Obesity May Leads to Reduced Cognitive Function

People who are overweight do not perform as well on tests of memory and visuospatial ability compared to those with an average weight.

Being obese in older age may lead to poor brain health as higher waist-hip ratio was associated with reduced cognitive function, according to a study.

The association could be explained by an increased secretion of inflammatory markers by belly fat, which has been previously associated with a higher risk of impaired cognition.

Previous studies showed that people who are overweight do not perform as well on tests of memory and visuospatial ability compared to those with an average weight.

For the study, the researchers recruited more than 200 participants who were 60 years and older and used Facebook for at least a year.

“While we have known for some time that obesity is associated with negative health consequences, our study adds to emerging evidence suggesting that obesity and where we deposit our excess weight could influence our brain health. This has significant public health implications,” said Conal Cunningham from Trinity College Dublin in Ireland.

For the study, published in the British Journal of Nutrition, the team analysed data from over 5,000 individuals.

These findings may have significant implications as the global prevalence of dementia is predicted to increase from 24.3 million in 2001 to 81.1 million by 2040.

Reducing obesity could offer a cost-effective public health strategy for the prevention of cognitive decline, the researchers noted. (IANS)

Obesity During Pregnancy May up Kids’ Risk of Epilepsy

In addition, complications related to neonatal-asphyxia -- the state of being deprived of oxygen --, as well as less severe neonatal complications, were also independently associated with increased risk of childhood epilepsy

Women who are overweight or obese during their pregnancy may significantly increase the risk for children developing epilepsy, a study has showed.

Epilepsy is a disorder in which nerve cell activity in the brain is disturbed, causing seizures.

The results showed that the risk of epilepsy increased by 11 per cent in children of overweight mothers (BMI of 25 to less than 30) compared with children and normal-weight mothers.

While women with grade I obesity (BMI 30 to less than 35) increased the risk 20 by per cent, those with grade II obesity (BMI 35 to less than 40) raised the risk by 30 per cent.

The risk for children with mothers in the grade III obesity category was 82 per cent.

“Given that overweight and obesity are potentially modifiable risk factors, prevention of obesity in women of reproductive age may be an important public health strategy to reduce the incidence of epilepsy,” said Neda Razaz, from the Karolinska Institutet in Sweden.

Maternal overweight and obesity may increase the risk of brain injury, leading to a range of neurodevelopmental disorders, or that maternal obesity might affect neurodevelopment through obesity-induced inflammation, leading to epilepsy, the researchers argued, in the article published online by JAMA Neurology.
