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, Feb 16: Radhakrishnan V Nair embarked on a journey of exploring complex subjects and opening up the cocoon of existence that puts people in a zone of comfort. One sole mission of the book is to encourage the readers to break out of that comfort zone.

The architect by profession has a novel to his credit, 'The Cave of Freedom' that had earned him critical acclaim from Jnanpith Awardee UR Ananthamurthy. On February 13, a discussion and the reading of his book had the audience riveted to their seats.

The launch of the book on February 13 at Bangalore International Centre was presided over by Bhaskar Rao, Commissioner of Police, Bengaluru, along with Vasudev Murthy, Technology Management Consultant, leadership trainer and author and Ramessh RK, an industrial designer and choir singer who read out passages from the book.

'Radhakrishnan is trying to inspire you to discover the pleasure of breaking the glass barrier along with the protagonist Dr Prateek. The story 'burst out'", said Radhakrishnan when it could not be contained any longer.

The glass ceiling saw a lot of interest from the audience present. The book includes Dr Prateek who is obsessed with saving lives in the Emergency Room (ER) as the world slept. Then on an eerie rainy night, he is kidnapped.

He struggles to come to terms with the improbability of waking up somewhere in Europe and making his serendipitous escape and being back at work the next morning - all physically impossible from the point of view of time and locality.

The glass ceiling challenges you to see tragedies and their impact on a person's mental well-being from a different perspective.

Radhakrishnan V Nair is an architect by profession and runs his Bengaluru-based firm - Archaid, the tagline of which is 'Architecture in Collaboration with Nature'.

New Delhi, Jan 9: Crime in India has increased by 1.3 per cent in 2018 compared to 2017 with the registration of over 50 lakh cognisable crimes, reveals 2018 edition of 'Crime in India' statistics released this week by the National Crime Records Bureau (NCRB).

No let up in road accident deaths in 2018: NCRB

There were 1,35,051 incidences of deaths due to negligence relating to road accidents in 2018, according to the latest NCRB report on "Crime in India -2018".

When compared to the previous two years, the statistics show that there has been no significant change in the overall situation.

In 2017 there were 1,34,803 incidences reported from across the country, while in 2016 it was 1,35,656.

Incidents of 'Hit and run' accident cases have climbed up marginally over the last year, if the latest figures are any indication. In 2018, the 'hit and run' cases reported were 47,028. In 2017, the cases registered under this category were 43,727.

The data collection process for NCRB report on "Crime in India - 2018" including clarifications from the states/UTs/central agencies started in July, 2019 and continued till December, 2019.

People involved in farming sector, including 5,763 farmers or cultivators, committed suicide during 2018, the report reveals.

The annual data was released around three months after the government released the National Crime Records Bureau (NCRB) report on "Crime in India 2017".

As per the latest data, of the 10,349 persons who committed suicide in 2018, 4,586 were agricultural labourers.

The number of suicides in farming sector in 2018 accounts for 7.7 per cent of the total suicide victims (1,34,516) in the country, the NCRB data said.

Suicides in India in 2018 rose to 1,34,516 from 1,29,887 in 2017. Rate of suicides is also up from 9.9 in 2017 to 10.2 in 2018.

In 2017, a total of 10,655 farmer suicides were reported.

West Bengal, Bihar, Odisha, Uttarakhand, Meghalaya, Goa, Chandigarh, Daman and Diu, Delhi, Lakshadweep and Puducherry reported zero suicides of farmers or cultivators and agricultural labourers during 2018, said the report.
