Not a single Dalit vote should go to casteist BJP in Karnataka: Jignesh Mevani

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.

Mysuru, Jan 28: The Second Additional District and Sessions Court on Monday granted anticipatory bail to B Nalini, who displayed the ‘Free Kashmir’ placard during a protest, and also to Maridevaiah, the organiser of the protest.

Nalini and Maridevaiah had applied for bail as Jayalakshmipuram police had booked them under sedition charges. Nalini had displayed the placard during a protest at Manasagangotri, the University of Mysore campus, recently. The court, which took up the case on January 24, had kept the order pending.

The court directed the accused to submit their passport to the court and a bond for a sum of Rs 50,000. The court also directed them to be present before the police, whenever needed.

Meanwhile, the Mysuru Bar Association has decided to take measures against the association members who are in favour of Nalini. Seventy-five members, seeking to represent Nalini, have withdrawn their support, the association secretary B Shivanna said. The association has suspended advocates Manjula Manasa and P P Baburaj.

New Delhi, Jan 12: In a shocking revelation, one unemployed person committed suicide every hour during 2018 when a total of 1,34,516 suicides, including 92,114 male and 42,391 female, were reported in the country, NCRB's "Suicide in India 2018" says.

The latest data, issued by the National Crime Records Bureau (NCRB), which comes under Ministry of Home Affairs, last week reveals that a total of 12,936 unemployed persons committed suicide in 2018, which accounted for 9.6 per cent of the total suicides, and were of aged below 18 years to above 60 years.

Those below 18 years include 31 males and nine females while those between 18 and 30 years comprise 1,240 male and 180 female. A total of 868 male and 95 female were aged between 30 and 45 years. A number of 237 males and 21 females were aged between 45 and 60 years while 2,431 males and 310 females were above 60 years.

Of the total suicides by unemployed persons, males are 10,687 while the females are 2,249.

The highest number of suicides - 12.3 per cent - committed by unemployed persons were in Kerala (1,585 out of 12,936 suicides), 12.2 per cent in Tamil Nadu (1,579), 9.7 per cent in Maharashtra (1,260 suicides), 8.5 per cent in Karnataka (1,094 suicides) and 7 per cent in Uttar Pradesh (902 suicides).

"Each suicide is a personal tragedy that prematurely takes the life of an individual and has a continuing ripple effect, dramatically affecting the lives of families, friends and communities. Every year, more than 1 lakh people commit suicide in our country. There are various causes of suicides like professional/career problems, sense of isolation, abuse, violence, family problems, mental disorders, addiction to alcohol, financial loss, chronic pain etc," says the NCRB adding it collects data on suicides from police recorded suicide cases.

As per the NCRB, rate of suicides has been calculated using projected population for the non-census years whereas for 2011, the population of the Population Census 2011 was used.

The NCRB data says that a total of 1,34,516 suicides were reported in the country during 2018 showing an increase of 3.6 per cent in comparison to 2017 and the rate of suicides has increased by 0.3 during 2018 over 2017.

Government servants accounted for 1.3 per cent (1,707 out of 1,34,516) of the total suicide victims as compared to 6.1 per cent (8,246 out of 1,34,516) of total victims from Private Sector Enterprises.

Employees from Public Sector Undertakings formed 1.5 per cent (2,022 out of 1,34,516) of the total suicide victims, whereas students and unemployed victims accounted for 7.6 per (10,159 victims) of total suicides. Self-employed category accounted for 9.8 per cent of total suicide victims (13,149 out of 1,34,516).

A total of 10,349 persons involved in farming sector (consisting of 5,763 farmers and cultivators and 4,586 agricultural labourers) have committed suicide during 2018, accounting for 7.7 per cent of total suicides victims (1,34,516) in the country.

A total of 11 transgenders have committed suicide in which three were daily wage earners, one each were 'professionals and salaried persons' and 'unemployed persons' while six falls under 'Other Persons'.
