Sports-related concussions (SRC) may not be linked to long-term cognitive problems for non-professional players, according to a study on Wednesday.   The research, published in the Journal of Neurology, Neurosurgery and Psychiatry (JNNP), showed that people who reported having any SRC in their lives performed marginally better cognitively than those with no concussion history. In fact, participants who had sustained SRC actually performed better cognitively in some domains than those who had never had a concussion, suggesting that sports activity may have preventive effects. Led by researchers from the University of New South Wales, Australia, an international team from the US, and the UK analysed data from over 15,000 participants aged 50 to 90. The research aimed to comprehend cogniti...

Night owls -- a person who is habitually active or wakeful at night -- tend to have a higher body mass index (BMI), larger waists, and more hidden body fat and thus are almost 50 per cent more likely to develop type 2 diabetes (T2D) than those who go to bed earlier, shows new research on Monday. Previous studies have indicated that late chronotype -- people who prefer to go to bed late and wake up late -- live an unhealthy lifestyle, and are at higher risk of obesity and metabolic disorders including type 2 diabetes. The new study showed that a late chronotype had a 46 per cent higher risk of developing diabetes, which suggests that the increased risk of T2D can`t be explained by lifestyle alone. "We believe that other mechanisms are also at play," said lead researcher Dr. Jeroen van de...

People suffering from poor gut health with constipation and nausea for a long period may signal the risk of developing Parkinson`s disease, according to a study that shows the neurological disorder may begin in the gut and not the brain.  Parkinson`s disease is a progressive neurodegenerative disorder. It affects an estimated 8.5 million people worldwide; and is majorly characterised by tremors, stiffness, and loss of balance. The study, published in the journal Cerebral Cortex, found that a history of damage to the lining of the upper gastrointestinal (GI) tract has a 76 per cent higher chance of developing Parkinson`s. Trisha S. Pasricha, a neurogastroenterologist at the Beth Israel Deaconess Medical Center (BIDMC) in the US noted that science is yet to completely unravel how the gut ...

The rising consumption of processed and packaged food in India will likely affect health outcomes and policies may be required to regulate the nutritional content of these foods and promote healthier alternatives, a government paper has stressed.  According to the paper, titled ‘Changes in India’s Food Consumption and Policy Implications,’ by the Economic Advisory Council (EAC) to the Prime Minister, across regions and consumption classes, “we observe a significant increase in the share of household expenditure on served and packaged processed food”. This increase was universal across the classes but more pronounced for the country`s top 20 per cent of households and significantly more in urban areas. “While food processing is a growth sector and a significant creator of jobs, this risi...

Limiting the use of mobile phones in making and taking calls may help reduce the risk of cardiovascular diseases, according to a top neurologist. Taking to social media platform X, Dr. Sudhir Kumar from Indraprastha Apollo Hospitals, said that limiting mobile phone use, along with other healthy lifestyle measures may be good for boosting heart health. “It is useful to limit the duration of taking and making calls in order to reduce the risk of CVDs,” said Kumar. “Ensure good sleep and minimise psychological stress,” he added, while also suggesting to quit smoking. He said this citing a recent Chinese study, published in the Canadian Journal of Cardiology, which showed an increased association between mobile phone use and heart diseases like stroke, coronary artery disease, atrial fibri...

Regular consumption of junk food -- rich in sugar, salt, and fat -- hampers micronutrient absorption in the body and leads to nutrient deficiencies, affecting overall health, said experts on Saturday. National Nutrition Week is observed annually from September 1 to September 7. The theme this year is ‘Nutritious Diets for Everyone’. A nutritional deficiency occurs when the body doesn`t get enough of a nutrient from food or has trouble absorbing it. Junk foods typically lack the necessary vitamins, minerals, and fiber that facilitate proper digestion and nutrient absorption. Deficiencies can affect digestion, and bone growth, cause skin disorders, anaemia, dementia, nervous system damage, and more. “Consuming junk foods regularly can significantly hinder micronutrient absorption, leadin...

Long-term exposure to fine particulate matter (PM2.5) air pollution is linked to a higher risk of infertility in men, according to a Danish study.  The study led by researchers at the Nord Universitet in Denmark throws light on a significant worldwide health issue, infertility which affects one in every seven couples. Studies on sperm quality and the success of fertility treatments have found negative correlations with particulate air pollution; however, results on fecundability, or the probability of becoming pregnant, have been inconsistent, and no research has looked into the impact of transportation noise on infertility in men and women. The study, published in the journal BMJ, found that prolonged exposure to PM2.5 is associated with a higher risk of infertility in men. The team i...

Have you ever been faced with a choice at a crossroads? A recent study may have finally figured out what our brains are doing when we indulge in spontaneous behaviour.  The Brain Institute at Chapman University in California, US, conducted a study on how the brain triggers impulsive behaviour like leaping off a high-dive platform or coming up with novel ideas. They concentrated on a phenomenon where the human brain becomes more active one or two seconds before it takes action. Since the 1960s, neuroscientists have believed that this ramping is an indication that our brain is getting ready to act following the completion of an unconscious, premeditated decision. However, the new research offers another answer. The team found that many rapidly fluctuating neurons -- brain cells, interact...

Spinal cord injury, one of the most devastating injuries to the human body, is becoming more common than ever, said experts on Thursday. Spinal Cord Injury Day is celebrated each year on September 5 to bring about awareness about the spinal cord. The spine is the backbone of the human body and maintaining its health is crucial for overall well-being, said the health experts. “With the increasing prevalence of sedentary lifestyles, poor posture habits, and the rise of technology use, spinal issues have become more common than ever,” Dr Arvind Kulkarni, Head - Spinal Surgeon, Mumbai Spine Scoliosis and Disc Replacement Centre, told IANS. The incidence of spinal cord injury in India is estimated to be around 20 per million with 2,500 fresh cases added every year. The condition is no longe...

Dietary deficiency, which can be prevented, is a major risk factor for osteoporosis in women, said experts on Thursday. National Nutrition Week is observed annually from September 1 to September 7. The theme this year is ‘Nutritious Diets for Everyone’. Osteoporosis is a bone disease that weakens bones, making them thinner and more susceptible to fractures. The disease majorly affects women, particularly after menopause. Six crore people in India reportedly have osteoporosis and 80 per cent of them are women. A decline in oestrogen levels -- the female hormone essential for healthy bones -- directly affects bone density explains why women are more at risk. “The most important cause of osteoporosis is a dietary deficiency, which can be prevented with a recommended dietary allowance of 1...
