Lies and propaganda galore after abrogation of Article 370

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, May 5: Karnataka Chief Minister BS Yediyurappa on Tuesday said that the coronavirus situation in the state is "under control" as compared to several other states in the country.

He also hinted that soon the construction and industrial activities would be allowed in the state except in the red zones.

"Coronavirus situation in the state is under control as compared to other states. Due to this, travel of migrant workers was prohibited. Now, trade, construction and industrial activities need to restart, except in the red zones," he told reporters.

According to the Karnataka Health Department, the state has so far recorded 659 COVID-19 cases, including 324 discharged and 28 deaths.

Bengaluru, Jan 23: An alleged low-intensity blast on Wednesday late evening in Shanthinagar left three-time Congress MLA NA Harris and six others with burn injuries. The blast reported at around 8:30 pm during a cultural programme gripped the central parts of Bengaluru in a panic especially after the incident of police recovering a live bomb in Mangaluru airport. 

According to sources in Shanthinagar, MLA Harris was attending the birthday celebrations of MGR organized by the locals close to his residence in Shanthinagar. Following the blast, Harris and a few others who standing close to the MLA sustained burn injuries and rushed to the nearby Philomena Hospital immediately and police officials from both the Ashok Nagar and Vivek Nagar visited the spot. The police officials are yet to confirm whether it was a bomb blast or due to the bursting of loud and powerful crackers. 

Chethan Singh Rathore, DCP (Central) visited the hospital and the blast site. A team of forensic science lab experts have also been summoned to the spot to collect samples for ascertaining the nature of the blast. MLA Harris’s son Mohammed Nalapad who rushed to the hospital along with supporters told media persons that they are completely shocked by the incident. 

“He was sitting on a chair and suddenly something that was hurled at him exploded beneath the chair. He sustained injuries to his leg and brought to the hospital. He is being treated by a team of doctors and other injured supporters are also being attended to by the doctors,” Nalapad said. 

Expressing shock over the incident, he said, “My father has been an MLA for 12-years and nothing of this sort had happened before in the constituency. We have no rivals and my father never had any gunmen. We are all shocked and have complained to the jurisdictional police.” 

Meantime, Dr Shankar Prasad, Medical Director, St Philomena’s Hospital explained that Harris and others are currently being treated for minor injuries. “None of them have any open cut injuries and they are being examined further,” Dr Prasad told DH. 

According to Dr Prasad, Harris had a minor blood clot in his left leg which was possibly due to a hard object hitting him during the blast. “We have taken X-Ray and examining further. At the look of it, it seems like a very minor injury,” he added.
