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, Jun 10: Internet connectivity, provided under the central government's BharatNet initiative, will be improved in rural areas of Karnataka in the next two to three months, said Deputy Chief Minister CN Ashwath Narayan.

After video conferencing with heads of different agencies and officials, on improving the quality of internet in rural areas, Ashwath Narayan said, "I reviewed the progress of the BharatNet implementation and the steps to be taken to improve the quality of internet connectivity in the next two to three months."

"We also discussed the possibility of giving the implementation of BharatNet to a different agency. We will seek permission from the central government and continue the project. We will ease communication with rural people by ensuring quality and high-speed internet to all Gram Panchayats," he added.

When BSNL officials and other agency representatives who attended the video conference shared their problems, the Deputy Chief Minister assured to solve them through proper coordination.

"Through BharatNet, several government schemes are being implemented in rural areas. Civic service centres are issuing birth and death certificates, Aadhaar cards and social security pensions among others. Of the total 6,000 Gram Panchayats in the state, 4,000 have high-speed internet connectivity, and the remaining will be provided with better internet connectivity through a new agency,'' said Ashwath Narayan.

Additional Secretary (e-governance) Rajeev Chawla, Additional Chief Secretary (IT-BT) EV Ramana Reddy, Principal Secretary (RDPR) Uma Mahadevan, Director (IT) Meena Nagaraj, Collegiate Education Director Pradeep and other senior officials were present in the meeting.

Bengaluru, Jul 3: The Karnataka government is allowing select asymptomatic and mildly symptomatic Covid-19 patients to recuperate at home as part of home isolation guidelines, an official said on Friday.

"Only those who are asymptomatic or mildly symptomatic shall be allowed to be in isolation at home," said a health official, highlighting that such patients should be properly oriented on home isolation.

However, before home isolation, a health team will visit the patient's house and assess its suitability for executing home isolation.

Similarly, the patient should be provided with a tele-consultation link for initial triage, daily follow up and during the entire home isolation time.

For a daily update, the patient isolated at home should give a report on his health status to the physician or health authorities.

"The home isolation shall be with the knowledge of the family members, neighbours, treating physician and local health authorities," said the official.

Though home isolation is allowed, it is not a blanket permission for all asymptomatic and mildly symptomatic cases in Karnataka to avail.

"Such cases should have the requisite facility at their residence for self-isolation and also for quarantining the family contacts. A care giver should be available to provide care on 24x7 basis," said the official.

Likewise, the caregiver should also have a regular communication link between him and the hospital during the home isolation.

No patient above 50 years will be allowed to avail home isolation.

"If the patient has the following comorbidities: hypertension, diabetes, obesity, thyroid disease, they shall be well managed and under good clinical control as assessed by medical officer," he said.

However, patients with comorbidities such as kidney diseases, dialysis, heart diseases, stroke, tuberculosis, cancer and HIV cannot avail home isolation.

Likewise, immunity compromised patients and those on steroids also cannot be on home isolation.

Though pregnant women are not allowed to avail this facility, lactating women are allowed after due instruction and assessment.

The Health Department has also issued several other guidelines and protocols for a patient choosing home isolation.
