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.

Mumbai, Jul 11: Bollywood veteran Amitabh Bachchan announced on Twitter late on Saturday that he tested positive for the novel coronavirus infection.

Taking to Twitter to announce the news, he said, "I have tested CoVID positive... " He added that family and staff had also undergone tests while Bachchan has been shifted to a hospital. 

Bachchan ended his tweet saying, "All that have been in close proximity to me in the last 10 days are requested to please get themselves tested !"

T 3590 -I have tested CoviD positive .. shifted to Hospital .. hospital informing authorities .. family and staff undergone tests , results awaited ..

Bengaluru, May 17: Karnataka Deputy Chief Minister and Transport Minister Laxman Savadi on Sunday wrote to Union Minister Nitin Gadkari requesting to issue new lockdown guidelines including permission to operate public transport and said the lockdown has caused a financial loss of Rs 16,00 crore to all four Karnataka Transport Undertakings.

In view of these problems, the state Transport Minister requested Gadkari to permit the deployment of Non-AC buses on scheduled routes to ensure the adequacy of services.

The four State Transport Undertakings (STUs) in Karnataka which are providing bus-based public transport services within the state and to the neighbouring states are Karnataka State Road Transport Corporation (KSRTC), North West Karnataka Road Transport Corporation (NWKRTC), North Eastern Karnataka Road Transport Corporation (NEKRTC) and Bangalore Metropolitan Transport Corporation (BMTC).

"KSRTC, NWKRTC and NEKRTC operate buses for mofussil services i.e. Interdistrict, intradistrict and interstate, whereas BMTC operates only in urban and suburban areas in the city of Bengaluru. The four STUs put together hold a fleet of about 24,900 buses including 1,520 air-conditioned buses and operate about 71.00 lakh km. per day and carries about 98.00 lakh passengers every single day," Savadi outlined in the letter.

The Minister said due to the COVID-19 outbreak and the lockdown that ensued have brought regular bus operations and functioning to a grinding halt.

"This has caused a devastating impact on the operations of all the four STUs due to the combination of lack of revenue and continuing fixed costs such as salaries and pensions to staff, payables against existing loans etc. It has been estimated that the lockdown has caused a financial loss of INR 1,600/- crore to these four STUs," he added.

Savadi said even after post-COVID lockdown, operations and revenues won't reach its previous demand& supply patterns in the next six to eight months due to reduced economic activity and users' perceived risk of contacting COVID in public transport.

In addition to that, "occupancy should be allowed up to seating capacity (without standees). This is essential to meet minimal demand," he said in the letter.

"The crew should wear facemask and hand gloves. The crew with health issues should not be deployed. The face masks should be made mandatory for all the passengers. Only asymptomatic persons should be allowed to travel in public transport. The Government of India may consider staggering working hours for various sectors to reduce peak hour traffic demand," the minister listed out these recommendations in the letter.

Savadi said that with social distancing norm of reduced seating capacity in public transport, it will not be possible to provide transport facility to all the daily passengers. This will create demand for more buses, which cannot be met.

"Restrictions on public transport will lead to passenger commute by overcrowding in smaller vehicles like cars, maxi cabs, goods tempos etc. which will adversely affect preventive measures," he added.

Therefore, Savadi requested Union Minister to look into the above matter and issue fresh guidelines to all the states / UT's.
