Massive fire breaks out at Abu Dhabi Marina Yacht Club

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.

Kasaragod, Feb 17: A Kerala Muslim couple conducted the wedding of their Hindu foster daughter at a Bhagavathi temple in Kerala, scripting another tale of communal harmony at Kasaragod.

The wedding ceremony was held on Sunday.

The woman Rajeshwari tied the knot with Vishnu Prasad in the presence of family and friends belonging to both Hindu and Muslim communities.

Abdulla and Khadeeja adopted Rajeshwari after her father who worked at Abdulla's farm died. Rajeshwari's mother also passed away when she was a child.

Rajeshwari grew up alongside Abdulla and Khadeeja's three sons- Shameem, Najeeb and Shereef.

Earlier in January this year, cutting across the lines of religion, a mosque in Kerala's Kayamkulam hosted a Hindu marriage ceremony.

Bengaluru, Jan 6: Karnataka Chief Minister BS Yediyurappa on Sunday launched the ruling BJP's outreach campaign in favour of the Citizenship Amendment Act (CAA) in Bengaluru.

"The CAA came into being after its amendment bill was passed in Parliament during its winter session with the support of major political parties. It is meant to give shelter and protection to Hindu minorities facing persecution in Pakistan, Bangladesh and Afghanistan. It does not take away any rights of Indians," Yediyurappa told residents on a door-to-door campaign in the city.

Accusing the opposition Congress of misleading the people on the CAA and inciting its protesters to indulge in violence, the chief minister said the Act does not cause any problem to all sections of Indians.

"There is no question of taking away anyone's citizenship, including that of Muslims, as the Act only facilitates the return of the Hindus persecuted in the neighbouring countries in the sub-continent," he asserted.

State deputy chief minister H.C. Ashwath Narayana and party's Bengaluru Central Lok Sabha member P.C. Mohan accompanied the chief minister on his outreach programme in some residential and commercial areas of the city.

As part of the nationwide campaign in favour the CAA, the party's state unit president Nalin Kumar Kateel and the state's dozen cabinet ministers led the campaign in other cities across the southern state.

"An awareness campaign will be peacefully held daily till January 15 across the state to counter the protests against it by students and other people at the behest of the Congress and Left parties," Kateel told reporters at Mangaluru, 350km southwest of Bengaluru.

Kateel is a BJP Lok Sabha member from the state's Dakshina Kannada seat.

Besides contacting the people directly at their doorstep through the party's leaders, cadres and supporters, the BJP is reaching all sections of society through social media and by holding pro-CAA rallies in all the 30-district headquarters across the state over the next 10 days.

"About 300 leaders and cadres of the party have fanned out in cities and towns across the state to explain the provisions of the CAA to the people and clarify their doubts, as the protesters were misleading them with wrong information about it," reiterated Kateel.

The CAA came into being after the President enacted the a law to give citizenship rights to Hindus, Sikhs, Jains, Parsis and Christians who have been allegedly persecuted as minorities in Afghanistan, Bangladesh and Pakistan over the last seven decades.

"A deliberate misinformation campaign has been carried out against the CAA by vested interests, misguiding a section of college/university students, their faculty, activists and members of the minority community on its provisions so as to create unrest and trigger violence in the country," Ravikumar claimed.

The ruling party also held rallies and public meetings in major cities like Mysuru, Mangaluru, Hubballi, Belagavi, Bellary and Kalaburagi across the state and enlightened the people on the benefits of the CAA.

"As social media is all-pervasive with greater reach and better impact, we are also reaching about one crore people of all ages through Kannada, Hindi and English script, messages and audio/video clips in the state during the fortnight campaign," added Kateel.
