'If Hindu, then why promote eating beef?' Yogi asks Siddaramaiah

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 17: Amidst mounting demand form Kannadigas across the world for repatriation flights in the wake of covid-19 lockdown, Dr Arathi Krishna, former Deputy Chairman of the NRI Forum of Karnataka government, has written to Hardeep Singh Puri Minister of Civil Aviation to operate more special flights to Gulf repatriate Kannadigas from gulf countries. 

Dr Arathi Krishna’s first request in the letter was to add flights from Kuwait, Bahrain and Jeddah to Bengaluru as many (from Karnataka) are stranded in these cities in precarious situations.

In addition, she also requested for a couple of flights from Dammam and Riyadh to Bengaluru as there are more than 3780 Kannadigas registered to return from Saudi Arabia and members of Bearys Chamber of Commerce and Industry are requesting the same. Any number of flights from Dubai to Bengaluru and Mangaluru will also help the stranded people, the letter stated. 

“Old and sick people, pregnant women and others are in urgent need to connect with the world are looking up to you for getting flights from different comers of the world. Indian communities are hopeful that you will use your position to help them to get the much needed mobility at this time,” the letter stated. 

She also said that the people in Karnataka are grateful to you (Mr Hardeep Singh Puri) for adding two flights from Dubai to Bengaluru in the last two schedules and one flight each from Riyadh, Dammam, Muscat and Doha.

Dr Arathi Krishna is currently serving as the Chairman of the NRI Cell of Karnataka Pradesh Congress Committee and Secretary of Indian Overseas Congress.

Bengaluru, Jan 18: The searches by income-tax officials at the residence of south Indian actress Rashmika Mandanna at Virajpet in Kodagu district were concluded on Friday.

The searches, conducted since Thursday by sleuths from Bengaluru, were concluded on Friday morning, the family said.

Speaking to reporters outside the house, the actress's mother Suman said: "We all cooperated with the officials since Thursday. The officials asked some questions which we answered properly."

Rashmika, who was not at the residence when the I-T officials arrived, joined them on Thursday night, she added.

According to sources, IT officials from Bengaluru who arrived in three cars on Thursday verified documents pertaining to properties, bank accounts and investments.

Rashmika has acted in several Kannada and Telugu movies. Her recent film 'Sarileru Neekevvaru' opposite popular Telugu actor Mahesh Babu is in the theatres now.
