Mangaluru is a peaceful city; media focusing only on negative things: Top cop

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, June 22: Former Prime Minister Manmohan Singh on Monday asked Prime Minister Narendra Modi to be “mindful of the implication of his words” as a controversy raged over his “no intrusion” remark about the violent face-off with Chinese troops in the Galwan Valley.

“The Prime Minister must always be mindful of the implications of his words and declarations on our Nation’s security as also strategic and territorial interests,” Singh said in a statement here as Chinese media welcomed Modi’s ‘no intrusion’  remarks contending that it may lead to a de-escalation of tensions between China and India.

Congress has been maintaining that Modi’s assertions at Friday’s all-party meeting that neither was there any intrusion nor was any Indian post captured ran counter to the statements made by the Indian Army and the External Affairs Ministry.

Singh said the prime minister cannot allow his words to be used by China as a vindication of its position and all organs of the government should work together to tackle this crisis and prevent it from escalating further.

“We remind the Government that disinformation is no substitute for diplomacy or decisive leadership. The truth cannot be suppressed by having pliant allies spout comforting but false statements,” the former prime minister said.

Singh said the prime minister and the government should rise to the occasion to ensure justice for Colonel B Santosh and the army jawans who made the supreme sacrifice and resolutely defended the nation’s territorial integrity.

“To do any less would be a historic betrayal of the people’s faith,” the former prime minister said.

“At this moment, we stand at historic crossroads. Our Government’s decisions and actions will have serious bearings on how the future generations perceive us,” Singh said.

Singh said China was brazenly and illegally seeking to claim parts of Indian territory such as the Galwan Valley and the Pangong Tso Lake by committing multiple incursions between April 2020 till date.  

“We cannot and will not be cowed down by threats and intimidation nor permit a compromise with our territorial integrity,” said Singh. 

The former prime minister said this was a moment where “we must stand together as a nation and be united in our response to this brazen threat.”

Mangaluru, July 23: Lavanya Ballal, national co-coordinator for social media department of Indian National Congress, has accused the Bharatiya Janata Party of destroying the nation by misleading the youth.

In an interview with a regional Kannada news paper, the Dakshina Kannada based activist, lamented that instead of using social media for the welfare of the nation, BJP leaders used it to spread lies for their political gains. 

On one hand BJP fooled people through false promises and colourful dialogues, while on the other hand it misled crores of youth by spreading fake news, twisted facts and false information, she said.

Ms Ballal went on to accuse BJP of following the footsteps of the British. “BJP is following all the methods employed by the British invaders to divide the people of India and make them hate each other,” she said.

She said that Congress always used the social media for the benefit of the country. If the new generation realises this fact, the country will once again turn its direction towards development, she asserted.
