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.

A motley group of as many as 150 birders ‘walked the chirp’ in search of their feathered friends in and around the countryside of Manipal. The occasion was the 10th Edition of Manipal Bird Day organised by Manipal Birders Group on Sunday, February 2nd, 2020.

The day began ‘Bird Walk’ from Hotel Sheela Sagar (Opposite MIT campus) at 6:30 a.m. The birders divided themselves in smaller groups of 10-12 members and followed 13 different trails which took them through different terrains like hills, plains, paddy fields and wetlands. The idea was to sight as many birds as possible and record their presence in the region.

When the walk ended at about 10:00 a.m., the different groups have recorded a total of 125 species of birds, which was a bit lesser than the sighting of the yester years. “The 10th edition this year has seen a very good growth of interest among people. At the same time a decline has been seen in the bird species sighted compared to previous years,” said one of the organisers. Some of the rare birds sighted were Indian Pitta, Oriental Turtle Dove, Fork-Tailed Drongo Cuckoo, Orange Breasted Green Pigeon, Eurasian Marsh Harrier and Malabar Pied Hornbill.

The bird walk was followed with an interaction session at KMC Food Court and MAHE Vice Chancellor Dr. H. Vinod Bhat presided over the function. He felicitated six people who actively participated recently in a rescue mission of abandoned birds in Manipal.

A program then continued with a talk on ‘Ethical Photography’ by Dhruvam Desai, final year student of MIT, Manipal. This was followed by ‘Backyard Birding’ with Shubha Bhat from IISc Bangalore. She spoke on different ways to feed the birds with water using different materials for bird baths. “I have recorded 120 species of birds from bird baths in my garden,” she said. She encouraged the participants to have bird baths in their gardens or flats which will help quench the thirst of these little winged wonders during summer.

The participants involved themselves actively in the interaction sessions. The event was accompanied with an art exhibition titled ‘Feathered Jewels’ by Aditya Bhat. He presented around 18 paintings all from his memory of birding encounters.

Participation in Manipal Bird Day was open to all and entry was free.

MANIPAL BIRD DAY

Manipal Bird Day is an annual event dedicated to celebrating birds in Manipal. This day long event brings together a large number of birders from Manipal, Udupi, Mangalore, Mysore, Bangalore, Davangere and other places. Around 150-200 people gather and are split into different teams. They visit the assigned regions and count as many birds as possible. This non competitive event focuses on spreading awareness regarding the diverse avifauna around us. Turn out for this event has been increasing from 3 people to 200 in last 10 years. This is the 10th edition of Manipal Bird Day.

MANIPAL BIRDERS CLUB

Manipal Birders Club started as a Facebook group after the release of the first edition of “A Birders Handbook to Manipal” to share information about the latest sightings. It is now a formal group of over 500 like-minded members that meets at least once a week to go on bird walks. It is now a large birders community and a medium to organize events, bird walks and discussions about birds and sightings.

The next step would be to involve a higher number of local and young birders who will dictate the change in environment around the town in the coming years. With the co operation of Zoology and natural sciences students and other nature enthusiasts and faculty of different colleges weekly birding sessions have been conducted to involve and encourage more and more people to bird and get connected to the nature and to try to understand the changes happening around us, the media release issued by the group said.
