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, Feb 3: After neighbouring reported the second confirmed case of dreaded Coronavirus, the government of Karnataka today ordered high alert across border districts including Dakshina Kannada.

Apart from Dakshina Kannada, district administrations in Kodagu, Chamarajanagar and Mysuru that share boundary with Kerala have been put on high alert over the movement of people with suspected cases.

In a statement released on Monday, the Health and Family welfare department said that these districts have been directed to immediately report to the State Surveillance Unit (SSU) if they come across any suspected cases of people infected with Coronavirus.

Currently, about 51 people who returned from Coronavirus-affected regions have been identified and 46 are under home isolation across Karnataka.

So far, 44 samples have been sent to the National Institute of Virology, Pune for analysis and out of which 29 samples have revealed negative results. Yet, the state government has put in all possible measures to check the spread of the virus in any part of the state.

Bengaluru, Jun 18: Real estate continues to be a preferred asset class for investors amid the uncertainty emerging out of the pandemic, according to a report by National Real Estate Development Council (NAREDCO) and Housing.com.

Titled 'Concerned yet positive - The Indian Real Estate Consumer (April-May 2020)', the report showed that the real estate consumer remains positive with regard to the economic scenario and income stability for the coming six months.

"Real estate (35 per cent) is still perceived as the preferred mode of investment, followed by gold (28 per cent), fixed deposits (22 per cent), stocks (16 per cent) and homebuyers are likely to slowly return to the market in the coming six months," it said.

Price-points of residential realty have remained muted for the past few years, but are still a key deterrent, with the perception of being still unaffordable, according to nearly half of the potential homebuyers surveyed, who are currently staying in rented accommodation.

A majority of respondents surveyed (73%) comprise 'first time homebuyers', who are looking to buy a 'ready-to-move-in-house' for end-use and are from the age group of 25-45 years. While 60% of respondents opined that for the next six months, they would prefer a ready-to-move-in property, 21% said they were okay with a property with a delivery timeline of maximum one year.

The survey was conducted in April and May 2020, through a random sampling technique for a fair representation across regions. The insights presented in the survey represent the view of more than 3,000 potential homebuyers.
