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, Apr 19: A recent government order prohibiting congregations, Ramadan prayers is discriminatory and needs to be withdrawn, JD(S) MLC B M Farookh has demanded.

In a letter to the chief secretary, Farookh pointed out that the order contained certain conditions such as restriction of the use of public address system and delivering Azan in low decibels, which had nothing to do with the prevention of Covid-19 disease.

“These days, Azan includes a call for the community to pray at home and does not offer namaz at mosque. The order also prohibits preparation and distribution of porridge, which has always been taken up in the interest of the poor. The High Court has noted that the relief distribution by NGOs or individuals should not be prevented and the state machinery has to coordinate the same by ensuring social distancing. The ban on distribution of porridge by mosques amounts to discrimination. The order needs to be withdrawn or revisited,” he wrote in his letter.

Further, observing that a religious fair was conducted in Kalaburagi recently, in violation of the government’s social distancing norms, Farookh sought the government to ensure that social distancing norms are enforced with regard to festivals of all communities without discrimination.

Bengaluru, Jan 21: Controversial Mysuru ruler Tipu Sultan will remain in state-syllabus textbooks in the next academic year (2020-21) too. But the government will form another committee to look at the subject afresh.

"Efforts are on to give textbooks and uniforms the day schools open next academic year. After a discussion with the CM, we decided to not make any changes in the textbooks for the upcoming academic year,"said primary and secondary education minister S Suresh Kumar.

No political angle, says minister

However, we will form a committee to look into it again,” said the minister.

Three months ago, Madikeri MLA Appachu Ranjan had written to the minister seeking removal of contents on Tipu Sultan from Karnataka state syllabus books of classes 6,7 and 10. The minister said: “Appachu Ranjan is a five-time MLA. When he sent a letter, it’s my duty to seek an opinion on it. There’s no political angle here.”
