Kerala CM welcomes Dr Kafeel Khan’s service in Nipah-hit Kozhikode

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, May 19: Officials at the Karnataka State Natural Disaster Monitoring Centre (KSNDMC) said that Dakshina Kannada, Udupi and Uttara Kannada along with Kodagu, Chikkamagaluru have been alerted about possible heavy rains.

Dr GS Srinivasa Reddy, Director, KSNDMC, said, “Coastal districts have already been witnessing heavy downpour since Monday morning. This will continue for another two days depending on the cyclonic movement along the east coast.”

Until last evening, Haleyangadi and Surathkal in Dakshina Kannada district had received 83 mm and 82.5 mm of rainfall, respectively. Several other areas in Udupi also witnessed heavy rainfall of about 60 to 70 mm rainfall.

The India Meteorological Department (IMD) attributed the rain, which intensified on Monday, to a cyclonic circulation over parts of the Arabian Sea (Comorin area) off the coast of Kerala.

The weather department said the sudden convergence of wind over the peninsular region was due to Super Cyclone Amphan, which is set to barrel into the east coast. The IMD issued an Yellow Alert for coastal Karnataka and Malnad, warning of moderate to heavy rainfall in the next few days.

Bengaluru, Apr 20: As many as 59 people were arrested on Monday for attacking police and health officials at the minority dominated Padarayanapura in the city when they went to quarantine some people, police said.

"Fifty-nine people have been arrested (in Padarayanapura) and have been taken into custody. The people attacked the officials who had gone to quarantine some poeple who were the primary and secondary contacts of three COVID-19 patients," a police officer said.

A large number of people, mostly youth from the minority community poured on to the road on Sunday and thrashed the health workers who had gone to quarantine some people who were the primary and secondary contacts of the health workers.

The officials were allegedly beaten black and blue.

Some local residents who went to the rescue of these officials were also thrashed.

According to police, one among the arrested is a woman by name Firoza who had allegedly instigated the mob to attack the health and police officials.

Subsequently, a large number of police personnel were deployed in the area to avert any untoward incident and to quarantine those who are suspected to be infected with COVID- 19.

Blowing sirens, a strong contingent of policemen carried out a flag march in the area.

The Bengaluru police commissioner Bhaskar Rao later called on Chief Minister B S Yediyurappa and briefed him about the situation in Padayarayanapura.

The violent incident drew angry reactions from various quarters.

Karnataka Home Minister Basavaraj Bommai said an incident like the one at Padayarayanapura will not be tolerated.

"I met Chief Minister and briefed him about the incident. He has told us to act strictly. I have told the same to my officials. We won't tolerate such acts by anyone. We have arrested 59 people. Five FIRs have been registered," the minister told reporters.

Bommai, who visited the area took the senior police officials to task for not being present on the spot when the incident took place.

"Where were you? What were you doing when the incident happened?" he questioned a senior police officer.

"We will demonstrate to the people what is containment zone, what is seal down and what is police action," he said.

Condemning the incident, Health Minister B Srimulu warned those who indulged in such activities.

"The inhuman act of attacking police and health workers in Padarayanapura is highly deplorable. Our government will take appropriate step against those indulging in the attack on health officials and police officials who had gone there to protect them," he tweeted.

BJP's firebrand MP Shobha Karandlaje reacted sharply.

"Seculars attack #CoronaWarriors when they were quarantining the secondary contacts of #Covid19 in Padarayanapura of BLR. While #HealthcareHeroes are working overnight to contain #CoronaPandemic, these morons are assaulting our heroes! Let's not be soft on these anti- nationals!" Karandlaje tweeted.

Meanwhile, the minority leaders called on Congress state president D K Shivakumar to persuade the people of the minority community to assist in identifying the COVID-19 patients or carriers.

Former chief minister H D Kumaraswamy too condemned the attack and demanded stringent action against the culprits.

The Congress MLA from the area B Z Zameer Ahmed Khan while condemning the incident, sought to know why the health workers and police officials went to the area late in the night and not in the morning.

"Why did the police and the health workers go in the night when I had told the BBMP Commissioner that I will take them at 10 am?" Khan told reporters.

Defending those who attacked the government officials, Khan said they were uneducated labourers who didn't know what they were doing.

Padarayanapura and Bapuji Nagar were among the first areas to be completely sealed as people were not abiding by the prohibitory orders under Section 144 of the CrPC.
