23 Sangh Parivar, 8 DYFI activists arrested over post I-Day violence

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, Jan 2: The Congress leadership in Delhi is expected to start the process of selecting a new party chief for Karnataka next week. There are strong indications the race has narrowed to DK Shivakumar and MB Patil.

Party insiders said the leadership almost finalised Shivakumar’s name as the president of Karnataka Pradesh Congress Committee (KPCC), but the decision was put on hold after requests by some senior members.

“It’s not that we are against Shivakumar. We think the party should have a Lingayat at the helm since community strongman and chief minister BS Yediyurappa is at the fag end of his long political career. There’s an opportunity here for a Congressman to occupy that space,” said a senior Congress politician, who didn’t want to be named.

That’s where the candidacy of Patil, a Lingayat, scores high.

The party, however, doesn’t want to compromise on quality and wants an efficient KPCC president who can unite two rival factions within the party, one led by Siddaramaiah and another by former union minister KH Muniyappa.

The need to pick a new state president arose after Dinesh Gundurao resigned from the post last month, taking moral responsibility for Congress’s poor showing in the byelections. Siddaramaiah also stood down as Congress party legislature leader.

The insiders said the new KPCC chief could be announced after January 16. The party might also appoint two working presidents and a new legislature party leader, who will automatically become the opposition’s voice in the assembly.

For the latter position, the name of senior Dalit politician and former deputy chief minister G Parameshwara is doing the rounds. But the party, the sources said, could still ask Siddaramaiah to reconsider his decision and stay on.

Many Congress members had raised questions over his stewardship after the bypoll disappointment. They said on his watch, the party had also fared badly in the assembly and Lok Sabha elections, demanding that he be held accountable.

Siddaramaiah is expected to visit Delhi next week to discuss the leadership issue with party boss Sonia Gandhi. Some other senior Congress members, including BK Hariprasad, are also likely to meet her.

Mangaluru, May 31: The bus services by private operators in Dakshina Kannada and Udupi Districts will begin from tomorrow (June 1) with 15 per cent hike in the fares, Canara Bus Owners Association president Rajavarma Ballal said on Sunday.

In a statement issued here, he said that the members of the Association have appealed for a 3-month tax break. ''We have received tax breaks for 2 months and have demanded for an additional month again,'' he added.

He said that the government has agreed to a 15 per cent hike in bus fares. All the passes issued already will be converted into cash cards and no discounts will be available till the end of the COVID-19 crisis.

An added attraction in private buses will be the option of paying travel fares through smart cards.

According to Dakshina Kannada Bus Operators Association president Dilraj Alva, 50 per cent of 325 private city buses will resume their services on Monday. It also meant that 50 per cent of buses will operate on the allotted routes.

The smart cards (or travel cards called Chalo Card) will not be introduced on all routes at a time. They will be introduced in a phased manner covering all routes from Monday.
