Bloodshed continues in Bantwal taluk: SDPI activist brutally hacked to death

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.

Mangaluru, Jan 26: Minister for Muzrai, Inland Water Transport, Port and Fisheries Kota Srinivas Poojary in his Republic Day address praised the Dakshina Kannada district and Mangaluru city units of Karnataka police.

Poojary, also district in-charge minister, was speaking after unfurling the National flag as a part of 71st Republic Day celebrations held at Nehru Maidan in the city on Sunday.

He said that the police department had been successful in tackling the challenges posed by anti-social elements to the law and order situation from time to time.

He also lauded the police department for effectively handling the recent bomb threat incident at Mangalore International Airport.

He said, the state government is committed to protect the welfare of the oppressed and backward classes, minority, women, farmers, differently abled and the elderly.

“People from all these sections are guaranteed government benefits in one way or the other,’’ the minister said and called upon the people to strive towards social harmony and to help the departments concerned in keeping anti-social elements away.

The state government will release its share of Rs 4,000 to the farmers under Pradhan Mantri Kisan Samman Yojana, to which Central government has credited Rs 6,000 per eligible farmer. As many as 1,33,247 farmers are benefited by the scheme in the district, the minister said.

Stating that the coastal region of Karnataka has been placed in the ninth position in the country in fisheries, Poojary said that the coastal line of Karnataka, comprising backwaters and inland water, houses immense resource for fishes.

“Thrust will be laid on boat tourism and development of ports in the coastal districts,’’ he said.

The minister, meanwhile, said that the state government had implemented various programmes for the development of fishermen community.

“Loans to the tune of Rs 60.54 crore availed by 23,000 women belonging to fishing community will be waived. Diesel subsidies amounting to Rs 28.09 crore has been transferred to the bank accounts of owners of 954 mechanized boats during the year 2019-20. As many as 2,500 houses have been sanctioned under Matsyashraya scheme,’’ Poojary said.

Dakshina Kannada district has incurred a loss of Rs 893 crore during the recent floods. Financial assistance has been extended to 1,914 families affected by the floods to buy essential commodities, he said.

Services recognised

The minister thanked the Central government for announcing Padma Vibhushan awards to late Vishwesha Theertha Swami and George Fernandez and Padma Shri award to Harekala Hajabba.

‘’The selfless services to the nation by these stalwarts have been recognised,’’ he said. Educationist Harekala Hajabba was felicitated on the occasion.

Zilla Panchayat President Meenakshi Shanthigodu, MLAs D Vedavyas Kamath, Dr Y Bharat Shetty and U T Khader, MLCs Ivan D’Souza and S L Bhoje Gowda were present. Various troupes conducted march past on the occasion. Schoolchildren took part in cultural programmes.
