8-year-old girl saves 2-year-old brother from ‘holy cow’; video goes viral

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, Jul 9: Alarmed over surging COVID-19 cases, the Karnataka government has decided to divide this tech city into containment zones to curb the spread of the pandemic, a state minister said on Thursday.

"The city will be divided into red, orange and yellow zones in commensurate with the number of Covid cases in them for containing the virus spread on war footing," Law and Parliamentary Affairs Minister J.C. Madhuswamy told reporters here.

Cabinet ministers representing assembly segments in the city will be in-charge of the zones to ensure the cases are curbed with strict enforcement of lockdown guidelines, especially wearing mask and maintaining social distancing by the people in the confinement areas.

"Chief Minister B.S. Yediyurappa has convened a meeting of ministers, MLAs, MPs and corporators of all the 198 civic wards across the city on Friday to discuss and draw an action plan to contain the pandemic," said Madhuswamy.

With 1,148 positive cases, the city''s Covid tally rose to 12,509 and active to 10,103, while 2,228 were discharged, including 418 on Wednesday, while 177 succumbed to the infection since March 9, with 23 in the last 24 hours.

"The Chief Minister ordered deploying more ambulances in the containment areas where cases have been spiking daily to rush Covid patients to the nearest hospital for immediate treatment," said Madhuswamy.

The city civic corporation -- Bruhat Bengaluru Mahanagara Palike (BBMP) --has increased the containment zones to 3,181 due to more cases spiking, with southern and western suburbs accounting for most infections.

"The containment zones are concentrated more in the city''s southern and western suburbs. Active cases doubled over the last 8 days and shot up to a whopping 12,509 from 4,555 on June 30," an official said.

Refuting graft charges by opposition Congress leader Siddaramaiah in the purchase of medical equipment for treatment of Covid patients, Madhuswamy said the state government had not spent more than Rs 600 crore so far.

"We are running a government. Not a private office. We will give account. He (Siddaramaiah) is welcome to check the accounts and verify the documents," asserted the minister.

In a related development, the cabinet also approved an ordinance to increase the state contingency fund to Rs 500 crore from Rs 80 crore for the Covid-19 induced economic relief measures announced by the chief minister in June.

Mangaluru/Udupi, Mar 23: The coastal district of Dakshina Kannada including the city of Mangaluru today refused to return to normalcy from yesterday’s Janata Curfew, as the government imposed lockdown in the district till the month end to contain the Covid-19 caused by the deadly novel coronavirus.

The lockdown coupled with the prohibitory orders under Section 144 has forced all the commercial establishments barring few to remain closed in the district.

The police started issuing stern warning to the people through loudspeakers against venturing out of their homes unnecessarily. People are allowed to move only in case of any emergency or basic needs.

The police warning came after a few people started ignoring the lockdown and ban orders. A few private buses also were seen plying on the roads in the morning.

Under the proibitory orders, the district administration banned from venturing out of their homes except in case of emergency or extreme necessity. All public programmes including religious ceremonies, cultural programmes also are banned. All shops, commercial establishments, workshops and godowns with other unessential goods are supposed to remain closed. Bus service, both government and private, are to suspended. Mass prayers and religious ceremonies are not allowed in temples, mosques and churches. Beaches and other tourist spots are closed.

Udupi

The lockdown in 9 districts of Karnataka has forced many private buses in Udupi to stay off the roads for second day on Monday. Some buses plying between Udupi to Kundapur have resumed service a day after Janata Curfew, with very minimum occupancy.

Due to lockdown in Dakshina Kannada, all services operating from Mangaluru to Udupi, Manipal, and Kundapur have been suspended till the month end. Buses on Karkala-Udupi route have also stopped their operations.
