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.

Thiruvananthapuram, Jun 9: Malls, restaurants and places of worship opened in Kerala on Tuesday morning after over two-and half months of Coronavirus induced lockdown. There were very few visitors in the malls and restaurants in the early hours and people preferred takeaways in eateries.

Various temples, including the famous Lord Krishna temple at Guruvayoor, a few churches and mosques opened in the state for the devotees. The Guruvayur shrine opened at 9.30 am and around 150 people, who had booked through virtual queue system, offered prayers.

Devotees wearing masks were seen standing adhering to the social distance norm. A faithful at the guruvayur temple said he had booked for darshan on Sunday and was happy to be offering worship after a long gap. "This is a realisation of a dream", he said.

In the state capital while the famed Lord Padmanabha swamy, Pazhavanangadi Ganapathy and Attukal Bhagavathy temples remained shut, the SreekanteshwaraShiva shrine and Lord Hanuman temple near the state assembly were among those which opened for darshan. The names, age and other details of the worshippers are also being collected by the temple authorities before letting people in. Another devotee said it was very painful not to go to the temple and expressed happiness over reopening of the shrines.

The virtual queue booking for devotees to offer worship at the hill shrine of Lord Ayyappa temple at Sabarimala would commence from Wednesday. Devotees from other states have to produce a Covid-19 negative certificate while booking,sources in the Travancore Devaswom Board (TDB), administers the temple, said.

The Ayyappa shrine would open from June 14 to 28 for the five day monthly pooja and temple festival and only 10 people would be allowed inside the shrine at a time, sources said.

Most of the over 1,200 temples under the TDB, have opened while those under the Nair Service Society (NSS), an organisation of the Nair community and few other shrines were shut. The state government, which had come under attack from the BJP and Hindu Aikya vedi for opening the temples in a "hasty manner" has maintained that the decision was taken in line with the Centre's Unlock-1 guidelines and said those opposing the move had earlier wanted devotees to be allowed into the shrines.

As per the centre's Standard Operating Procedures, social distancing should be followed in all the places of worship and devotees should wear face mask are among other precautions in view of the COVID-19 pandemic.

Those above 65 and children below 10 years would not be allowed in places of worship, distribution of food, refreshments and offertory blessings (prasadams), sandalwood paste or ashes should be avoided. Thermal scanners to check body temperatures, sanitiisers, arrangements for washing hands, were all provided in the temples and other places of worship which opened this morning, In churches in the state capital, Kochi and Kozhikode, allowedthe faithful inside after disinfecting the place.

The orthodox church synod is being held on Tuesday which will take a decision on whether or not to open their places of worship. Few mosques were also open in some places.

Among the new cases, three patients from Bengaluru Urban are suffering from Influenza Like Illness (ILI) and another from Severe Acute Respiratory Infection (SARI).

There were seven cases with international travel history to United Arab Emirates (UAE) and one to Turkey.

Meanwhile, 280 people were discharged in the past 24 hours and two persons succumbed to the virus, one from Bidar and another from Vijayapura. Of all the cases, 3,184 are active, 1,968 discharged, 59 dead and 11 in the ICU.

In the past 24 hours, Karnataka tested 11,862 people, of which 11,431 reports returned negative. In total, 3.72 lakh samples have been tested so far, of which 3.61 lakh have returned negative.

Currently, Udupi is leading the state''s Covid-19 burden with 785 active cases, followed by Kalaburagi (448), Yadgir (407), Raichur (320) and Mandya (163) among others.
