Sid tears into PM Modi, slams BJP for terrorizing minorities, making communities fight each other

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 13: In an attempt to avoid the ugly scene of migrant workers walking to their native places due to the current week-long lockdown imposed in the state, the Karnataka State Road Transport Corporation (KSRTC) is running 1,600 additional buses on Monday and Tuesday to help them return safely.

The KSRTC has already run 249 additional buses from the State capital and has so far ferried 6,641 passengers and 231 buses have been booked.

The KSRTC appealed to the public not to panic as additional buses have been deployed. "After ensuring social distance and conducting thermal screening, passengers will be allowed to travel. It has already been planned to operate additional buses," the corporation stated in a press release here.

Bengaluru, Jan 10: The National Commission for Scheduled Tribes (NCST), which met with officials of the Social Welfare Department Thursday, has urged the state government to increase the reservation provided to the ST community.

The Commission's suggestion comes even as a committee headed by Justice Nagamohan Das is currently studying a demand for increase of reservation for the community from the existing 3% to 7.5%.

Addressing mediapersons on Thursday, Commission Chairperson Nand Kumar Sai, said the Commission had discussed the issue with the Social Welfare Department, Karnataka, asking officials to expedite the process.

In response to this suggestion, Social Welfare Department Principal Secretary G Kumar Naik said the government would take a call based on the Nagamohan Das Committee's report.

A meeting was held between members of the National ST Commission and the Social Welfare Department Thursday with regard to various projects taken up by the department.

In June last year, the then Kumaraswamy-led coalition government constituted the Justice Nagamohan Das Committee, after protests from members of the Valmiki community for an increase in reservation to 7.5%. At present, Karnataka provides 15% reservation for SCs, 3% for STs and 32% for other backward classes (OBC).

The national commission also urged the state government to ensure permanent faculty in all the 824 residential institutions run by the department. At present, as much as 50% of the faculty in these institutions have been hired on a contractual basis. "We have assured that the recruitment will be done in a short time," Naik told mediapersons.
