Tigers are like terrorists; make cow ‘national animal’ to end terrorism: Pejavar Seer

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, Mar 6: All the arrested in a case of sedition filed over a school play in Karnataka's Bidar have been granted anticipatory bail by a court that said the case lacked enough basis.

The play, themed on protests against the Citizenship (Amendment) Act (CAA), "has not caused any disharmony in the society", said the district and sessions court in Bidar.

The play, performed in January by the children of prestigious Shaheen School, landed in trouble when a sedition complaint was filed over an 11-year-old girl's lines - enacting an elderly woman, she said if anyone asked for documents she would hit them with slippers.

That led to a sedition case and the police questioning children, teachers and the school management over many rounds.

"The drama has not caused any disharmony in the society. Considering all the circumstances, I am of the opinion that the ingredients of Section 124A of IPC (Sedition) are prima facie lacking," said the court.

Five members of the school management team have been granted protection from arrest. Earlier, the head teacher and the mother of the student who spoke the dialogue were sent to custody, but on other charges including the abetment of an offence. They were not accused of sedition. They were later granted bail.

The repeated questioning of young students and the arrest of the widowed mother of a student caused a huge uproar in the town.

An order is expected soon on the bail application in another sedition case in Karnataka, against three Kashmiri students. The students, who were studying in Hubbali in north Karnataka, are facing charges for reportedly using pro-Pakistani slogans in an online post. The Hubbali Bar Association had asked its members not to represent the students. Lawyers from Bengaluru who went to Hubbali represent the students were heckled.

On Thursday, a team of lawyers from different districts again went to Hubballi and were provided police protection. BT Venkatesh, one of the lawyers, said he had a meeting with bar association members and that the matter was sorted out. The students have applied for bail and an order is expected next week.

Mangaluru, Apr 19: The covid-19 being spread by the novel coronavirus has claimed a life in the coastal district of Dakshina Kannada.  

The victim, a 50-year-old woman from Bantwal taluk, breathed her last at Wenlock Hospital today morning. 

She was rushed to a private hospital yesterday after she developed breathing problems. Then she was shifted to Wenlock Hospital's block for suspected coronavirus patients, and placed in the intensive care unit (ICU).

Her throat swab was collected the same day and sent for testing for coronavirus. However, today morning her condition worsened and she passed away.

The report was received on later on Sunday afternoon, which confirmed that she had contracted coronavirus.

The woman's family members including her husband, son and mother-in-law have been placed under quarantine. It is learnt that her mother-in-law's condition is serious and she has been admitted to the ICU.

The throat swabs of all the three family members have been sent for coronavirus test. According to sources, the woman's son had come from Dubai recently.

Meanwhile, a 30-year-old woman from Uppinangady, who is undergoing treatment in a hospital, today tested positive for the covid-19.

With the confirmation of two new cases, the total number of reported covid-19 cases in Dakshina Kannada reached 15. Out of which only two case are currently active and 12 have been discharged. Another one passed away.
