Why are we ticklish?

It is no coincidence that the most ticklish parts of the body are also the most vulnerable, like the neck, the ribs and the stomach.

Why are we ticklish?The only people in this world who haven’t been tickled are probably infants who have not yet achieved this rite of passage. Everyone has giggled, gasped for breath, and gone into convulsions during a tickling attack, whether they still love tickling or grew to hate it. It’s one of those things that are hard to […]

High-fat diets impairs brains ability to control appetite response

Obesity, researchers point out, is frequently characterised by leptin resistance, which means that the body is unable to ‘read’ the signals sent by the hormone that typically curbs appetite

High-fat diets impairs brains ability to control appetite responseHow do we know when to eat, and when to stop eating? Easy: we feel hungry, so we know it’s time for a meal. Then, when we feel full, we know it’s time to put down the cutlery and get on with our day. These states of hunger and satiety occur due to the brain’s […]

Lack of sleep changes your personality

In 1959, New York DJ Peter Tripp stayed awake 200 hours for charity. While the impact of his 'wakeathon' was far more dramatic than expected, doctors are still learning about why it changed him so much. Jakke Tamminen, a psychology lecturer at Royal Holloway, explains

Lack of sleep changes your personalityIn 1959, Peter Tripp, a popular New York DJ, pledged to stay awake for 200 hours for charity while continuing to host his radio show. Studies into sleep deprivation were rare at the time so no one knew what to expect. This made it a major event, not only for Tripp’s millions of listeners, but […]

#WorldAlzheimersDay: Anxiety could be an early indicator of Alzheimer’s disease

As anxiety is common in older people, rising anxiety symptoms may prove to be most useful as a risk marker in older adults with other genetic, biological or clinical indicators of high Alzheimer’s disease risk

#WorldAlzheimersDay: Anxiety could be an early indicator of Alzheimer’s diseaseAccording to a recent study, anxiety may be an early indicator of Alzheimer’s disease in older adults. The findings support the hypothesis that neuropsychiatric symptoms could represent the early manifestation of Alzheimer’s disease in them. Alzheimer’s disease is a neurodegenerative condition that causes the decline of cognitive function and the inability to carry out daily […]

Baby teeth could offer clues to detect autism and its causes

Scientists have created a new test which can identify whether a child has autism by looking at their baby teeth. The paper is centred around how children metabolize metals, which are critical to neurodevelopment in early life. An imbalance in this process has previously been linked with autism spectrum disorder (ASD)

Baby teeth could offer clues to detect autism and its causesA close examination of baby teeth is giving new insight into the roots of autism-and ways to spot it early. The research suggests that the way infants metabolise two nutrients-zinc and copper-may predict who will develop the condition. “We have identified cycles in nutrient metabolism that are apparently critical to healthy neurodevelopment, and are dysregulated […]

Heart-healthy diet linked to bigger brain volume, reveals new research

You go to the gym to make your muscles bigger, but what if you want to bulk up your brain to help you stay sharp? Researchers suggests you might want to head to the produce aisle. People who ate diets full of vegetables, fruits, nuts and fish had bigger brains than their less well-nourished counterparts

Heart-healthy diet linked to bigger brain volume, reveals new researchThe same diet that doctors recommend for dodging heart disease also may help preserve brain tissue, a new study conducted in the Netherlands found. Researchers scrutinised diet surveys from more than 4,200 people with an average age of 66 and ranked the quality of their diets on a scale of 0 to 14. A score […]

Delhi: Doctors extract 100 tapeworm eggs from girl’s brain, without surgery

Doctors at Fortis Memorial Research Institute remove 100 tapeworm eggs from an eight -year-old girl’s brain. The child used to have severe headaches, epileptic seizures,  breathlessness, difficulty in walking and swelling of the brain. The patient was treated non-surgically for a condition called neurocysticercosis

Delhi: Doctors extract 100 tapeworm eggs from girl’s brain, without surgeryIn a startling discovery, doctors at Fortis Memorial Research Institute found 100 tapeworm eggs in the brain of an eight-year-old girl.Dr Praveen Gupta, Director, Neurology at Fortis Memorial Research Institute and his team treated her for a period of six months using non-surgical techniques to remove the tapeworm eggs. The patient had been on steroid […]

Consuming leafy green vegetables can keep your brain young, prevent dementia

The findings suggest this benefit is likely from important nutrients found in these vegetables, such as foliate, lutein and nitrate, which were also associated with slower cognitive decline. This may be because the nutrients protect against inflammation, stress and damaging changes in the brain

Consuming leafy green vegetables can keep your brain young, prevent dementiaEating plenty of leafy green vegetables every day could ward off dementia in later life, new research suggests. A study of elderly people found those who ate around one serving of leafy greens each day had brains that were the equivalent of 11 years younger than those who never or rarely ate the vegetables. A […]

Recent advancements in cochlear implants

Dr Dillon D’souza, a Consultant ENT and Head and Neck surgeon attached to Jaslok hospital, Breach Candy Hospital and Desa’s Hospital, shares how the cochlear implants work and what recent technical advancements it has made in the recent times

Recent advancements in cochlear implantsWhat is a cochlear implant? A cochlear implant is an electronic device that takes over the work of the human ear and converts sounds to electrical signals that the brain understands as sounds. It delivers them to the brain via hearing nerve after fine-tuning the sound much like a graphic equaliser on a music system, […]

General anesthetic may harm brain development in children

The study firms up earlier conclusions that significant exposure to general anesthetics during development negatively impacts the growing brain. Because of the wide-ranging implications of the study, more research will no doubt follow hot on its heels

General anesthetic may harm brain development in childrenBut over recent years, some concerns have been raised regarding this. So much so that in April 2017, the U.S. Food and Drug Administration (FDA) warned of potential risks to developing brains. They write that “repeated or lengthy use of general anesthetic and sedation drugs […] in children younger than 3 years or in pregnant […]
