Mangaluru: BJP leaders caught red-handed while smuggling stolen cow?

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, Feb 21: The Supreme Court in its interim order on Thursday allowed the plea of the Karnataka government for implementation of the final award by a tribunal for sharing of water between Goa, Karnataka and Maharashtra from the Mahadayi river.

The interim order was passed by a bench comprising Justice D Y Chandrachud and Justice Hemant Gupta after hearing the counsel from the three states. The bench said the final hearing in the matter will take place in July.

It also said the interim order is subject to the final outcome of the petitions filed by the three states against the tribunal's award.

The Mahadayi Water Dispute tribunal had passed the order on August 14, 2018, allocating 13.42 TMC ( Thousand Million Cubic Feet.) water (including 3.9 TMC for diversion into the depleted Malaprabha river basin) from the Mahadayi river basin to Karnataka.

Maharashtra was allotted 1.33 TMC water while Goa was given 24 TMC in the final decision of the tribunal. The UPA-2 government had constituted Mahadayi Water Disputes Tribunal in 2010.

Karnataka government, which has locked horns with the neighbouring Goa on the larger issue of sharing Mahadayi River water between both the states, had petitioned the tribunal seeking the release of 7.56 tmcft of water for the Kalasa-Banduri Nala project.

The Kalasa-Banduri Nala (diversion) project, which will utilise 7.56 tmcft of water from the inter-state Mahadayi river, is being undertaken by Karnataka to improve drinking water supply to the twin cities of Hubballi-Dharwad and the districts of Belagavi and Gadag.

It involves building barrages across Kalasa and Banduri, the tributaries of the Mahadayi River, to divert 7.56 tmc water to the Malaprabha river which fulfils the drinking water needs of the twin cities.

Kasaragod, Mar 23: With 19 more positive cases reported on Monday, surveillance against people coming out of their houses and wandering around in public places has been intensified in the district.

With today's addition, the total number of positive cases of Novel Coronavirus (COVID-19) has increased to 38 in Kasaragod.

There will be total restriction in place for the public to step out of their houses. Those who are found outside on the streets would be arrested, caution the district authorities. Please log in to get detailed story.
