Man held for throwing stones on bus for ‘time-pass’

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.

New Delhi, Mar 6: The Supreme Court on Friday refused to entertain a plea seeking framing of a proper mechanism to deal with alleged misuse of the sedition law by the government machinery. A bench headed by Justice A M Khanwilkar dismissed the plea filed by a social activist and said it was open for the petitioner to approach the appropriate authority.

At the outset, the apex court told advocate Utsav Singh Bains, appearing for the petitioner, that he could not seek quashing of an FIR in a sedition case filed against the management of a Karnataka school for allegedly allowing students to stage an anti-CAA and anti-NRC drama.

Bains told the bench that he was not just pressing for a prayer to quash the FIR but the petitioner has also sought a direction for framing of a proper mechanism to deal with the alleged misuse of the sedition law.

"Let the affected party come and we will hear them. Why it should be done at your instance," the bench said, refusing to entertain the petition.

The petition had sought quashing of the FIR against the principal and other staff of the Shaheen School at Bidar who have been booked under sections 124A (sedition) and 153A (promoting enmity between different groups) of the Indian Penal Code.

The plea had also sought an apex court direction for a proper mechanism to deal with alleged government misuse of the sedition law.

Section 124A of the IPC says that "whoever brings or attempts to bring into hatred or contempt, or excites or attempts to excite disaffection towards... the Government shall be punished with imprisonment for life...".

The plea had sought a direction to the Centre and the Karnataka government "to quash the FIR registered in connection of seditious charges against the school management, teacher and a widowed parent of a student for staging a play criticising CAA, NRC and NPR."

The petition had claimed that the police "also questioned students, and videos and screenshots of CCTV footage showing them speaking to the students were shared widely on social media, prompting criticism."

The drama was staged on January 21 by students of the fourth, the fifth and the sixth standard.

The sedition case was filed based on a complaint by social worker Neelesh Rakshyal on 26 January.

The complainant alleged that the school authorities "used" the students to perform a drama where they "abused" Modi in the context of the Citizenship (Amendment) Act and the National Register of Citizens.

Udupi, May 19: Within minutes after health and family welfare department announced four fresh covid-19 cases in Udupi district, a girl who had come from central part of Karnataka tested positive for the coronavirus thereby taking the count of cases detected after last evening to five. 

With this the total number of confirmed covid-19 cases in the district rose to 16. Three among them have recovered. One patient died last week. There are 12 active cases. 

According to sources, the 17-year-old girl from Chitradurga had visited KMC hospital in Manipal for cancer treatment on May 16.
