to him.

"I had suggested that we should fight alone (in Lok Sabha elections) because JD-S votes would not have come to us and our votes would not have gone to JD-S," Siddaramaiah told reporters here.

Congress leader said that he was the only one to make the suggestion and he did not get support.

"I was the only one to raise a voice that's why it was not heard by (party) high command and I did not get support. We might have won over seven seats in parliament election if we had fought alone," he said.

After forming government in Karnataka in 2018 with support of JD-S, Congress had fought the 2019 general election in a pre-poll alliance with the party. Congress could only one seat of the 21 it contested and JD-S also won one seat of the seven it contested.

Bengaluru, Feb 11: Onion price dropped to Rs 25-30 per kg on Monday, down from the dizzying Rs 200/kg in December and January. The price had spiked because of excess rain, which ruined the crop in several parts of the country.

With supply stabilising, especially from Maharashtra and northern Karnataka, and exports banned, the rate is now easing, officials said.

Consumers may be smiling but farmers are worried as they are not able to make more than Rs 17/kg as against the expected Rs 40.

"We get onions from Nasik and Sholapur in Maharashtra. Nasik onions used to be exported but since that is currently banned, they are landing in Bengaluru, leaving the market here with a surplus," said K Lokesh, president, Karnataka State Onion Merchants Association.

A farmer from Sholapur wh o was part of a onion growers' delegation which met traders in Bengaluru, said, "The cost of everything has gone up. Labour charges and fuel prices are draining us. How can we survive? How can I pay for my children's education?"

Another Sholapur farmer rued: "My daughter's wedding is in March. How am I going to meet all the expenses? I have to pay for labour, transportation, gunny bags and when everything adds up, I don't get to save more than Rs 30,000 in a month."
