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, Jan 21: Karnataka Chief Minister's political adviser MP Renukacharya has courted controversy yet again with his remarks targeting the Muslim community at a pro-CAA rally in Karnataka on Monday.

Addressing a rally in support of the new citizenship law, the BJP lawmaker accused Muslims of collecting weapons in mosques instead of praying. "There are few traitors who sit in a masjid and write fatwas. They collect weapons inside the mosque instead of praying. Is this why you want a Masjid," Renukacharya said on Monday.

Renukacharya said he won't hesitate to use the money allotted to Muslims for Hindus. "I will resort to such politics in my taluk where the money allotted for Muslims can be used for Hindus. I will put you [Muslims] in your place and show what politics is," said Renukacharya, who is a close aide of CM BS Yediyurappa.

This is not the first time a Karnataka BJP leader has made communal remarks targeting the minority community. Earlier, BJP MLA Somashekar Reddy had made controversial remarks at a pro-citizenship law protest in Ballari when he asked those opposing the Citizenship (Amendment) Act to think of the "consequences" if the majority community members hit the streets against them.

The MLA had said, "If you do any drama, then if 100 per cent people come, understand what will be your situation. Congress people are lying to you, believing them you are coming on streets. We are 80 per cent, you are 17 per cent, if we react, what will be your situation? Be careful," Reddy had said.

Following outrage, a case was filed against Somashekar Reddy for alleged provocative speech targeting those protesting against the amended citizenship law.

Bengaluru, May 11: Karnataka Medical Education Minister Dr K Sudhakar today held a video conference with Kerala Health Minister KK Shailaja to discuss measures to tackle COVID-19.

The ministers discussed in detail the protocols for testing, quarantine and treatment for COVID-19 that are being followed by both the states.

The Karnataka Health Department on Monday said that 10 new cases of COVID-19 have been reported in the state, taking the total number of positive cases to 858.

"31 people have lost their lives due to coronavirus in the state and 422 persons have been discharged after recovery," the Health Department added.

Kerala, on the other hand, has tackled the coronavirus crisis better than most other states of the country. There are only 19 active cases of COVID-19 in the state while 489 people have recovered. The death toll in the state is 4, according to the data published by the Union Ministry of Health and Family Welfare on Monday.
