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.

Kochi, Jan 22: Rail passengers from Kerala are a happy lot as the state’s traditional food items such as appam and eggcurry, puttu and kadala curry have found their way back to the revised menu of the Railways in the wake of protests over reports that they were replaced by north indian delicacies.

The popular Kerala dishes were reinstated to the list following social media backlash over the Indian Railway Catering and Tourism Corporation’s reported decision to replace the favorite cuisine of Malayalis from its menu with north Indian dishes such as Kachori and Chole Bhature.

Ernakulam MP Hibi Eden, who had shot off a letter to Railway Minister Piyush Goyal raising the issue of alleged discrimination against Keralites, got an assurance from the IRCTC officials that popular items, including snacks such as unniyappam and sukhiyan will be served through its outlets in the state.

Eden said the IRCTC officials who visited him at his home on Wednesday morning have presented him with the list of delicacies to be served by its local vendors in Kerala. In his letter to the minister, the MP had stated that dishes which are very important to Malayalis for breakfast such as appam, egg curry, porotta, dosa, steam cake (puttu) were excluded along with snacks such as banana fry (pazham pori), kozhukkatta, unniyappam, neyyappam and sukhiyan.  He had also raised the issue of hike in price of food items.

According to him, price of meals has been increased from RS 35 to 70 and that ofsnacks such as vada from Rs 8 to 15.  While the price of vada has not been reduced, the fare of snack meal like parotta, chappathi, idiyappam, appam and puttu with kadala curry or egg curry will be served at Rs 50.  According to IRCTC, a passenger will have to shell out Rs 20 for unniyappam/sukhiyan/neyyappam, 2 numbers each.  Informing Goyal of the changes in menu, he said Malayalis are discriminated in trains and railway refreshment rooms by the food which is the right of every passenger.

He had sought urgent intervention of the Minister and speedy action in the matter.
